Summary of the invention:
The present invention can solve the problem emitting white cigarette or black smoke when compression ignition engine low-pressure low-temperature ignition problem and compression ignition engine start or accelerate.
A kind of compression ignition engine.Compression ignition engine structure mainly comprises: the air-cooled coil pipe of crankcase, bent axle, crank, piston, cylinder, cylinder head, intake valve, exhaust valve, outlet pipe, air filter, booster fan, cylinder, fuel tank, fuel pump.Organic oil lubrication in crankcase, steam-cylinder lagging has the air-cooled coil pipe of cylinder.Air is pressurized blower fan and is blown into the air-cooled coil pipe of cylinder after air filter, then after an electromagnetic air valve and a threeway, enters suction tude, enters cylinder finally by the intake valve opened.The pressurized air that air compressor extrudes enters compressed air reservoir after one-way valve.Compressed air reservoir is equipped with pressure transducer.Enter pressurized air bag from compressed air reservoir pressurized air out, pressurized air bag is built with pressurized air electric heater, and the outer surface cover of pressurized air bag has pressurized air combustion heater.Contract out the pressurized air that comes after a pressurized air gives vent to anger solenoid valve from pressurized air, enter threeway from another entrance of threeway, enter suction tude again from threeway pressurized air out, enter cylinder finally by the described intake valve opened.Cylinder is built with cellular three-element catalytic alloy network, and cellular three-element catalytic alloy network shape, as straw hat, scribbles the edge clamping of the straw hat of heat insulation layer between cylinder port and cylinder head.Fuel pump extracts fuel oil and delivers in liquid fuel room from fuel tank, and the fuel oil of liquid fuel indoor is installed in the liquid fuel electric heater heating of liquid fuel indoor or is enclosed in the liquid fuel combustion heater heating in the outdoor face of liquid fuel.Fuel solenoid valve is opened in energising, be vaporized after the high temp oil-fired exceeding vapourizing temperature enters vaporizing chamber, the gasified fuel infrared ray electric light wave heater be installed in vaporizing chamber of the gasified fuel in vaporizing chamber continues heating or the vaporizing chamber combustion heater be enclosed in outside vaporizing chamber continues heating.In expansion stroke, gasified fuel solenoid valves is opened, gasified fuel sprays into cylinder from gasified fuel nozzle.
The low-pressure low-temperature igniting of compression ignition engine and the method for elimination tail gas pollution.Start air compressor, the pressurized air that air compressor extrudes enters compressed air reservoir and is stored after one-way valve.When the compressed-air actuated pressure that pressure transducer detects in compressed air reservoir reaches setting high pressure, stop the electricity of air compressor, one-way valve can stop the pressurized air in compressed air reservoir to be leaked in air compressor.When pressure transducer detects compressed-air actuated pressure in compressed air reservoir lower than setting low value, restart air compressor.Pressurized air bag is entered from compressed air reservoir pressurized air out, use the pressurized air inside pressurized air electric heater heated compressed air bag before an engine is started, compressed air temperature sensor stops the electricity of pressurized air electric heater after detecting that compressed-air actuated temperature reaches set temperature value.When motor normally runs, the pressurized air inside the pressurized air combustion heater heated compressed air bag that the outer surface cover of pressurized air bag has.Before engine start, first start fuel pump, fuel pump extracts fuel oil and delivers in liquid fuel room from fuel tank, and fuel oil is installed in the liquid fuel electric heater heating of liquid fuel indoor in liquid fuel indoor.After liquid fuel temperature transducer detects that liquid fuel is heated to setting temperature, fuel solenoid valve is opened in energising, is vaporized after the high temp oil-fired exceeding vapourizing temperature enters vaporizing chamber.The gasified fuel infrared ray electric light wave heater that the fuel oil of vaporization is energized at vaporizing chamber continues heating.Gasified fuel temperature transducer stops the electricity of gasified fuel infrared ray electric light wave heater after detecting that the temperature of gasified fuel reaches setting value.When motor normally runs, fuel pump extracts fuel oil and delivers in liquid fuel room from fuel tank, and fuel oil is enclosed in the liquid fuel combustion heater heating in the outdoor face of liquid fuel in liquid fuel indoor.Fuel solenoid valve is opened in energising, is vaporized after the high temp oil-fired exceeding vapourizing temperature enters vaporizing chamber, and the vaporizing chamber combustion heater that the fuel oil of vaporization is enclosed in outside vaporizing chamber inside vaporizing chamber continues heating.During ato unit, first open pressurized air give vent to anger solenoid valve and close electromagnetic air valve.Suction stroke just intake valve is opened, and the high temperature compressed air inside pressurized air bag enters cylinder through opening the pressurized air intake valve opened in solenoid valve and suction stroke of giving vent to anger.IC Intake Valve Closes in compression stroke, the high temperature air in piston compression cylinder, compressed air temperature when piston reaches dead point in cylinder reaches peak, exceedes the burning-point of gasified fuel, and compression stroke terminates.In expansion stroke, gasified fuel solenoid valves is opened, high-temperature evaporation fuel oil sprays into cylinder from gasified fuel nozzle.Due to inspiration in suction stroke is high temperature air, so only need very low compression ratio in compression stroke, compressed-air actuated temperature just can be made to exceed gasified fuel burning-point.High-temperature evaporation fuel oil due to what spray in expansion stroke, need to absorb vaporization heat after entering cylinder without available engine jetting liquid fuel oil could vaporize the process of scattering, and reduce the phenomenon appearance of the temperature of cylinder compressed air because needing absorption vaporization heat; So only need very low compression ratio in compression stroke, just the gasified fuel sprayed in cylinder can lighted at the beginning of expansion stroke.In addition, cylinder, built with cellular three-element catalytic alloy network, is sprayed onto the gasified fuel on cellular three-element catalytic alloy network, just can be lighted by the cellular three-element catalytic alloy network of 400 degrees Celsius under the effect of catalyzer.Also be because the effect of catalyzer, still can be lighted by the cellular three-element catalytic alloy network of high temperature when gasified fuel concentration is extremely low.This means that motor is in uncharge situation, only need to spray into few gasified fuel and just can maintain idle running.The cotton yarn wick of kerosene lamp can be lighted under low temperature, and the cotton yarn wick lighted is lighted kerosene again.After gasified fuel is lighted by the cellular three-element catalytic alloy network of high temperature, the gasified fuel of the grid combustion of cellular three-element catalytic alloy network gets up heat storage, and the temperature of cellular three-element catalytic alloy network raises fast; Because cellular three-element catalytic alloy network specific heat is little, and the adiabatic membrane at cellular three-element catalytic alloy network edge makes the heat of cellular three-element catalytic alloy network can not be delivered on cylinder and cylinder sleeve, so cellular three-element catalytic alloy network is heated to very high temperature soon, then more gasified fuel is just had to be lighted, cellular three-element catalytic alloy network is lighted gasified fuel just as the cotton yarn wick of kerosene lamp at very not high temperature, so also can reduce the compression ratio in compression stroke.After motor normally runs, air is pressurized in the air-cooled coil pipe of blower fan press-in cylinder after air filter.Air is heated by the cylinder wall of high temperature in the air-cooled coil pipe of cylinder, then enters suction tude through the electromagnetic air valve opened, and the intake valve then by opening in suction stroke enters cylinder.High temperature air in cylinder is in compression stroke, raised further by compression temperature, so do not need very high compression ratio just can allow the high temperature compressed air of cylinder interior that cellular three-element catalytic alloy network is heated to very high temperature, exceedes the burning-point of gasified fuel.High-temperature evaporation fuel oil due to what spray in expansion stroke, the phenomenon that absorption vaporization heat could be vaporized is needed after not having available engine jetting liquid fuel oil to enter cylinder, and reduce the temperature of cylinder compressed air, so only need very low compression ratio, temperature in compression stroke and not bery high pressurized air, the gasified fuel sprayed in cylinder just can be lighted.Cylinder, built with cellular three-element catalytic alloy network, is sprayed onto the gasified fuel on cellular three-element catalytic alloy network, just can be lighted by the cellular three-element catalytic alloy network of 400 degrees Celsius under the effect of catalyzer.Also be because the effect of catalyzer, still can be lighted by the cellular three-element catalytic alloy network of high temperature when gasified fuel concentration is extremely low.This means that motor is in uncharge situation, only need to spray into few gasified fuel and just can maintain idle running.The cotton yarn wick of kerosene lamp can be lighted under low temperature, and the cotton yarn wick lighted is lighted kerosene again.After gasified fuel is lighted by the cellular three-element catalytic alloy network of high temperature, the gasified fuel of the grid combustion of cellular three-element catalytic alloy network gets up heat storage, and the temperature of cellular three-element catalytic alloy network raises fast; Because cellular three-element catalytic alloy network specific heat is little, and the adiabatic membrane at cellular three-element catalytic alloy network 29 edge makes the heat of cellular three-element catalytic alloy network can not be delivered on cylinder and cylinder sleeve, so cellular three-element catalytic alloy network is heated to very high temperature soon, then more gasified fuel is just had to be lighted, cellular three-element catalytic alloy network is lighted gasified fuel just as the cotton yarn wick of kerosene lamp at very not high temperature, so also can reduce the compression ratio in compression stroke.Because the burning of gasified fuel on cellular three-element catalytic alloy network is catalytic combustion, gasified fuel mainly burns in the aspect of cellular three-element catalytic alloy network, belong to the Thorough combustion under low temperature, seldom produce carbon monoxide, carbon microsphere and low molecular hydrocarbons, also seldom produce nitrogen oxide.In exhaust stroke, exhaust valve is opened, high temperature waste hot gas is through cellular three-element catalytic alloy network, and the carbon monoxide in waste hot gas, carbon microsphere and low molecular hydrocarbons are oxidized to carbon dioxide and water under the catalyst action of cellular three-element catalytic alloy network, then discharges from the exhaust valve opened.Waste hot gas is first through the gasified fuel inside the heat vaporized room of vaporizing chamber combustion heater, again through the liquid fuel inside liquid fuel combustion heater heating liquid fuel oil room, last waste hot gas is through the pressurized air inside pressurized air combustion heater heated compressed air bag.Owing to not needing water cooling, can make 90 degree of angles between the cylinder of motor, not point-blank, Engine torque increases, efficiency improves at the dead point of such piston movement.Due to the ejection of spray gasified fuel nozzle is gasified fuel, gasified fuel volume is more much larger than the volume of the liquid fuel of identical weight, the hole of the gasified fuel nozzle of ejection identical weight is more much larger than the hole of ejection liquid fuel, so adopt the hole of the gasified fuel nozzle of the compression ignition engine of common rail combustion technology to bore larger, the hole of such gasified fuel nozzle is just easy to processing.
Existing energy-saving diesel engine installs a cellular plane alloy catalytic net on the pit of piston base, the online burning of the cellular plane alloy catalytic of diesel oil on piston belongs to the burning of subsidiary combustion chamber, main combustion chamber be positioned at cylinder lower half portion, both near the part of cylinder head.And cellular three-element catalytic alloy network of the present invention is contained in the cylinder main combustion chamber above cylinder head, burning after diesel oil is sprayed on cellular three-element catalytic alloy network all belongs to catalytic combustion, and waste hot gas is all filtered by cellular three-element catalytic alloy network in exhaust stroke, carbon monoxide and carbon microsphere emit after being all oxidized to carbon dioxide.The diesel oil of existing energy-saving diesel engine belongs to ordinary combustion at the combustion manner of main combustion chamber, and belong to catalytic combustion in the burning that subsidiary combustion chamber cellular plane alloy catalytic is online, and waste hot gas does not have the cellular plane alloy catalytic net filtration on seawater in exhaust stroke.In the present invention, cellular three-element catalytic alloy network is near fuel nozzle, and the fuel oil of fuel nozzle ejection is lighted by the catalysis of high temperature cellular three-element catalytic alloy network.The cellular plane alloy catalytic net of existing energy-saving diesel motor is contained on piston, away from fuel nozzle, after the diesel oil that fuel nozzle sprays is lighted by high temperature compressed air, the cellular plane alloy catalytic net catalytic combustion of the diesel oil also do not burnt just on piston.
The compression ratio of existing diesel engine is 15: 1, and adopts diesel engine compression ratios of the present invention to drop to 5: 1.Use the car speed per hour of existing diesel engine, the highlyest can reach 80 kilometers/hour; And adopt the car speed per hour of diesel engine of the present invention, the highlyest can reach 160 kilometers/hour.Under any circumstance outlet pipe all can not over-emitting black exhaust to adopt the car of diesel engine of the present invention.
After existing straight spray petrol engine car compression stroke, first will spray once in the cylinder of light gasoline, then spray once dense gasoline in cylinder, spray into by spark ignitor the dense gasoline that in cylinder, spark plug is other, such spark plug is easy to carbon distribution, affects plug ignition.And the compression-ignited petrolic car of the present invention, cellular three-element catalytic alloy network can when 400 degrees Celsius, lower than gasoline burning-point, the light gasoline sprayed into is lighted, and burning very abundant.

three-element catalytic alloy network (29), be sprayed onto the gasified fuel on cellular three-element catalytic alloy network (29), just can be lighted by the cellular three-element catalytic alloy network (29) of 400 degrees Celsius under the effect of catalyzer, also be because the effect of catalyzer, still can be lighted by the cellular three-element catalytic alloy network (29) of high temperature when gasified fuel concentration is extremely low, this means that motor is in uncharge situation, only need to spray into few gasified fuel and just can maintain idle running, the cotton yarn wick of kerosene lamp can be lighted under low temperature, and the cotton yarn wick lighted is lighted kerosene again, after gasified fuel is lighted by the cellular three-element catalytic alloy network (29) of high temperature, the gasified fuel of the grid combustion of cellular three-element catalytic alloy network (29) gets up heat storage, and the temperature of cellular three-element catalytic alloy network (29) is raised fast, because cellular three-element catalytic alloy network (29) specific heat is little, and the adiabatic membrane at cellular three-element catalytic alloy network (29) edge makes the heat of cellular three-element catalytic alloy network (29) can not be delivered on cylinder (5) and cylinder sleeve (6), so cellular three-element catalytic alloy network (29) is heated to very high temperature soon, then more gasified fuel is just had to be lighted, cellular three-element catalytic alloy network (29) is lighted gasified fuel just as the cotton yarn wick of kerosene lamp at very not high temperature, so also can reduce the compression ratio in compression stroke, after motor normally runs, air is pressurized in blower fan (11) the press-in air-cooled coil pipe of cylinder (12) after air filter (10), air is heated by the cylinder of high temperature (5) wall in the air-cooled coil pipe of cylinder (12), electromagnetic air valve (27) again through opening enters suction tude, and the intake valve then by opening in suction stroke enters cylinder (5), high temperature air in cylinder (5) is in compression stroke, raised further by compression temperature, so do not need very high compression ratio just can allow the high temperature compressed air of cylinder (5) the inside that cellular three-element catalytic alloy network (29) is heated to very high temperature, exceedes the burning-point of gasified fuel, high-temperature evaporation fuel oil due to what spray at the beginning of expansion stroke, the phenomenon needing absorption vaporization heat to vaporize after not having available engine jetting liquid fuel oil to enter cylinder (5) occurs, and reduce the temperature of cylinder (5) compressed air, because cylinder (5) is built with cellular three-element catalytic alloy network (29), be sprayed onto the gasified fuel on cellular three-element catalytic alloy network (29), just can be lighted by the cellular three-element catalytic alloy network (29) of 400 degrees Celsius under the effect of catalyzer, also be because the effect of catalyzer, still can be lighted by the cellular three-element catalytic alloy network (29) of high temperature when gasified fuel concentration is extremely low, this means that motor is in uncharge situation, only need to spray into few gasified fuel and just can maintain idle running, the cotton yarn wick of kerosene lamp can be lighted under low temperature, and the cotton yarn wick lighted is lighted kerosene again, after gasified fuel is lighted by the cellular three-element catalytic alloy network (29) of high temperature, the gasified fuel of the grid combustion of cellular three-element catalytic alloy network (29) gets up heat storage, and the temperature of cellular three-element catalytic alloy network (29) is raised fast, because cellular three-element catalytic alloy network (29) specific heat is little, and the adiabatic membrane at cellular three-element catalytic alloy network (29) edge makes the heat of cellular three-element catalytic alloy network (29) can not be delivered on cylinder (5) and cylinder sleeve (6), so cellular three-element catalytic alloy network (29) is heated to very high temperature soon, then more gasified fuel is just had to be lighted, cellular three-element catalytic alloy network (29) is lighted gasified fuel just as the cotton yarn wick of kerosene lamp at very not high temperature, so also can reduce the compression ratio in compression stroke, so only need very low compression ratio, very low compressed air temperature in compression stroke, just can light and spray into the inner gasified fuel of cylinder (5), because the burning of gasified fuel on cellular three-element catalytic alloy network (29) is catalytic combustion, gasified fuel mainly burns in the aspect of cellular three-element catalytic alloy network (29), belong to the Thorough combustion under low temperature, little generation carbon monoxide, carbon microsphere and low molecular hydrocarbons, also seldom produce nitrogen oxide, in exhaust stroke, exhaust valve is opened, high temperature waste hot gas is through cellular three-element catalytic alloy network (29), carbon monoxide in waste hot gas, carbon microsphere and low molecule are oxidized to carbon dioxide and water vapor under the catalyst action of the cellular three-element catalytic alloy network (29) of hydrocarbon, then discharge from the exhaust valve opened (8), waste hot gas is first through the gasified fuel of the inside, vaporizing chamber combustion heater (18) heat vaporized room (17), again through the liquid fuel of liquid fuel combustion heater (16) heating liquid fuel oil room (15) the inside, the last waste hot gas of waste hot gas is through the pressurized air of pressurized air combustion heater (25) heated compressed air bag (24) the inside, owing to not needing water cooling, can make 90 degree of angles between the cylinder (5) of motor, not point-blank, Engine torque increases, efficiency improves at the dead point that such piston (4) moves, what spray due to oil spout vapour lock (28) is gasified fuel, the gasified fuel of identical weight is more much larger than the volume of liquid fuel, the hole of the gasified fuel nozzle (28) of ejection identical weight is more much larger than the hole of ejection liquid fuel, so adopt the hole of the gasified fuel nozzle (28) of the compression ignition engine of common rail combustion technology to bore larger, the hole of such gasified fuel nozzle (28) is just easy to processing.
