Abstract
The invention relates to a method for introducing air and oxygen into a diesel engine at high pressure. According to the technical scheme provided by the invention, the method for introducing the air and the oxygen into the diesel engine at the high pressure comprises the following steps of: introducing the air under the atmosphere of more than 4MPa into an oil cylinder of the diesel engine through an air inlet pipe, and introducing pure oxygen into the oil cylinder of the diesel engine through the air inlet pipe simultaneously, so that the volume ratio of the oxygen to the air in the oil cylinder of the diesel engine is improved by more than one fourth after the air is introduced into the oil cylinder of the diesel engine each time. By the method, the compression ratio of the oil cylinder of the diesel engine during work application each time can be greatly improved, combustion temperatures in the oil cylinder of the diesel engine are improved, and the indirect ignition speed of diesel oil is improved, so that the diesel oil which is ejected each time in the oil cylinder of the diesel engine is completely combusted; and the method is low in environment pollution and is relatively low in fuel oil consumption.
Description
Technical field
The present invention relates to technical field of internal combustion engines, the oxygen method is advanced in especially a kind of diesel engine high-pressure air inlet.
Background technique
Fire is divided into solid combustion, liquid burning and gaseous combustion in the burning of occurring in nature, and the burning kind exists: quiet burning and moving burning, ignition way have directly lights and deliberately lights, and directly lights and can be divided into and deliberately light and light naturally.Burning all needs to possess corresponding condition, and fire is to human contribute light, heat and velocity of combustion.There is moving burning in the burning of diesel oil in diesel engine, and ignition way exists directly to be lighted and light indirectly.What diesel engine was wanted is velocity of combustion.The diesel combustion condition is: diesel particulate air temperature energy high, that directly light little, that enter in the firing chamber wants movement velocity big, diesel engine piston can not surpass the speed that diesel oil is lighted indirectly.In the diesel engine, if the speed of lighting indirectly is fast, the gas temperature height can be strengthened diesel oil and become gas.
At present, spray into the interior diesel particulate of diesel engine by varying, if line up by its order from small to large, one-level is for example arranged, secondary, three grades, level Four, Pyatyi, six grades and seven grades, these seven grades, Piston Compression to the cylinder the space hour, one-level, the diesel particulate of secondary and three grades is directly lighted, and makes that big slightly level Four and Pyatyi diesel particulate lighted indirectly, and six grades and seven grades are because the particle maximum, do not have time enough or oxygen to make its burning, diesel engine is exhaust, so, the gas color of diesel engine discharge now is a black, and with pungent taste, black part is divided into carbon, and pungent taste partly is a diesel oil.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the oxygen method is advanced in the diesel engine high-pressure air inlet that provide a kind of combustion efficiency that can improve diesel oil, improve compression ratio, as far as possible makes each injection enter the diesel oil perfect combustion in the diesel engine oil cylinder.
According to technological scheme provided by the invention, described diesel engine high-pressure air inlet is advanced the oxygen method and is comprised: feed atmospheric air more than 4 by suction tude in the diesel engine oil cylinder, in the diesel engine oil cylinder, feed pure oxygen by suction tude simultaneously, make that the shared volume ratio of oxygen is increased to more than 1/4 in the gas of diesel engine oil cylinder after the each air inlet of diesel engine oil cylinder.
As preferably, cross suction tude and in the diesel engine oil cylinder, feed 4 ~ 6 atmospheric air.
As preferably, in the diesel engine oil cylinder, feed pure oxygen by suction tude, make that the shared volume ratio of oxygen is increased to 1/4 ~ 1/3 in the gas of diesel engine oil cylinder after the each air inlet of diesel engine oil cylinder.
Compression ratio when the present invention can improve burning chamber of diesel engine greatly and does work at every turn improves the indoor combustion temperature of diesel combustion, has improved the indirect lighting-up rate of diesel oil, makes each diesel oil perfect combustion of spraying in the diesel engine oil cylinder; Pollution to environment is very little, and fuel consume is less.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
Diesel engine high-pressure air inlet of the present invention is advanced the oxygen method and is specially: feed atmospheric air more than 4 by suction tude in the diesel engine oil cylinder, in the diesel engine oil cylinder, feed pure oxygen by suction tude simultaneously, make that the shared volume ratio of oxygen is increased to more than 1/4 in the gas of diesel engine oil cylinder after the each air inlet of diesel engine oil cylinder.
Cross suction tude and feed 4 ~ 6 atmospheric air in the diesel engine oil cylinder, such requirement better realizes.
Feed pure oxygen by suction tude in the diesel engine oil cylinder, make that the shared volume ratio of oxygen is increased to 1/4 ~ 1/3 in the gas of diesel engine oil cylinder after the each air inlet of diesel engine oil cylinder, such requirement better realizes.
Realization feeds 4 ~ 6 atmospheric air by suction tude in the diesel engine oil cylinder, can adopt multiple scheme, for example:
1, the flywheel on the crankshaft of diesel engine is transformed into the impeller of the brilliant formula high-pressure air of charcoal compressor pump;
2, install many turbochargers additional at engine flywheel, each turbocharger drives by the flywheel on the crankshaft of diesel engine.
After feeding 4 ~ 6 atmospheric air by suction tude in the diesel engine oil cylinder; like this; the air total amount that enters after each air inlet improves greatly; improved the ratio between oxygen and the diesel oil; compression ratio after the each compression of diesel engine oil cylinder obviously becomes big; improved the diesel engine oil cylinder temperature; greatly improved moving burning energy in the diesel engine oil cylinder; greatly satisfied the condition of diesel combustion; make the one-level in the diesel oil of each injection; the diesel particulate of secondary and three grades is directly lighted remaining level Four; Pyatyi; six grades and seven grades of diesel particulates are because cylinder temperature is high, and moment strengthens and is gas; reinforcement is lighted by moment indirectly for the diesel oil of gas; like this, the speed that diesel oil is lighted has indirectly surpassed the movement velocity of diesel engine piston, has solved the difficult problem that diesel oil can not perfect combustion; save the consumption of diesel oil, protected environment.
Using existing model is that 100 diesel applications method of the present invention is tested, in the diesel engine oil cylinder, feed 4 ~ 6 atmospheric air by suction tude, in the diesel engine oil cylinder, feed pure oxygen by suction tude simultaneously, make after the each air inlet of diesel engine oil cylinder, the shared volume ratio of oxygen is increased to 1/4 ~ 1/3 in the gas of diesel engine oil cylinder, test obtains: outlet pipe mouth of pipe smoke-free and tasteless illustrates that diesel oil perfect combustion to the greatest extent.
