Abstract
The invention relates to a diesel engine (internal-combustion engine) separated and combined type fuel supply system, which is technically energy-saving and environmentally-friendly. The existing diesel engines are mainly used on automobiles, power generator units and the like which have the characteristics of original rotating speed maintenance and unfixed load capacity. If the automobiles maintain the original rotating speed, the automobiles are on heavy-load and no-load and the load capacities of the automobiles are different; and if grid power is cut off and hotels use diesel engine power generator units to maintain the original rotating speed, the load capacities are different under the conditions that the climate is hot and the climate is comfortable. When the original rotating speed of the existing diesel engines is maintained and the load capacity is decreased, fuel consumption and exhaust emission cannot be decreased. The diesel engine (internal-combustion engine) separated and combined type fuel supply system overcomes the defects of the existing diesel engines, can stop fuel supply to one part of cylinders to enable the cylinders to stop doing work and can continuously supply fuel to the other part of cylinders to enable the cylinders to continuously do work according to the work balance requirements of the diesel engines, so that the functions of maintaining the original rotating speed of the diesel engines, adjusting power output and decreasing the fuel consumption and exhaust emission are realized.
Description
Technical field
The present invention relates to a kind of diesel engine (internal-combustion engine) separating-closing type fuel oil supply system, specifically a kind of multi-cylinder engine keeps former rotating speed: the energy-saving and environmental protection technology of the horsepower output of adjusting a wage scale, the fuel consumption of adjusting a wage scale, the discharge amount of exhaust gas of adjusting a wage scale.
Background technique
At present, diesel engine (internal-combustion engine) is mainly used in the aspects such as automobile, generator set, and diesel engine of vehicle and generator set diesel engine have the former rotating speed of maintenance, and the unfixed feature of carrying capacity is arranged; As automobile (lorry) when keeping former rotating speed operation, have heavy duty, also unloaded, operation category of roads arranged, car loading automatic is different, during as grid power blackout, it is different keeping former rotating speed (during hot climate, when weather is got married) carrying capacity that diesel generating set is used in the hotel.The rotating speed of existing diesel engine (internal-combustion engine) is directly proportional to fuel consumption, discharge amount of exhaust gas.That is to say, existing diesel engine (internal-combustion engine) keeps former rotating speed, when carrying capacity reduces, can not reduce fuel consumption, can not reduce the shortcoming of discharge amount of exhaust gas; Also has diesel engine when low speed, the shortcoming of power difference very.
Summary of the invention
The present invention carries out rational improvement to existing diesel engine (internal-combustion engine), has overcome the shortcoming of background technique, and a kind of novel energy-conserving diesel engine (internal-combustion engine) is provided.The object of the present invention is achieved like this:
The solution of the present invention is to require according to diesel engine (internal-combustion engine) work done balance: stop the fuel delivery of a part of cylinder, make its cylinder there is no oil inflame and quit work, work done; Another part cylinder has oil inflame, continues work done, and (needing only) ignition interval does not change, and the rotating speed of diesel engine (internal-combustion engine) does not just change; Just reached the function that diesel engine (internal-combustion engine) keeps former rotating speed, the horsepower output of adjusting a wage scale, the fuel consumption of adjusting a wage scale, the discharge amount of exhaust gas of adjusting a wage scale.The present invention is by fuel tank, fall oil pipe, the parts such as fuel tap, high-pressure oil pipe, oil sprayer, cylinder cap, baroswitch, piston, cylinder sleeve, oil transfer pump, speed regulator or oil separator, oil inlet pipe, bent axle that fall and consist of.The present invention arranges oil pipe at the high-pressure oil pipe place of the cylinder of each cylinder or this machine some, and falling has down fuel tap on oil pipe; Baroswitch is arranged on cylinder cap.When diesel engine (internal-combustion engine) keeps former rotating speed, when carrying capacity reduces, (continue between the cylinder of work done according to internal-combustion engine work done balance, the igniting interval keeps that former time, piston promote that bent axle degree of turning equates, the stressed even weighing apparatus of bent axle) require: open in sequence the fuel tap that falls of some cylinders, make the fuel oil must not be by the oil sprayer of its cylinder, flow back to fuel tank through falling oil pipe, the cylinder that there is no oil inflame, just stop work done, baroswitch is opened, and is conducive to the motion of piston; The cylinder that obtains fuel oil continues, works stably, work done, and this makes diesel engine (internal-combustion engine) horsepower output of adjusting a wage scale, and reduces fuel consumption, reduces the function of discharge amount of exhaust gas.Keeping former rotating speed as a four-stroke six-cylinder diesel engine, when specified carrying capacity reduces 50%, according to the requirement of internal-combustion engine work done balance, open in certain sequence the fuel tap that falls of three cylinders, make fuel oil must not pass through the oil sprayer of its three cylinders, fuel oil warp fuel tap, the oil pipe that falls flows back to fuel tank, and three cylinders that can not get fuel oil quit work, work done; Another three cylinders obtain fuel oil with regard to continuation, smooth working, work done, and three cylinders igniting interval equates, the degree of turning that three cylinder works done promote bent axles equates.This four-stroke six-cylinder diesel engine has been converted into a four-stroke three-cylinder diesel and has moved work, work done stably in theory, make this four-stroke six-cylinder diesel engine reduce 50% specified fuel consumption, reduced 50% specified discharge amount of exhaust gas, can keep former rotating speed, reduce by 50% specified power stage.
Beneficial effect of the present invention be a kind ofly keep former rotating speed, the internal-combustion engine of can adjust a wage scale fuel consumption, horsepower output, rational in infrastructure.
