Automobile power regulator

Abstract

The automobile power regulator includes one first gas pipeline connected between the air intake boosting pipe of the engine and the boosting pipe of the high pressure oil pump, and features the first gas pipeline with boosting gas pressure controlling solenoid valve communicated with the pipeline. The present invention can regulate the output power of the engine based on practical requirement, increase the output power of engine, save fuel, reduce waste gas exhaust and reduce air pollution, has reasonable structure and compact arrangement, and is especially suitable for automobile with diesel engine adopting turbocharger.

Description

technical field [0001] The invention relates to a power regulator, in particular to a power regulator for turbocharged diesel engine vehicles. Background technique [0002] As we all know, the gas distribution device of the existing diesel engine uses a turbocharger, and its engine intake booster pipe is directly connected with the high-pressure oil pump booster tube. During the running of the car, the compressed gas in the engine intake booster tube is boosted by the high-pressure oil pump. The pipeline boosts the oil pump, and the higher the pressure of the boosted gas, the stronger the boost boost of the high-pressure oil pump, and the corresponding increase in the fuel injection volume, which is conducive to making the engine output faster when the car goes uphill and under heavy loads. Good power, but when the vehicle is driving on a flat road with a light load, the output power of the engine will be much greater than the power required by the load, resulting in unneces...

[0002] As we all know, the gas distribution device of the existing diesel engine uses a turbocharger, and its engine intake booster pipe is directly connected with the high-pressure oil pump booster tube. During the running of the car, the compressed gas in the engine intake booster tube is boosted by the high-pressure oil pump. The pipeline boosts the oil pump, and the higher the pressure of the boosted gas, the stronger the boost boost of the high-pressure oil pump, and the corresponding increase in the fuel injection volume, which is conducive to making the engine output faster when the car goes uphill and under heavy loads. Good power, but when the vehicle is driving on a flat road with a light load, the output power of the engine will be much greater than the power required by the load, resulting in unnecessary fuel consumption and a potential safety hazard; that is to say , During the operation of the car, there is an imbalance between the engine output power and the car load, the gas volume of the pressurized gas entering the high-pressure oil pump is uncontrollable, and the oil pressure and fuel supply of the high-pressure oil pump of the engine cannot be adjusted according to the car load and driving road conditions , so that the engine outputs the required corresponding power

[0003] When the car is running at a low speed, the engine boost gas cannot better boost the high-pressure oil pump, the oil pressure of the oil pump is weak, and the fuel injection volume is reduced accordingly, which will cause the engine to Insufficient oil pressure, insufficient air intake, sharp drop in power, forced to downshift, change the transmission ratio, prolong the driving time of the vehicle and the running time of the engine, increase the number of operations, and correspondingly increase the number of oil supply, unnecessary Fuel consumption doubles
