Novel electronic control emission reducing and oil saving system device for vehicle

Abstract

The invention discloses a novel electronic control emission reducing and oil saving system device for a vehicle. The novel electronic control emission reducing and oil saving system device for the vehicle comprises two electronic control subsystems, one subsystem is an engine exhaust gas recirculation EGR electronic control subsystem, and the other subsystem is an engine crankcase exhaust gas filtration recombustion electronic control subsystem. The novel system device comprises main parts including a central controller ECU, a novel oil-gas separator, electromagnetic valves, an accelerator position sensor, a rotation speed sensor, a temperature sensor, an air compensating plate, an air filter and cooler and related pipelines. The tail gas nitric oxide emission load can be significantly reduced through the EGR electronic control subsystem, waste oil in exhaust gas volatilized from a crankcase can be effectively separated out through filtration of multiple layers of filter element partition plates of the novel oil-gas separator by means of the engine crankcase exhaust gas filtration recombustion electronic control subsystem, relatively clean air enters an engine to be combusted again, and emission of CH compounds in the exhaust gas is obviously reduced. Through combination of the engine EGR electronic control subsystem and the engine crankcase exhaust gas filtration recombustionelectronic control subsystem, vehicle exhaust gas emission is comprehensively and significantly improved, vehicle power is effectively improved, and the oil saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection of motor vehicles, in particular to a novel vehicle electronically controlled emission reduction and fuel saving system device. Background technique [0002] In the electronically controlled emission reduction and fuel saving system device in motor vehicles, the EGR subsystem is used, that is, the exhaust gas recirculation combustion system. The gas plate is input to the engine intake pipe port to the engine for secondary combustion, so as to improve the emission of the car, especially to significantly reduce the emission of nitrogen oxides. However, the EGR subsystem alone cannot improve CH compounds, another important parameter of exhaust emissions. If the air supply of the EGR subsystem is increased, the nitrogen oxide emissions will be significantly reduced, but the CH compounds emissions will not decrease but increase. Therefore, we must seek other solution...

However, relying on the EGR subsystem alone cannot improve CH compounds, another important parameter of exhaust emissions. If the air supply of the EGR subsystem is increased, the nitrogen oxide emissions will be significantly reduced, but the CH compounds emissions will not decrease but will increase.
