Problems solved by technology

The former compressor is driven by exhaust gas energy: the compressor cannot rapidly increase or decrease the speed correspondingly when stepping on or lifting the accelerator pedal quickly; it is difficult to use a computer to accurately control the boost pressure in time, mainly relying on the ignition system to control knocking alone
The latter compressor is driven by the crankshaft through the transmission mechanism: the transmission ratio is fixed, and it is difficult to meet the requirements of the engine at high speed and low speed; the electromagnetic clutch only has two working states of "off" and "on", and it is difficult to use a computer to accurately control the boost pressure in time
The existing supercharging technology is limited by the driving mode of the compressor, and cannot be improved to meet the needs of gasoline cars.
The voltage of the car is increased from 14v to 42v, which provides the possibility to use the electric motor to drive the compressor, but its research and development is still blank

Embodiment Construction

[0014] The specific embodiment of the present invention is described further below:

[0015] The compressor is a centrifugal or volumetric compressor whose parameters such as pressure ratio and flow rate are matched with the engine boosting scheme; its external dimensions and connection positions meet the overall layout of the engine compartment and the needs for assembly and installation of the motor. The driving motor is a 42V DC motor, whose parameters such as speed and torque match the needs of driving the compressor; its external dimensions and connection position meet the overall layout of the engine compartment and the needs of assembling with the compressor. After the compressor and the electric motor are assembled, install them at appropriate positions in the engine compartment. The air inlet of the compressor is connected to the engine air filter through a rubber hose, and the air outlet is connected to the engine air flow meter through a rubber hose. The "positive po...

Abstract

The invention is mainly composed of compressor, driving electric machine, power unit, relay, control computer, switch board, display board, car speed sensor, grade sensor, air throttle sensor, altitude sensor, engine speed sensor, air inlet manifold branch vacuum sensor, knocking sensor, water temperature sensor, air inlet temperature sensor, air outlet temperature sensor and oxygen sensor. Its compressor is driven by the motor controlled by the computer, and it can actively, properly and quickly increase and reduce pressure, accurately control the knocking together with the igniting system, thus further heightening the power performance of gasoline-driven saloon car, fuel economic property and reducing waste gas discharge.

Description

technical field [0001] The invention relates to the air intake supercharging technology of an automobile internal combustion engine, and is suitable for a gasoline car adopting a 42v power supply system. Background technique [0002] Existing supercharging technologies mainly contain exhaust gas turbo (rotary) supercharging and mechanical supercharging. The former compressor is driven by exhaust gas energy: when the accelerator pedal is stepped on or lifted suddenly, the compressor cannot increase or decrease the speed correspondingly; it is difficult to use a computer to accurately control the boost pressure in time, and the knock is mainly controlled by the ignition system alone. The latter compressor is driven by the crankshaft through the transmission mechanism: the transmission ratio is fixed, and it is difficult to meet the requirements of the engine at high speed and low speed; the electromagnetic clutch only has two working states of "off" and "on", and it is difficu...
