Method and device for controlling output power of energy-saving and high-efficiency engine of automobile

Abstract

The invention relates to a method and device for controlling the output power of an energy-saving and high-efficiency engine of an automobile, which comprises an air supply device for supplying the air to a combustion chamber of an internal combustion engine, a control device, a braking inductor and an accelerator pedal inductor, wherein the air supply device comprises a main pipe communicated with the combustion chamber of the internal combustion engine, a cold air branch pipe, a hot air branch pipe for supplying hot air, an electric valve and a filter; one end of the cold air branch pipe and one end of the hot air branch pipe are connected with the main pipe through the electric valve, and the other end of the cold air branch pipe and the other end of the hot air branch pipe are connected with the filter; the control electric signal output of the control device is connected with the electric signal input of the electric valve; and the electric signal output of the braking inductor and the electric signal output of the accelerator pedal inductor are respectively connected with the control electric signal input of the control device. Compared with the prior art, the invention has the advantage that the energy consumption can be reduced when the automobile does not need to do work.

Description

technical field [0001] The invention relates to a method and a device for controlling output power of an automobile engine. Background technique [0002] The output power of the internal combustion engine is generally controlled by the intake valve of the internal combustion engine, which is controlled by adjusting the intake air volume and matching the fuel injection volume. The limit output power of a conventional internal combustion engine is limited to the capacity of the combustion chamber. The use of turbocharging to increase the limit output power of the internal combustion engine is determined by the capacity of the combustion chamber and the density of the intake air. Regardless of the method, the power output by the cylinder combustion once is basically the same. When the car is running, there is no need for engine output power for a long time (such as when braking and waiting for traffic lights). However, during the above-mentioned period, the combustion chamber...

Problems solved by technology

When the car is running, there is no need for engine output power for a long time (such as when braking and waiting for traffic lights). However, during the above-mentioned period, the combustion chamber of the engine still outputs a constant power once, and these output powers are not any effect, thus wasting energy in vain
