Water injection system for internal combustion engine

Abstract

The invention relates to a inspiratory tube arranged in inspiratory apparatus of internal-combustion engine, water injection system for internal combustion engine injects particulate water according the state of motorcar to make internal combustion engine work in optimized efficiency. The system recieves detecting speed, according detecting signal and speed detecting sensor output reciprocal pulse, a inspiratory tube arranged in inspiratory apparatus, humidity detecting sensor for detecting humidity, water level detecting sensor for detecting level and temperature of water tank storing water which injected into the inspiratory tube, output singal of water temperature detecting sensor, thereby spray water amount of internal-combustion engine is controled, wherein, the system also including detecting sensor for receiving speed, humidity detecting sensor, water level detecting sensor, output singal of water temperature detecting sensor, end door outputing to spray apparatus; rotate speed detecting apparatus for detecting rotate speed of internal-combustion engine; storing apparatus outputs ''enable'' signal only when rotate speed detected by rotate speed detecting apparatus higher than the given speed.

Description

【Technical field】 [0001] The present invention relates to an internal combustion engine water spray system, in particular to an internal combustion engine water spray system which is arranged on an air intake pipe of an internal combustion engine air intake device and sprays water in a particle state according to the state of the vehicle to make the internal combustion engine work with optimal efficiency. 【Background technique】 [0002] The air-fuel mixture combusted in the cylinder of the internal combustion engine is an appropriate mixture of air and fuel, and the mixing ratio of such air-fuel mixture is variable according to the operating state of the internal combustion engine. That is, in order to obtain the maximum output power of the internal combustion engine, it is necessary to reduce the air ratio to generate a high-concentration air-fuel mixture and supply it to the cylinder, but to save fuel, it is necessary to increase the air ratio to generate a lean air-air mix...

Problems solved by technology

[0005] However, after repeated experiments, it has been found that the above-mentioned internal combustion engine air intake device cannot achieve complete combustion of the internal combustion engine and maximum engine output power only by supplying water temperature or vehicle running speed, especially for low-speed engines, there is a problem of reduced engine output power on the contrary.
