Problems solved by technology

The current diesel engine has to sacrifice some thermal efficiency in order to reduce the emission of nitrogen oxides, which in turn leads to an increase in fuel consumption. Therefore, for the current diesel engine technology, fuel saving and reduction of nitrogen oxide emissions have formed a pair that is not easy to solve. contradiction
[0003] The current gasoline engine has low thermal efficiency, high fuel consumption, and high carbon monoxide emissions. The main reason is that it cannot adopt high compression ratio and large e

Abstract

The invention relates to a clean multi-fuel internal combustion engine, and belongs to the technical field of internal combustion engines. The internal combustion engine comprises a cylinder, a piston, a connecting rod, a crank shaft, an air inlet channel, an intake valve, an exhaust channel, an exhaust valve, a fuel injector or an igniter and an injector, the injector of the internal combustion engine is arranged on a side wall of the air inlet channel, and is communicated with the air inlet channel. In the clean multi-fuel internal combustion engine, one or more injectors are mounted on theair inlet channel of the internal combustion engine, and water, methanol or ethanol is injected into the air inlet channel by the injector according to different purposes, thus being capable of greatly reducing harmful gas emission of diesel engines, using a plurality of fuels, improving thermal efficiency, and obtaining fuel saving effect. Gasoline engines can employ more excess air and higher compression ratio.

Description

technical field [0001] The invention relates to a clean multi-fuel internal combustion engine, which belongs to the technical field of internal combustion engines. Background technique [0002] In the combustion exhaust gas of diesel engines, the main harmful gas is nitrogen oxides, and nitrogen oxides are caused by diesel engines adopting high boost to save fuel, increasing fuel injection pressure and fuel injection speed, so that diesel fuel burns rapidly in the cylinder and the instantaneous temperature is too high. due to high. The current diesel engine has to sacrifice some thermal efficiency in order to reduce the emission of nitrogen oxides, which in turn leads to an increase in fuel consumption. Therefore, for the current diesel engine technology, fuel saving and reduction of nitrogen oxide emissions have formed a pair that is not easy to solve. contradiction. [0003] The main reason for the low thermal efficiency, high fuel consumption and high carbon monoxide em...
