Ethanol fuel engine

Abstract

The invention relates to the technical field of internal combustion engines and discloses an ethanol fuel engine. The ethanol fuel engine comprises an engine body, an air cylinder, an air cylinder cover assembly, an air inlet system, an air exhaust system, a piston, a front-end accessory system and an oil pressure guide rail, wherein the oil pressure guide rail comprises a fuel guide rail and electric heating oil-spraying nozzles, each electric heating oil-spraying nozzle comprises an oil-spraying control pin, a heating control pin, an electric heating pre-heating end, a heating resistor and a heat transfer core; the heating resistor is arranged in the electric heating pre-heating end and electrically connected with the heating control pin; a fuel channel is formed in the heat transfer core. Cold starting of the ethanol fuel engine can be realized through ethanol, and gasoline and ethanol in any ratio can be combusted.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to an ethanol fuel engine. Background technique [0002] Traditional vehicle engines are generally gasoline engines and diesel engines. With the increase of the number of automobiles in our country, the pollution caused by the exhaust of vehicle engines is becoming more and more serious. In 2000, my country stopped the production of leaded gasoline and began to carry out basic research on alternative fuels. As a preferred alternative fuel, ethanol began to be used in vehicle engines. [0003] However, since traditional automotive gasoline or diesel engines can only use a single fuel during design and production, even if they can be converted into alternative fuel engines such as ethanol engines in the later stage, the modified engine still needs to be assisted by gasoline when starting. Switch to ethanol fuel only after the oil temperature and other indicators a...

Problems solved by technology

[0003] However, since traditional automotive gasoline or diesel engines can only use a single fuel during design and production, even if they can be converted into alternative fuel engines such as ethanol engines in the later stage, the modified engine still needs to be assisted by gasoline when starting. After the oil temperature and other indicators are running normally, you can switch to ethanol fuel

Moreover, the ethanol content in usable ethanol gasoline is also limited to less than 10%. If the ethanol content exceeds 10%, there will be problems such as difficulty in starting the vehicle or a decrease in power performance, which makes the use of ethanol fuel inconvenient.
