introduction：A gasoline engine that forms a combustible mixture of gasoline and air by injecting gasoline。Compared to a gasoline engine using a carburetor﹐Its advantages are﹕Because theres no carburetor﹐Low intake resistance﹐Thus more air intake﹔Fuel distribution of each cylinder is more uniform﹐And it can control the injection amount and intake volume respectively according to the engine working condition﹐A mixture that precisely supplies the engine with the best air-fuel ratio﹐The compression ratio can also be appropriately increased。The power of gasoline injection engines﹑Both economy and exhaust performance are better than gasoline engines using carburetors。But its structure is complicated﹐High cost﹐Less reliable﹐So its only used in some cars。 Gasoline injection
