Introduction 

 

CAC478, CAC480 series vehicle gasoline engines, which are the products introduced from Ford 
(Britain) corporation CVH production line, are made by Anhui Chery automobile Corp. Products 
are made up of carburetor type, single-point electric control fuel injection type and electric 
control fuel injection type, which may meet the requirements for different performance and 
emission. 

 

Single-point electric control fuel injection system and multipoint electric control fuel injection 
system of the above engines are developed though the joint effort with Italy M & M Corp. 

 

With advanced product performance, reliable structure，CAC478、CAC480 series automobile 
gasoline engines may be applied for both car and light-duty vehicles. 
 
Specifications, covering major parameters, structural features, assembly and adjustment, 
common operation repair and maintenance, trouble shooting for CAC478, CAC480 carburetor 
and single-point electric control fuel injection engine, may be referred by mechanic, driver, 
technologist and management section.
