    The 4G18CVVT engine is primarily used in several models of Geely cars, including 

the Emgrand GL Vision, and EC7. This engine is independently developed by Geely 

and is a 1.8L displacement engine that adopts CVVT technology, marking it the first 

domestically developed 1.8L CVVT engine in China. 

Features of the 4G18CVVT engine include: 

    Advanced Technology: It variable valve timing technology (CVVT), which enhances

fuel economy and combustion efficiency. High Stability: Although it doesn't excel in 

power output, it offers high technical stability, providing users with a hassle-free 

experience. Wide Application: This engine is widely used in various Geely models, 

including the Borui, Boyue, andgrand. Additionally, other Geely engine models such 

as the JLC4G18 and JLE-4G18TDC are also used in models, showcasing Geely's

continuous innovation and progress in engine technology.
