From 1991 to 2018, the company’s factories produced the 0.8-liter Daewoo F8CV engine, which was used in many low-cost vehicles but is most recognized as the primary Daewoo Matiz engine. This power unit, which is referred to as the A08S3 on Chevrolet models, was based on the Suzuki F8B.
The CV series also includes: F10CV.

Disadvantages of the Daewoo F8CV engine
The engine had a rather erratic ignition distributor until 2008.
Other electrical systems are also thought to be unreliable, particularly the throttle position sensor, which frequently malfunctions.
Fuel injectors clog and candles quickly burn out due to poor gasoline.
The valves bend when the timing belt breaks, which has a modest resource of 50,000 kilometers.
Additionally, valve clearances must be periodically adjusted and seals frequently leak.
