Main  features:

Dual VVT (Variable Valve Timing) on both intake and exhaust sides: Improves the efficiency of air intake and exhaust. 

Electronically variable displacement oil pump: Automatically adjusts the oil supply based on engine load and speed. 

Low inertia exhaust turbine: Reduces turbine lag and enhances low-speed torque output.

GCCS (Gasoline Combustion Control System) technology: Improves combustion efficiency and reduces emissions.


The 4A15 engine is widely used in the Trumpchi GM6 and GS5 models.
