Engine for 4G18CVVT UMC
The 4G18CVVT UMC engine is a continuously variable valve timing mechanism. Variable valve timing technology, by opening the intake valve in advance and closing the exhaust valve later, increases the intake air charge, increases the charge coefficient, and further improves the engine’s torque and power, which can increase the engine’s low-speed torque. , it does not help much to increase torque at high speeds.
