The Ecotec 2.4L engine is uses continuously variable valve timing to optimize performance, efficiency and emissions. It features durability and technology features familiar in premium V-type engines, including low-friction hydraulic roller-finger valve operation and an electronic throttle. A hydraulic tensioner keeps the timing chain adjusted for life, and extended-life spark plugs deliver 100,000 miles (160,000 km) of service.
Overhead cams are the most direct, efficient means of operating the valves, while four valves per cylinder increase airflow in and out of the engine. Continuously variable valve timing optimizes the engine's turbocharging system by adjusting valve timing at lower rpm for improved turbo response and greater torque delivery
Cam phasing allows an outstanding balance of smooth torque delivery over a broad rpm range, high specific output and good specific fuel consumption. Cam phasing also provides another effective tool for controlling exhaust emissions.
The Ecotec 2.4L camshafts feature 4X timing reluctors with digital sensors. This state-of-the-art control system allows the ECM to accurately measure and adjust valve timing, with consistent performance over the engine's anticipated useful life.
Consists of engine block, crankshaft, connecting rods, standard size pistons, piston rings, cylinder head assembly (including valve train components), lifters, camshaft, camshaft position actuator and position actuator solenoid valves, timing gears and chain, timing chain dampener, front cover, crankshaft balancer, spark plugs, oil pump, valve cover, oil pan.
