For example, electromechanical actuators could replace standard camshafts for controlling valve opening. |
The 16-valve has twin, chain-driven, overhead camshafts and hydraulic tappets, while the 8-valve format uses a single camshaft. |
The engines had twin overhead camshafts which were gear driven via a train of gears coming from the rear of the crankshaft. |
For the engine, there are camshafts, crankshafts, valves, connecting rods, and balance shafts. |
Both engines incorporate dual-overhead camshafts and four valves per cylinder. |
Stacked one above the other, the camshafts operate three valves per cylinder via short pushrods. |
