Abstract
A valve train for a twin cam engine has three valves per cylinder, including a pair of side-by-side intake valves and a single exhaust valve on an opposite, exhaust side of the combustion chamber. Dual camshafts in a V-type engine separately drive the intake and exhaust cams through a single dual arm intake rocker arm and a single exhaust rocker arm per cylinder, which provides much improved inlet port airflow for improved specific output compared to a single inlet valve engine. The single exhaust valve provides better catalytic converter performance due to lower exhaust heat loss than in four-valve engines of the same output capability. The intake and exhaust valve trains provide coplanar action of the push rods, rocker arms and valve stem axes, yielding an efficient and simplified valve train with a high flow combustion chamber. Additional features and advantages are disclosed.
