twin-cam
Two-camshaft engine design
Twin-cam describes an engine with two camshafts, typically one controlling intake valves and one controlling exhaust valves.
This design allows more precise valve timing and higher engine speeds than single-cam configurations.
The term appears mainly in automotive contexts: a twin-cam four-cylinder, the twin-cam engine delivers better performance at high RPMs.
