VTEC: History, Technology & Measurement

Variable Valve Timing & Lift Electronic Control (VTEC) is a valve system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high rpm, and lower fuel consumption at low rpm. VTEC uses two (or occasionally three) camshaft profiles and hydraulically selects between…
