VTEC
Sign in to savethumb|A Honda K24A Engine with i-VTEC right|thumb|VTEC engaging in the F23A7 Inline-four 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 profiles. It was invented by Honda engineer Ikuo Kajitani. It is distinctly different from standard VVT (variable valve timing) systems which change only the valve
