A Honda K24A Engine with i-VTEC. VTEC (described as Variable Valve Timing & Lift Electronic Control, but stands for Valve Timing Electronically Controlled) is a 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.
It is fuel injected, has an aluminum-alloy cylinder block and cylinder head, is a SOHC 16-valve design (four valves per cylinder) and utilizes Honda's i-VTEC system. The R series engine has a compression ratio of 10.5:1, features a " drive by wire " throttle system which is computer controlled to reduce pumping losses and create a smooth torque ...
Three-stage VTEC is a multi-stage implementation of Honda's VTEC and VTEC-E (colloquially known as dual VTEC) technology, implemented in some of the company's D series engines from 1995 to the present day, allowing the engine to achieve both fuel efficiency and power. VTEC-E (for "Efficiency") is a form of VTEC that closes off one intake valve ...
The F20C was designed with high engine speed capability in mind, for increased power output; the rev limit is 9,000 rpm, with VTEC engagement at 6,000 rpm. Its relatively long stroke of 84 mm results in a mean piston speed of 4,965 ft/m, or 25.2 m/s, which was higher than any other production car to date. [ 4 ]
