VTEC – Honda Engines Redefine the Landscape
Honda has always been known for its advanced technology off the engine. VTEC (Variable Valve Timing and Lift Electronic Control), showed that it is different, and you know that Honda makes a decisive advantage over their competitors again. Invented at the beginning of the year 1980 in research and development engineer Ikuo Kajitani, what we now know as the VTEC grew from the revolution modulation valve control system implemented in 1983 in the Honda CBR400. While other manufacturers produced their own versions, Honda was the real pioneer and develop technology and leads to large-scale production.
To understand innovation, VTEC, it is necessary to appreciate the subtlety of the timing of the engine intake and exhaust valves to move the camshaft lobes. Three elements are involved and shape of the lobes of the camshaft determines each. The first element is the time angle measurements, when the valve is opened or closed in relation to the position of the piston means. Lift the distance the valve lifts the valve seat. Duration refers to how many degrees of crankshaft rotation, the valve remained open. Due to differences in behavior in a mixture of fuel and air before and after the two towers burning high and low, there is also a big difference in engine power. Parameters for optimal timing at high engine speeds and a lot of power, but give a very rough engine performance at low speeds (where most cars spend their time). Before setting the time for the spectrum at low engine speeds and a kitten, but engine power very soon. Ideally, the engine has fully variable timing, setup time, time and distance, so that the valves would always be exactly the right place regardless of the opening of the motor speed. VTEC is designed to marry the idea of ??high output power from the engine speed and stability at low speeds.
