The VTEC [V-Tech], the world's first variable valve timing and lift mechanism developed by Honda. At present, it has become so popular that it is also used in mini vehicles, and is used not only in cars but also in motorcycles and outboard motors.
The second-generation Integra is the first to use an engine that uses the VTEC mechanism, which is synonymous with Honda's technology.
が Although this second-generation integra, the catch phrase of the “bracketed integra” and the use of Michael J. Fox as the image character attracted attention, the focus of the topic is still the VTEC engine.
VTEC is a low-speed and high-speed cam piece with different profiles on the camshaft. The cam piece is switched according to the engine speed to change the valve timing [open / close timing] and lift [opening height]. To allow more air to be taken into the combustion chamber.
The B16A type, which adopts this revolutionary mechanism, achieves 160ps / 7600rpm at 1.6L without sacrificing the low and medium speed range.
It achieved a high specification of "liter 100ps", which was considered difficult with technology at the time.
