How does the i-VTEC engine work?
The VTEC system essentially combines low-RPM fuel efficiency and stability with high-RPM performance. This allows more air and fuel to enter and burn, creating stronger torque and horsepower. In any engine, valve timing, duration and lift that optimize performance at low speeds are very different than high RPM needs.
What engines have i-VTEC?
i-VTEC. Honda i-VTEC (intelligent-VTEC) is a system that combines VTEC with Honda’s VTC (Variable Timing Control), a continuously variable camshaft phasing system used on the exhaust camshaft of DOHC VTEC engines. The technology first appeared on Honda’s K-series four-cylinder engine family in 2001.
What is Honda i-VTEC engine?
i-VTEC stands for Intelligent Variable Valve Timing and Lift Electronic Control, a system created by Honda to improve fuel consumption of Honda vehicles. The VTEC system uses two camshaft profiles and hydraulically selects between the two. Honda i-VTEC permits the engine to effectively have multiple camshafts.
What is SOHC i-VTEC engine?
SOHC – Single Over Head Cam Shaft a design in which one camshaft is placed within the cylinder head. VTEC stands for Variable Valve Timing and Lift Electronic Control and represents a variable valve control system developed by Japanese Honda for its gasoline engines.
What is Vtech in cars?
By Rick Popely. June 20, 2020. VTEC is an acronym for a variable valve-timing system used on Honda and Acura models since 1989. The full name is variable valve timing and lift electronic control, and the first U.S. model with VTEC was the 1991 Acura NSX.

How to test VTEC oil psi switch?
autiger. I’m having some issues at the moment.
How does a VTEC system work?
VTEC. As revs climb,the computer directs oil flow (A) through the rocker shaft.
How Honda VTEC works?
– Based on an electronic signal sent from your Honda ECU, there’s a solenoid that activates VTEC. Once the VTEC solenoid in your Honda is activated, it uses oil pressure to push an engaging pin through your valvetrain. This activates the larger lobe of your camshaft, which increases duration and extends lift of your valves.
