What is VTECH and Why is it Important?Jul 14th, 2016
If you drive a newer Honda vehicle, chances are it’s equipped with some version of VTEC. In fact, some Honda models started using variable valve timing starting in the 80’s. That’s what VTEC is – Variable Valve Timing and Lift Electronic Control. Those are just fancy words to say that your engine’s valves can open and close at different times and at varying heights, all controlled by the engine management system.
What does VTEC do?
Variable valve timing advances or retards the movement of your engine’s valves depending on what the engine requires. If you’re under hard acceleration, it could open the intake valves slightly ahead of time to allow more air into the combustion chamber for the ignition stroke.
How high the valves lift is also moderated by the engine computer, activating a solenoid to engage higher lift camshaft lobes inside the engine to achieve maximum performance and efficiency.
Another benefit of VTEC – a cleaner burning engine. The exhaust valve can close slightly earlier than usual to allow some exhaust gas in the cylinder while fresh air is drawn in. It helps prevent harmful NOx and burns cleaner, operating much like the EGR system on your car.
Why is VTEC important?
With VTEC, you get the best of both worlds. Your Honda gets the best performance possible, no matter how you drive through intelligent variable valve timing and precision valve lift height control. It means the same engine size can produce more power than ever. Better yet, it can do so without harming your fuel efficiency. In fact, VTEC improves your fuel efficiency significantly!
VTEC-E and i-VTEC both focus on improving fuel efficiency. They use variable timing control (VTC) through a camshaft phase adjustment. It optimizes torque when accelerating while providing superb fuel economy, all by adjusting the engine timing.
VTEC Turbo, the most recent VTEC development, takes it one step further with direct fuel injection and a turbocharger. Now your Honda can get surprising power from a smaller engine while still maintaining excellent fuel efficiency!
There are. All the different variations of VTEC, whether i-VTEC, VTEC-E or VTEC Turbo, function relatively similarly and serve the same purpose – to improve power and fuel efficiency. Some Honda motorcycles even have VTEC technology!
