What does VTEC engine do to your car?
The VTEC system essentially combines low-RPM fuel efficiency and stability with high-RPM performance. And the transition occurs seamlessly, allowing for smooth performance across the entire powerband. The switching operation between the two cam lobes is controlled by the engine computer.
Is VTEC better than v6?
Yes, Honda VTEC engines are VERY good because they’re engines that run more efficiently than engines without variable valve timing, literally have two personalities in one engine, very reliable mechanical system, and they have a unparalleled high horsepower for a naturally aspirated engine with just 4 and 6 cylinders.
Does VTEC increase HP?
VTEC is a type of variable valve-timing system developed and used by Honda. At higher engine speeds, the cam profile allows greater valve lift, which allows more air into the cylinder. This helps generate more horsepower.
What does VTEC stand for in automotive category?
For other uses, see VTEC (disambiguation). VTEC (Variable Valve Timing & Lift Electronic Control) 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.
What does the VTEC system in a Honda engine do?
Image Gallery: Engines The VTEC system in Honda engines allows the engine to have multiple camshafts. See more car engine pictures . If you have read How Car Engines Work, you know about the valves that let air into the engine and let exhaust out of the engine. You also know about the camshaft that controls the valves.
What kind of valve timing does a VTEC engine use?
The VTEC system provides the engine with valve timing optimized for both low and high RPM operations. In basic form, the single cam lobe and follower/rocker arm of a conventional engine is replaced with a locking multi-part rocker arm and two cam profiles: one optimized for low-RPM stability and fuel efficiency,…
When did the DOHC VTEC engine come out?
The DOHC VTEC improved the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM. Since its first introduction in 1989, the VTEC technology has completely changed the way the world looked at engines.
