What does i-VTEC mean on Honda?
Variable Valve Timing & Lift Electronic Control
The VTEC (Variable Valve Timing & Lift Electronic Control) system uses separate camshaft profiles for low and high-end performance, and the engine computer selects between profiles. The VTEC system essentially combines low-RPM fuel efficiency and stability with high-RPM performance.
Is i-VTEC better than VTEC?
Intelligent Variable Timing (and lift) Electronically Controlled (iVTEC), is a system that combines VTEC and VTC into one unit. The VTEC part of the system allows valve overlap to be adjusted at any moment, resulting in much greater efficiency and slightly better performance. …
Is i-VTEC the same as 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. Both engine load and RPM affect VTEC.
Are Honda VTEC engines good?
Honda claims that there has never been a warranty claim against their VTEC systems – as in, the solenoids and variable valve/timing system is quite reliable. This isn’t at all to say that these engines don’t fail – of course they do – however they have a very good track record for reliability if maintained correctly.
At what RPM does i-VTEC kick in?
It depends on the engine. Most Hondas had vtec crossover in the low to mid 5000rpm range. You had 2 camshaft profiles, 1 optimized for low-mid rpm driveability and fuel economy and another for mid-high rpm power.
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.
How does Honda VTEC work?
VTEC (which stands for Variable Valve Timing and Lift Electronic Control) is an electronic and mechanical system in some Honda engines that allows the engine to effectively have multiple camshafts. As the engine moves into different rpm ranges, the engine’s computer can activate alternate lobes on the camshaft and change the cam’s timing.
What is an i-VTEC in a Honda?
VTEC is a timing system designed by Honda Motor Corporation, which is used on a variety of Honda and Acura models in every major automotive market. VTEC stands for Variable Valve Timing and Lift Electronic Control. The system was upgraded to i-VTEC in the early 2000s, which added intake camshaft timing adjustment.
What is a VTEC engine?
VTEC is an acronym for Variable valve Timing and lift Electronic Control. It is a mechanism for optimizing air/fuel mixture flow through the engine. An internal combustion engine converts the chemical energy stored in fuel into thermal energy.
What is i VTEC?
Actually I-VTEC stand for intelligent variable valve timing and lift electronic control. This technology is introduce by one of the well known car maker HONDA. i-VTEC regulates the opening of air-fuel intake valves and exhaust valves in accordance with engine speeds.
