What does VTEC mean on a car?
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.
What makes a VTEC engine different?
VTEC is a type of variable valve-timing system developed and used by Honda. Like most other variable-valve timing systems, VTEC varies oil pressure to shift between different cam profiles. At higher engine speeds, the cam profile allows greater valve lift, which allows more air into the cylinder.
Are VTEC engines fuel efficient?
The VTEC TURBO engine is fuel efficient under any condition: from city driving with frequent stopping and starting, to highway driving.
How is a VTEC engine different from a VVT engine?
The VTEC system uses two camshaft profiles and hydraulically selects between profiles. It was invented by Honda engineer Ikuo Kajitani. It is distinctly different from standard VVT ( variable valve timing) which advances the valve timing only and does not change the camshaft profile or valve lift in any way.
What does VTEC stand for in Honda car?
by Sameca Pandova. 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.
When did the Honda V-TEC engine come out?
In the mid eighties, Honda developed the V-TEC engine which can switch seamlessly between low-rev and hi-rev camshaft profiles, allowing for smooth operation without sacrificing hi-rev performance. , A mechanical engineer who wants to study life science !
How does the Honda VTEC engine timing system work?
A third option is to change the cam timing profile, of which Honda VTEC was the first successful commercial design for altering the profile in real-time. The VTEC system provides the engine with valve timing optimized for both low and high RPM operations.
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.
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 a VTEC-E engine?
What is VTEC-E engine? Variable valve Timing and lift Electronic Control for Efficiency. This system isn’t really VTEC as we know it. At low RPM, the VTEC-E mechanism effectively forces the engine to operate as a 12-valve engine – one of the intake valves does not open fully, thus decreasing fuel consumption.
