How does VTEC work?
It stands for Variable Valve Timing & Lift Electronic Control. 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.
Is VTEC or VTEC better?
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. …
What is VTEC solenoid on Honda?
The VTEC solenoid actually allows oil to flow to the internal galleries of the overhead camshaft. This means that the housing of the solenoid is holding back full engine oil pressure. Then the oil escapes quickly from the engine at this point.
What is the difference between VTEC and non VTEC?
Difference Between VTEC and non-VTEC
- VTEC engines use two camshaft profiles while non-VTEC engines only use one.
- VTEC engines can have excellent performance at high and low speeds while non-VTEC engines can only be optimized for either.
- VTEC is only available on Hondas while non-VTEC are found on any car brand.
Which Hondas have VTEC?
Introduced as a DOHC (Dual overhead camshaft) system in Japan in the 1989 Honda Integra XSi which used the 160 bhp (120 kW) B16A engine. The same year, Europe saw the arrival of VTEC in the Honda Civic and Honda CRX 1.6i-VT, using a 150 bhp (110 kW) B16A1 variant.
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.
