Three-stage VTEC is a multi-stage implementation of Honda's VTEC and VTEC-E (colloquially known as dual VTEC) technology, implemented in some of the company's D series engines from 1995 to the present day, allowing the engine to achieve both fuel efficiency and power. VTEC-E (for "Efficiency") is a form of VTEC that closes off one intake valve ...
A Honda K24A Engine with i-VTEC. VTEC (described as Variable Valve Timing & Lift Electronic Control, but stands for Valve Timing Electronically Controlled) 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.
The 1993 Prelude VTEC was the first Honda in the U.S. to use a new double overhead cam (DOHC) version of the VTEC variable valve timing system. ... Its 2.2-liter inline-four produced 190 ...
The H22 debuted in the U.S. in 1993 as the H22A1 for use in the Honda Prelude VTEC.Since then, versions of the H22 would become the Prelude's [2] signature high-performance engine worldwide until the end of Prelude [2] production in 2001.
In 1989, Honda released the VTEC system. [13] While the earlier Nissan NVCS alters the phasing of the camshaft, VTEC switches to a separate cam profile at high engine speeds to improve peak power. The first VTEC engine Honda produced was the B16A which was installed in the Integra, CRX, and Civic hatchback available in Japan and Europe ...
The D16Z6 engine in a 1994 Honda del Sol. VTEC Found in 1992-1995 Honda Civic Si (US) 1992–1995 Honda Civic EX, EX-V; 1992–1995 Honda Civic ESi (European Market) 1993–1995 Honda Del Sol Si (US) 1993–1996 Honda Del Sol ESi (European) Rod Length: 137 mm; Rod Ratio: 1.52~ Compression: 9.2:1; Power: 125 hp (93 kW; 127 PS) at 6600 rpm
In Honda's 2006 Civic Hybrid, the 1.3-liter i-VTEC engine uses a 3-stage valve design, an advancement from the 2005 i-VTEC technology. Aside from weight and friction reduction, the engine operates on either low-speed timing, high-output timing or 4-cylinder idling when the VCM system is engaged, each yielding better engine output upon varying ...
Honda expanded its well known Variable Valve Timing & Lift Electronic Control (VTEC) technology to marine engines in the 2000s. [2] VTEC varies the lift and duration of the intake valve opening, enhances performance at both low and high RPM. It provides a broad, flat torque curve and smooth power delivery. [2]
