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.
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 ...
Variable Cylinder Management (VCM) is Honda's term for its variable displacement technology, which saves fuel by using the i-VTEC system to disable one bank of cylinders during specific driving conditions—for example, highway driving. The second version of VCM (VCM-2) took this a step further, allowing the engine to go from 6 cylinders, down ...
It is fuel injected, has an aluminum-alloy cylinder block and cylinder head, is a SOHC 16-valve design (four valves per cylinder) and utilizes Honda's i-VTEC system. The R series engine has a compression ratio of 10.5:1, features a " drive by wire " throttle system which is computer controlled to reduce pumping losses and create a smooth torque ...
NVTCS is hydraulically actuated similar to Honda's VTEC system, but adjusts a different aspect of the valve train, so it is more like the I part of I-VTEC. [ 2 ] [ 3 ] NVTCS equipped Nissan engines do not have as high of engine speeds as VTEC equipped engines so NVTCS is simpler, quieter, and requires no special maintenance.

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 ...
