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.

Honda wasn't the first or last to do variable valve timing and lift, but no one did it with such style.
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 ...
The Honda R engine is an inline-four engine launched in 2006 for the Honda Civic (non-Si). 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.
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 valve timing (VVT) is the process of altering the timing of a valve lift event in an internal combustion engine, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems.
