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.

Two versions of the Honda i-VTEC system can be found on a K-series engine, and both versions can come with variable timing control (VTC) on the intake cam. The VTEC system on engines like the K20A3 only operate on the intake cam; at low rpm only one intake valve is fully opened, the other opening just slightly to create a swirl effect in the ...
Two engine choices are offered, the 1.8-litre naturally aspirated with i-VTEC technology carried over from the previous generation model produces 141 hp (105 kW) and 174 N⋅m (128 lb⋅ft) of torque (E trim) and the new 1.5-litre VTEC Turbo produces 173 hp (129 kW) and 220 N⋅m (160 lb⋅ft) of torque, equipped with turbocharger (RS trim).
This first B series engine, marked the introduction of Honda's variable valve timing and electronic lift control technology . By providing two different camshaft profiles—one for fuel economy, one for performance, the VTEC engines set a high-revving, naturally aspirated precedent for future performance variants of the Honda Civic.
