Honda K-series Engine Specs Information

The Honda K series car engine is a four-cylinder four-stroke engine introduced in 2001. The K series engines are equipped with DOHC valvetrains and use roller rockers to reduce friction. The engines use a coil-on-plug, distributor-less ignition system with a coil for each spark plug. This system forgoes the use of a conventional distributor-based ignition timing system in favor of a computer-controlled system that allows the ECU to control ignition timings based on various sensor inputs. The cylinders have cast iron sleeves similar to the B-series & F-series engines, as opposed to the FRM cylinders found in the H-series and newer F series engines found only in the Honda S2000.

 

Similar to B series, K-Series car engine has two short blocks with the same design; the only difference between them being the deck height. K20 uses the short block with a deck height of 212mm where K23 and K24 block has a deck height of 231.5mm.

 

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 combustion chamber for improved fuel atomization. At high rpm, both intake valves open fully to improve engine breathing. In engines such as the K20A2 found in the Acura RSX Type-S, the VTEC system operates on both the intake and exhaust valves, allowing both to benefit from multiple cam profiles.

This section previously inaccurately suggested that the 2016-2017+ Acura ILX engine K24V7 and the K24W7 of the Acura TLX are the same engine, and although they may be very closely related, even sharing identical internal architecture and components, they actually are different engines with different Honda internal engine code designations. This may be strictly due to different transmissions, as the 2016-2017+ ILX uses its own specific 8-speed dual-clutch auto with a torque converter, as well as different exhaust, intake, and accessory packaging due to their differing chassis [the ILX sharing its basic architecture with the 2013 - 2016 generation Civic].
