The K series Honda engines are all equipped with DOHC (an acronym for double overhead camshafts) camshafts and valvetrains with Honda’s i-VTEC variable valve timing control. The popularity of these engines makes this a long post. Essentially, I have used some Wiki information to form a list of all of the K-series Honda engines. Much of the unnecessary information I deleted, as it may be confusing.

Honda made this engine a big improvement over its older 4-cylinder engines by including friction-reducing technologies to reduce internal friction and power-loss.

The K-series motors all use DI, or distributorless ignition. It uses a coil on plug system, in which each spark plug has its own coil atop it. This allows the ECU to send the spark exactly when it wants it, and removes the need for spark plug wires.

This is a complete listing of Honda’s K Series Engines with technical specs and the model cars that you can find them in….

Honda K engines

The K series engines are equipped with DOHC valvetrains and use roller rockers to reduce friction. The engines use a coil on plug, distributorless ignition system with a coil for each spark plug. This system eliminates the need for spark plug wires as well as the problems associated with them. It also allows the ECU to precisely control the ignition timing based on various sensor inputs. The cylinders have cast iron sleeves similar to the B-series engines, as opposed to the FRM cylinders found in the H-series.
