The Honda

Honda

is a Japanese public multinational corporation primarily known as a manufacturer of automobiles and motorcycles.Honda has been the world's largest motorcycle manufacturer since 1959, as well as the world's largest manufacturer of internal combustion engines measured by volume, producing more than...

 K series 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, distributorless 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 one that allows the ECU to control ignition timings based on various sensor inputs. The cylinders have cast iron sleeves similar to the B-series

Honda B engine

The Honda B-series are inline-4 DOHC automotive engines. They were made in 1.6, 1.7, 1.8, and 2.0 liter variants, with and without VTEC . Later models have minor upgrades including modifications to the intake valves and ports and piston tops, along with individual cylinder oil injectors...

Honda F engine

The Honda F-Series engine was Honda's "big block" SOHC inline four, though lower production DOHC versions of the F-series were built. It features an aluminum open deck cast iron sleeved block and aluminum/magnesium cylinder head...

Honda H engine

The Honda H engine was Honda's high-performance engine family from the 1990s and early 2000s. It is largely derived from the Honda F engine with which it shares many design features. Like Honda's other 4-cylinder families of the 80s and 90s, it was replaced by the Honda K engine...

.

Two versions of Honda's i-VTEC system can be found on K series engines; variable timing control (VTC) can be found on the intake cam of both versions. 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

Acura RSX

The Honda Integra DC5 is a Japanese performance sports car, which was also known as the Acura RSX in North America . It is available in base and "Type-S" models in North America, and a "Integra iS / Integra Type S" and "Type R" version sold in Japan and Oceania...

 Type-S, the VTEC system operates on both the intake and exhaust valves, allowing both to benefit from multiple cam profiles.
