Engine Honda R18A under the hood

Engine Honda R18A

In 2006, a new R18 engine was used on the Civic 8 from Honda, which replaced the D17 engine, and on this “D” -series were no longer installed on Honda cars. The timing for the new engine is driven by a chain, the head has not been changed – all the same 16 valves and 1 camshaft, but the intelligent iVTEC system and dual-mode intake have already been added. The motor does not have hydraulic pushers, so the valves need to be adjusted every 40,000 km. A year later, Honda engineers, based on this engine, released a 2-liter R20A, which was installed on cars higher than the Civic class.
