The Honda P engine is an inline three-cylinder gasoline engine designed for use in Honda kei cars. The P engine was first used in the fourth generation Honda Life, as a successor to the Honda E07A engine. The P engine is produced in only one displacement variant: 658 cc, either naturally aspirated or turbocharged (the legislated maximum displacement of engines used in kei cars is 660 cc).

Design

The P-series engine was introduced in the fourth generation Honda Life in September, 2003. The engine uses a single overhead camshaft to drive two valves per cylinder (one intake, one exhaust, for a total of six). It also features the i-DSI ("intelligent dual and sequential ignition") spark ignition system, which utilizes two spark plugs per cylinder. The spark plugs fire sequentially, one after the other, in order to more completely burn the fuel charge for more power, lower fuel consumption and lower emissions. Fuel is delivered using Honda's PGM-FI electronic fuel injection system.

An unusual feature of this engine's design is that it does not have a separate exhaust manifold. Instead the exhaust gasses collect in the passages of the cylinder head itself and are fed directly into the catalytic converter. Honda claims this design helps to warm the catalyst quicker in order to more effectively filter out harmful emissions.^[1]
