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.
