Honda F20C engine

The Honda F20C engine is a four-stroke petrol internal combustion automotive engine, originally fitted to the Honda S2000.

History

The Honda F20C engine AP1, F20C is a 2.0-liter in-line 4-cylinder type VTEC naturally aspirated engine developing 240 hp (120 hp / l) at 8,300 rpm (Japan: 22.2 mkg at 7,500 rpm and 250 hp at 8,600 rpm, or 125 hp / l). The rev limit is at 9,000 rpm.

The specific power of 125 hp / l achieved by this engine was, until the appearance of the Ferrari 458 Italia, the absolute record for a naturally aspirated engine on a production car, it still remains the best naturally aspirated 4-cylinder in the world. The S2000 engine won the title of best engine in the world for 4 consecutive years: 2000, 2001, 2002 and 2003.

At the end of 2004, Honda developed a new version of the engine, the F22C1, for the North American market. The displacement has been increased to 2.2 litters and the red zone is reduced to 8,000 rpm. If the power is almost identical (240 hp), the torque increases and goes from 208 Nm to 220 Nm, which was the main reason for this engine. These are the AP2 versions of the S2000 that are equipped.

The F20C and F22C1 have a VTEC system for both the intake and exhaust camshaft two overhead cams with roller followers, a ladder-frame main bearing stiffener, Fibre-Reinforced Metal cylinder liner and molybdenum disulphide-coated pistons.
