The Honda Accord F22B1 engine general information - is a part of Honda Accord repair manuals: Engines. The Honda Accord F22B1 engine is an in-line 4-cylinder SOHC design displacing 2,156 cm3 (131.5 cu-in). It is water cooled and equipped with a center plug type pent-roof combustion chamber.
It is specified to use unleaded fuel and uses a PGM-FI (Sequential Multiport Fuel Injection) system. This engine incorporates a mechanism called Honda Variable Valve Timing and Valve Lift Electronic Control (VTEC) System. The design of other engine models are basically the same as F22B1 engine except the displacements and VTEC system. This system allows the timing and lift of the intake valves to be changed simultaneously.

Features:
the cylinder head is made of aluminum alloy, a center plug type, pentroof-shaped combustion chamber is used, and the 4-valve system uses 2 intake valves and 2 exhaust valves; the camshaft and the valve train are driven by a timing belt, and the two balancer shafts are driven by a timing balancer belt; the cylinder block is made of aluminum alloy using cast iron sleeves; the crankshaft is made by forging, is supported at five points and has eight balancer weights; the balancer shafts employ a gear-type reverse mechanism to reduce secondary engine vibration; the intake manifold is made of aluminum alloy; the electronic fuel injection system is a sequential multiport type. It injects fuel into all four cylinders. The throttle body is a one-barrel, side-draft type; the ignition system is a fully-transistorized, contactless type. The spark advance is electronic; the air cleaner is equipped with a resonator; the radiator is a corrugated type, and the cooling fan is electrically powered.
