Honda F Engine - Wikipedia

The Honda F-Series engine was considered Honda's "big block" SOHC inline four, though lower production DOHC versions of the F-series were built. It features a solid iron or aluminum open deck cast iron sleeved block and aluminum/magnesium cylinder head.SOHC engines[edit]F18A3[edit]Bore × Stroke: 85 mm × 81.5 mm (tiga.35 in × tiga.21 in)Displacement: 1.8 L (1,849 cc)Cylinder Configuration: Inline-4Valvetrain: SOHC, 16 valves115 hp (86 kW) up to 1997105 PS (77 kW) at 6,000 rpm, 14.6 kg⋅m (143 N⋅m; 106 lbf⋅ft) at 4,000 rpm (PGM-FI-injection, Throttle-body fuel injection)Fuel consumption: 13 km/L (37 mpg‑imp; 31 mpg‑US)

This engine was also used in the Rover 618i, assembled in Swindon at the Honda facility.F18B2[edit]

This engine was used for the Honda Accord European (CG8,CH6) from 1998-2002 VTEC S. Japan use variant (F18B) in (CD3,CF3) 1.8 VTS/VTE, from 1993-2002

This engine also spawned many variants, according to market, but the specs remain largely similar.

The F20A is used in the CB3 and CB4 Chassis.F20B[edit]

This engine series is similar to the F20A above, used in the Honda Accord CC7 (1993-1996) and CE8 (1996-1998) in Europe.

This engine is the low compression brother of F20Z1. This engine was used in the same models as the F20Z1.Specifications[edit]Bore × Stroke: 85 mm × 88 mm (tiga.35 in × tiga.46 in)Displacement: dua.0 L (1,997 cc)Compression Ratio: 9.0:1Valve Configuration: SOHC, 16 valves115 hp (86 kW) at lima,300 rpmF22A[edit]

This engine series was used in the Honda Accord and Honda Prelude S. Aside from differences in tuning, these engines are substantially similar.Specifications[edit]Bore × Stroke: 85 mm × 95 mm (3.35 in × tiga.74 in)Displacement: dua.2 L (2,156 cc)Valve configuration: SOHC, 16 valves, non-VTECCompression ratio: 8.8:1Max power:F22A1: 125 hp (93 kW) at lima,200 rpm. (Accord DX, LX). The 1992–1996 Prelude S also had a F22A1 but because of a different, more aggressively tuned ECU (P13) the power output is 135 hp (101 kW).F22A2: 145 hp (108 kW) at 5,600 rpm. Accord EXi 2WS 1990-1993, Prelude S and SI 1992-1996. dua.dua Lts. water-cooled SOHC with Sequential multi-port fuel injection engine without catalytic converter (KT/KY). Compression Ratio 8.9:1. This engine is equipped with the same camshaft from F22A6 engine, have the 4-1 header and simple intake manifold from F22A1 without IABS. Built to be supplied for the Gulf Market models, be they Accord and Prelude, this is a reason which is very unknown in America, and there is not so much information.F22A3: 150 hp (112 kW) European market engine, with more power due to less strict emission standards.F22A4: 130 hp (97 kW) at lima,200 rpm. (Accord EX) The F22A4 is the same motor as the F22A1 but it has slightly more power due to a tubular designed header and slightly bigger exhaust piping.F22A6: 140 hp (104 kW) at lima,600 rpm. The F22A6 is the same as the F22A1 except for a slightly more aggressive camshaft, a better flowing cast exhaust manifold, a different more aggressively tuned ECU (PT6), and a different intake manifoldthat utilizes IAB's and also has a bigger plenum. The F22A6 also has a windage tray in the oil pan, and stiffer valve springs to accommodate the more aggressive camshaft.In cars with an automatic transmission there is an oil cooler present on the back of the block as well.F22A7: 150 hp (112 kW) European domestic market engine, with more power due to less strict emission standards. (uses PT4, obd1 ecu) .Compression ratio: 9.8:1.F22A9 Australian delivered engine. Similar characteristics to the F22A6 European engine. More aggressive camshaft and slightly larger valves.

This engine was used in the 1994-1997 Honda Accord EX (1993 in JDM Accord models dua.2VTE, VTL & VTS) and the 1997 Acura CL.It was the first F-series engine to feature VTEC.Specifications[edit]Bore × Stroke: 85 mm × 95 mm (3.35 in × tiga.74 in)Displacement: 2.dua L (dua,156 cc)Piston Length: 65 mm (dua.6 in)Compression Ratio: 8.8:1Rod Length: 142 mm (lima.6 in)Rod Diameter: 51 mm (dua.0 in)Pin Diameter: 22 mm (0.87 in)Valvetrain: SOHC, 16 valves (4 valves per cylinder), VTECMax Power: 145 hp (108 kW) at lima,500 rpmMax Torque: 199 N⋅m (147 lb⋅ft) at 4,500 rpmVTEC Switchover: 2300~3200 rpm (depending on manifold pressure)Redline: 6,500 rpm (fuel cut-off action)Firing order: 1-3-4-duaFuel control: (1994–1995) OBD-I PGM-FI (1996–1998) OBD-II PGM-FIF22B5[edit]
