A Honda K24A Engine with i-VTEC. VTEC (described as Variable Valve Timing & Lift Electronic Control, but stands for Valve Timing Electronically Controlled) is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM.
15.4–19.4 kg⋅m (151–190 N⋅m; 111–140 lb⋅ft) The Honda R engine is an inline-four engine launched in 2006 for the Honda Civic (non-Si). It is fuel injected, has an aluminum-alloy cylinder block and cylinder head, is a SOHC 16-valve design (four valves per cylinder) and utilizes Honda's i-VTEC system. The R series engine has a ...
Valve configuration: SOHC, 16 valves, non-VTEC; Compression ratio: 8.8:1; Max power: F22A1: 125 hp (93 kW) at 5,200 rpm. (Accord DX, LX). The 1992–1996 Prelude S also has a F22A1 but because of a different, more aggressively tuned ECU (P12) the power output is 135 hp (101 kW). F22A2: 145 hp (108 kW) at 5,600 rpm.
The VTEC operation was further refined such that in gears 1–5 four-valve operation engaged at 6,300 rpm for wide open throttle, otherwise at 6,750 rpm, and remaining at 6,750 rpm in 6th gear. Independent cylinder ignition timing map, revised air intake geometry and a larger stainless steel muffler contribute to fuel efficiency .
In late 1989, a new trim package was added called the SiR which came equipped with a 1.6-litre DOHC VTEC 16-valve 4-cylinder B16A engine producing 160 PS (118 kW; 158 hp) at 7,600 rpm. This first B series engine, marked the introduction of Honda's variable valve timing and electronic lift control technology .
The Honda D series inline-four cylinder engine is used in a variety of compact models, most commonly the Honda Civic, CRX, Logo, Stream, and first-generation Integra. Engine displacement ranges between 1.2 and 1.7 liters. The D Series engine is either SOHC or DOHC, and might include VTEC variable valve lift. Power ranges from 66 PS (49 kW) in ...
The H23 was an increased-stroke, non-VTEC version of the H22, used in Japan, North America, and Europe. It shared the same Fiber Reinforced Metal (FRM) cylinder wall liners with the H22. Specifications. Bore × Stroke: 87 mm × 95 mm (3.43 in × 3.74 in) Displacement: 2.3 L; 137.9 cu in (2,259 cc) Valve Configuration: DOHC, 16 valves
In September 1989, Honda added the 1.6-litre 16-valve DOHC VTEC 4-cylinder B16A engine to the lineup outside of North America. The VTEC (variable valve timing and lift electronic control) engine provided increased power at high RPMs while still allowing low fuel consumption and better idling at low RPMs.
