The Honda H engine was Honda's larger high-performance engine family from the 1990s and early 2000s. It is largely derived from the Honda F engine with which it shares many design features. Like Honda's other 4-cylinder families of the 1980s and 1990s, It has also enjoyed some success as a racing engine, forming the basis of Honda's touring car racing engines for many years, and being installed in lightweight chassis (such as the Honda CR-X) for use in drag racing. The F20B is a part of the F-series family of engines; it is basically a cast-iron sleeved down destroked version of the H22A. It was developed by Honda to be able to enter into the 2-liter class of international racing.
H-Series consisted of two different displacements; H22 2.2 L (2,157 cc) and H23 2.3 L (2,259 cc). Both versions were using the same block; different crankshafts and connecting rods were utilized to achieve displacement variation. [1]
The H22 debuted in the U.S. in 1993 as the H22A1 for use in the Honda Prelude VTEC. Since then, versions of the H22 would become the Prelude's signature high-performance engine worldwide until the end of Prelude production in 2001. In 1994, Honda of Europe used the H22A cylinder head and the H22A engine block as the Formula 3 engine which was an H22A engine destroked from 2.2 liters to 2.0 liters (F3-2000cc) to compete in the European F3 series. It was then used by Mugen Motorsports as the F20B(MF204B) from 1997-2001. In 1995-1997, Honda of Europe used the same H22A-based F3 engine in the British Touring Car Championship (BTCC) Honda Accord. Also, in 1996-1997 Honda of Japan used the same H22A-based F3 engine in the Japan Touring Car Championship (JTCC) Honda Accord and won the JTCC for both years. Honda of Europe hired Neil Brown Engineering of England to convert the H22A engine into an F3 engine which would be later used in BTCC and JTCC. The type S Prelude has an engine rev cut of 9100rpm.
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
In 1998, Honda of Japan produced a rare DOHC VTEC version of the H23A engine for use in Japan only. It has been factory modified with an internal oil passage in the H23A block to operate the VTEC solenoid in the H22A head. It has the same horsepower rating as the H22A engine but a lower redline of 7200rpms because it has a longer stroke than the H22A. The H23A DOHC VTEC has 87 mm × 95 mm (3.43 in × 3.74 in) (bore and stroke) and the H22A DOHC VTEC has 87 mm × 90.7 mm (3.43 in × 3.57 in) (bore and stroke). The H23A DOHC VTEC Engine is largest displacement in the H Series engines with a compression ratio of 10.6:1.

The Honda Accord, known as the Honda Inspire in Japan for certain generations, is a series of automobiles manufactured by Honda since 1976, best known for its four-door sedan variant, which has been one of the best-selling cars in the United States since 1989. The Accord nameplate has been applied to a variety of vehicles worldwide, including coupes, station wagons, hatchbacks and a Honda Crosstour crossover.
The Honda Prelude is a sports car which was produced by Japanese car manufacturer Honda from 1978 until 2001. The two-door coupe was loosely derived from the Honda Accord and spanned five generations. The Prelude was used by Honda to introduce the Japanese Honda retail sales chain Honda Verno, with the international release of the model following shortly after.
Honda Type R models are special performance editions of their respective model families.
The B-series are a family of inline four-cylinder DOHC automotive engines introduced by Honda in 1988. Sold concurrently with the D-series which were primarily SOHC engines designed for more economical applications, the B-series were a performance option featuring dual overhead cams along with the first application of Honda's VTEC system. To identify a Honda B-series engine, the letter B is normally followed by two numbers to designate the displacement of the engine, another letter, and in US-spec engines, another number. The Japanese spec-engines are normally designated with a four character alphanumeric designation. The B-series, the B20B variant in particular, is not to be confused with the earlier Honda B20A engine introduced in 1985 and primarily available in the Prelude and Accord-derived vehicles from 1985 to 1991. While sharing some design elements and both being multivalve Honda four-cylinders, the B-series and B20A differ substantially in architecture, enough to be considered distinct engine families.
Honda's first production V6 was the C series; it was produced in displacements from 2.0 to 3.5 liters. The C engine was produced in various forms for over 20 years (1985–2005), having first been used in the KA series Legend model, and its British sister car the Rover 800-series.
The Honda B20A engine series, known as the B20A and B21A was an inline four-cylinder engine family from Honda introduced in 1985 in the second-generation Honda Prelude. Also available in the contemporary third-generation Honda Accord in the Japanese domestic market, along with the Accord-derived Vigor, the B20A was Honda's first line of multivalve DOHC inline four-cylinder engines, focused towards performance and displacing 2.0 to 2.1 litres.
The F20C and F22C1 were inline-4 engines produced by Honda for use in the Honda S2000. They are one of the few Honda 4-cylinder automobile engines that are designed to sit longitudinally for rear wheel drive.
The E-series was a line of inline four-cylinder automobile engines designed and built by Honda for use in their cars in the 1970s and 1980s. These engines were notable for the use of CVCC technology, introduced in the ED1 engine in the 1975 Civic, which met 1970s emissions standards without using a catalytic converter.
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 timing. Power ranges from 66 PS (49 kW) in the Logo to 130 PS (96 kW) in the Civic Si. D-series production commenced 1984 and ended 2005. D-series engine technology culminated with production of the D15B 3-stage VTEC (D15Z7) which was available in markets outside of the United States. Earlier versions of this engine also used a single port fuel injection system Honda called PGM-CARB, signifying the carburetor was computer controlled.
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.
The L-series is a compact inline-four engine created by Honda, introduced in 2001 with the Honda Fit. It has 1.2 L (1,198 cc), 1.3 L (1,318 cc) and 1.5 litres (1,497 cc) displacement variants, which utilize the names L12A, L13A and L15A. Depending on the region, these engines are sold throughout the world in the 5-door Honda Brio Fit/Jazz hatchback Honda Civic and the 4-door Fit Aria/City sedan. They are also sold in the Japanese-only Airwave wagon and Mobilio MPV.
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 and utilizes Honda's i-VTEC system. The R series engine has a compression ratio of 10.5:1, features a "drive by wire" throttle system which is computer controlled to reduce pumping losses and create a smooth torque curve.
The Honda Torneo is a mid-size sedan introduced by Honda in 1997, exclusively for the Japanese domestic market, derived from the Honda Accord. While the Accord was sold exclusively at Honda Clio dealerships, the Torneo was available at the other two Honda networks, Honda Verno and Honda Primo as the successor to the Honda Ascot and Honda Rafaga, respectively. "Torneo" means tournament in Spanish.
In 1987, the Honda Civic was significantly redesigned for model year 1988. The suspension had a radical re-configuration with double wishbone suspension in the front and an independent suspension in the rear, wheelbase was increased to 98.4 inches (250 cm), and the body was redesigned with a lower hood line and more glass, giving less drag. The front suspension incorporates an extended hub carrier, so the upper arm is relatively short. The rear suspension is a multi-link trailing arm suspension with upper and lower lateral control links near the axle line and a short lateral link for toe control ahead of the pivot of the main trailing arm.
The fifth generation Honda Civic debuted in Japan on September 9, 1991. The Civic was larger than its predecessor, had a more aerodynamic body and the wheelbase was increased to 257 cm (101.3 inches) for the three-door hatchback and 262 cm (103.2 inches) for the four-door sedan. The wagon was also dropped for overseas markets, while the previous generation station wagon ("Shuttle") continued in Japan and Europe.
The sixth generation Honda Civic was introduced in 1995 with 3-door hatchback, 4-door sedan and 2-door coupe body styles, replicating its predecessor's lineup. A 5-door hatchback was also produced to replace the Honda Concerto hatchback in Europe but this model, while using the same design language as the rest of the Civic range, was quite distinct, instead being a hatchback version of the Honda Domani, sharing that car's platform which was related to the fifth-generation (EG/EH/EJ) Civic. The Domani replaced the sedan version of the Concerto in Japan while the sedan version of the Concerto was directly replaced by the sixth generation Civic sedan in other markets. Two wagons were also made available; the JDM Orthia, based on the Civic sedan/3-door hatchback line, and a 5-door hatchback/Domani-based model, sold as the Civic Aerodeck, in Europe. Neither were offered in North America. The Civic 5-door hatchback also formed the basis for the 1995 Rover 400 although the 4-door sedan version of the Rover was quite distinct from the Domani.
The seventh generation Honda Civic is an automobile which was produced by Honda from 2000 to 2005. It was released in September 2000 as a 2001 model. Compared to its predecessor, it retained similar exterior dimensions, but increased significantly in interior space thus bumping up Civic to a compact car size segment. There was a flat rear floor, giving better comfort to the rear seat passengers. This generation abandoned the front double wishbone suspension, which had been used in the fourth to sixth generations, replacing it with MacPherson strut. The seventh generation was the last to offer 4WD variants.
The eighth generation Honda Civic was introduced in September 2005, for the 2006 model year. This generation introduced the "two-tier" instrument panel. In many countries, all models come standard with power windows, anti-lock brakes (ABS), and side/curtain airbags. Additionally, the 2006 models acquired ULEV-2 certification and boast a more powerful 1.8-litre engine than the 2005 counterparts while retaining almost equal fuel economy.
The sixth generation Honda Accord was available as a four-door sedan or a two-door coupe and was produced by Honda from September 1997 to 2002.
