Honda B20A Engine
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 second line of multivalve DOHC inline four-cylinder engines behind the "ZC" twin-cam variant of the ordinarily SOHC D-series, focused towards performance and displacing 2.0 to 2.1 litres. The third-generation Prelude was exclusively powered by the B20A engine family and production of the B20A engine family ended with the conclusion of the production of the third-generation Prelude in 1991. History The B20A would be succeeded by the Honda B engine family. Although sharing similar nomenclature and some design elements, the earlier B20A substantially differs from the later B-series in architecture enough to be considered two different engine families and is al ...

DOHC
An overhead camshaft (OHC) engine is a piston engine where the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam".) engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; however an OHV ...

Honda B Engine
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 (available in some models). 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 archi ...

Honda Prelude
The Honda Prelude is a car 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. Production of the Prelude concluded in 2001 upon the introduction of the fourth-generation Integra. The Prelude name was originally trademarked by Toyota, but was amicably given to Honda for use. The Prelude complied with the series of music-themed vehicle names which Honda used at the time, along with the Accord, Quintet, Concerto, Jazz, and Ballade. First generation (1978) On 24 November 1978, the Prelude was launched to the Japanese market. It had its world premiere at the 1979 AutoRAI in Amsterdam, two months later. In Japan it was only available at the newly established dealership sales channel ''Honda Verno''. This dealershi ...

Honda Accord
The , also known as the in Japan and China for certain generations, is a series of cars 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. Since its initiation, Honda has offered several different car body styles and versions of the Accord, and often vehicles marketed under the Accord nameplate concurrently in different regions differ quite substantially. It debuted in 1976, as a compact hatchback, though this style only lasted through 1989, as the lineup was expanded to include a sedan, coupe, and wagon. By the sixth-generation Accord at the end of the 1990s, it evolved into an intermediate vehicle, with one basic platform but with different bodies and proportions to increase its competitiveness against its rivals in diffe ...

Japanese Domestic Market
Japanese domestic market (JDM) refers to Japan's home market for vehicles and vehicle parts. There is a common misconception that any Japanese branded car is JDM; however, this is not true. Only a vehicle made in Japan specifically to be sold in Japan is considered JDM. JDM market cars when compared to the United States market where vehicle owners are now owning vehicles for a longer period of time, with the average age of the American vehicle fleet at 10.8 years, Japanese owners contend with a strict motor vehicle inspection and gray markets. According to the Fédération Internationale de l'Automobile, a car in Japan travels a yearly average of over only 9,300 kilometers (5,800 miles), less than half the U.S. average of 19,200 kilometers (12,000 miles). Japanese domestic market vehicles may differ greatly from the cars that Japanese manufacturers build for export and vehicles derived from the same platforms built in other countries. The Japanese car owner looks more toward ...

Honda CR-V
The Honda CR-V (also sold as the Honda Breeze in China since 2019) is a compact crossover SUV manufactured by the Japanese automaker Honda since 1995. The early model was built using the same platform as the Civic. Honda began producing the CR-V in Sayama, Japan, and Swindon, United Kingdom, for worldwide markets, adding North American manufacturing sites in East Liberty, Ohio, United States, in 2007; El Salto, Jalisco, Mexico, in late 2007 (ended in early 2017); Alliston, Ontario, Canada, in 2012; and Greensburg, Indiana, United States, in February 2017. The CR-V is also produced in Wuhan for the Chinese market by Dongfeng Honda, and also marketed as the Breeze in China for the version produced at Guangzhou by Guangqi Honda. Honda states "CR-V" stands for "Comfortable Runabout Vehicle," while the term "Compact Recreational Vehicle" is used in a British car review article that was republished by Honda. , the CR-V is positioned between the smaller ZR-V (marketed as HR-V in No ...

Honda Vigor
The is a premium sedan that was derived from the Honda Accord. It was sold in Japan through the ''Honda Verno'' dealer network from 1981 until 1995, and sold in North America from June 1991 (model year 1992) until 1994 as the Acura Vigor. Early Vigors were more upmarket versions of the Accord, and served as Honda's flagship until the arrival of the Honda Legend. In 1989, the Vigor would differentiate itself further from the Accord with unique styling and an available longitudinal five-cylinder engine, and a twin to the Vigor was introduced with the Honda Inspire, available at ''Honda Clio'' dealerships. It was replaced in North America with the Acura TL and in Japan with the Honda Saber/Inspire, which were the same vehicle sold through different networks. The third generation, five-cylinder Vigor was developed during what was known in Japan as the Japanese asset price bubble or "bubble economy". __TOC__ First generation (SZ/AD) Beginning September 25, 1981, Honda produced ...

Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ...

Metal Matrix Composite
In materials science, a metal matrix composite (MMC) is a composite material with fibers or particles dispersed in a metallic matrix, such as copper, aluminum, or steel. The secondary phase is typically a ceramic (such as alumina or silicon carbide) or another metal (such as steel). They are typically classified according to the type of reinforcement: short discontinuous fibers (whiskers), continuous fibers, or particulates. There is some overlap between MMCs and cermets, with the latter typically consisting of less than 20% metal by volume. When at least three materials are present, it is called a hybrid composite. MMCs can have much higher strength-to-weight ratios, stiffness, and ductility than traditional materials, so they are often used in demanding applications. MMCs typically have lower thermal and electrical conductivity and poor resistance to radiation, limiting their use in the very harshest environments. Composition MMCs are made by dispersing a reinforcing material ...
