Honda F20C Engine
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. These engines are related to the F-series engines found in the mid-1990s Honda Accord and Prelude. To get most out of the compact-sized engine, Honda engineers utilized technology derived from Honda's racing engines. The F20C and F22C1 have two overhead cams with roller followers, a ladder-frame main bearing stiffener, a VTEC system for both the intake and exhaust camshaft, Fiber-Reinforced Metal cylinder liners (FRM), Forged aluminum molybdenum disulfide-coated piston skirts for reduced friction, and uses a timing chain. The VTEC system consists of two separate cam lobe profiles. Variable cam phasing is not used. Roller followers are used to reduce friction in the valvetrain. The rocker arms are constructed using metal injection molding. The engine block is construc ...

Rocker Arm
A rocker arm is a valvetrain component that typically transfers the motion of a pushrod in an overhead valve engine, overhead valve internal combustion engine to the corresponding intake/exhaust poppet valve, valve. Rocker arms in automobiles are typically made from stamped steel, or aluminum in higher-revving applications. Some rocker arms (called ''roller rockers'') include a bearing at the contact point, to reduce wear and friction there. Overview The most common use of a rocker arm is to transfer the up and down motion of a pushrod in an overhead valve engine, overhead valve (OHV) internal combustion engine to the corresponding intake/exhaust poppet valve, valve. In an OHV engine the camshaft located within the engine block below the cylinder bank(s) pushes the pushrod upwards. The top of the pushrod presses upwards on one side of the rocker arm located at the top of the cylinder head, which causes the rocker arm to pivot downward on the top of the valve, opening it. To redu ...

Honda S800
The S800 is a sports car from Honda. Introduced at the 1965 Tokyo Motor Show, the S800 replaced the successful Honda S600 as the company's image car. With a redline of 8,500 rpm, it is one of the highest-revving sports cars produced for street use. The S800 competed with the Austin-Healey Sprite, MG Midget, Triumph Spitfire, Datsun Fairlady, and Fiat 850 Spider. History Like the S600, the S800 was available as either a coupe or roadster, and continued the advanced technology of its predecessors. The 791 cc straight-4 engine produced 70 hp (52 kW) at 8000 rpm, thus making this Honda's first 100 mph (160 km/h) automobile, but still allowing for 35 mpg (6.7 L/100 km). In April 1967 the car was described as the fastest production 1-litre car in the world thanks to its high revving engine (up to 10,000 rpm) and the manufacturer's history of manufacturing powerful relatively low capacity motor-cycle engines. Early examples continued to use the c ...

Honda S600
The Honda S600 is an automobile manufactured by Honda. It was launched in March 1964. Available as a roadster, bearing strong resemblance to the Honda S500, and as a fastback coupé, introduced in March 1965, the S600 was the first Honda available in two trim levels. During its production run up to 1966, the model styling would remain pretty much the same, with the most notable changes coming to the front grille, bumper, and headlights. Specifications Powered by a DOHC, water-cooled, four-cylinder inline engine with four Keihin carburetors, the engine capacity was increased to 606 cc from the S500's 531 cc. The engine produced at 8,500 rpm and had a top speed of . With the convertible weighing in at mere , the extra sheet metal of the coupe only added to the overall weight. A four speed manual transmission drove the rear wheels via a hypoid differential outputting to chain final drives for each rear wheel. Each wheel was driven by either single or dual chai ...

Honda S500
The Honda S500 was the second production car model manufactured by Honda (and its first passenger automobile), released in 1963, following the T360 truck into production by four months. It was a larger-displacement variant of the S360 roadster which, though developed for sale in 1962, was never produced. Design Like the S360, the S500 used a high-tech engine developed from Honda's motorcycle expertise. It was a dual overhead cam straight-4 with four Keihin carburetors and a 9500 rpm redline. Originally intended to displace 492 cc, the production version was 531 cc and produced at 8000 rpm.Buckley, Martin.''The Illustrated Book of Classic Cars''. Anness Publishing Ltd, 1997, 2003, p. 146. At the time of its introduction, its dimensions and engine displacement were larger than established kei car regulations. The S500 used a four-speed manual transmission. A four-wheel independent suspension was also novel, with torsion bars at the front and chain-driven, coilo ...

Mean Piston Speed
The mean piston speed is the average speed of the piston in a reciprocating engine. It is a function of stroke and RPM. There is a factor of 2 in the equation to account for one stroke to occur in 1/2 of a crank revolution (or alternatively: two strokes per one crank revolution) and a '60' to convert seconds from minutes in the RPM term. :V_\text = 2*\frac * \frac For example, a piston in an automobile engine which has a stroke of 90 mm will have a mean speed at 3000 rpm of 2 * (90 / 1000) * 3000 / 60 = 9 m/s. The 5.2-liter V10 that debuted in the 2009 Audi R8 has the highest mean piston speed for any production car (26.9 m/s) thanks to its 92.8 mm stroke and 8700-rpm redline. Classes ; low speed diesels : ~8.5 m/s for marine and electric power generation applications ; medium speed diesels : ~11 m/s for trains or trucks ; high speed diesel : ~14–17 m/s for automobile engines ; medium speed petrol : ~16 m/s for automobile engines ; high ...

United States Domestic Market
The term United States domestic market (USDM) is an unofficial term used chiefly by automotive enthusiasts to describe the United States' economic market for American brand automobiles and parts. Similar automotive enthusiast terms Japanese domestic market (JDM) and European domestic market (EDM) are used to designate Japanese and European market automobiles and parts respectively. The term is also applied to vehicles that comply with United States regulations, most notably the lights and bumpers, which different from European standards. The incompatibility requires manufacturers to develop USDM and EDM versions of their models if they want to sell them in both regions. Sometimes the conversion in the factory lane is done after the model was launched in the European market. The conversion to United States federal laws is often called "federalization". The term is sometimes used in the context of commodities. See also * Tariffs in the second Trump administration During Secon ...

Japanese Domestic Market
The term "Japanese domestic market" ("JDM") refers to Japan's home market for vehicles and vehicle parts. Japanese owners contend with a strict motor vehicle inspection and grey markets. JDM is also incorrectly used as a term colloquially to refer to cars produced in Japan but sold in other countries. The average age of JDM cars is 8.7 years, ranking 9th in a survey of 30 of the top 50 countries by gross domestic product. According to the Fédération Internationale de l'Automobile, a car in Japan travels a yearly average of over only , less than half the U.S. average of . 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 innovation than long-term ownership which forces Japanese carmakers to refine new technologies and designs first in domestic vehicles. For instance, the 2003 Honda Inspire featured the fi ...

Catalytic Converter
A catalytic converter part is an vehicle emissions control, exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalysis, catalyzing a redox chemical reaction, reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel fuel, diesel, including lean-burn engines, and sometimes on kerosene heaters and stoves. The first widespread introduction of catalytic converters was in the United States automobile market. To comply with the United States Environmental Protection Agency, U.S. Environmental Protection Agency's stricter regulation of exhaust emissions, most gasoline-powered vehicles starting with the 1975 model year are equipped with catalytic converters. These "two-way" oxidation converters combine oxygen with carbon monoxide (CO) and unburned hydrocarbons (HC) to produce carbon dioxide (CO2) and water (H2O). "Three-way" conve ...
