Subaru EJ Engine
The Subaru EJ engine is a series of four-stroke automotive engines manufactured by Subaru. They were introduced in 1989, intended to succeed the previous Subaru EA engine. The EJ series was the mainstay of Subaru's engine line, with all engines of this series being 16-valve horizontal Flat-four engine, flat-fours, with configurations available for single, or double-overhead camshaft arrangements (Overhead camshaft#Single overhead camshaft, SOHC or Overhead camshaft#Dual overhead camshaft, DOHC). Naturally aspirated and turbocharged versions are available, ranging from . These engines are commonly used in light aircraft, kit cars and engine swaps into air-cooled Volkswagens, and are also popular as a swap into Volkswagen Type 2 (T3), Volkswagen T3/Vanagons powered by the Volkswagen Wasserboxer engine. Primary engineering on the EJ series was done by Masayuki Kodama, Takemasa Yamada and Shuji Sawafuji of Fuji Heavy Industries, Subaru's parent company. EJ15 (1.5L Boxer NA) Usage: ...

Subaru
is the automaker, automobile manufacturing division of Japanese transportation conglomerate (company), conglomerate Subaru Corporation (formerly known as Fuji Heavy Industries), the Automotive industry#By manufacturer, twenty-first largest automaker by production worldwide in 2017. Subaru cars are known for their use of a flat engine, boxer engine layout in most vehicles above 1,500 cc. The Symmetrical All Wheel Drive drive-train layout was introduced in 1972. Both became standard equipment for mid-size and smaller cars in most markets by 1996. The lone exception is the Subaru BRZ, BRZ, introduced in 2012 via a partnership with Toyota, which pairs the boxer engine with rear-wheel-drive. Subaru also offers turbocharged versions of their passenger cars, such as the Subaru WRX, WRX, Subaru Outback, Levorg sti, Outback XT, Subaru Ascent, Ascent, and formerly the Subaru Legacy, Legacy GT, Subaru Legacy, Legacy XT, and Subaru Forester, Forester XT. In Western markets, Subaru ve ...

Volkswagen Wasserboxer Engine
The Volkswagen wasserboxer is an overhead-valve (OHV), flat four-cylinder boxer petrol engine developed by Volkswagen. "Wasserboxer", abbreviated as WBX, is a German compound noun where "wasser" indicates that the engine is water-cooled, and "boxer" describes the arrangement and movement of the pistons. Details The wasserboxer features a cast aluminium alloy cylinder block, cylinder heads, and pistons; and a die-forged steel flat plane crankshaft with four main bearings. As in Volkswagen's earlier air-cooled luftboxer engines, the wasserboxer's three-bearing camshaft is driven directly from the crankshaft by means of a small steel gear on the crankshaft and a larger aluminium gear on the camshaft, with the whole mechanism internal to the engine. The overhead poppet valves each feature two concentric valve springs, and are operated by pushrods and rocker arms, which are adjustable to facilitate setting valve clearances. The wasserboxer also features a " Heron cylinder head ...

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 ...

Subaru Legacy
The is a mid-size car built by Japanese automobile manufacturer Subaru from 1989 to 2025. The maker's flagship car, it is unique in its class for offering all-wheel drive as a standard feature, and Subaru's traditional boxer engine. The Legacy was sold as the Liberty in Australia out of deference to Legacy Australia, an organisation dedicated to caring for the families of military service veterans. In 1996, a variant of the Legacy with heightened suspension called the Legacy Outback was introduced to compete in the burgeoning sport-utility vehicle class, and proved to be a sales success for Subaru. The Outback line was split into its own model in 2008, known as the Subaru Outback. As of 2008, 3.6 million Legacy models have been built since its 1989 introduction. Production of the Legacy ended in Japan in June 2020, with the sixth-generation Legacy being the last model produced and marketed in Japan. Subaru of America announced in an internal email that 2025 will be the l ...

Naturally Aspirated
A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a turbocharger or a supercharger. Description In a naturally aspirated engine, air for combustion (Diesel cycle in a diesel engine or specific types of Otto cycle in petrol engines, namely Gasoline direct injection, petrol direct injection) or an air/fuel mixture (traditional Otto cycle petrol engines), is drawn into the engine's cylinder (engine), cylinders by atmospheric pressure acting against a Vacuum, partial vacuum that occurs as the piston travels downwards toward Dead centre (engineering), bottom dead centre during the intake stroke (engine), stroke. Owing to innate restriction in the engine's inlet tract, which includes the Inlet manifold, intake manifold, a small pressure drop occurs as air is drawn in, resulting in a volumetric effici ...

Tokyo Motor Show
The , called (TMS) until 2023, is a biennial auto show held in October–November at the Tokyo Big Sight, Tokyo, Japan for cars, motorcycles and commercial vehicles. Hosted by the Japan Automobile Manufacturers Association (JAMA), it is a recognized international show by the Organisation Internationale des Constructeurs d'Automobiles, and normally sees more concept cars than actual production car introductions, which is the reason why the automotive press sees the show as one of the motorshow's big five (along with North American International Auto Show, Detroit, Geneva Motor Show, Geneva, Frankfurt Motor Show, Frankfurt and Mondial de l'Automobile, Paris). For the first time in its 67-year history, the show was cancelled for 2021 due to rising cases of COVID-19. History The show, originally called All Japan Motor Show was first held in an outdoor venue called Hibiya Park, the show was considered a success with 547,000 visitors over ten days and 254 exhibitors displaying 26 ...

Isuzu Aska
The Isuzu Aska was a nameplate used by Isuzu of Japan to denote its mid-size sedans from 1983 to 2002. Originally the Aska was a version of General Motors' J-car produced by Isuzu, but after Isuzu pulled out of manufacturing passenger cars the nameplate was applied to rebadged versions of the Subaru Legacy (1990 to 1993) and Honda Accord (1994 to 2002) sold through Isuzu's Japanese distribution network. The Aska replaced the Isuzu Florian in Isuzu's lineup and was discontinued in 2002 without a replacement. The name comes from the Japanese word, "Asuka", which is the old name of the Asuka Village in the Nara Prefecture of Japan. Because the name "Asuka" is likely to be mispronounced in foreign countries, the "u" was taken away from the name, presenting the model as the "Aska". __TOC__ First generation (1983–1989) The original Aska was developed as a part of GM's ''J-car'' program and was a replacement for Isuzu's dated Florian. In contrast to fellow J-cars from othe ...

Subaru Legacy (first Generation)
The first generation Subaru Legacy is a mid-size family car / wagon developed by Fuji Heavy Industries. The Legacy was an all new model, and was considered a notable departure from Subaru products in the past. History The worldwide introduction of the Legacy sedan and wagon was achieved in 1989. Subaru had earned a reputation of building vehicles that were regarded as "quirky" while other Asian manufacturers were bringing more upscale and conventional appearing models to the market. The Legacy was different and became a solid production that changed Subaru's reputation. The Legacy appeared at the same time as the US introduction of Lexus and Infiniti and five years after Acura, and it was interpreted by some as Subaru's attempt at participating in the emerging imported luxury car market. However, Subaru did not have a V6 or V8 engine. The Legacy was more automotive aerodynamic than previously built products, with soft edges and a more coherent appearance. The sedan has a break ...

SOHC
An overhead camshaft (OHC) engine is a piston engine in which 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 ...
