EJ25
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-fours, with configurations available for single, or double-overhead camshaft arrangements (SOHC or 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 copy wasserboxer engined Volkswagen T3/Vanagon. 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: * Impreza GC1 series ( JDM) - Replaced by Subaru EL engine in 2006 GD, GG, GE & GH series ( JDM) Impreza. * Impreza 93-06 (Latin America) S ...

Subaru Impreza
The is a compact car that has been manufactured by the Japanese automaker Subaru since 1992. It was introduced as a replacement for the Subaru Leone, Leone, with the predecessor's Subaru EA engine, EA series engines replaced by the new Subaru EJ engine, EJ series. It is now in its sixth generation. Subaru has offered a 5-door hatchback body variant since 2008. The firm also offered a coupé from 1995 until 2001, a 4-door sedan (automobile), sedan up to the fifth generation and a 5-door Station wagon, wagon from the Impreza's introduction - this was replaced by a hatchback with the third generation in 2008. Mainstream versions have received "boxer" flat-four engines ranging from 1.5- to 2.5-liters, with the performance-oriented Impreza WRX and WRX STI models upgraded with the addition of turbochargers. Since the third generation series, some markets have adopted the abbreviated Subaru WRX (VA), Subaru WRX name for these high-performance variants. The first three generations of Imp ...

Subaru Forester
The is a compact crossover SUV that has been manufactured by Subaru since 1997. The first generation was built on the platform of the Impreza in the style of a taller station wagon, a style that continued to the second generation, while the third-generation model onwards moved towards a crossover SUV design. A performance model was available for the second-generation Forester in Japan as the Forester STi. First generation (SF; 1997) The Forester was introduced at the Tokyo Motor Show in November 1995 as the Streega concept, and available for sale in February 1997 in Japan, and to the US market in 1997 for MY1998. The Forester was one of the first crossover SUVs; the idea was inspired by Volkswagen (VW). It was built in the style of a station wagon, but had a taller stance, higher h-point seating, and an all-wheel drive drivetrain. Subaru advertising employed the slogan "SUV tough, Car Easy". It used the Impreza platform but with the larger 2.5-liter DOHC EJ25D four-cyli ...

Subaru Legacy
The is a mid-size car built by Japanese automobile manufacturer Subaru since 1989. 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 last model being produced and marketed in Japan. First generation (BC/BF/BJ; 1989) The Legacy was introduced in 1989 to provi ...

Active Valve Control System
The active valve control system (AVCS) is an automobile variable valve timing technology used by Subaru. It varies the timing of the valves by using hydraulic oil pressure to rotate the camshaft, known as "phasing", in order to provide optimal valve timing for engine load conditions. The system is closed loop using the camshaft sensors, crankshaft sensors, air flow meter, throttle position as well as oxygen sensors and/or Air-Fuel ratio sensors in order to calculate engine load. The ECU is programmed to operate control valves that adjust the delivery of the hydraulic pressure in order to move the camshaft into the position that will provide the engine with the best performance while meeting emissions standards. AVCS is used on the Version 7 and up EJ207 engines, the EJ204, EJ254, EJ255, EJ257, the second generation EZ30D (2005+ in the USA market) found in the Legacy Outback, Legacy 2.0R, 3.0R and the B9 Tribeca. A dual AVCS system phases both the intake and exhaust camshafts on ...

Multi-valve
In automotive engineering a multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing and may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power. Multi-valve rationale Multi-valve engine design A multi-valve engine design has three, four, or five valves per cylinder to achieve improved performance. Any four-stroke internal combustion engine needs at least two valves per cylinder: one for ''intake'' of air (and often fuel), and another for ''exhaust'' of combustion gases. Adding more valves increases valve area and improves the flow of intake and exhaust gases, thereby enhancing combustion, volumetric efficiency, and power output. Multi-valve geometry allows the spark plug to be ideally located within the combustion chamber for optimal flame propagation. Multi-valve engines tend to have smaller valves that have lower reciprocating mass, which ...

Subaru FB Engine
The Subaru FB engine is the third and current generation of gasoline boxer-4 engine used in Subaru automobiles, and was announced on 23 September 2010. It follows the previous generation EJ-series engine which was introduced in 1989 and the first generation EA-series which was introduced in 1966. By increasing piston stroke and decreasing piston bore, Subaru aimed to reduce emissions and improve fuel economy, while increasing and broadening torque output compared to the EJ-series. The Subaru FA engine series was derived later from the FB, but the two engine families share only a few common parts. In 2020, Subaru introduced the CB18 engine with improved efficiency to succeed the FB in several applications. Overview Unofficially, Subaru stated that "FB" stands for " FHI/Future and Brand New/Boxer". It was announced in September 2010 as the third generation (following the EA 1st and EJ 2nd generations) boxer engine family with 2.0 litre and 2.5 litre naturally aspirat ...

Volkswagen Type 2 (T3)
The Volkswagen Type 2 (T3) was the third generation of the Volkswagen Transporter and was marketed under various nameplates worldwide – including the Transporter or Caravelle in Europe, T25 in the UK, Microbus in South Africa, and Vanagon in North and South America. It was larger, heavier, and more angular in its styling than its predecessor, the T2 but shared the same rear-engine, cab-over design. It was produced in a rear wheel drive version as well as a 4WD version marketed as "Syncro." The T3 was manufactured in Hannover, Germany from 1979 until 1991. Production of the Syncro (mostly for official use, like postal service or German army) continued until 1992 at Puch in Graz, Austria, where all 4WDs were built. A limited number of 2WD models were also produced at the Graz factory after German production had come to an end. South African production of the T3 continued, for that market only, until 2002. The T3 was the final generation of rear-engined Volkswagens. His ...

SOHC
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 O ...

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 ...

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. The earlier sedan and wagon are becoming more rare and collectables especially the earlier wagons. 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 ...
