  • Active valve control system

    serch.it?q=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 minding emissions standards. AVCS is used on the Version 7 and up EJ207 engines, the EJ204, , EJ254, EJ255 and EJ257, the second generation EZ30D (2005+ in the USA Market) found in the Legacy Outback, Legacy 2.0R and 3.0R and the B9 Tribeca. A Dual AVCS system phases both the intake and exhaust camshafts on the EZ36 found in the 2008+ Tribeca, 2009+ Outback 3.6R, 2009+ Legacy 3.6R, and on the 2008+ STi EJ257 (W25 heads). Dual AVCS is present on the new FA20 engines in the 2015+ WRX, Forester and BRZ and the FB20 engines in the 2012+ Impreza / Crosstrek, though they actuate with a different method than those of the older engines. Dual AVCS is also found on Japanese Spec engines, notably the late model EJ207s in the WRX STI.

  • Subaru Tribeca

    serch.it?q=Subaru-Tribeca

    The Subaru Tribeca is a mid-size crossover SUV made from 2005 to 2014. Released in some markets, including Canada, as the Subaru B9 Tribeca, the name "Tribeca" derives from the Tribeca neighborhood of New York City. Built on the Subaru Legacy platform and sold in five- and seven-seat configurations, the Tribeca was intended to be sold alongside a slightly revised version known as the Saab 9-6. Saab, at the time a subsidiary of General Motors (GM), abandoned the 9-6 program just prior to its release subsequent to GM's 2005 divestiture of its 20 percent stake in FHI. Inspired by the B9X concept car, the Tribeca's original design was criticized at launch and subsequently revised in 2007 for the 2008 model year, and the model name was shortened to simply Tribeca in all markets. Although not sold in Japan, North American markets received the Tribeca in 2005 for the 2006 model year, and it was introduced to Australasia and Europe in late 2006. In addition to these markets, the Tribeca was also available in Chile, Argentina, Brazil, China, and parts of Southeast Asia.

  • Subaru BRAT

    The Subaru BRAT, short for "Bi-drive Recreational All-terrain Transporter", known outside Canada and the United States as the 284 in the United Kingdom, Brumby in Australia, and Shifter, MV, or Targa in other markets, is a light duty, four-wheel drive coupé utility, sold from 1978 to 1994. It was an export-only model, never being officially sold in Japan. Due to this, the BRAT became a popular grey import vehicle in Japan.
