The Intelligence-Active Valve Lift System (i-AVLS) is a valvetrain technology implemented by Subaru in their 2.5 L SOHC naturally aspirated engine to improve emissions, efficiency and performance. Note that AVLS is different from AVCS used on other Subaru engines.
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", [1] in order to provide optimal valve timing for engine load conditions. The system is closed loop using the camshaft sensors ...
The FB has an all new block and head featuring dual overhead cams with intake and exhaust variable valve timing (AVCS - Active Valve Control System), and a timing chain that replaced the timing belt. Moving to chain-driven cams allows the valves to be placed at a more narrow angle to each other and shrinks the cylinder bore from 99.5 mm to 94.
Subaru Alcyone VX. Created as a refined luxury engine with improved power over the EA82T, Subaru introduced the ER27 engine in November 1985 for the Subaru ACX-II concept car, shown at the Tokyo Motor Show and billed as the 'concept car of the near future.' [2] The concept went into production as the Subaru Alcyone VX (Subaru XT6 in North America) in August 1987, [3] the exclusive application ...
The EJ20X and EJ20Y engines were equipped with Subaru's ‘Dual Active Valve Control System’ (‘Dual AVCS’) which provided variable intake and exhaust valve timing. The Legacy GT, the EJ20X engine was fitted with a twin-scroll IHI VF38 turbocharger; the EJ20Y engine, however, had a larger twin-scroll Mitsubishi TD04 HLA 19T turbocharger.
The Subaru EA-71 engine was produced in two different designs; from 1976 to 1994, originally the first design was a redesign of the EA-63 block, known as the "Narrow Case EA71" then Subaru completely redesigned it to make the newer version known as "Fat Case EA71" which also led to a stroked version known as the EA81. The availability in USA ...
In terms of safety, the GD chassis scored much higher than the GC chassis and earned a "Good" rating (highest mark) from the IIHS's offset crash test. 4 stars front driver, 5-star front passenger and 4-star side safety ratings from the NHTSA. In Subaru's home market of Japan, the Impreza range started with the 1.5i—powered by the 1.5-liter ...
