FA20D Subaru Engine

FA20D Subaru Engine

In contrast to a conventional throttle which used accelerator pedal effort to determine throttle angle, the FA20D engine had electronic throttle control which used the ECM to calculate the optimal throttle valve angle and a throttle control motor to control the angle.

  • The camshaft timing gear assembly contained advance and retard oil passages, as well as a detent oil passage to make intermediate locking possible.

  • Valve timing: D-AVCS To optimise valve overlap and utilise exhaust pulsation to enhance cylinder filling at high engine speeds, the FA20D engine had variable intake and exhaust valve timing, known as Subaru's 'Dual Active Valve Control System' D-AVCS.

  • The four valves per cylinder ÔÇö two intake and two exhaust ÔÇö were actuated by roller rocker arms which had built-in needle bearings that reduced the friction that occurred between the camshafts and the roller rocker arms which actuated the valves.
