Subaru was the first to offer chain-driven overhead cam (OHC) technology in the small, air-cooled engine market with its Subaru Industrial EX engine series. [5] A standard for high-performance automotive engines, chain-driven OHC technology allows the intake and exhaust valves to be positioned for optimum engine performance.
The technology allows the intake and exhaust valves being positioned for optimum engine performance, which offers lower resistance for the air/fuel mixture flow. Overhead Cam engines also have fewer moving parts and produce less mechanical noise than competitive technologies. They also offer better cooling performance to combat overheating. [2]
For the first time in a Subaru engine, the centerlines of the cylinder bores do not intersect with the crankshaft axis to reduce friction during the piston downstroke; instead, there is a crank offset of 8 mm (0.31 in). Overall thermal efficiency is 40% due to the adoption of lean-burn combustion with an excess air ratio (λ) of 2. [32]
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 ...
