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.
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 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]

The Subaru Industrial SX engine series from Subaru Industrial Power Products are designed specifically for use with snow throwers, also known as snow blower. The line includes four models, the 6 horsepower SX17, the 7 horsepower SX21 and the 9.5 horsepower SX30 and the SX40-14 horsepower [ 1 ]
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 ...
Subaru Corporation (株式会社 SUBARU (スバル), Kabushiki-gaisha Subaru), formerly Fuji Heavy Industries, Ltd. (富士重工業株式会社, Fuji Jūkōgyō Kabushiki gaisha), is a Japanese multinational corporation and conglomerate primarily involved in both terrestrial and aerospace transportation manufacturing.
VW installed one engine in a Type 1 and another in a Type 2. [64] The Subaru engine was rated at 110 kW (150 PS; 148 hp) and 350 N⋅m (260 ft⋅lbf) with a displacement of 2.0 liters. In March 2008 Subaru offered the Legacy Sedan and Wagon and the Outback Wagon with 2.0 liter turbodiesel in the EU with a 5-speed manual transmission. [65]
