EH Engines – EH65DS – 22.0 HP SUBARU EH Engine Series – Air Cooled, 4-Cycle, Horizontal & Vertical PTO Shaft Petrol Engines(Vertical Shaft only available V-Twins). Available from 4.0hp to 25hp.

(OHV) Overhead Valves Located in the Cylinder Head.

Valve actuation is via pushrod and rocker arm. In a four-stroke engine, the intake and exhaust valves are in the cylinder head. The valve stems are either at an angle or parallel, and the valve discs face the piston.

The upright cylinder on the SUBARU EH Series enables optimum lubrication and better performance when operated tilted. In combination with the overhead valve design, the use of expander oil rings has reduced the engine oil consumption rate by 50%. Any of the engines in the new PRO OHV series can easily be started with a light pull of the recoil starter. Electric starters are available as an option for the entire series. Noise emission is reduced and also vibration levels.

The EH64 was chosen by one company to build their fire fighting pumps for a Rural Fire Service because “they are the only small engine I’ve found that has the exhaust coming out the back rather than the front, so fire fighters are not at risk of burning themselves from the heat of the engine. Because of this rear exhaust the fire fighters don’t have to breathe the carbon monoxide fumes from the pump!”
