The larger displacement is achieved by increasing the stroke from 78 to 87 mm (3.1 to 3.4 in), but using the same bore of 86 mm (3.4 in). In aviation applications it is used as a direct drive engine, turning a propeller without a reduction drive. It employs a single electronic ignition system and produces 25 to 37 hp (19 to 28 kW) at 3600 rpm.
Since the electric pump does not require mechanical power from the engine, it is feasible to locate the pump anywhere between the engine and the fuel tank. The reasons that the fuel pump is typically located in the fuel tank are: By submerging the pump in fuel at the bottom of the tank, the pump is cooled by the surrounding fuel; Liquid fuel by ...
The engine was a 141cc 2-cycle that produced from 4 hp to 6.5 hp at 3700 to 4000 rpm on a 50:1 gas & oil mix. A higher power 7-HP model was made (Engine Model# 84330) for use in heavier duty machines such as the single stage Snow Commander (2001–2008) and 2 stage Power Max 726TE/6000 (2004–2008); the extra horsepower was obtained using ...
The system’s easy-fill cap and integrated oil filter make oil changes easier, cleaner and faster. Oil Guard boasts a robust 192-oz system capacity to help keep both the oil and engine cooler. The mower models will also benefit from Vanguard electronic fuel injection (EFI) and electronic throttle control (ETC) technologies.
These engines were designed to have a total-loss lubrication system, with the motor oil held in a separate tank from the fuel in the vehicle, and not pre-mixed with it as with two-cycle engines, but mixed within the engine instead while running. Castor oil was often used because it lubricates well at the high temperatures found in air-cooled ...
The oil is contained in a reservoir that connects to a small oil pump in the engine, which needs to be periodically refilled. Oil injection pump on a Yamaha DX100- just behind the carburettor (visible on the left) It is the primary component of two-stroke automatic lubrication system. Amount of two-stroke oil injected by the pump depends on the ...

An oil pump, a vane or gear pump powered by the engine, pumps the oil throughout the engine, including the oil filter. Oil filters can be a full flow or bypass type. In the crankcase of a vehicle engine, motor oil lubricates rotating or sliding surfaces between the crankshaft journal bearings (main bearings and big-end bearings) and rods ...
