Two-stroke engines, and most model engines, have a total-loss lubrication system. Lubricating oil is mixed with the fuel, either manually beforehand (the petroil method), or automatically via an oil pump. Prior to being burned in the combustion chamber, this air/fuel/oil mixture passes through the engine's crankcase, lubricating the moving ...
[2] [3] There are advantages of using an automatic lubrication system over a manual system. For example, there are savings in the costs of human resources. The dangers of accessing difficult to reach lubrication points while a machine is running are avoided. Machines can be running when lubrication takes place, thus decreasing disruption to ...
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 throttle position. A cable from the throttle is connected to the oil pump indicating throttle's position. A tube ensures flow ...
The oil collects in sump (1), is withdrawn continuously by scavenge pump (2) and travels to the oil tank (3), where gases entrained in the oil separate and the oil cools. Gases (6) are returned to the engine sump. Pressure pump (4) forces the de-gassed and cooled oil (5) back to the engine's lubrication points (7).
Electric pump as a main engine pump again will require big electric motors and it may be simply cheaper to drive directly from the engine. For e.g. BMW S65 engine's oil pump delivers ca. 45 LPM (Litres Per Minute) of oil at 5.5 bar pressure. [5] This pump would require a significantly large motor to drive.
The pumps of the DV type lubricator are operated by a sliding shaft assembly, unlike the Silverton or Wakefield lubricators which are operated by a rotating camshaft. [6] The FSA type lubricator differs by each pump having two separate pistons to control the pumping & distribution of oil. The pistons are driven by cams on the driving shaft.
1919 Napier Lion II aircraft engine with three cylinder banks. Any design of motor/engine,be it a V or a boxer can be called an "in-line" if it's mounted in-line with the frame/chassis and in-line with the direction of travel of the vehicle.When the motor/engine is across the frame/chassis this is called a TRANSVERSE motor.Cylinder arrangement is not in the description of how the motor/engine ...
Cutaway side-view diagram of an axial piston pump 3-D rendering of an axial piston pump with the parts labeled Animation of an axial piston pump in operation. An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel.
