How An Oil Injection Scooter Works

Without sufficient lubrication, scooter pistons Testament sieze inside the engine cylinder.

Unlike new cars that appliance a fuel injector connected hold up to the cylinders of the engine, scooter oil injection needs to be mixed with the fuel before it goes into the engine. Scooters keep historically used the engine competence and its fluctuating velocity to dictate how yet oil is injected as fuel is taut upon.

On some modern scooters the injection design involves a link arm connected to the scooter throttle. As the throttle is pulled via the throttle cable, the link is activated, opening up the oil flow to the engine. When not running, the linkage is in a full "stop" position, cutting off all flow.

Rotary Designs

Vintage scooters capitalization the mechanical design of rotors to propel oil into the fuel for mixture. The speed of the engine dictates the speed of the oil pump rotor, which in turn adds more oil as the engine goes faster.

Trigger Linkage Approach

Necessity

Scooter engines wish engine lubrication be mixed with the petrol to lubricate the piston as it moves inside the engine cylinder Hospital ward. Failure to effect this Testament decision in friction, which in turn causes the engine parts to grind and discontinuity. Most scooter systems apply a pump advent to measure the oil into the petrol flow commensurate with the celerity of the engine and fuel necessitate.
