For all diesel engines, at a fixed fuel setting, the amount of fuel delivered to the engine will increase as engine and pump speed increases. It must be controlled, or over-speeding of the engine will occur. The cetane rating of a diesel fuel defines how easily the fuel will ignite when it is injected into the cylinder. The lower a fuel's cetane rating, the longer it takes to reach ignition point. The fuel tank stores fuel away from the engine.
Baffles ensure the pick-up tube is always submerged in fuel.
This stops air entering the system. . Fuel Filters Fuel filters remove abrasive particles, and water. . A diaphragm-type lift pump can be mounted on the engine, or the injection pump. An eccentric on a camshaft pushes on a rocker arm. It acts on a diaphragm to create a pressure difference, which lifts fuel from the tank to the injection system. .
