Fuel Injection Pumps Diesel - Cummins, Duramax, Powerstroke

Gasoline and Diesel vehicles differ greatly in the way that their fuel is injected. Fuel injected vehicles use a more indirect route to inject the gasoline than ones which use the superior direct injection method. Fuel Injected vehicles have a number of inefficiencies in burning their fuel, which causes usable energy to be wasted, decreasing the value of the gasoline you purchase. Direct injection engines skip the waiting period that fuel spends in standard engines, shooting it straight into the combustion chamber. This facilitates the even and more efficient burning of the fuel. It is actually squirted RIGHT into where the combustion chamber is at its hottest, creating a better burn. This translates to increased gas mileage and more power provided to the wheels. Diesel engines use more air in their fuel/air mixture, which leads to a more conservative burn of fuel.

    Fuel Injection Pumps: Variations and Direct Injection

    Diesel Direct Injection Pumps are always composed of fuel injectors (at least one designated per cylinder), and a chamber for combustion. This chamber is basically a housing unit that is designed to hold the top portion of each cylinder. Different direct injection systems can also possess a common rail system, distributor and inline pump system, or unit direct system. Common rail systems use a long metal cylinder which is known as a fuel rail in order to spread fuel to each injector at pressure levels that are very high. Distributor and inline pump systems utilize a wheel distributor or plunger style pump in order to force pressurized fuel directly to the injectors. The unit direct system uses an injector and a fuel pump fused to it as a single unit directly over each cylinder. The part of the car’s computer which manages fuel dispersement in a direct injection system must think much more rapidly than it does for a normal fuel injection system. These upgrades are especially effective when combined with the perquisites of a turbo charger, providing an immense boost in fuel efficiency.
