At full loading in the power supply system there is большее quantity of fuel, than what is injected into combustion chambers. Atomizers also inject not all fuel into the combustion chamber, superfluous fuel serves for greasing and cooling of mobile parts of the pump of a high pressure and atomizers.
Engine Endura-DI has one more function which does not suppose work of system of injection without fuel or work dry: as soon as the fuel stock becomes less than two percent, block RSM switches off the fuel pump. Atomizers have the union, connected with returnable топливопроводом on which surpluses of fuel come back back in a fuel tank.
