Description of systems
Lubricant system
The oil is drawn from the wet sump through a coarse filter on the oil pickup tube to the oil pump.
From the pressure side of the pump, the oil passes the oil cooler (optional) and oil filter, after
which it enters the main oil gallery to flow to various points of lubrication in the engine. The surplus
oil emerging from the points of lubrication accumulates back into the wet sump on the bottom of
the engine.
Note: The oil pump unit is equipped with an integrated pressure release valve limiting the
pressure at cold starts or in the event of blocked oil lines.
Note: A pressure sensor should be installed to measure the pressure in the oil gallery, while a
temperature sensor should be installed to measure the oil temperature in the oil sump.
Fuel system
Fuel flows from the tank through a coarse filter to the electrical fuel pump. From the pressure side
of the pump it passes through a fine filter, on to the injectors and integrated pressure regulator,
after which it returns to the fuel tank and suction side of the fuel system.
Note: The constant flow and pressure helps eliminate the possibility of a vapour lock within the
fuel line circuit.
Note: The fuel pressure regulator causes a 3 bar pressure difference between the pressure in the
fuel lines and the varying pressure in the inlet manifold causing a constant pressure flow
through the injectors.
