Air density increases as its pressure increases and as its temperature is reduced. To get the maximum benefit from a turbocharger an intercooler, or aftercooler,…
Turbochargers are driven by the exhaust gases and force more air into the cylinders, resulting in higher engine output. Naturally aspirated engines rely on atmospheric…
To change the air filter on this engine, first unclip the cover then remove the filter. Wash it in soapy water, and dry thoroughly before…
Fuel, even direct from the supplier, is never completely free of impurities. All fuels and lubricating oils are contaminated to some degree. Manufacturers supply fuels…
The fuel tank shut-off valve should be as close as possible to the tank, and outside the engine compartment in case it needs to be…
Most diesel engines need a cold starting aid. In some cases extra fuel is injected directly into the combustion chamber, which has the effect of…
Injectors work like a relief valve. The internal piston is spring loaded, remaining closed as pressure builds and opening when the set pressure (break setting)…
Fuel is considered to be incompressible. When it is pumped into a closed system the pressure rises rapidly until the break setting of the injector…
After changing the filter element, the fuel system must be bled to remove any air. First identify, then open the bleed screw on the filter…
The final line of defence for the high pressure pump is the fine filter, which traps any debris before it can clog either pump or…
