Diesel fuel not only functions as a trigger of combustion in the engine. Fluids consumed diesel engine also contains a substance that serves as a lubricant. Lubrication is very useful for components such as injection pump (supply pump) and injector (nozzle).


Poor quality of diesel fuel and the lack of substance in general lubrication can cause damage to the injection pump. Especially, the damage that resulted in the leakage of fuel pressure. Just a little leak can affect the duties of injection pumps in diesel fuel to produce high pressure (100-200 kg/cm2 for conventional injection pump). This is where the important role of lubrication of diesel, namely: to lubricate the injection pump is very precise construction.

Unfortunately, the information in the mass media had no mention that in some cases, the quality of diesel fuel in Indonesia is less good. Many drivers of anxiety when they consume diesel fuel can damage the engines of their cars.

Technically, automotive manufacturers have also actually help reduce the risk of possible entry of poor quality of diesel fuel. Before flowing into the pump diesel injection, there are components called sendimenter water and fuel filter which separates dirt and duty of water on the solar elements. This component served as the protector of injection pump.

Therefore, fuel filter and water filter sendimenter can only dirt, water or wax (candles). There are still substances other destroyer who escaped from the fuel filter. But, this function is very helpful and can be indicators of the quality of diesel fuel that we buy. If the fuel filter relatively quickly clogged or dirty at all, might be expected that the quality of diesel fuel that we buy less good.


Therefore, to help care for injection pump, do not forget to check the fuel filter regularly. Typically, the workshop suggested the replacement of the pump injection every multiple of 20.000 km. There’s even motorists who change the fuel filter every 10,000 km.
