You must thank Rudolf Diesel because the engine he invented in 1892 – patented on 23 February 1893 – has now been used widely in many types of vehicles, including car.

However, diesel engine is identical with rough vibration plus black smoke. This is deemed make acceptable by some people because more air supply to the engine cylinder – than in petrol engine – will result in harder explosion.

But if the vibration is exaggerated and the smoke exceeds the normal limit, you must be suspicious with your diesel car. Generally, that situation happens because the inaccurate timing/injection at the injector, inappropriate valve gap, dirty air filter, and so on. If this is the case, you had better take your car to your favorite garage.

The bottom line is that the service of diesel car is not different from that of petrol car. However, periodic checks of oil filter and air filter as well as lubricant refill are of the utmost importance. Please read the manual to know what kind of lubricant is most suitable for your car.

To minimize the smoke, automotive experts developed common-rail direct injection technology. This is because the particle of diesel oil is heavier than that of the petrolium. Thus, to improve the particle crushing process, the pressure of diesel oil into combustion chamber must be increased. Please note that engine using this kind of technology requires diesel oil with low sulphur.
