Tailored solutions for flexible use of fuel
With the higher technical performance levels of the injection systems, the demands placed on the fuel in terms of purity and quality also rise. Thus the fuel must comply with pre-defined values for viscosity and lubricity, as components of the highpressure
pumps and injectors are lubricated by the fuel. It must also be free of any contam-ination that would lead to abrasive damage at the high pressures employed. To ensure that the engine operates correctly, therefore, only diesel fuel that is approved for the application in question and meets the applicable standard may be used. At the customer’s request, mtu
carries out analyses for specific application-related approval of other fuels in close cooperation with Rolls-Royce Power Systems brand L’Orange or alternative suppliers. With some applications, for example, a lack of lubricating
properties on the part of the fuel can be compensated for by special coatings on the injection system. In addition, mtu
assists customers when designing the onsite tank and fuel system. This is of great interest for mining vehicles, for instance, that are subjected to high levels of dust exposure.
continually develops its engines to ensure they will meet the tough future emissions standards, while at the same time consuming as little fuel as possible. To this end, mtu
optimizes fuel combustion in the cylinder by means of its electronically controlled common rail fuel injection system in combination with other technologies such as exhaust gas recirculation. By achieving clean and efficient combustion, the expense of exhaust aftertreatment systems can be minimized and, in some cases, eliminated altogether. mtu
has used common rail systems success fully since as long ago as 1996 and has continually advanced the technology in collaboration with Rolls-Royce Power Systems brand L’Orange and other suppliers. Due to its extensive expertise in common rail injec -tion systems, mtu
is able to optimally exploit the potential of the technology in order to make engines extremely economical and clean.
