It is foreseen that in the near future in Estonia there will be growth in the consumption of alternative liquid fuels in internal combustion engines. The main share of it will be formed by the local raw material based diesel fuel and ethanol. In connection with this, the choice of fuels and the variety of their qualitative characteristics in filling stations will grow. This kind of situation will give rise to the necessity of creating new quality assessment methods which should be reliable, efficient and economical. There may be several assessment methods for taking fuel samples. Drivers consider the fuel quality assessment express methods especially valuable. Working out a new method like that is at present also supported by the electronic control system of the engine and the use of digital diagnostic devices. Creating and implementing the fuel quality assessment express method requires a considerable amount of effort. It includes the evaluation and prognosis of the fuels physical and chemical parameters, designing the simulation models of the engine combustion process pressure and temperature and carrying out the control testing.
