In order to avoid the negative effects of increasing the amount of RME in the fuel, the nitrON® package was used, containing 3 different additives: stabilizing, washing and increasing the cetane number of the fuel. The tests were carried out with the use of the Caterpillar C27 engine of the 6Dg locomotive connected to a water resistor. The hourly engine fuel consumption (FC), NOx concentration and exhaust opacity were measured for 3 points of the F test, in accordance with UIC 624. The concentration of the nitrON® additive in the test fuel was 1500 ppm (v / v). For idling, the reduction in FC value was only 1.5% (in relation to the base fuel), but for a very high engine load and nominal rotational speed, the percentage reduction in FC was as high as 5%. The reduction of NOx concentration for idling (as a result of using nitrON®) was approx. 10%, while for high engine load, the percentage reduction of NOx concentration in the exhaust gas exceeded 15%.
