Compression-ignition engine fuelled with diesel and hydrogen engine acceleration proces

Longwic Rafał, Woźniak Gracjana, Sander Przemysław

Combustion Engines

2020

R. 59, nr 1

47--51

The paper presents the results of research consisting in acceleration of a diesel engine powered by diesel and hydrogen. The test stand included a diesel engine 1.3 Multijet, hydrogen cylinders and measuring equipment. Empirical tests included engine testing at idle and at specified speeds on a chassis dynamometer, vehicle acceleration in selected gears from specified initial values of engine revolutions was also tested.. Selected parameters of the diesel fuel combustion and injection process were calculated and analyzed. The paper is a preliminary attempt to determine the possibility of co-power supply to diesel and hydrogen engines.

Experimental study on comparison of kinematic traffic characteristics of a road tractor and a passenger car at sub-zero temperatures

2013

Vol. 6, iss. 4

37--41

Experimental studies on kinematic characteristics of the vehicle are usually performed using passenger cars, which is related to their availability and the ability to conduct tests on public roads. Road tests using trucks, due to the increased need for security, are performed less frequently and usually on special routes or public roads temporarily excluded from the traffic. The lack of tests performed together on various types of vehicles in similar environmental and weather conditions limits the possibility of direct comparison of the obtained results. Road tests conducted in December 2012 enabled the acquisition and recording of longitudinal acceleration values of passenger car and truck under identified environmental and surface conditions. Experimental studies were conducted on kinematic characteristics of the vehicle and a comparative analysis of the intensity of acceleration and breaking of a new passenger car and of a truck tractor without a trailer in sub-zero temperatures was carried out.
