The driveline is particularly important. Currently, there is a choice of possible driveline systems for a truck, but the conventional internal combustion engine is still the dominant solution. The article describes the driving characteristics of a city truck, in particular the operation of an internal combustion engine in such a truck. On the basis of data collected from several garbage trucks equipped with a compression ignition engine and compression ignition engines powered by CNG, an analysis of the load structure and engine rotational speed was presented. These vehicles operate in urban conditions and perform specific tasks. The data shows how ineffective the operation of an internal combustion engine is when operating a truck in a large city and in specific areas, e.g. a port. The reason is the very low load at low engine speed which dominates the performance characteristics of the truck. The analysis provides arguments that there is a need to change the way they are powered trucks, there is a need to replace the powertrain based on an internal combustion engine with a more efficient one.}, doi = {10.12716/1001.15.04.25}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Urban Area, Internal Combustion Engine, Garbage Truck, Garbage Truck Operation, City Truck, Compressed Natural Gas (CNG), Compression Ignition Engine, Powertrain} }
