Fault analysis of the combustion engine used in public transport vehicles

The goal of this article is the fault analysis of combustion engines on the basis of the assessment of dependent variables: initial mileage, annual mileage and the annual number of orders made in the service and repair system compared with the independent factor, i.e. bus make. In the research four vehicle makes were tested: Jelcz M121, Mercedes-Benz Citaro, Solaris Urbino 12 and Autosan Sancity 12LF. The research encompassed the number of faults of a vehicle and its systems, the initial and annual mileage. It was conducted on the basis of 2015 data broken into particular months.
