This paper presents an experimental evaluation of the effect of air filter pressure drop on the
composition of exhaust gases and the operating parameters of a modern internal …

Differences between the results obtained in laboratory and road tests of vehicles depend on
a number of factors. Among the most important of these are driving cycle and road load …

Electromobility is developing rapidly in all areas of transportation, starting with small
personal vehicles and passenger cars through public transportation vehicles and ending …

The article presents a comparison of exhaust emission test results from a passenger car with
a spark-ignition engine examined with the WLTC (Worldwide Harmonized Light-Duty …

In this study, the authors assessed the road emissions of several passenger cars using
specialised instrumentation, of the PEMS type, to measure particle number emissions in real …

The subject of assessing exhaust emissions in real driving conditions has been relevant for
a long time. Its introduction into approval tests focused attention on the comparative …

Plug-in hybrid electric vehicles (PHEV) have the potential of combining the benefits of a
renewable electric mix with biofuels. More recently, PHEV have been designed to be …

The results of diagnostic tests under steady-state speed conditions of an unloaded engine
do not fully reflect the emissivity of vehicles adapted to run on natural gas. Therefore, it is …

Electrical vehicles have the ability to partially recover some kinetic energy during braking.
Kinetic energy is transformed into electric energy, which is fed to the battery by the control …
