A fully variable valve train significantly increases the degree of freedom of the control of
internal combustion engines. Cylinder deactivation, thermal management, alternative …

Experimental studies of vibrations of asynchronous electric motors (EMs) of the electric bus
traction electric drive are carried out in the paper. The presented studies are based on …

The electric motor (EM) is one of the main components of any system. The EM quality is set
at the design and manufacturing stages, and its technical condition is maintained during …

When operating a hybrid vehicle (HEV), it is important to reduce maintenance and repair
costs. The HEV electric drive (ED) consists of electronic, electrical and mechanical parts and …

Spark-ignited internal combustion engines are known to exhibit a decreased brake
efficiency in part-load operation. Similarly to cylinder deactivation, the x-stroke operation …

In this paper is presented a simulation model of the electric drive (ED) system for the
diagnosis of an electric vehicle. Model is built by the method of spectral analysis of the …
