Emission reduction has become an important subject of discussion in recent years, mostly
due to CO 2 emission limits set by the European Union to protect the environment. One of …

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

Cylinder deactivation is an effective measure to reduce the fuel consumption of internal
combustion engines. This paper deals with several practical aspects of switching from …

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 …

Featured Application The results obtained in the study can be applied in internal combustion
engines and power plants. Abstract The potential benefit of cylinder deactivation (CDA) on …

Besides defossilization, a continuous improvement of internal combustion engines is one
way to reduce the CO2 emissions of vehicles. For that, variability in the valve train …

Today's CI engines are subject to strict regulations of pollutant emissions and ambitious fuel
consumption targets. Therefore, the interaction between the engine and the exhaust …

In the process of cycle cylinder deactivation, the different proportion of cylinder deactivation
between adjacent working cycles will cause the problem of uneven operation of each …

In the pursuit of reducing carbon emissions and enhancing fuel efficiency, the integration of
advanced combustion technologies and alternative fuels in internal combustion engines …

Based on the self-developed hydraulic variable valve mechanism of four-cylinder engine,
this paper proposes a variable displacement valve control strategy based on the VOC-CDA …
