Lean-burn is an effective way to improve thermal efficiency and reduce emissions of spark-
ignition (SI) engines. A hydrogen (H 2) enrichment combustion strategy can extend the lean …

Currently, alternative energy sources such as hydrogen and alcohol are increasingly used in
IC engines. There is a gap in the literature of both experimental and numerical studies …

Performance and emissions of a direct-injection (DI) spark-ignition engine with high
compression-ratio (15.5: 1) fed with hydrogen, hydrogen-rich reformate, and methane are …

Storing excess wind and solar energy in the form of hydrogen injected into the natural gas
grid is one of the main ingredients of the energy transition. This hydrogen injection has an …

The approach of fossil fuel substitution requires alternative strategies in the progressing
sector coupling of energy storage, distribution and conversion. Promising solutions are …

Knock combustion is one of the primary factors limiting thermal efficiency improvement in
spark ignition (SI) engines. After a century of research, scholars have made significant …

Considering the current environmental restrictions, particularly those imposed on fossil fuel
exploitation, hydrogen stands out as a very promising alternative for the power and …

Due to the elongated shape of the combustion chamber and strong one-way flow
characteristic, changing the location of enhanced combustion is an effective means to …

With increasingly stringent emission regulations, marine natural gas engines need to
improve their performance. Various proven advantages of hydrogen-natural gas (H-NG) …

Most of the power plants in the world are based on gas turbines and many researchers tried
to improve their efficiencies. This goal can be attained by the optimum utilization of heat …
