Special Issue Information
Dear Colleagues,
The internal combustion (I.C.) engine is one of the most important and successful technological developments of the last century. Its application during all these years until today has influenced essentially almost every aspect of human life used as the prime mover in land, sea and air transportation; as the source of electrical power production or as an emergency safety installation in a hospital or in a factory.
The main reasons for this enormous distribution and success is the high energy density of liquid hydrocarbon fuels combined with the ability of the I.C. engine to efficiently cover the whole area of energy demand from a fraction of a W to several dozen MW.
The world energy crisis and environmental impact have played major roles in the development of the internal combustion engine during the last decades. During these years, it became obvious that a closer understanding of the thermodynamic processes occurring within the engine was necessary. As a result, research on I.C. engines has enormously expanded, both on simulation and experimental bases. Nowadays, the main objectives are the improvement of engine performance, the minimization of fuel consumption/CO2 emissions and the reduction in the level of exhaust pollutants. To this aim, various alternative combustion techniques have been developed or are under development (e.g., direct injection SI engines, HCCI operation, etc.), and in parallel, various internal and after-treatment exhaust measures are also being examined.
The present Special Issue of Energies entitled “Internal Combustion Engine Performance 2026” under the present Guest Editor team has already completed five years of successful presence in this journal. During this period, many interesting papers of high quality have been published in the Special Issue. This is actual proof that, despite the difficult times and speculation around this type of energy production, combustion engines are present and alive; they are under continuous improvement and still play a dominant role in the energy market.
In this context, the 2026 issue of “Internal Combustion Engine Performance” aims to gather further innovative research and include important developments in the field on internal combustion engines.
More specifically, topics of interest for the Special Issue include (but are not limited to) the following:
- Combustion mechanisms in spark and compression ignition engines;
- Fuel injection and spray formation;
- Pollutants formation (particulate matter, NOx, CO, HC, noise);
- Exhaust after-treatment systems (three-way catalysts, oxidation catalysts, diesel and gasoline particulate filters, SCR, NOx adsorbers);
- Internal measures for emission control (EGR, water injection, etc.);
- Exhaust heat recuperation systems (Rankine cycle, turbo-compounds, etc.);
- Engine downsizing;
- Effects on engine structure and design due to increased performance demands;
- Special problems associated with large scale two-stroke engines performance and emission reduction;
- Alternative fuels’ and biofuels’ effects on engine performance and emissions (ethanol, butanol, biodiesel, etc.);
- Recent advances in internal combustion engines experimentation;
- Novel combustion systems (HCCI, PCCI and RCCI);
- Marine engine performance and emission reduction systems development.
