Special Issue Information

Dear Colleagues,

The development of Internal Combustion Engines is driven by the regulatory framework, with worldwide tightened criteria for pollutant emission and fuel economy.

ICEs advances and trends are achieved through multiple paths, with interrelated research efforts aimed at enhancing the engine's key features.  

Strong efforts are concentrated on the use of alternative fuels, whether synthetic or natural, pure, or blended, to neutralize the environmental impact of the engine, both in terms of GHG emissions and in terms of pollutants. Novel combustion concepts, strategies, and their control encompassing the exhaust after treatment systems (ATS) are crucial to meet the regulation limits in the context of highly dynamic operating conditions.

The present Special Issue of Energies aims to gather innovative research and include some of the latest developments on internal combustion engines. More specifically, topics of interest for the Special Issue include (but are not limited to):

  • Alternative fuels (pure fluids and blends), additives, and lubricants for ICEs.
  • Injection system hydraulics and mechanics.
  • Novel concepts of combustion.
  • Pollutant formation and after treatment.
  • Future/novel concepts improving the efficiency of automotive, industrial, steady, and marine engines.
  • Future emission regulation and future exhaust gas analysis.

The use of renewable fuels for internal combustion engines marks a significant stride towards sustainability in transportation and power generation. Ensuring the compatibility of these fuels with existing diesel engines and infrastructure is paramount for a smooth transition. Diesel engines capable of harnessing the advantages of alternative fuels without extensive modifications offer a pragmatic approach to sustainable power for vehicles and industries. This article investigates the impact of carbon-neutral renewable fuel types (hydrogenated vegetable oils, or HVOs, and biodiesel) on the operation of a high-pressure injection pump, focusing on rotational speed and delivery pressure as key parameters. Our investigation, based on pump operating cycle analysis and volumetric efficiency measurements, aimed to investigate to what extent shaft speed and fuel type influence pump performance. Hydrogenated carbon-neutral fluids (HVOs) demonstrate adequate hydraulic capabilities compared to conventional fossil fuels. The findings underscore that while the fluids under consideration vary in viscosity and compressibility modulus, it is the compressibility modulus that predominantly affects the pump’s operation cycle. Diesel (fossil) fluid exhibits intermediate characteristics compared to hydrogenated fossil diesel fluids and biodiesel. The differences in terms of volumetric efficiency are finally reported, showing that hydrogenated carbon-neutral fluids do not significantly hinder the pump’s flow rate transfer capability.
