Internal Combustion Engine Performance

The present Special Issue of Energies provides innovative research and includes some of the latest developments on internal combustion engines. Among these topics, special attention has been given to aspects related to combustion mechanisms in spark and compression ignition engines, pollutants formation (particulate matter, NOx, CO, HC, noise), exhaust after-treatment systems, internal measures for emission control (EGR and water injection), exhaust heat recuperation systems, and other special problems associated with the current status of internal combustion engine research and development.
