Progress and Prospects in Internal Combustion Engines
Ramin Barzegar, Ph.D.
Abstract. Internal combustion (IC) engines have proved to be very practical and useful power generation systems due to their high efficiency and considerable power to weight ratio and are widely used in many fields such as transportation, automotive industry, etc. However, the undesirable emissions from IC engines are of major concern because of their negative impact on air quality, human health, and global warming. Therefore, there is a pressing need to develop advanced combustion engines to maximize the energy efficiency and totally mitigate the exhaust emissions. In this regard, the hybrid electric engines seem to have a major share in the future transportation vehicles, because of their eco-friendliness and flexibility in operation. On the other hand, several studies have been conducted on improving the performance of conventional IC engine by using alternative fuels, without much modification in the engine system. Moreover, nonconversional IC engines such as dual-fuel, free-piston, gasoline direct injection, HCCI, lean-burn, and variable compression ratio engines are in research and development phase to address the need for high efficiency and low emission engines. This seminar aims to present the on-going research topics related to today’s progresses and future prospects in internal combustion engines.
