This session explores advances in the creation of sustainable energy sources and their usage in the transportation sector. Topics can include research and in-production technology used to produce renewable energy sources and materials. A discussion on lifecycle analysis of the energy sources is also highly recommended. The SDPC encourages usage of papers, presentations, and panels in this session to display leading edge technologies and practical tools for engineers.

Event
This session focuses on fuel injection, combustion, controls, performance and emissions of SI engines fueled with gaseous fuels such as methane, natural gas (NG), biogas, producer gas, coke oven gas, hydrogen, or hydrogen-NG blends. Papers on Diesel-NG or diesel-hydrogen dual-fuel engines will also be accepted in this session.

Event
Mixed modes with both flame propagation and slow auto ignition. Distinct from SI knock: autoignition is desired and will not ruin the engine. Papers describing experiments and test data, simulation results focused on applications, fuel/additive effects, and SACI mode change are invited and will be placed in appropriate sub-sessions. Papers with an emphasis on the modeling aspects of combustion are encouraged to be submitted into PFL 110 or PFL120 modeling sessions.

Turbocharging is already a key part of heavy duty diesel engine technology. However, the need to meet emissions regulations is rapidly driving the use of turbo diesel and turbo gasoline engines for passenger vehicles. Turbocharged diesel engines improve the fuel economy of baseline gasoline engine powered passenger vehicles by 30-50%. Turbocharging is critical for diesel engine performance and for emissions control through a well designed exhaust gas recirculation (EGR) system. In gasoline engines, turbocharging enables downsizing which improves fuel economy by 5-20%.

Homogeneous Charge Compression Ignition (HCCI) combustion have attracted much attention as a high efficiency and clean combustion system. However, it is difficult to control the ignition timing because there are no a physical means of ignition. In addition, it is difficult to expand the operating range due to the occurrence of misfiring at low loads and the occurrence of rapid combustion (HCCI knocking) accompanied by in-cylinder pressure oscillations at high loads. Therefore, it is important to reduce the pressure oscillations of HCCI combustion knocking for expanding the operating range to the high load region. This study focused on the rapid combustion in HCCI. A primary reference fuel (0 RON) was used as the test fuel. The influence of external exhaust gas recirculation (cooled EGR) on HCCI knocking was investigated. HCCI combustion flame behavior with pressure oscillations were visualized by using a two-stroke engine that allowed visualization of the entire bore area.
