New Mahle piston ring coating for high-output GTDI engines; chromium nitride using high-velocity oxygen fuel process

Green Car Congress

Mahle has developed a new thermal spray coating for modern high-output direct-injection turbocharged gasoline engines (GTDI). Under development since 2011 at Mahle’s thermal spray development labs in Michigan, the new process initially was designed for high-output GTDI engines currently in production by two US domestic automakers.

ETH Zürich Developing Pneumatic Hybrid Engine; Approaches Hybrid-Electric Performance at Lower Cost

Green Car Congress

Pneumatic hybrid engine on the test bench. Researchers at ETH Zürich are developing a pneumatic hybrid engine—an internal combustion engine connected to a compressed air tank instead of a battery system. If fuel is also injected, the engine responds quickly. The compressed air supply also allows extreme downsizing.

gasoline and diesel) represent the bulk of energy consumption throughout the forecast period. However, Navigant foresees that the consumption of gasoline will slowly decrease as alternatives and diesel become more popular in light-duty vehicle (LDV) segments. Electricity and hydrogen will together account for less than 0.5%
