The scope for improving the efficiency and environmental impact of internal combustion engines
Overview
Paper Summary
Internal combustion engines (ICEs) still have significant potential for efficiency improvements and emissions reductions, potentially exceeding diesel-like efficiencies in the medium term with technologies like gasoline compression ignition (GCI). Combined with other strategies like hybridisation and lightweighting, fuel consumption in light-duty vehicles could be reduced by 50% compared to the current average, while exhaust pollutants can be controlled to levels well below current legislation.
Explain Like I'm Five
Scientists found that even regular car engines can be made much better. They could use way less gas and make far less pollution, especially when cars are also made lighter or have electric parts.
