Internal Combustion Engines: Not Dead Yet! Still Room for Efficiency and Emissions Improvements

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.

Possible Conflicts of Interest

None identified

Identified Limitations

Reliance on Projections
The reliance on projections and estimates for future trends introduces uncertainty into the analysis.
Limited Scope
The focus on technological solutions overlooks the importance of behavioral changes and policy interventions.
Unfair Comparison
The comparison between different technologies may not be entirely fair due to varying levels of maturity and development.

Rating Explanation

This paper provides a comprehensive overview of the current state and future potential of internal combustion engines, highlighting the significant scope for improving their efficiency and reducing their environmental impact. The analysis is well-structured and supported by data, although there is some reliance on projections and estimates. The discussion of various technologies and their implications is insightful and balanced. Overall, this is a strong and valuable contribution to the field.
