The most significant improvement offered by the Concept IC Engine:

·         The most significance of IC engine in Day to day life, It is a lightweight and reasonably compact way to get power from fuel.

·         It is also significantly safer and more efficient than the engine it replaced – steam.

·         Small, lightweight IC engines made personal transportation possible. It transformed how we built cities and did business.
