ADVANCEMENT IN INTERNAL COMBUSTION ENGINES

Abstract: Over the years, there have been continuous advancements in the design of internal combustion engines. In particular, the vision behind the evolution of these engines was to ensure a minimum power extraction from the fuel while reducing the emissions and pollution to the environment. The main areas of advancements were in the engine design, the timing controls, fuel injection, combustion and material selection [1]. With the recent technological advancements, the current engine designs are fuel efficient, and produce much fewer emissions.

Keywords: Scavenging: remove (combustion products), Supercharger: increase the density of air, Turbocharger: Provides extra air to the combustion chamber.
