Diesel engines are used in a range of applications, from passenger vehicles to large scale transportation and shipping. The addition of a turbocharger dramatically increases engine performance and efficiency. Even these devices, however, have their drawbacks. The introduction of a turbine in the exhaust stream creates a restriction that impedes the engine's power. This limits the real-world efficiency and performance. These engines typically have an efficiency of ~40%. This project designed a system that recaptures heat wasted in the exhaust and uses it as the heat source for a Rankine cycle that powers the turbocharger. This system aims to improve overall engine efficiency, by reducing the flow restriction in the exhaust stream and the amount of energy wasted as heat through the exhaust.
