Common rail diesel tractor engine performance running on pure plant oil

- A study on raw rapeseed oil (PPO) and its performance in a common rail diesel engine.
- The torque and power drop is a direct consequence of the oil's lower energy content.
- The overall fuel consumption, as well as the engine energy efficiency, is comparable to diesel.
- A power drop of 12-14% was observed in the engine fueled with PPO as opposed to the one fueled with diesel.
- The alternate fuel had no impact on the energy efficiency.
