There are two main ways to measure diesel engine efficiency. The combustion process releases energy and a fraction of that energy is converted into useful work. The process can also be termed thermodynamic efficiency and is based on the details of the Otto or Diesel cycles. In either case, any energy that is not converted to mechanical work is...

To maximize diesel engine efficiency, it is crucial to know how to optimize the fuel mixture for your vehicle. Increased intake gas pressure improves combustion efficiency and indicated thermal efficiency. Reduced intake oxygen concentration does not improve the thermal efficiency significantly. Increased exhaust gas pressure, on the other hand,...

In order to get the most out of your diesel engine, it is important to understand the process by which energy is converted from fuel to usable work. This process involves a number of losses, including the chemical energy lost in emissions, the heat and friction generated during the combustion process, and losses due to the air, water, and other...
