Ship Propulsion Train Efficiency Sensing
When comparing the energy present in the fuel burnt in the diesel engine with the output energy of the ship itself, approximately 70% is lost. Heat losses in the diesel engine are the main contributors to these energy losses, but there are also losses due to fouling and the ship environment. … Fetch Content
