liter Isuzu diesel engine, demonstrates a 35% fuel efficiency improvement over traditional vehicles in the FedEx Express fleet. This conversion not only reduces fuel consumption and emissions, but will also extend the engine life in fleet vehicles by supplementing the necessary power with their hybrid-electric drive train.

A study by researchers at The Hong Kong Polytechnic University and Tianjin University has found that the use of fumigation ethanol in a 4-cylinder diesel decreases NO x , smoke and particulate mass and number concentrations. However, there is lack of investigation on the particulate emissions on mass or number concentration.
