Diesel engine fuel injection systems

It is estimated that fuel costs represent as much as 50-60% of total ship operating costs, depending on the type of ship and service. If fuel injection systems are not operated correctly, it can lead to poor combustion, increased costs and damage to the environment. It is therefore essential that those responsible for operating diesel engines have a good understanding of fuel injection systems.

This title will describe the components and operation of a variety of common diesel engine fuel injection systems.
