Future Fuel Injection System Requirements of Diesel Engines for Mobile Power

The diesel engine appears destined to play a major role in the mobile power field, through the next decade. In order for this engine to fully realize its superior potential in this field, considerable development work is being conducted throughout the world to optimize each subsystem of the engine. Through this work, the need for a new generation fuel injection system has become apparent.

This new system must be based on the latest technology available to provide a cost-effective design with increased capability. It can then provide the flexibility necessary to maximize the thermal efficiency of the engine while minimizing to a socially acceptable level the gaseous emissions, black smoke, noise and odor-irritant emissions of the next generation of diesel engines. Much of the information presented here is based on experience obtained from engines equipped with research type fuel injection systems. It should be considered an interim report, but work to describe an advanced injection system must begin now, to hasten the date of production availability.

It is the goal of this paper that these specifications serve as initial guidelines in the development of advanced fuel systems for the next generation diesel engines which are being designed to meet the demanding requirements of mobile power for the future.
