Evolution of a Rotary Distributor Pump to Satisfy Off-Highway Emissions Regulations

The development of emission regulation proposals for off-highway engines presented a significant challenge to the design of the fuel injection systems.

The DP200 range of pumps was evolved from the DPA to meet this need. It incorporates a number of enhancements that will enable emissions compliance.

The paper will describe the operation of the new pump systems and show the results of their use on engines. Future evolution of the pump to meet the next round of emissions control and the use of electronics in off-highway markets will be discussed.
