Development of the Bosch CP-3 Common Rail Pump for JP-8 Fuel
Development of the Bosch CP-3 Common Rail Pump for JP-8 Fuel. In Phase 1, tests showed that the CP-3 pump had high wear after only 500 hrs. of testing using JP-8 fuel. This wear is caused by the very low viscosity of the fuel, and the lack of effective anti-wear additives in the fuel. The primary problems identified are: (1) tappet wear, (2) plunger wear (contact button), (3) bearing cavitation, (4) Oldham drive wear, (5) fuel seal and shaft wear and (6) inlet valve and seat wear. The solution to these problems will include changes in basic design geometry, materials and heat treatment. Although our proposal will describe detailed design proposals, the final solutions will stem from engineering analysis. The project is divided into three separate phases: (1) Design, analysis and manufacture of a prototype and a 500 hr accelerated proof test. (2) Deficiencies will be corrected and a 2nd. prototype will be built and tested (500 hrs). (3) Any remaining problems will be corrected and a 3rd prototype will be built. This final prototype will be tested for 1000 hrs(with a 500 hr inspection)under accelerated test conditions. The pump will be inspected and a final report will be written.
