A Procedure for the Specification of Distributor Pumps for High Volume Production 690602

The C.A.V. D.P.A. distributor pump has been developed over the past 15 years by C.A.V. to meet the need of the European diesel industry for a preset pump suitable for high volume engine production. The procedure for arriving at F.I.E. specifications, starting with initial trials and working through to final production rehearsal, is described in this paper. A “master pump” system is used for monitoring and controlling production fuel levels. Among other factors brought out in the paper are delivery curve shape control, choice of advance curve and its influence on smoke, efficiency, and cylinder pressures.
