Colt “PRS” - The Versatile Distributor Type Diesel Injection Pump 700699

A new heavy duty distributor type diesel fuel injection pump known as type “PRS” has been developed by S.I.G.M.A. in France.
Retaining many of the advantages of “in-line” type injection pumps, the “PRS” has exceptional flexibility of application. At the same time, it is simple, compact, lightweight, and durable. This has been achieved principally by the use of a spill metering system which permits wide variation of the high pressure hydraulic characteristics.
The “PRS” is now in quantity production in Europe for engines ranging up to 8 cylinders and 310 bhp. It is also original equipment on one American engine, and application programs are proceeding satisfactorily towards production in the U.S.A. for installation on additional engines.
