The Stanadyne DB2 Distributor Pump for Medium Duty Diesels

The DB2 is a refinement of a design that has been in production for 27 years. Features have been recently developed to meet the unique requirements of passenger cars and light duty trucks. Because of legislated exhaust emissions standards that apply to these vehicles, control of timing and injection characteristics is critical. The DB2 incorporates modifications to precisely regulate these functions.

Considerable material describing injection pump mounting is presented to assist the engine designer.

DB2 applications include 2, 3, 4, 6 and 8 cylinder engines for maximum ratings of approximately 25 BHP/cylinder.
