Abstract
This paper reports upon noise measurements with a truck diesel engine and its in-line injection pump. The measurements are carried out in anechoic chambers.
The most important noise sources of the pump and the diesel engine are shown. Some noise decreasing influences on the injection pump are explored.
The flange joint of pump and crankcase builds a bridge for bodily-vibrations in both directions. Thus, the airborne noise emitted from the pumphousing is, on this engine which has been tested, primarily due to bodily vibrations transmitted from the crankcase to the pump.
