Summary:

This paper deals with some discharge characteristics of a fuel injection system intended primarily for high speed service. The system consisted of a cam actuated fuel pump, a spring loaded automatic injection valve and connecting tube. The pump was provided with two ball inlet valves, but no discharge valves, and was operated at speeds from 600 to 1800 R.P.M. The data were taken by spraying on blackened paper attached to the side of the flywheel rim. Patterns were thus formed on the paper, a single record pattern being the result of a number of discharges. From oscilloscope observations, it is believed that the discharges during each run were fairly uniform.

The spray patterns showed the beginning of discharge to be definite while the end was drawn out and somewhat indefinite. For any given R.P.M. the lag of the jet was nearly constant for different lengths of plunger stroke. Discharge continued for a considerable interval after the plunger stroke was completed.
