Abstract

Presents results of a study of the output characteristics of the electric fuel pumps fuel system cars. A new method of diagnosing test. The paper deals with the study of the relationship of the technical condition of the pump, with its high-quality performance fuel system. It is determined that the control of technical condition of pumps can be carried out by measuring the difference between the values of the rotational speed of a crankshaft when switching off the sparks and fuel. Experimental results are presented of the dynamic method, which has the most informative and information capacity.
