ROAD PROPERTIES SURVEY OF HIGH VOLTAGE PUMP NP-VE 4/9F2400RND340 USED IN DIESEL ENGINES

Abstract

This paper presents the results of the evaluation characteristic line of injection pump NP-VE 4/9F2400RND340 used on diesel engines. The experiment is carried out to test experimental measurements fuel supply of high-pressure pump NP-VE 4/9F2400RND340 on the dynamometer by Bosch in various modes. The result imitate on characteristic lines drawing fuel supplies in the hand position and size different rotation frequency. On this basis, assess generalized characteristic lines built compared with the theoretical basis. This result is the basis for integrated analysis and assessment of the state of technical specifications to cater for diagnostic purposes.
