【Abstract】 High pressure common rail fuel injection system is the most advanced injection system, and high pressure pump is one of the key components. Two kinds of typical pumps equipped with Bosch CR system and Denso ECD-U2 system are briefly introduced in this paper. Their principles are separately analyzed. The experimental study on a new pump is described in detail, and its characteristics are summarized.更多还原
