Injection Valve Fluid Supply Housing

Abstract

The EPA (Environmental Protection Agency) has been working on a new diesel fuel injector system to address performance and emission issues in clean Diesel engines. The new fuel injectors operate at pressures from 35,000 to 40,000 psi and are hydraulically actuated. The combination of an intensifier and a hydraulic pump will produce these high pressures. This project addresses the issue of how to connect the hydraulic pump to the actuator valve while eliminating leakage. This connector must be feasible for bench testing in a multiple cylinder scenario, and preferably will also be feasible for use within passenger car applications.
