| 摘要 |
This invention relates to a fuel injection system and to a fuel pressure regulator therefor. A fuel injection system, for injecting pressurised fuel into an inlet duct or manifold of an engine includes a fuel-flow metering orifice which is fed with the pressurised fuel and which is exposed on its downstream side to the pressure obtaining in the inlet duct or manifold, and a fuel pressure regulator is arranged to regulate the fuel to a pressure which exceeds the inlet duct pressure by an amount which increases with increasing inlet duct absolute pressure. |
