| 摘要 |
This disclosure deals with an aneroid for an internal combustion, compression-ignition engine including a turbocharger. The engine further includes a fuel supply system including a fuel supply rail connected to carry fuel to a plurality of fuel injectors and a regulator for regulating the pressure of the fuel in the supply rail. The quantity of fuel injected in each operating cycle of the engine is a function of the fuel pressure in the supply rail. The aneroid is connected in the rail between the regulator and the injectors, and it includes valve means operative to gradually increase the fuel pressure in the rail downstream of the aneroid, in response to a rise in manifold air pressure. The aneroid further includes means responsive to the downstream fuel pressure for adjusting the valve means to reduce the fuel pressure in response to a rise in the downstream fuel pressure.
