摘要：
Fuel pressure in a deadheaded fuel rail (16) is regulated by an eddy current clutch (36) that forms part of the mechanism that mechanically couples the engine crankshaft (12) with a fuel pump (26) which delivers pressurized fuel to the rail. An electric control (34) that receives several inputs, including engine speed and fuel rail pressure, controls the degree of coupling that is provided by the clutch (36) so that the pressure is regulated even though the engine speed and fuel demand change during normal engine operation.
