When crankshaft of diesel engine 42 rotates, bent axle driving wheel 52 is rotated with identical rotating speed, by the drive cam shaft of steel band 25
Driven pulley 51 rotates.The present invention can according to the rotating speed of bent axle driving wheel 52, the tach signal of camshaft driven wheel 51 and
Electric-controlled fuel injector A9, the tubing pressure signal of electric-controlled fuel injector B18 porch, determine how adjustment bent axle driving wheel 52, cam
" fuel feeding gearratio " between axle driven pulley 51, so as to solve that fuel feeding efficiency during 21 low-speed running of high-pressure oil pump is low, fuel feeding stabilization
Property poor, supply capability superfluous problem when running at high speed.
When 47 low-speed running of diesel engine, the rotating speed that crankshaft rotational speed sensor 32 measures crankshaft of diesel engine 42 is too low, cam
The rotating speed that shaft speed transducer 23 measures high-pressure oil pump camshaft 22 is too low；Tubing pressure sensors A 49, tubing pressure is passed simultaneously
Sensor B50 measure respectively electric-controlled fuel injector A9, electric-controlled fuel injector B18 inlet pressure it is too low, therefore controller 48 judge work as
Before " fuel feeding gearratio " it is less than normal, send increase " fuel feeding gearratio " instruction, crankshaft pulley A33, crankshaft pulley B34 receive control
The instruction of device 48, on electromagnet electricity, produce electromagnetic attraction, crankshaft pulley A33, crankshaft pulley B34 respectively in axial direction to the right, axially
To left movement, crankshaft pulley return spring 35 is compressed, and axial gap diminishes, and the pulley diameters contacted with steel band 25 become big.

Power, cam shaft pulley A24, cam shaft pulley B26 respectively in axial direction to the left, move right, cam shaft pulley return spring 27 is received
To stretching, greatly, the pulley diameters contacted with steel band 25 diminish for axial gap change, convex so when the rotation of bent axle driving wheel 52 is turned around
The multi-turn rotation of wheel shaft driven pulley 51.As steel band 25 and the contact diameter of bent axle driving wheel 52 become larger and camshaft is driven
The contact diameter of wheel 51 is tapered into, and " fuel feeding gearratio " gradually increases, until tubing pressure sensors A 49, tubing pressure is passed
Sensor B50 detects electric-controlled fuel injector A9, the inlet pressure of electric-controlled fuel injector B18 meets requirement.
When diesel engine 47 runs at high speed, the rotating speed that crankshaft rotational speed sensor 32 measures crankshaft of diesel engine 42 is too high, cam
The rotating speed that shaft speed transducer 23 measures high-pressure oil pump camshaft 22 is too high；Tubing pressure sensors A 49, tubing pressure is passed simultaneously
Sensor B50 measure respectively electric-controlled fuel injector A9, electric-controlled fuel injector B18 inlet pressure it is too high, therefore controller 48 judge work as
Before " fuel feeding gearratio " it is bigger than normal, send the instruction of reduction " fuel feeding gearratio ", crankshaft pulley A33, crankshaft pulley B34 receive control
The instruction of device processed 48, electricity on electromagnet, produces electromagnetic repulsion force, promote crankshaft pulley A33, crankshaft pulley B34 respectively in axial direction to
