The silencer (205) comprises internal from the EMS203 control signal, and extends to the engine cylinder and oil quantity adjusting.

A position sensor 213 detection throttle opening.

TMS201 and EMS203 of the cylinder is one or more of processors control program respectively, and capable of the programming end of the bracket on the invention embodiments to the pre-set sequence each stage method thereof.

Radiator is 1 to mark to act according to the invention embodiments the engine hydraulic to reduce the control method of the flow pattern. The reference diagram 1, wherein the detailed description is as follows a rubber according to the invention embodiments the engine hydraulic reducing control method thereof.

The first, wherein the S11, EMS203 judgment whether the torque the reducing signal carrier of TMS201.

Around the field of normal technical personnel, obviously, TMS201 according to at least one shift control with a determine whether the needs engine of reducing controller, a shift control with a turbine can be (rpm) and a turbine torque, and a transmission speed output shaft of the rotating speed).

The clamping S11 determined when the TMS201 of the torque reducing signal carrier, EMS203 of the limitation S12 the throttle opening whether is larger than the preset throttle opening.

The preset throttle opening preferably device is 5% mm, while the field of normal technical personnel of revise comprising a values. Driving the preset throttle opening (i.e. 5%) is an idling a throttle opening.

The throttle opening of the S12 is larger than the preset throttle opening is 5%, the adhesion screw S13, the EMS203 body of engine with the control in turn to reduce the torque engine.

The engine body of reducing controller, 211 TMS201 performing the hydraulic controller through the control hydraulic control module.

The throttle opening of the S12 is not greater than the preset throttle opening, wherein the S14, EMS203 judgment engine ignition timing ahead of a time whether exists.

EMS203 of according to the air inlet temperature, the cooling temperature and a first-level determine of engine ignition timing ahead of a time whether exists.

The infinite around the technical field normal technical personnel, the engine ignition timing the position is obvious ahead of time, a therefore to abbreviate wherein further explanation.

Plurality of the S14 plug the engine ignition timing the position exists ahead of time, wherein the S15, 211 TMS201 performing the hydraulic controller through the control hydraulic control module, which do not need to carry out of the engine hydraulic to reduce the control. Therefore, a avoid the torque requesting reducing and ignition timing requests ahead side of the conflict.

The case; one end of the engine hydraulic to reduce the control the existing technology likely hole, the TMS201 torque reducing the carrier is hinged with the engine ignition timing the position to conflict ahead of time.

The infinite around the technical field normal technical personnel; the hydraulic control of the S15 is obvious, a therefore abbreviate to the bolt.

On the other side, if the inner S14 plug the engine ignition timing the position of the exist ahead of time hole, EMS203 end of the engine hydraulic reducing controller is further S13.

Because of the shell EMS203 with the determined ignition timing the position to exist ahead of time, therefore the torque reducing the carrier and ignition timing requested ahead side of the upper moving sealing.
