Abstract

The invention provides a control device of a gas engine, wherein the engine drive has a vehicle of initiative noise suppression device which produces the vibration opposite to the noise in the carriage to suppress the noise. The engine is provided with a plurality of cylinders and cylinder stop mechanisms which switch between the operation of all cylinders making the plurality of cylinders work and the operation of part cylinders making the part cylinders stop work. According to the control device, the operating parameter of the vehicle including the operating parameter of the engine is detected. In the operating area of part cylinders corresponding to the detected operating parameter, the operating order of part cylinders is sent to the cylinder stop mechanism. Besides, the exception of the initiative noise suppression device is detected and the operating area of part cylinders is changed when the abnormality is detected.

Description

technical field [0001] The present invention relates to a control device for an internal combustion engine, in particular to a control device for an internal combustion engine that can be switched between the operation of some cylinders and the operation of all cylinders. Cylinder operation makes all cylinders work. Background technique [0002] Japanese Patent Publication No. 3-27406 discloses a control device for an internal combustion engine supported by an anti-vibration device that variably controls the vibration transmission rate. In this device, partial cylinder operation is performed by stopping fuel supply to some of the plurality of cylinders, and when partial cylinder operation is performed during idling operation, since the vibration increases, the anti-vibration device is controlled to reduce its vibration pass rate. [0003] In addition, JP-A-10-214119 discloses an active noise suppression device that suppresses noise in the cabin of a vehicle driven by an in...
