ENGINE AND CONTROL METHOD THEREOF
Document Type and Number:
Japanese Patent JP2017101560
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an engine which suppresses a variation of a suction intake amount which is caused when a part of intake air is compressed by an air compressor, in the engine which accumulates pressure in an air tank by compressing a part of the intake air by an air compressor when inside pressure is lower than a lower limit value according to an operation state of an unloader valve which operates according to the inside pressure of the air tank, and on the other hand, when the inside pressure exceeds an upper limit value, stops a compression function of the air compressor, and a control method of the engine.SOLUTION: An engine 10 comprises: a pressure sensor 41 as a detection device which detects an operation state of an unloader valve 35; and a control device 42 which monitors the pressure sensor 41, and performs correction on a calculation value at control for adjusting a suction intake amount Q5 when the unloader valve 35 is operated so as to introduce compression intake air A3 into an air compressor 33, and a part of the intake air is compressed by the air compressor 33.SELECTED DRAWING: Figure 3
