Title:
内燃機関の制御システム及び圧縮天然ガスの不活性ガス濃度検出装置
Document Type and Number:
Japanese Patent JP5890214
Kind Code:
B2
Abstract:
In a control system that includes a pressure accumulating portion that supplies CNG to a fuel injection valve and a regulator that adjusts a pressure in the pressure accumulating portion to a set pressure and of which a valve element opens when CNG is supplied to the pressure accumulating portion and closes when supply of CNG to the pressure accumulating portion is shut off, a control parameter relating to a combustion state in an internal combustion engine is controlled on the basis of a length of a period during which an opening degree of the valve element reduces from a first predetermined opening degree to a second predetermined opening degree when the pressure in the pressure accumulating portion is adjusted to the set pressure by the regulator.
