Title:
AUXILIARY CHAMBER TYPE GAS ENGINE
Document Type and Number:
Japanese Patent JP2018119485
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an auxiliary chamber type gas engine capable of supplying a proper amount of auxiliary chamber fuel to an auxiliary chamber even when an exhaust gas pressure changes.SOLUTION: An auxiliary chamber type gas engine comprises: an auxiliary chamber fuel supply valve that is connected to an auxiliary chamber fuel supply line to control supply of auxiliary chamber fuel to an auxiliary chamber and is opened when an auxiliary chamber fuel line pressure, that is the pressure of the auxiliary chamber fuel supply line, becomes larger than an auxiliary chamber pressure that is the pressure of the auxiliary chamber; an auxiliary chamber fuel line pressure regulation valve that is installed in the auxiliary chamber fuel supply line and can regulate the auxiliary chamber fuel line pressure; exhaust-time auxiliary chamber pressure acquiring means capable of acquiring an exhaust-time auxiliary chamber pressure that is the pressure correlating to the auxiliary chamber pressure at the time of opening of an exhaust valve for controlling a communication state between a cylinder forming a main combustion chamber and an exhaust passage; and a vale opening control device configured to control a valve opening of the auxiliary chamber fuel line pressure regulation valve. The vale opening control device controls the valve opening of the auxiliary chamber fuel line pressure regulation valve according to the exhaust-time auxiliary chamber pressure.SELECTED DRAWING: Figure 1
