Title:
副室式ガスエンジン
Document Type and Number:
Japanese Patent JP6899224
Kind Code:
B2
Abstract:
A precombustion chamber gas engine including a precombustion chamber communicating with a main combustion chamber includes: a precombustion-chamber-fuel supply line through which a precombustion chamber fuel flows; a precombustion-chamber-fuel supply valve connected to the precombustion-chamber-fuel supply line and controlling supply of the precombustion chamber fuel to the precombustion chamber, the precombustion-chamber-fuel supply valve being configured to open when a precombustion chamber fuel line pressure, which is a pressure of the precombustion-chamber-fuel supply line, is larger than a precombustion chamber pressure, which is a pressure of the precombustion chamber; a precombustion-chamber-fuel-line-pressure adjustment valve disposed on the precombustion-chamber-fuel supply line and capable of adjusting the precombustion chamber fuel line pressure; an exhaust-precombustion-chamber-pressure acquisition unit capable of obtaining an exhaust precombustion chamber pressure which is a pressure related to the precombustion chamber pressure when an exhaust valve controlling a communication state between an exhaust passage and a cylinder forming the main combustion chamber is open; and a valve-opening-degree control device configured to control an opening degree of the precombustion-chamber-fuel-line-pressure adjustment valve. The valve-opening-degree control device is configured to control the opening degree of the precombustion-chamber-fuel-line-pressure adjustment valve in accordance with the exhaust precombustion chamber pressure obtained by the exhaust-precombustion-chamber-pressure acquisition unit.
