Abstract
A precombustion chamber gas engine includes a main-chamber forming portion forming a main combustion chamber, a precombustion-chamber forming portion forming a precombustion chamber including a small-diameter cylinder chamber communicating with the main combustion chamber via a plurality of nozzle holes and a large-diameter cylinder chamber, an ignition device disposed in the large-diameter cylinder chamber of the precombustion chamber, and a precombustion-chamber-gas supply device for supplying a precombustion-chamber fuel gas to the precombustion chamber not via the main combustion chamber. The nozzle hole is formed so that a precombustion-chamber-side straight line passing through a central position of a precombustion-chamber-side opening of the nozzle hole and parallel to an extending direction of a central line of the precombustion-chamber-side opening of the nozzle hole intersects with a main-chamber-side straight line passing through a central position of a main-chamber-side opening of the nozzle hole and parallel to an extending direction of a central line of the main-chamber-side opening of the nozzle hole, and an acute angle between a precombustion chamber central axis of the precombustion chamber and the precombustion-chamber-side straight line is smaller than an acute angle between the precombustion chamber central axis and the main-chamber-side straight line.
