Abstract:
Provided is a gas engine configured such that an auxiliary chamber, in which a spark plug is provided at a top part of the auxiliary chamber and an injection hole is provided in a throat formed at a bottom part of the auxiliary chamber, is provided in a main combustion chamber, and during compression, a mixed gas flows from the main combustion chamber into the throat of the auxiliary chamber via the injection hole. A curved surface part is formed along the peripheral edge of an opening end at the throat side of the injection hole, and the throat extends linearly along the central axis of the auxiliary chamber. The ratio of the length of the throat relative to the inner diameter of the throat is from 1.6 to 2.6, and a value obtained by multiplying the ratio of the inner diameter of the throat relative to the radius of the curved surface part by the ratio of the throat diameter relative to the diameter of the top part of the auxiliary chamber is 18 or more.
