Embodiment Construction
[0022] see figure 1 and 2 Open the spark plug installation hole 2 on the cylinder block 1, and install the spark plug on the bottom of the ignition groove. Since the ignition groove is designed to be suitable for generating a stable air swirl, the shape of the groove 4 must be well coupled with the direction of the airflow in the cylinder. 6 , so that the air flow enters the channel smoothly, that is, connect the front wall of the ignition tank with the cylinder profile with a small arc, and connect the rear wall with the cylinder profile with a large arc. The specific processing method is to cast with the cylinder body. When casting Rectangular pits are left on the front and rear walls to inlay silicon carbide sheets 3; in order to prevent air leakage during engine operation, the groove width is designed to be 3 mm. Propagating quenching phenomenon, inlaid silicon carbide sheet with platinum catalyst coating 5 on the wall surface of the ignition tank, under the catalytic act...
