Abstract
PURPOSE:To prevent blast-away of burning gas and oil rise by forming a piston wall in a specific design. CONSTITUTION:The profile of the wall of a piston 1 gains in diameter from a piston top land B to a skirt C gradually. The second ring land a2 and third ring land a3 are equal to or approximately larger in external diameter than the skirt C. The diameter of the area near the skirt C of the larger diameter ring land A is smaller than or equal to the diameter of the area near the top land B. As coming near to the area near the skirt, the ring land A increases in external diameter so that an oil sump 15 is formed between the piston wall near the skirt and a cylinder liner 2. Reduced swing of the piston 1 may prevent blast-out of burning gas and oil rise.
