摘要： An internal combustion engine 10 is provided with cylinders 19 having a predetermined surface finish thereon comprising of at least two differing patterns. The first pattern is designed to provide a predetermined storage volume for oil used to lubricate a piston 22 which is slidingly engaged in the cylinder 19. The second pattern is different to the first pattern in that it provides little or no storage capacity for the oil. The second pattern is applied to the wall 28 of each cylinder 19 at one or more positions where impingement of unburned fuel against the cylinder wall 28 is to be expected. The reduced storage volume of the second pattern reduces the volume of unburned fuel that can be transferred from the cylinder 19 to the oil supply of the engine 10.
摘要翻译： 内燃机10设置有具有预定表面光洁度的气缸19，其上包括至少两种不同的图案。 第一图案被设计成为用于润滑滑动地接合在气缸19中的活塞22的油提供预定的存储量。第二图案与第一图案不同之处在于它为油提供很少的或不存在的储存能力。 第二模式在一个或多个位置上被施加到每个气缸19的壁28上，其中预期未燃烧的燃料撞击气缸壁28。 第二图案的减小的存储容积减小了可从气缸19传递到发动机10的供油的未燃燃料的体积。
