摘要： An internal combustion engine comprises a cylinder and an intake passageway opening into the cylinder. In order to secure sufficiently high volumetric efficiency at high speed under high load operating conditions, the intake passageway is so configured as to pass therethrough a sufficient volume required for the combustible charge to be drawn into the cylinder per unit time. The intake passageway is provided with swirl means for causing the combustible charge passing through the intake passageway to swirl in the cylinder. The swirl means comprises at least one flow restrictor means so arranged as to urge the combustible charge to enter into the cylinder in a tangent direction to the cylinder wall. Control means is provided whereby the flow restrictor means reduces effective flow area thereof at low speed under light load operating conditions, thus securing strong swirl, and the flow restrictor means increase effective flow area thereof at high speed under high load operating conditions, thus securing high volumetric efficiency.
摘要翻译：内燃机包括气缸和通向气缸的入口通道。为了在高负载运行条件下高速地确保足够高的体积效率，进气通道被配置成通过其中每单位时间内可吸入的汽油被吸入汽缸所需的足够的体积。进气通道设置有涡流装置，用于使通过进气通道的可燃气体在气缸中旋转。涡流装置包括至少一个限流装置，其被设置成促使可燃气体沿与气缸壁相切的方向进入气缸。提供控制装置，由此在轻负载运行条件下，限流装置在低速下减少其有效流动面积，从而确保强烈的漩涡，并且限流装置在高负载运行条件下在高速下增加其有效流动面积，从而确保高体积效率。

摘要： An internal combustion engine comprises a main combustion chamber defined on one side by a piston and also having an auxiliary combustion chamber connected by a torch flame passageway to the main combustion chamber. The ratio of cross sectional area cut through the torch flame passageway at right angles thereto to the volume of the auxiliary combustion chamber being from a value that is greater than 0.2cm.sup.2 /cc to 0.3cm.sup.2 /cc. The volume of the auxiliary combustion chamber is from 6 percent to 15 percent of the total clearance volume that is the combined volume including a volume of the auxiliary combustion chamber, a volume of the main combustion chamber at the top dead center position of the piston and a volume of the torch flame passageway.
