    • A torch ignition type internal combustion engine which has no intake valve in the auxiliary combustion chamber and which can effectively purge exhaust gases from the auxiliary combustion chamber to eliminate ignition failures, the engine comprising a cylinder; a cylinder head having a semi-spherical inner wall; a reciprocating piston snugly received in the cylinder; a main combustion chamber defined between the cylinder head and piston and having intake and exhaust valves to control intake and exhaust ports in the cylinder head; an auxiliary combustion chamber provided at a suitable position in the cylinder head; and a passage intercommunicating the main and auxiliary combustion chambers. The passage opens into the main combustion chamber at a position close to one of the intake valve and the exhaust valve. In one embodiment, the passage opens into the main combustion chamber at a position close to and substantially intermediate the intake and exhaust valves. In another embodiment, the passage opens into the main combustion chamber near the intake valve and close to one side of the semi-spherical inner wall of the cylinder head.
    • 一种火炬点火型内燃机,其在辅助燃烧室中不具有进气阀,并且能够有效地净化来自辅助燃烧室的废气以消除点火失效,该发动机包括气缸; 具有半球形内壁的气缸盖; 往复式活塞紧贴在缸体中; 主燃烧室限定在气缸盖和活塞之间并具有进气和排气阀,以控制气缸盖中的进气和排气口; 辅助燃烧室,设置在气缸盖中的适当位置; 以及将主燃烧室和辅助燃烧室相互连通的通道。 通道在靠近进气阀和排气阀之一的位置处通入主燃烧室。 在一个实施例中,通道在接近和基本上进入和排出阀的中间的位置处通入主燃烧室。 在另一个实施例中,通道通向进气门附近的主燃烧室并且靠近气缸盖的半球形内壁的一侧。
