摘要： A combustion chamber construction includes inlet and exhaust side sloping surfaces. The inlet side sloping surface is formed on one side of a pentroof apex portion as a boundary and which has an inlet port. The exhaust side sloping surface is formed on the other side of the pentroof apex portion as the boundary and which has an exhaust port. A flow improving portion is formed between the inlet port and exhaust port. The flow improving portion includes an inlet flow surface which is formed by recessing part of the inlet side sloping surface and an exhaust side guide surface. One end of the exhaust side guide surface is connected to an exhaust surface of the exhaust side sloping surface and the other end is connected to the inlet flow surface. An angle formed by the inlet flow surface and the exhaust side guide surface is smaller than or equal to an angle formed by the exhaust surface and the exhaust side guide surface.

摘要翻译： 燃烧室结构包括入口和排气侧倾斜表面。 入口侧倾斜面形成在作为边界的顶端顶端的一侧，并且具有入口。 排气侧倾斜面形成在作为边界的顶点顶端的另一侧，并且具有排气口。 在入口和排气口之间形成有流动改善部分。 流动改善部包括通过使入口侧倾斜面的一部分和排气侧引导面凹入而形成的入口流动面。 排气侧引导面的一端与排气侧倾斜面的排气面连接，另一端与入口流动面连接。 由入口流动表面和排气侧引导表面形成的角度小于或等于由排气表面和排气侧引导表面形成的角度。
