凸輪傳動機構的活塞式引擎為何沒能廣泛應用？

加工成本應該不會低，組裝維修要難些。占用空間大。

論壇有高手，看過之后很受啟發。

另外這個是高副配合，比曲軸瓦壽命上差多了。

設計整車時不好放置，裝配時還要轉來轉去

很有創意的結構，不過就如圖一的，如果活塞上的凸輪磨損后會不會出現問題。如果是用于壓縮機的話不知道效果如何啊。

Left: The Fairchild-Caminez Cam Engine: 1926.

The Fairchild-Caminez 447 engine was a four-cylinder air-cooled radialintended for aircraft useage. It was designed by Harold Caminez, who had previouslyworked in the Engine Design Section of the US Army Air Service. The pistonsacted on a leminiscate-shape cam, which made only one revolution for every twopiston cycles, so for the same number of power impulses the engine ran at halfspeed. The pistons were connected by steel links to keep them pressed againstthe cam; the cylinder were steel with aluminium heads.
The Fairchild-Caminez 447 was first flown in an Avro 504 from Farmdale, LongIsland, New York, in 1926. It was successfully endurance-tested in 1927, andwas the first ever axial engine to receive a US Dept of commerce typecertificate.

謝謝！ 二戰時飛機的發動機多是星型的{:soso_e100:}

機加跟裝配的話，有點難度
