It is an air-cooled 4-stroke boxer engine with four cylinders. The bore is 111.1 mm and the stroke is 98.4 mm. This results in a displacement of 3816 cm³ (235 cubic inches). The propeller is driven directly. The compression is 6.75: 1 to 9.7: 1, depending on the variant. The engine was approved on August 26, 1940 and is still in production today.
The O 235 provides between 75 kW (100 hp) at 2450 min -1 and 93 kW (125 hp) at 2800 min -1 . Tens of thousands of examples of this engine have been built to date. It is one of the most widely used aerospace engines. Among other things, he came to the Beechcraft 77 , the Cessna 152 , Robin R3000 , Piper J-5 , Piper PA-12 and Piper PA-38 are used.
