Abstract
An engine body supports a cylinder having a piston reciprocally mounted therein. An auxiliary inlet valve is provided for introducing compressed air into the cylinder above the piston. A connecting rod is pivotally connected between the piston and a lever which is pivotally supported by the engine body. The lever rotatably supports a drive roller which is disposed in contact with a cam surface on a member drivingly connected to an output shaft. The lever is formed of strong elastic material and an operating device selectively locks the lever in a first position where the drive roller is out of contact with the cam surface and in a second position where the lever is deformed so as to act as a bar spring to urge the roller into continuous contact with the cam surface as the output shaft and member connected thereto rotate. A plurality of cylinders and associated components are disclosed including a six cylinder engine arranged in three rows of two cylinders each and two columns of three cylinders each.
