The Continental O-190 is a series of American four-cylinder, air-cooled aircraft engines that were developed by Continental Motors in the 1940s. They were derived from the earlier O-170 engine by increasing the bore and stroke. The O-190 engines produced either 75 hp (56 kW) or 85 hp (63 kW), depending on the model and the maximum rpm. The engines were used in many light aircraft designs, such as the Auster Arrow, the ERCO Ercoupe, the Thorp T-11, and the Funk B. The engines had a simple and reliable design, with one intake and one exhaust valve per cylinder, two magnetos for ignition, and a carburettor or fuel injection system for fuel delivery. These engines are typically used for lightweight utility or DIY aircraft.
