ABSTRACT:
An internal combustion engine has opposed cylinders defining a central combustion chamber therebetween. A pair of crankshafts are positioned outwardly of the respective cylinders by a distance which allows the pistons and connecting rods to be withdrawn from the bottoms of the cylinders, when disconnected from the crankshafts, without interference from the crankshafts. The cylinders are inclined to the horizontal and define a substantially V-shaped combustion chamber. The engine is particularly suited for use in vehicles and is provided with a mounting arrangement which promotes pivoting of the engine in the event of a collision rather than projection of the engine through a firewall of the vehicle.
