Abstract
The present invention provides for an internal combuston engine having housing parts such as a cylinder, cylinder head and crankcase formed of a light metal. A plurality of tightening screws are provided for securing the above-mentioned parts so as to form an engine block, the screws having threaded ends which are received in the heads of steel tie rods which are integral with the crankcase and which extend substantially parallel to the cylinder axis. When the engine is in use, the tightening of the light metal housing parts by way of the steel tie rods, prevents undesired deformation of the crankcase.
