Abstract: In an air-cooled internal combustion engine with one or more cylinder banks, a cooling-air blower and an intercooler for the air charge, the intercooler--as seen in the flow direction of the cooling-air--is placed directly in front of the cylinder bank, i.e. preferably over its entire length. The intercooler is subject to the full stream of cooling-air passing through the cylinder bank. A comparison of conventional designs and the arrangement described by the invention shows that the power requirements of the blower are reduced by as much as 15% in conventional assemblies, and by even 20% in special-purpose vehicles as described below.

Abstract: A water-cooled internal combustion engine with direct fuel injection and in hich the cylinders are arranged in banks forming the shape of a V, the V-shape space between the cylinder banks is adapted as a receiving chamber for combustion air and for the accommodation of means for fuel injection by individual pumps associated with each cylinder. The provision of a single camshaft is arranged parallel to the cylinder banks and centrally above the receiving chamber and in that the push rods of the inlet and exhaust valves as well as the individual pumps are directly driven by the camshaft.

Abstract: In a water-cooled, multi-cylinder internal combustion engine, which comprises cylinders and a cooling jacket, the cylinders are connected in the lower region thereof to each other and to the cooling jacket, and crankshaft main bearings consisting of two parts which are mutually connected by means of main bearing bolts, the lower ends of the cylinders are connected to the cooling jacket at a height from the bottom edge of the cylinders corresponding to 0.5 to 0.75 times the cylinder diameter, and downwards from this level the lower cylinder ends are connected to each other but otherwise free and unconstrained, and the threads for the main bearing bolts are arranged at a height from the bottom edges being at least that great as the distance of the connection between the cylinders to the bottom edges.

Abstract: A water-cooled internal combustion engine includes piping defining a hydraulic oil circuit having an oil pump and using hydraulic oil lubrication and a cooling-water pump driven as a function of the operating condition of the engine. The hydraulic motor is provided in the circuit for the drive of the cooling-water pump which, by means of a control element, can be switched into the hydraulic oil circuit of the internal combustion engine.

Abstract: An assembly of auxiliary equipment for a water-cooled internal combustion engine having an oil pump, a water pump and an oil cooler/oil filter unit, wherein the oil pump, water pump and oil cooler/oil filter unit are provided as separate interchangeable subassemblies and are combined and interconnected into a constructional unit that can be mounted on the engine.

Abstract: In a water-cooled, multi-cylinder internal combustion engine, which comprises a cylinder block, a cylinder head, and a cooling jacket, all cast in one piece and wherein the cylinder head comprises, for each cylinder of the cylinder block and on one longitudinal side thereof, an intake and exhaust duct as well as valve guide sockets and on the other longitudinal side a mounting socket for an injection nozzle or sparking plug, forming a connection between the end wall of the cylinder and the cooling jacket, at least one fin is provided on the side where the mounting socket is arranged to make an additional connection between the end wall of the cylinder and the cooling jacket.This arrangement compensates for the differential section modulus between the two longitudinal sides of the cylinder head regarded as a bending section, that is to say, the neutral axis of the cylinder head is shifted, at least approximately, back into the plane which contains the cylinder axes.
