ABSTRACT:
A propulsion arrangement which includes two diesel engines with one of the two engines having a first compression ratio for ensuring a reliable starting and the second engine having a compression ratio that permits high supercharging and high average pressure. Each of the engines include an exhaust supercharger with surplus exhaust from the exhaust driven supercharger of the first engine being supplied to the second engine to prepare an air charge of the second engine for reliable ignition conditions in a partial load operation of the second engine. A device may be provided for heating up the air charge of the second engine at least in one of an idling and partial load operation with a temperature regulator controlling the temperature of the air charge of the second engine so as to set the temperature for the air charge such that at each rpm a final compression temperature exists in the cylinders of the second engine which is necessary for ignition in that engine. A common cooling circuit is provided for the second engine, which circuit includes a common main heat exchanger having a coolant pump driven by the first engine. An air charge cooler is associated with both the first and second engine and a supplementary heat exchanger may be provided for cooling the coolant in the circuit of the engine prior to entering the air charge cooler associated with the second engine. The engines may be arranged one behind the other with at least one of a rigid or elastic connection between the respective crank shafts of the engine, or the engines may be disposed laterally adjacent one another with a coupling being provided between the engines so as to result in a collective drive.
