Internal combustion engine with a charger in accordance with the principle of positive displacement

摘要

In a reciprocating internal combustion engine with a mechanically-driven charger (20), the number and disposition of cylinders of the internal combustion engine is such that free forces/moments of inertia are still provided. At least one shaft of the mechanical charger is disposed parallel to the crankshaft of the reciprocating internal combustion engine. The mechanical charger (20) is driven in an angle-synchronous manner with the crankshaft (32) of the reciprocating internal combustion engine. The transmission ratio between the charger and the crankshaft is in whole numbers. The charger (20) has a balancing centrifugal weight on at least one of its shafts which during operation counteracts the free forces of inertia of the reciprocating internal combustion engine for the purpose of a low-vibration or vibration-free operation of the internal combustion engine.
