Abstract
A low-noise-level combustion engine comprises an engine unit support with auxiliary units rigidly connected thereto, a crankcase and a flywheel case. The engine unit support, as an engine part directly affected by sound vibration, is connected to the crankcase by at least three resonance-absorbing elements which provide power transmission from the engine unit support to the crankcase. The engine comprises further a sealing element located between the engine unit support and the crankcase, which divides the engine into a lower oil-wetted engine region and an upper dry engine region which is oil-tightly sealed against the lower engine region. The sealing element surrounds the engine, the engine unit support, and is attached to the engine unit support and to the crankcase. It has no supporting function and is highly resilient.
