    摘要: In an internal combustion engine the power generating parts mainly responsible for body resonance and sound vibration such as the crankshaft (3), cylinder block and cylinder head (35) are combined in a power unit which is supported in the crankcase (4) on elastic vibration-absorbing mountings (2) with the sidewalls of the crankcase (4) extending above the crankshaft axis (3).By this arrangement the crankcase (4) is free from direct vibrations leaving other non-power transmitting engine parts mounted above the crankcase (4) which require means to suppress radiated noise.In one embodiment the induction manifold (7) and mounting parts (13, 14) thereof together with the rocker cover (20) are insulated from the cylinder head (35) by vibration-absorbing elements (8,15,16,21,26) and are so shaped and arranged that they provide a screen for noise radiated from the cylinder head (35). Thus, essential parts of the engine have the secondary function of reducing the level of noise emitted by the engine.

    摘要: An internal combustion engine comprises an engine unit support and a crankcase which parts are connected by a resonance-absorbing element. The engine parts located above the resonance-absorbing element are encased by a noise-suppressing encapsulation. The exhaust pipe and the inlet pipe penetrate the encapsulation without touching it and are connected to the cylinderhead by vibration-insulating couplings. Supporting arms are provided which support the exhaust and the inlet pipes. The supporting arms are secured to the crankcase which is freed from body resonance due to the resonance-absorbing element. The supporting arms take over all holding and vibration forces so that the vibration-insulating couplings may be designed very soft in the sense of optimal vibration insulation.
