IC piston engine with noise insulation - has cylinder block and crankcase completely enclosed by sound damping outer structure

摘要

The i.c. engine has noise insulation covers over most or all of its surfaces. The surface formed by the cylinder block (1) and crankcase (2) which is inclosed and oil-tight, is completely enclosed by a sound insulating outer structure (11). The structure pref. consists of plates mounted at the ends and sides on flanges at the top and bottom of the block, where little vibration is generated, partic. at the corners. ADVANTAGE - Low-cost design and maintenance.
