ENGINE-GENERATOR SYSTEM Russian patent published in 2008 - IPC F02B63/04 H02K7/18 

FIELD: electricity.

SUBSTANCE: invention is attributed to electric engineering. Engine-generator system comprises open frame (F), engine (E) with casing (11) and driven by engine (E) generator (G). Exhaust system muffler (12) in this system is installed at one side of generator (G) and over it. Chamber (41) of muffler unit is formed inside casing (40). The casing (40) comprises several sections. Dividing plate section (42a) forms dividing wall between muffler (12) of exhaust system and generator. Bottom plate section (42b) extends from lower end of dividing plate section (42a) to the side opposite to generator (G). Top plate section (43a) is connected with the top section of dividing plate section (42a) in such a way that it covers exhaust system muffler (12) from the top. End plate section (44a) is connected with the ends of dividing plate section (42a), bottom plate section (42b) and top plate section (43a). These ends are located at side opposite to engine casing (11). Cooling air supply ports (67) at engine side and at generator side (68) are located at the end of muffler unit chamber (41) at the side of engine casing (11).

EFFECT: increase in effectiveness of exhaust gas muffler system resulting in decrease of muffler high temperature influence on the other elements and space occupied by them.
