FIELD: engines and pumps. ^ SUBSTANCE: exhaust device comprises cylinder head block 10 with exhaust channels 12. Each first end 14 of every channel is communicated with combustion chamber 16 while second ends enters air collector chamber 20 of exhaust manifold 22 integrated into cylinder head block. In compliance with this invention, said air collector chamber 20 is arranged in element 26 arranged inside cylinder head 10. Note here that said plug-in element 26 is thermally isolated from cylinder block 10 by thermal isolation means 28. Plug-in element 26 is made up of tubular insert 26 with orifices 34 and outlet channel 24 fitted in cylinder head block inlet 32. Orifice 24 communicated with exhaust channel second ends 18 while inlet channel 24 extends beyond cylinder head 10. The inlet channel (24) is communicated with the exhaust gases cleaning device. ^ EFFECT: efficient off-gas cleaning, thermal isolation of manifold from cylinder head block. ^ 7 cl, 1 dwg |
