EXHAUST MANIFOLD IN A COOLED AND ISOLATED HOUSING

摘要

The presented Invention relates to the exhaust manifold of internal combustion engines. For higher output of the internal combustion engines, the exhaust gasses are used for propulsion of turbocharger, to compress the engine intake air, in order to increase oxygen content necessary for combustion. Exhaust manifold is made preferably from welded stainless steel structure, consisting of internal exhaust pipe segments, made from at least 2 elements (5) made preferably from heat resistant, low scaling steel, for instance stainless steels EN 1.4435 or EN 1.4841, connected together with longitudinally free movable joints (35), and connected at the manifold inlet side to the engine side gasket plate (1) and on the outlet side to the exhaust gas outlet gasket plate 28, with the mentioned internal exhaust pipe hermetically enclosed in an exhaust manifold skirt (13, 1, 7) filed with pressurised exhaust gas (46), with isolated outside exhaust manifold surfaces (9) and engine liquid coolant (17) cooled outside exhaust manifold surfaces (12, 14, 1, 28).
