INTERNAL COMBUSTION ENGINE MUFFLER-GENERATOR Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates mainly to exhaust mufflers of internal combustion engines. Proposed muffler-generator makes it possible to get additional dc source designed for supply of electrical devices by increasing degree of utilization of internal energy of exhaust gas flow of internal combustion engine. Muffler contains noise-absorbing element made of heterogeneous thermoelectric materials with hole and electron conduction connected into common electric circuit which generate direct current under action of exhaust gas heat. EFFECT: increased degree of utilization of exhaust gas energy, provision of additional power source. 2 dwg
