WASTE HEAT RECOVERY DEVICE OF MULTI-CYLINDER INTERNAL COMBUSTION ENGINE

摘要

A waste heat recovering device for a multi-cylinder internal combustion engine, wherein among a plurality of exhaust pipes extending from cylinders of a multi-cylinder internal combustion engine, a plurality of exhaust pipes unlikely to cause exhaust interference are collected to form one or more collecting pipes. A heat exchanger for recovering heat of exhaust gas is provided in the one or more collecting pipes. Therefore, a waste heat recovering device can be provided, in which the number of heat exchangers is reduced compared to the number of cylinders of the multi-cylinder internal combustion engine to reduce rest periods of the heat exchanger and reduce spaces occupied by the heat exchanger.
