An engine block includes a cylinder head, a plurality of bearing caps for a crankshaft, a cylinder block disposed between the cylinder head and the bearing caps, a plurality of fastening members for fastening the cylinder head and the bearing caps to each other, and a plurality of columnar members interposed between the cylinder head and the bearing caps to receive the fastening forces of the fastening members. Thus, it is possible to provide an engine block including a cylinder block reduced in weight by a remarkable reduction in required strength.

Engine block

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.
