Title:
ENGINE DEVICE
Document Type and Number:
Japanese Patent JP2015086725
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an engine device capable of assembling exhaust pipes 51, 52, and 66 and an air supply pipe 73 with high stiffness by using an upper surface angle corner portion of a cylinder block 44 of an engine 25, and simplifying a supporting structure of the exhaust pipes 51, 52, and 66 and the air supply pipe 73.SOLUTION: In an engine device disposing a first supercharger 56 and a second supercharger 58 in series in an exhaust gas discharge path of an engine 25, the first supercharger 56 and the second supercharger 58 are distributively disposed on the opposite side surface to the engine 25. An upstream side exhaust pipes 51 and 52 between the engine 25 and the first supercharger 56, a downstream side exhaust pipe 66 between the first supercharger 56 and the second supercharger 58, and an air supply pipe 73 between the first supercharger 56 and the second supercharger 58 are extended so as to be generally flush with the arrangement height of a head cover 47 on an upper surface of the engine 25.
