CONSTITUTION:A drawing device 12 draws a palette 11 from a feed-in device to place the same on an internal combustion engine support stand 7 and an internal combustion engine 3 is supported on the support stand 7 through the palette 11. A testing device 4 performs various tests of the engine 3. At this time, positioning pins are inserted in the positioning holes of the palette 11 not only to accurately fix the engine 3 to the support stand 7 but also to bring the connection flange of the engine 3 into contact with the flange part of a connector 19 under pressure to connect the engine 3 to a piping group 18. Fuel, air and cooling water are supplied to the engine 3 from the respective pipings 18a, 18b, 18c of a fuel system, an air system and a cooling water system during testing and the exhaust gas and waste cooling water from the engine 3 are discharged. In this case, the piping group 18 is received in a base stand 1 and the lateral periphery of the testing device 3 can be utilized as a working space and it can be prevented that the piping group 18 obstructs a worker.

Is composed of an internal combustion engine support base 7 and a control unit 8 standing from the rear end side of the internal combustion engine support base 7. The internal combustion engine support base 7 is composed of a free roller conveyor 10 and a retracting device 12 for retracting the pallet 11 onto the free roller conveyor 10.

The control unit 8 is formed in a rectangular parallelepiped shape having substantially the same width as that of the internal combustion engine support base 7, and instruments and operation panels are provided on the front and side faces thereof.
The internal combustion engine 3 is supported on the pallet 11 via support legs 13. A pit 14 is formed below the internal combustion engine support base 7. Reference numeral 15 denotes an openable / closable cover that covers the internal combustion engine support base 7, and the opened cover 15 is housed in the pit 14.

A connection device 19 (junction) for connecting the pipe group 18 to the internal combustion engine 3 side is provided at the rear portion of the internal combustion engine support base 7. The pipe group 18 of each internal combustion engine support base 7 is arranged on one side of the internal combustion engine support base 7 (that is, between the adjacent internal combustion engine support bases 7) and housed in the turntable 1. There is. The pipe group 18 is divided into a fuel system pipe 18a, an air system pipe 18b, and a cooling water system pipe 18c, and they are arranged in a panel box 20 which is embedded in the turntable 1 and has an open upper surface. The top of each panel box 20 is a cover 21
Respectively covered by.

As shown in FIG. 4, the connection device 19 includes:
Oil supply pipes connected from the system pipes 18a, 18b, 18c
23, a cooling water supply pipe 24, a cooling water drain pipe 25, an exhaust pipe 26, etc. are connected, and each of these pipes 23 to 26 communicates with a plurality of flange portions 19 a formed in the connection device 19.

At the end of each pipe 30 on the internal combustion engine 3 side, a connection flange 27 is provided which is supported by the pallet 11 side so that it can be pressed into contact with and separated from the flange portion 19a of the connection device 19. A positioning pin 28 is provided at both ends of the connecting device 19, and a positioning hole 29 is formed at the tip of the pallet 11 so that the positioning pin 28 can be inserted and removed.
