Fig. 1 illustrates the schematic diagram according to the first combustion power machine system 10 of the present invention with two combustion power machines 11,12.The combustion power machine 11 and 12 illustrated in fig. 1 and 2 is combustion engines, is preferably marine diesel oil combustion engine.Here it should be pointed out that the present invention is not limited to adopt the combustion combustion power machine system of explosive motor.The present invention also can be used for such combustion power machine system, and namely the combustion power machine of this combustion power machine system is designed to fluid flowing machine, such as combustion gas turbine etc.
In the combustion power machine 11,12 of combustion power machine system 10, fuel can be burned to form exhaust, and wherein the exhaust of combustion power machine 11,12 can guide via the exhaust after treatment system 13 shared of the exhaust aftertreatment for being vented.
In the exemplary embodiment shown in fig. 1, combustion power machine 11 is assigned with shutoff device 14, this shutoff device is positioned at the downstream of combustion power machine 11 to be thrown off from exhaust stream by combustion power machine 11, in particularly combustion power machine 12 runs combustion power machine 11 cuts out, thus prevent the exhaust of the combustion power machine 12 of operation along the backflow in the direction of static combustion power machine 11.This shutoff device 14 is generally Closure panel plate (flap) etc.In addition, Fig. 1 illustrates control gear 15, via described control gear, according to the dotted arrow of Fig. 1, the operation of combustion power machine 11,12 can be controlled and/or regulate, and via described control gear, described shutoff device 14 also can be closed and open, be namely static with combustion power machine 11 or run relevant.Therefore, when particularly combustion power machine 11 is static, combustion power machine 12 runs, the shutoff device 14 being assigned to combustion power machine 11 automatically closes via control gear 15.
According to Fig. 1, sensor 16 is arranged in the downstream of combustion power machine 11, combustion power machine 11 can be closed and combustion power machine 12 runs in the exemplary embodiment shown in fig. 1, and be dispensed to can the upstream of shutoff device 14 of pent described combustion power machine 11, by means of sensor 16, gas componant and/or the gas temperature of the upstream of the downstream of static combustion power machine 11 and the shutoff device 14 of closedown can be determined.
Accordingly, check to run at combustion power machine 12, the static and shutoff device 14 of combustion power machine 11 is when cutting out, whether the direction along static combustion power machine 11 exists exhaust gas recirculation (although shutoff device 14 is cut out).Described inspection is automatically performed by control gear 15.
