Title: Control device for catalyst temperature-raising system
Inventor: NONOMURA HITOSHI
IPC: F01N3/24
Filed: 2021-06-14
Abstract: To provide a control device for a catalyst temperature-raising system which can raise temperatures of a first catalyst and a second catalyst which are connected to each other in series with a simpler structure, at a lower cost, further efficiently, and in a short time.SOLUTION: A control device for a catalyst temperature-raising system calculates a stoichiometric injection amount, which is an amount of fuel to cylinders 45A to 45D as a theoretical air-fuel ratio with respect to an intake amount of an internal combustion engine 10. The control device calculates an allowable amount at which an NSR 61 (first catalyst) can purify carbon hydride on the basis of a temperature of the NSR 61. When it is determined that warming up of an SCR 62 (second catalyst) is necessary, the control device injects the stoichiometric injection amount in multiple stages so that the carbon hydride remaining in exhaust emission which is exhausted to an exhaust manifold 12A in an exhaust stroke of each of the cylinders 45A to 45D does not exceed the allowable amount of the NSR 61. Part of fuel injected by post-injection is supplied to the NSR 61 together with remaining oxygen as unburnt fuel, and oxidization reaction of the unburnt fuel and the remaining oxygen occurs in the NSR 61, such that temperature of the SCR 62 can be effectively raised by heat of the reaction.SELECTED DRAWING: Figure 1

Abstract: To implement a DBG process without using a tape.SOLUTION: A plate-like workpiece 20 in which lattice-like grooves 29 are formed on its surface 21 is held by suction using a suction surface 110 of a first jig chuck 100 having suction holes 111. Further, in this state, a rear surface 22 of the plate-like workpiece 20 is ground with a grindstone 77 so that the plate-like workpiece 20 is divided into a plurality of chips 27. At this point, the suction holes 111 of the first jig chuck 100 are respectively arranged below the chips 27 in correspondence with the respective chips 27 of the plate-like workpiece 20.

Accordingly, the chips 27 obtained through the division can be prevented from being scattered without attaching a tape on the surface 21 of the plate-like workpiece 20.SELECTED DRAWING: Figure 12
