Abstract: A method of pilot injection control which avoids a change in the number of pilot injections in a transient response of an engine to improve driving and handling feeling. When pilot injection is performed, it is determined whether fuel injection amount Q immediately before the pilot injection is more than a maximum value Qmax and, if so, number of pilot injections is fixed to a predetermined value. When fuel injection amount Q is determined to be not more than the maximum value Qmax, it is determined whether fuel injection amount Q is lower than a minimum value Qmin, and, if so, the number-fixed control of the pilot injections is released and map control is started where the pilot injection number is determined based on a map.

Abstract: Change in number of pilot injection is avoided in a transient response of an engine, so that driving feeling and travelling feeling are improved. When pilot injection is performed, whether fuel injection amount Q immediately before the pilot injection is more than a maximum value Qmax is determined (S100), and in the case that the fuel injection amount is determined to be more than the maximum value Qmax, number of pilot injection is fixed to a predetermined value (S102), and on the other hand, in the case that the fuel injection amount Q is determined to be not more than the maximum value Qmax, whether the fuel injection amount Q is lower than a minimum value Qmin is determined (S104), and when the fuel injection amount Q is determined to be lower than the minimum value Qmin, number-fixed control of pilot injection is released, and map control where pilot injection number is determined based on a map is started (S106).

Abstract: A scrap collection system for collecting scraps produced when materials such as metals and plastics are processed by a processing machine such as a pressing machine and a lathe. A scrap receiver receives scraps from the processing machine and has at least one hopper positioned beneath the processing machine. A scrap collector box vertically below the hopper has at least one opening into which a conduit is directed for delivering scraps into the scrap collector box, and at least one opening having a filter for discharging air from the scrap collector box.
