Methods and systems are provided for operating an engine having a plurality of notch settings. One example method comprises, during a first notch setting, adjusting engine injection timing in a first proportion to an increasing temperature, and during a second notch setting higher than the first notch setting, adjusting engine injection timing in a second proportion to the increasing temperature, the second proportion lower than the first proportion.

The invention relates to a process and a device for organic solvent recovery and air cycle use in dry spinning. A spinning shaft is sequentially provided with a high-temperature gas inlet, an organic solvent-containing gas exhaust port, a secondary high-temperature gas inlet and a cooling air exhaust port from top to bottom; a spinning shaft gas treatment system comprises a gas treatment loop I and a gas treatment loop II, the gas treatment loop I is used for recycling most of solvent from gas exhausted from the exhaust port, and the gas treatment loop II is used for further separating and recycling the organic solvent; a turning wheel is cooled and the regeneration treatment is realized due to the design of the pipeline and the own energy, the regenerated gas can be continuously used for the gas treatment system, and no gas is exhausted outside the system. The moisture content of circulating air and the recycled organic solvent is low, no organic solvent hydrolysis phenomenon occurs in the follow-up treatment, no low-temperature chilled water is required during solvent recovery, and zero emission in chemical fiber production is realized.

The invention relates to the manufacturing field of hard brittle materials, in particular to a diamond brazing tool which is in the combining structure of joint and staircase-like steps. The invention comprises a bit, a saw blade and a grinding wheel, and is mainly used for the drilling, cutting, grinding and polishing of stone materials, concrete, glass, ceramics, crystal, hard alloy and the like materials. The matrix structure of the working area of the diamond brazing bit, the saw blade and the grinding wheel is designed to a combining structure of joint and staircase-like steps, diamond abrasive is brazed on the step surface and in the joint, and the diamond abrasive is put into use step by step when in the process of drilling, cutting, grinding and polishing, thereby the contact surface with the processing object is reduced, the grinding force is small and the cutting efficiency is high.

The technical problem petroleum resource shortage due to the fact that fuel engines are mainly dependent on petroleum fuel, and atmospheric pollution due to combustion of petroleum resources in the prior art can be solved.

A method for producing a low-carbon hot-rolled thin steel plate with a multi-layered structure belongs to the technical field of metallurgy. The production process of the method is as follows: continuous casting into billets → soaking in the 1# heating furnace → rough rolling in the rough rolling group → heating in the 2# heating furnace → high-pressure water dephosphorization → finishing rolling in the finishing rolling group → cooling by the layer cooling device → coiling machine coil Pick. The low-carbon hot-rolled thin steel sheet with multi-layered structure obtained by this method is different from the composite steel plate obtained by the composite process such as explosion or hot rolling, and also different from the homogeneous steel plate obtained by the ordinary hot rolling process or cold rolling process. The low-carbon hot-rolled thin steel sheet produced by this method has very high edge ductility, low risk of edge cracking, and excellent performance, which can well meet the needs of downstream users. The method omits the cladding process of the clad steel plate, avoids the complex preparation process of the gradient material and the cracking of the homogeneous steel plate, and has the advantages of simplifying the process, reducing carbon emissions, high production efficiency, green environmental protection and low cost.
