The tube tracking oil sprayer includes one rotation shaft, one material feeding pan with notch in the edge for fixing tube, one spray gun frame beside the material feeding pan, one synchronous driving mechanism, and one spray gun frame detaching and resetting mechanism. The tube tracking oil sprayer has the features of high compatibility, sufficient oil spraying time, no contamination on the injector, high safety and high reliability.

The invention belongs to the technical field of fuel injection systems of gasoline engines, and relates to a GDI fuel injector utilizing PTC thermal sensitive ceramic for heating. An insulation sheath, a PTC thermal sensitive ceramic pipe and a heat conduction round pipe in the GDI fuel injector sequentially wrap the outer ring of the lower portion of a needle valve, and insulation gaskets are arranged between the upper end of the PTC thermal sensitive ceramic pipe and a boss of the needle valve of the fuel injector and between the lower end of the PTC thermal sensitive ceramic pipe and the boss of the needle valve of the fuel injector respectively. The upper end of a positive wire and the upper end of a negative wire are connected with a wiring harness plug through electric conduction carbon rings and an electric conduction spring, the lower end of the positive wire and the lower end of the negative wire are connected with the positive pole and the negative pole of a heating electrode respectively, and the electric conduction carbon ring I and the electric conduction carbon ring II are connected through the electric conduction spring. The GDI fuel injector belongs to internal heating, fuel in the fuel injector can be heated to high temperature within short time, the fuel injection effect is good, the spraying effect in an air cylinder of a gasoline direct injection engine is greatly improved, cold start combustion efficiency is improved, and cold start tail gas emission is reduced. The GDI fuel injector is simple in structure, and other systems of an internal combustion engine do not need to be greatly modified.

The invention discloses a polyester staple fibre water-oil wet spraying machine comprising an oil spray tank, a movable oil tank, a filter screen, an oil return tank, an oil tank, an oil return hole, an oil inlet, an oil outlet, an oil outlet pipe, a multistage gear pump, a drive motor, a connecting pipe, an oil spray pipe, a plurality of oil spray holes and a compressed air pipe, wherein the movable oil tank is movably arranged at the lower end of the oil spray tank; the filter screen is arranged in the middle of the movable oil tank and can divide the movable oil tank into the oil return tank and the oil tank; the upper end of the oil return tank is provided with the oil return hole mutually communicated to the bottom of the oil spray tank; the oil tank is respectively provided with theoil inlet and the oil outlet; the oil outlet is connected with the multistage gear pump through the oil outlet pipe; the multistage gear pump is connected with the drive motor and connected with the oil spray pipe arranged in the oil spray tank through the connecting pipe; and the oil spray pipe is uniformly provided with the plurality of oil spray holes and is connected with the compressed air pipe. The oil spray holes are difficult to block and connected with the compressed air pipe so that the oil spray amount can be regulated according to the magnitude of working speed; and the invention has the advantages of uniform oil spray, good oil spray effect, oil consumption saving and reduced using cost.

The invention relates to the technical field of automobile control, in particular to a fuel injection control method for a vehicle equipped with a direct injection engine. The fuel injection activation conditions include the activation conditions based on fuel rail fuel pressure and the activation conditions based on the number of engine operating cycles. Fuel injection is allowed only when the two activation conditions are met at the same time; the activation conditions based on fuel rail fuel pressure refer to the current fuel rail pressure value Greater than the minimum fuel rail fuel pressure determined based on the current engine water temperature and the ambient atmospheric pressure of the engine; the activation condition based on the number of engine operating cycles means that the actual number of engine operating cycles is greater than the minimum number of engine operating cycles determined based on the current engine water temperature. The present invention fully considers the control method of various factors affecting the fuel atomization effect, takes into account the influence of water temperature, atmospheric pressure and engine operation cycle times on the fuel atomization effect, and selects the most reasonable fuel injection control scheme to achieve Optimum spray effect.

The invention is concerned with Silicone oil spreading equipment of injector assembly machine, belonging to machine technology. It solves the pollution on outside of canister and bad spraying effect of the existing Silicone oil spreading equipment. This equipment relates to a turning axis fixed with a turntable running with the turning axis. There are some blocks on the rim of turntable for fixing canister, and there is rack of spray oil on the side of turntable which having spray oil framework relating to head to spray oil, oil cup connecting with the head and spraying framework set on the head. There is driving framework between the head of spray oil and rack of spray oil to drive the spray framework on the top of block. This spray effect is good and the spray time is enough of this equipment and it can spray to the canister well and truly.
