摘要:
A drying method for use of latent heat includes the following steps: A. installing a heating plate and a latent heat device having wax in a dry environmental space; B. placing an article to be dried in the dry environmental space; C. absorbing outside heat energy with the heating plate for drying process; D. utilizing the latent heat device to accumulate heat energy; and E. releasing the heat energy from the latent heat device for drying process. A drying apparatus for use of latent heat includes a box, a heating plate provided on the box, and a latent heat device provided in the box. The box has an entrance and a vent. The entrance is provided with a door to seal the entrance. The latent heat device comprises wax therein to do heat exchange through for drying purpose.
摘要:
An air-assisted fuel injection applied in the two-stroke engine of flame-jet ignition type which a fuel pump and fuel pressure regulator valve establish stable fuel rail pressure. With respect to each cylinder, a pair of fuel injection electromagnetic valve inject fuel under this pressure. The injected fuel is not directly injected into the cylinder, but is blown into main combustion chamber in the cylinder and prechamber cavity in a torch-forming plug by high speed flowing air. The ignition is performed in such a manner that the pre-mixed fuel air mixture in the prechamber cavity is first ignited by a spark discharge to form specifically shaped flame jet which is injected from one or more orifices located on lower portion of the torch-forming plug so as to successively ignite the pre-mixed fuel air mixture in the main combustion chamber. The high speed flowing air is supplied in such a manner that a small air pump and an air pressure regulating valve provide constant pressure air and with respect to each cylinder, a pair of main air injection electromagnetic valve and subsidiary air injection electromagnetic valve properly inject high speed flowing air to assist in atomizing and transferring the fuel injected from the fuel injection electromagnetic valves.
