摘要:
A direct injection injector for an engine includes a body forming the outer structure and having a space therein, a needle inserted to slide linearly in the body and having a hole therein forming a fuel channel, and a cylinder nozzle fitted on needle to communicate with hole and having a nozzle hole for injecting fuel, such that it is possible to prevent caulking in which the nozzle of the injector is clogged with soot while injecting fuel at relatively low pressure, change the spray type of the injected engine in various shapes, and sufficiently decrease the size of droplet of the fuel.

A refrigerator is provided. The refrigerator may include a refrigerator body having at least one storage compartment and an opening, and a main door for opening and closing the storage compartment, the main door also having an opening corresponding to a receiving compartment formed therein. A sub door may be provided to open and close the opening of the main door, and a gasket may be provided along an edge of a rear surface of the sub door to contact a front surface of the main door and seal an interior of the main door when the sub door is closed. A heat transfer member may extend from the inside of a side to the inside of a front surface of the main door.

An idler device may include first bearings rotatably supporting an idler to an idler shaft, wherein a portion of the idler may be rotatably mounted to the idler shaft, and second bearings rotatably supporting the idler shaft.
摘要:
A shelf and a refrigerator having such a shelf are provided. The shelf may include a support frame fixed to an inner surface of a storage compartment of the refrigerator, the support frame including body having a plurality of coupling holes formed along a longitudinal direction, spaced apart at predetermined intervals, and a cover coupled to the body to selectively open and close the plurality of the coupling holes. The cover may include a fixing portion for fixing the cover to the support frame body, and a plurality of opening/closing portions extending from the fixing portion, corresponding to the plurality of the coupling holes, to independently open and close the plurality of the coupling holes. One or more of the plurality of the opening/closing portions may be moved by the shelf plate to couple the shelf plate to the support frame.

摘要:
Provided is a combustion generating device of an internal combustion engine, which is capable of performing very precise flame control through a simple structure which does not need a prechamber and reducing harmful exhaust gas through low-temperature rapid combustion. The combustion generating device includes: an ignition system generating a spark; and an injector generating a mixture by mixing air and fuel and injecting a flame into a combustion chamber, the flame being generated by applying the spark to the mixture.
