The model utility content
Technical problem to be solved in the utility model is the high pressure oil rail that a kind of gasoline in-cylinder direct fuel-injection engine is provided at problems of the prior art, its objective is under the situation that realizes higher jet pressure, make things convenient for the installation and removal of oil inlet pipe, save the spatial arrangement that oil inlet pipe is convenient in the spatial position simultaneously.
The technical solution of the utility model is that the high pressure oil rail of this a kind of gasoline in-cylinder direct fuel-injection engine comprises oily rail body, sensor holder and oil injector seat, one end of described oily rail body is welded with oily rail lid, the other end is welded with the oil-feed base, the other end of oil-feed base is connected with oil inlet pipe, the through-hole structure that the inside of oil-feed base is provided with is communicated with oily rail body, the inside of sensor holder and oil injector seat is equipped with the through hole that communicates with oily rail body inside, and first support, second support are installed in the middle part and the two ends of oily rail body respectively.
Described oil-feed base is a multiaxis shoulder cylindrical outer shape, and inside is the through hole that has conical surface aperture, and the connecting end of described oil inlet pipe is provided with the spherical joint that matches with the conical surface on the through hole, and oil-feed base and oil inlet pipe screw by nut and form sealing.
Described oil-feed base welds together with projection welding and soldering processes by junction plane and oily rail body.
High pressure oil rail with a kind of gasoline in-cylinder direct fuel-injection engine of above-mentioned special construction has the following advantages:
1, the high pressure oil rail of this kind gasoline in-cylinder direct fuel-injection engine is arranged in oily rail end face with the oil-feed base, makes the installation and removal of oil pipe all become convenient, simultaneously the space of oil inlet pipe is moved towards to require to reduce, and saves the space.
2, the oily rail body of the high pressure oil rail of this kind gasoline in-cylinder direct fuel-injection engine is welded into type by the sheet material volume, is suitable for any custom size, and the body bearing pressure is higher; The oil-feed base is arranged on the end face of high pressure oil rail, cancel an oily rail lid of original closed at both ends oil rail, also reduced by an oily rail body simultaneously and be communicated with the port of oil-feed base and the welding process of oily rail lid, also reduce the machining processes of oily rail body oil inlet pipe through hole simultaneously, improved the manufacturing efficiency of oily rail.
3, the high pressure oil rail of this kind gasoline in-cylinder direct fuel-injection engine is rational in infrastructure, practical reliable, it can be good at realizing higher jet pressure, reaches the emission request of better fuel economy, power character and Geng Gao, has advantage simple in structure, easy to process, that cost is lower.
