Crossing spray orifice type injection nozzle of internal combustion engine

The invention relates to a cross orifice typed injection nozzle for an internal-combustion engine and belongs to an oil injection device of a fuel system of the internal-combustion engine. The nozzle is a precision coupling formed by an injector valve body and an injector valve. The head of the injector valve body is provided with at least one cross sub-orifice and each cross orifice is formed by crossing and collecting of at least two sub-orifices. As the collection of fuel in the sub-orifices of the cross orifice can form intense disturbance, the turbulent kinetic energy is increased and the atomization is improved; as an outlet of the cross orifice is formed by the collection of the sub-orifices, the flow area of the outlet is less than the sum of the outlet areas of all the sub-orifices, the injection nozzle is characterized by improving discharge coefficient like an analogous V-shaped gradually shrinking orifice. In brief, the crossing of the sub-orifices increases the internal flow, improves the turbulent intensity, causes the cross orifice to improve atomization, improves the quality of the mixed gas and leads to rapid, sufficient and perfect combustion, thus being beneficial to the further improvement of the economic performance, discharging performance and kinetic performance of the motor.

A valve device for a fuel injection valve (1), wherein the intersection point (13c) between the center line Z of the valve seat (11) and the apex of a hypothetical cone (13b) formed by extending a seating surface (13) toward the downstream side is positioned inside an aperture (15). Thus, after most of the fuel that has passed through a seat part (13a) converges at the aperture (15), the fuel reaches the upper surface of an injection hole plate (22) and smoothly changes to a flow toward the outer circumferential side, thereby minimizing the fuel pressure loss in this interval. Therefore, in this valve device for the fuel injection valve (1), a decrease in the fuel speed in the section (22b) directly above the injection hole is reduced, and atomization of the fuel spray is promoted.

Vortex chamber combustion system utilizing umbrella-shaped spray

The invention relates to a vortex chamber combustion system utilizing umbrella-shaped spraying, which belongs to the fields of formation and combustion of engine mixing gases. The vortex chamber combustion system utilizing an oil nozzle with an umbrella-shaped spraying has the structural characteristics that the center line of the oil nozzle with an umbrella-shaped spraying way is superposed withthe center line of a main passage so that the air which flows into a vortex chamber from a compression stroke via the main passage turns back along the wall surface of the vortex chamber to form vortex after reaching the vicinity of the head part of the oil nozzle; the direction of the vortex is just along the diffused direction of the umbrella-shaped spraying so as to accelerate oil and gas mixture and improve the combustion. Because the characteristics of short penetrating distance, even circumferential distribution and high granulation of the umbrella-shaped spraying are reasonably utilized, the favorable mixture and combustion can be obtained at lower vortex strength, thereby reducing heat dissipation loss and throttling loss and further improving the heat efficiency of an engine. Experiments on a single-cylinder 195 diesel engine indicate that the power is improved by 10 percent, the oil consumption is reduced by 8 percent, the discharge of NOx is reduced by 10 percent and the discharge of soot is reduced by 20 percent after the vortex chamber combustion system utilizing the oil nozzle with a umbrella-shaped spraying way is adopted.
