Embodiment Construction
[0018] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0019] The invention provides an oil-air mixing system with side-mounted oil supply and double-impeding wall diversion, which is suitable for opposed piston engines. Such as figure 1 As shown, the system includes a combustion chamber and a multi-hole injector 6 placed laterally beside the combustion chamber. Since it is an opposed piston, the upper and lower pistons have the same structure, so the lower combustion chamber is mainly marked in the figure. The arrows in the figure indicate the flow direction of oil and gas. The combustion chamber is constituted by the shared space of the upper piston body 1 and the top of the lower piston body. The combustion chamber is an opposed combustion chamber, and its shape is a deep pit type combustion chamber in a broad sense.
[0020] The side of the multi-hole fuel injector 6 is placed on one side of the combus...

The invention discloses an oil-gas mixing system with side-mounted oil supply and double-impeding wall diversion, which is suitable for opposed piston engines; There is a guide arc on the top; the guide arc is used as the landing point of the oil beam on the lateral wall, and the aperture of the multi-hole injector is designed to ensure that the split length of the oil beam sprayed from the oil injection hole is longer than that from the oil injection hole to the lateral wall. The distance of the wall impact point of the oil beam makes the injected fuel first collide with the guide arc, forming wall jet stripping, and then deflects to the center of the deep pit of the combustion chamber, and exists mainly in liquid state before the collision; the guide arc is far away from the A diversion pit is arranged on one side of the deep pit of the combustion chamber. The use of the invention can improve the space utilization rate, effectively alleviate the disadvantages of short combustion duration, insufficient combustion and high emission pollution of the two-stroke engine, and make the oil and gas quickly form a flammable mixture in the cylinder to realize rapid combustion.
Description
technical field [0001] The invention relates to the technical field of an oil-gas mixing device, in particular to a side-mounted oil-supply double-blocking wall-guiding type oil-gas mixing system. Background technique [0002] As countries all over the world promote their own industrialization and development, while greatly promoting the rapid growth of their own economies, they also bring huge challenges to global environmental protection. The requirements of domestic and foreign policies and regulations are becoming more and more stringent, and more and more voices are turning to new energy power, which has pushed fuel-powered engines to the forefront. However, there are still many technical problems in new energy that are difficult to overcome in a short time. The power technology has not reached the point where there is no way out, and the engine will develop towards a trend of smaller size, lighter weight and higher specific power. The opposed piston engine can use the...
