Abstract

The invention provides a fuel nozzle and an engine. The fuel nozzle comprises a shell body and a spraying spout body, wherein the shell body comprises an outlet end, the spraying spout body is installed at the outlet end of the shell body, a spraying spout cavity is formed inside the spraying spout body, the spraying spout cavity comprises a conical section and a spraying-out section, the spraying-out section is connected with the small-diameter end of the conical section, the taper angle of the conical section is an acute angle, and the length of the spraying-out section is larger than 0.2mm. The fuel nozzle enables diesel to meet operation conditions of a turbine engine. When the fuel nozzle is used for the turbine engine, the turbine engine using the diesel operates normally, the turbine engine gets rid of the restriction of aviation kerosene, the combustion application range of the turbine engine is widened, the adaptability of the turbine engine is obviously improved, and oil cost of the turbine engine is correspondingly lowered. Due to the fact that the fuel nozzle enables the fuel oil to be better scattered in an atomization mode, the engine achieves a better combustion effect and increases power output when using the aviation kerosene.

Description

technical field [0001] The invention relates to the field of engine equipment, more specifically, to a fuel nozzle and an engine. Background technique [0002] In the prior art, piston engines use gasoline or diesel oil as fuel, while turbine engines use aviation kerosene as fuel. There are many differences between aviation kerosene and diesel oil, such as different molecular weights and different ignition points, which lead to different combustion characteristics of aviation kerosene and diesel oil in the engine. [0003] Existing turbine engines cannot run properly on diesel fuel, leaving turbine-equipped vehicles to run on aviation kerosene. Compared with aviation kerosene, diesel oil has the characteristics of large output and low price, and is suitable as a fuel for engines, especially for heavy machinery and vehicle engines. Therefore, the fuel cost of vehicles using turbine engines will be lower than that of piston engines. The vehicle is high, and aviation kerosene...
