喷油器与喷油嘴是柴油发动机的精密偶件,其正确组装、试验、安装与否对发动机的动力性能和经济性能影响很大。下面以东方红-4125型发动机为例,谈谈怎样正确组装、试验、安装喷油器。 一、清除防锈油 新的喷油嘴在使用前,必须首先清除防锈油。这是因为防锈油粘度较大,常温下不易被柴油溶解,装到车上使用时,就会影响喷雾,而且容易焦住喷油嘴。因此,可用加热法清除防锈油,将喷油偶件放到柴油中加热到80～100℃,然后放到清洁油内进行清洗。清洗的方法是:在柴油中一手拿喷油
Injectors and injectors are precision diesel engine parts, the correct assembly, testing, installation or not on the engine’s dynamic performance and economic performance of great influence. The following Dongfanghong -4125 engine, for example, talk about how to properly assemble, test, install the fuel injector. First, remove the anti-rust oil New nozzle before use, you must first remove the anti-rust oil. This is because the larger the anti-rust oil viscosity, not easily dissolved at room temperature diesel, loaded into the car when used, it will affect the spray, and easy to focus on the nozzle. Therefore, the heating method can be used to remove anti-rust oil, the fuel injection couple into diesel heating to 80 ~ 100 ℃, and then placed in clean oil for cleaning. Cleaning method is: one hand in the diesel fuel injection
