Problems solved by technology
However, because the preheating method is continuous, it will lead to excessive preheating. At the same time, the technology adopts 3 concave cylinder structures, which are respectively matched with 3 high-pressure oil pipes. In addition, because the installation position is far away from the fuel injection gun, When the diesel engine runs in a low temperature environment, the temperature of the hot fuel will drop when it flows through the pipeline, which will affect the combustion quality of the diesel in the cylinder

The invention provides an oil-saving device for removing black smoke of a diesel engine. A fuel pre-heating device of the diesel engine is a device which is used for intermittently pre-heating diesel oil which flows through a pipeline and arranged on the outer pipe wall of a high-pressure oil pipe of the diesel engine. The pre-heating device is characterized by being formed by mounting a heating wire on a mica sheet and arranging a chip into a groove of a metal shell, wherein a temperature controller is mounted at the middle part of an upper cover board so that diesel oil can be effectively pre-heated in an intermittent pre-heating control manner. Therefore, the burning quality of the diesel oil is improved, the oil is saved, the black smoke is removed, and the problems that the diesel oil is difficult to start and operate at a low temperature in winter can be further solved.
Description
Technical field [0001] The invention belongs to a device for preheating fuel in a diesel engine, so as to improve the utilization rate of fuel, and realize the purpose of energy saving and black smoke elimination. Background technique [0002] The combustion effect of a diesel engine is not only related to the power of the diesel engine, but also affects the quality of the air environment. In the existing technology, the manufacturers of diesel engines use turbocharger and diesel electronic injection technology to solve the problem of fuel in the cylinder. The quality of the combustion. Diesel fuel cannot be completely burned in the cylinder and a large amount of carbon is produced, which causes premature damage to engine parts and reduces the service life of the engine. The reason for the above problem is that the fuel entering the combustion chamber of the diesel engine is always in a cold state, and then injected into the cylinder through the fuel injection gun will reduce th...
