Problems solved by technology

[0006] At present, in order to solve the problem that under the condition of cold weather, diesel oil is prone to wax formation and solidification, which makes it difficult for diesel oil to flow in the oil pipeline, and the mixing of water and debris in the oil pipeline will easily lead to oil passage blockage and difficulty in starting the engine. , interruption of fuel supply, forced parking and other phenomena, these phenomena not only reduce the performance of the diesel engine of the range extender of electric vehicles, but also affect people's normal travel problems; also in order to solve the problem of insufficient diesel combustion in low temperature environments , indirectly cause waste of energy, and produce pollution emissions and increase greenhouse effect gases. The main way to solve the above problems is to choose diesel oil with a corresponding temperature rating, or to use electric heating tubes that rely on batteries to heat and insulate oil pipelines, which not only consumes Electricity is high and heating is inefficient
