Problems solved by technology

[0002] The fuel supply system of the diesel engine is an important device of the diesel engine. Adding a diesel preheating device to the fuel supply system is to solve the problem that after the diesel engine is shut down for a long time in winter, the fuel tank and the oil pipe will be waxed, which will make the engine oil solidify and make it difficult to start. Therefore, fire is often used to bake the fuel tank and the oil circuit, causing the fuel tank to explode and catch fire, causing damage to personnel and the diesel engine; Diesel is expensive, which increases the cost of driving; at the same time, the incomplete combustion of diesel causes environmental pollution and economic losses
