Abstract

The invention discloses a diesel oil circuit heating device, an oil circuit assembly and a diesel engine containing the device, and relates to the technical field of vehicle heating devices, and has the characteristics of high thermal efficiency, fast heating speed, easy refitting, and dry-burning without melting the tube , It is safe and reliable to use. The technical solution adopted is: the diesel oil circuit heating device includes: a first control circuit, a second control circuit, at least one heating wire assembly, a heating rod assembly, and a temperature control switch. The first control circuit controls the operation of the heating wire assembly, and the temperature control One end of the switch is connected to the first control circuit, and the other end is connected to the second control circuit; the second control circuit and the temperature control switch control the operation of the heating rod assembly. The diesel oil circuit assembly includes fuel tank oil suction pipe, oil pipe, coarse filter, fuel delivery pump, fine filter and the above-mentioned diesel oil circuit heating device. A diesel engine includes the above-mentioned diesel oil circuit assembly. The embodiment of the present invention is mainly used in the heating of automobile diesel oil circuit.

Description

technical field [0001] The invention relates to the technical field of vehicle heating devices, in particular to a diesel oil circuit heating device, an oil circuit assembly and a diesel engine including the device. Background technique [0002] A diesel engine is an engine that burns diesel to obtain energy release. Although a diesel engine has the advantages of better thermal efficiency and economy, but because the fuel it uses is diesel, which is more viscous than gasoline, when the temperature is low, it will Problems such as thickening, waxing, and clogging of oil pipes occur in diesel oil, which make the diesel engine unable to start. [0003] In order to solve the problem that diesel vehicles cannot start due to cold weather, the following two methods are generally adopted in the prior art; the first is to replace the diesel with a lower condensation point; the second is to add diesel oil to the diesel oil circuit for heating device. Among them, the cost of replacin...

Problems solved by technology

Among them, the external heating type is to install the heater on the outside of the fuel tank, oil pipe, coarse filter, and fine filter, and heat from the outside to the inside. Although this heating method is relatively safe, it has low thermal efficiency and slow heating speed. , The power consumption of the battery is large, which shortens the service life of the battery

The internal heating type inserts the fast-heating heater directly into each component of the oil circuit. Although it overcomes the problem of the slow heating speed of the external heating type heater, this kind of fast-heating device requires the heater to heat up in a few seconds. Larger heat is generated in the bell, which makes the diesel wax melt instantly. If it is not used properly, it is easy to cause the problem of melting the diesel oil pipe, which seriously affects the safety of the car.
