Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a method that can use an external AC and DC power supply to realize the hot start of the engine. When there is no external power supply, it can automatically switch to use the electric energy of the engine itself to heat some specific parts separately. or a set of heat preservation devices to solve the problems of difficulty in starting the fuel engine under low temperature conditions, abnormal mechanical wear of the fuel engine, waste of energy and pollution of the environment

Embodiment Construction

[0013] The working principle and automatic control of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Figure 1 shows an embodiment of the invention. The preheating device before starting in this embodiment is composed of a heating element, a leakage protector, a switch, an AC / DC changeover switch, an external power supply, and the power supply of the equipment itself; On the heating parts such as oil device, engine body, oil pan, etc., induction devices are installed inside each heating part of the fuel engine; the induction devices are respectively connected to the temperature control device by wires, and then connected to their own power supply to form a preset Heat device automatic control circuit.

[0015] In practical applications, the number of heating elements can be set according to the needs of the situation, and the number of temperature sensing devices and temperature control devices can ...

Abstract

The invention discloses a preheat device before the fuel machine starting that could use extra AC or the electric power the fuel machine carried itself to realize automatic control. It is made up of heating component, earth leakage protection device, switch, power supply and wire. The benefit of the invention is that: realizing fuel machine preheating in a short time, thus, it solving the problem of fuel machine is difficult to start under low temperature condition, abnormal mechanical wear, energy wasting and environment pollution.

Description

technical field [0001] The present invention relates to a preheating device for a fuel engine, in particular to an automatic controlled preheating device for each fuel supply device, machine body, engine oil pan, etc. device. Background technique [0002] Under low temperature conditions, it is difficult to start a fuel engine. Cold start causes abnormal mechanical wear of the engine and reduces the service life of fuel machinery. Especially for diesel engines, the low temperature of diesel entering the cylinder can lead to poor atomization and incomplete combustion. The energy also pollutes the environment. The existing technology uses the waste heat of the fuel engine to heat the fuel engine, which cannot realize the hot start of the car. However, the technology of using its own system power supply to heat the fuel engine is limited by factors such as materials and electric energy, and cannot solve the above problems. ...
