Embodiment 1

[0026] A diesel engine low-temperature starting preheating device, using a diesel engine low-temperature starting control system, the preheating device includes: a heating body arranged on the intake pipe of the diesel engine, preferably the heating body includes an electric heater 1 and an electric glow plug 2, and the electric heater 1 and the electric glow plug 2 are all fixedly connected with the diesel engine intake pipe.

[0027] In order to ensure the effective operation of the low-temperature starting device of the diesel engine, and to ensure the reliable performance of the heating body, safe use, and convenient installation and connection, the low-temperature starting device of the diesel engine in this embodiment also includes a control system, which is effective for the low-temperature starting device of the diesel engine. control and real-time detection.

[0028] The following focuses on the description of the diesel engine low temperature start control system:

...

Embodiment 2

[0034] The difference from Embodiment 1 lies in the connection of the control system and the number of electric heaters 1 and electric glow plugs 2 . This example refers to figure 1 , taking two electric heaters 1 and eight electric glow plugs 2 as examples, the description is as follows:

[0035] First of all, it should be pointed out that the detection device of this embodiment is preferably a detection circuit, and the detection circuit is concentrated on one circuit board; the reminder device of this embodiment is preferably a buzzer 3 .

[0036] According to the needs of users, the company has developed a diesel engine low-temperature starting device to realize the fast and smooth starting of the diesel engine in a low-temperature environment of (-35~-40) °C. The device includes 2 square electric heaters 1 and 8 cylindrical electric heaters. Heating plug 2, 4 batteries and connecting wires, etc. Among them, 4 batteries are the power supply of the system. There is a spec...

Abstract

The invention discloses a diesel engine low-temperature starting control system. The diesel engine low-temperature starting control system comprises a control device, wherein the control device controls an electric heating body to reliably preheat a diesel engine gas inlet system and comprises a relay and a circuit breaker; an input end of the relay is connected with an output end of a power supply; an output end of the relay is connected with an input end of the circuit breaker; and an output end of the circuit breaker is connected with the electric heating body. The invention further discloses a diesel engine low-temperature starting device which uses the low-temperature starting system. The invention also discloses a diesel engine low-temperature starting control method. Circuits of electric devices can be connected simply, conveniently and reliably, and the electric heating body can also be controlled effectively. A detecting device and a reminding device are added in the control system, short-circuit or open-circuit hidden troubles of the electric heating body in a working process can be detected in time, and the circumstance that broken pieces enter a cylinder to severely damage a diesel engine after the electric heating body is damaged is avoided.
