Problems solved by technology

[0002] At present, most of the reversing fans used in diesel engines are hydraulic reversing fans and non-hydraulic reversing fans. The existing hydraulic reversing fans need manual fan reversing or timing reversing, which is low in automation, high in cost and poor in reliability. Manual operation, poor adaptability; non-hydraulic reversing fan control means manually activated reversing or timing reversing, low degree of automation, poor adaptability, high energy consumption, the existing two reversing fans only have positive and The two working modes are reversed, and automatic control cannot be performed according to the temperature of the engine

Embodiment Construction

[0013] The present invention will be further described in detail below in combination with specific embodiments. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0014] Such as figure 1 Shown, the control method of described a kind of diesel engine reversing fan is characterized in that: comprise the following steps:

[0015] S1: Temperature calculation management method: take the maximum value of the diesel engine coolant temperature and lubricating oil temperature (oil temperature - deviation value) (considering the difference between the engine oil temperature and coolant temperature, so the difference between the engine oil temperature and the water temperature is compared before comparison ), the set deviation value is 25°C, and the calculated lubricating oil temperature value is: engine oil temperature -25°C; and when one of the two sensors of the water temperature sensor...

Abstract

The invention discloses a diesel engine reversing fan control method. The control method is characterized by comprising a temperature calculation management method, a gear strategy setting method anda gear running time management method. The control method has the advantages of being high in automation degree, multiple in fan gears, high in stability, energy-saving and environment-friendly, and capable of reducing fuel consumption.

Description

technical field [0001] The invention relates to the field of engines, in particular to a method for controlling a reversing fan of a diesel engine. Background technique [0002] At present, most of the reversing fans used in diesel engines are hydraulic reversing fans and non-hydraulic reversing fans. The existing hydraulic reversing fans need manual fan reversing or timing reversing, which is low in automation, high in cost and poor in reliability. Manual operation, poor adaptability; non-hydraulic reversing fan control means manually activated reversing or timing reversing, low degree of automation, poor adaptability, high energy consumption, the existing two reversing fans only have positive and The two working modes are reversed, and automatic control cannot be performed according to the temperature of the engine. [0003] The disclosure of the above background technical content is only used to assist in understanding the inventive concepts and technical solutions of th...
