AI Technical Summary

Technical Problem

How to accurately determine whether the cooling pipe is ruptured and prevent engine overheating and safety hazards.

Method used

Through the multi-layer logic judgment method, it is determined whether the water temperature in the cooling pipe exceeds the preset temperature value, and whether the rising temperature within the preset time exceeds the preset value; combined with the determination of whether the engine is operating under high load conditions, the cooling pipe is confirmed to be broken through the temperature detection of the exhaust system.

Benefits of technology

Accurate judgment of cooling pipe rupture is achieved, misjudgment is reduced, and the safety and reliability of the engine is improved.

Abstract

The invention relates to the technical field of engines, and discloses an engine device, a cooling pipe fracture detection method thereof and a vehicle. The method comprises the steps that whether the water temperature in a cooling pipe exceeds a first preset temperature value or not is judged; according to the fact that the water temperature in the cooling pipe exceeds the first preset temperature value, whether the rising temperature of the water temperature in the cooling pipe in the first preset time exceeds a preset rising temperature value or not is judged; according to the fact that the rising temperature of the water temperature in the cooling pipe in the first preset time exceeds a preset rising temperature value, whether the engine device operates under the high-load working condition or not is judged; according to the condition that the engine device does not operate under the high-load working condition, whether the temperature of the preset position of the exhaust system in the engine device continuously exceeds a second preset temperature value within a second preset time and a preset duration or not is judged; and according to the fact that the temperature of the preset position of the exhaust system in the engine device continuously exceeds the second preset temperature value within the second preset time and the preset duration, it is judged that the cooling pipe breaks.
