What causes the diesel engine to boil?
Diesel engine "boiling" refers to the phenomenon of boiling caused by the coolant temperature being too high, which is usually accompanied by problems such as steam coming out of the water tank, power drop or even flameout. This failure not only affects the normal operation of the equipment, but may also damage engine components. The following are common causes and solutions for diesel engine boiling, compiled based on relevant discussions on hot topics on the Internet in the past 10 days.
1. Common causes of diesel engine boiling
| Cause classification | Specific performance | Related hot search topics |
|---|---|---|
| Cooling system failure | The water pump is damaged, the thermostat is stuck, and the water tank is clogged. | #Truck Water Tank Maintenance Misunderstanding# |
| Poor heat dissipation | Broken fan belt, dirty radiator | #Engineering Machinery High Temperature Warning# |
| Improper operation | Long-term overload operation and insufficient coolant | #Agricultural Machinery Operation Specifications# |
| mechanical failure | Cylinder gasket destroyed, injection timing error | #DIESEL ENGINE MAINTENANCE TIPS# |
2. Analysis of recent hot-related events
1.High temperatures in summer cause centralized faults: According to data from a short video platform, videos related to "diesel engine high temperature" have been played 12 million times in the past seven days. Agricultural machinery operators in Shandong, Henan and other places reported that the boiler failure rate increased by 30% year-on-year.
2.Counterfeit coolant incident exposed: An e-commerce platform removed 5 low-quality antifreezes from the shelves. Tests showed that their boiling points were only 85°C (the standard should be above 110°C), which directly led to many diesel engine boiling accidents.
| Brand involved | Defect indicators | Number of consumer complaints |
|---|---|---|
| XX brand coolant | Boiling point 85℃/freezing point -10℃ | From 47 |
| YY long-lasting antifreeze | Exceeding corrosiveness | From 32 |
3. Prevention and solutions
1.Daily check points:
2.emergency measures:
| Symptom level | Disposal method | taboo behavior |
|---|---|---|
| The water temperature gauge is close to the red line | Stop immediately and idle to cool down | Add cold water |
| Boiling has occurred | Turn off the flame and wait for natural cooling | Force open the water tank cover |
4. Technology development trends
The intelligent cooling system that has recently been hotly discussed in industry forums has become a new focus. The newly released electronically controlled water pump technology of a certain brand can achieve:
According to statistics, the failure rate of diesel engines using intelligent cooling systems can be reduced by 60%, but the modification cost is about 2,000-5,000 yuan, and it is currently mainly used in high-end models.
Summarize:Diesel engine boiling is the result of multiple factors. The recent high temperature weather and the problem of counterfeit parts have aggravated the failure. It is recommended that users use regular coolant, regularly maintain the cooling system, and upgrade the intelligent temperature control device when necessary. When signs of boiling appear, be sure to operate in accordance with regulations to avoid secondary damage.
