1. Anti-fuel vapor lock

The higher the temperature, the faster the fuel (especially gasoline) evaporates, and the easier it is to form air resistance in the oil circuit, resulting in insufficient oil supply or even interruption of the oil supply. Therefore, the fuel filter should be cleaned in time in summer to ensure the smooth flow of the oil path.

Countermeasures:

In order to prevent air resistance, asbestos pads can be used to separate the gasoline pump from the exhaust pipe, or the gasoline pump can be wrapped with a damp cloth to cool down to reduce air resistance. Once the fuel system has air resistance, stop and cool down immediately, and turn the hand oil pump to fill the oil circuit with fuel.

2. Prevent the mixed gas from being too thick

Due to the high temperature, the gasoline is easy to flow, and the flow of gasoline is increased due to the expansion of the metering hole, and the gasoline is easy to evaporate, which causes the mixture to be too rich.

Countermeasures:

The measuring hole should be adjusted small, the position of the accelerator device and the throttle rocker arm should be adjusted, and the oil level of the float chamber should be appropriately lowered to reduce the oil supply.

3. Prevent excessive evaporation of gasoline and water

In the hot summer weather, the evaporation of oil and water will increase. The water in the battery electrolyte evaporates quickly, the liquid level drops quickly, and even the electrode plate is exposed to the liquid level, causing the battery to lose water and early damage.

Countermeasures:

Need to check at any time, pay attention to the fuel tank cap to be tightly closed, but also pay attention to prevent the oil pipe from leaking. For the water level of the water tank, the oil level and height of the crankcase, the brake fluid level in the brake master cylinder, and the electrolyte density and fluid level in the battery should be checked frequently.

4. Anti-braking failure

Brake fluid is easy to evaporate and vaporize in a high temperature environment, forming air resistance in the brake pipeline, and the brake shoe is also easy to ablate, causing brake failure.

Countermeasures:

The brake system should be checked and adjusted in time, and the brakes should be parked to ensure good braking performance on the way down long slopes; if the brake hub is found to be hot, stop and cool down, but do not pour cold water to prevent the brake hub from rupturing.

5. Prevent tire burst

In summer, the road surface temperature is higher, and the use environment of automobile tires is even worse. The hot weather can easily deform the tires and reduce the tensile strength. As for the tire itself, non-standard air pressure, aging of the tire, weakened performance, or the tire rolling onto a hard metal or other hard objects during driving, etc., will cause the car to suddenly puncture.

Countermeasures:

When operating under high temperature conditions, pay attention to the temperature and air pressure of the tires, and check frequently to ensure the specified air pressure standards. Before leaving the vehicle, you should properly reduce the tire pressure, and check the temperature and pressure of the tires in time when you take a break during driving; if you find that there is a lack of air, you should make up in time, and you must not make do with it. If the temperature of the tires of the sanitation garbage truck is too high, do not pour cold water The tire temperature can be lowered by the method, which will cause cracks due to uneven shrinkage of the tread and sidewall rubber layer. You should choose a cool place to park; if you are wading, you should wait until the tire temperature is appropriately lowered before wading to prevent Early damage to tires.

6. Prevent poor lubrication

When the temperature is high, the viscosity of the engine oil will decrease, the oxidation resistance will become poor, resulting in poor lubrication, and even causing failures such as bush burning and shaft holding.

Countermeasures:

The crankcase and gearbox should be replaced with summer lubricating oil, and the quantity and quality of the lubricating oil should be checked frequently and replaced in time. Do not mix lubricants of different brands. Clean the oil filter and radiator in time to ensure smooth oil flow and good heat dissipation, and try to avoid overloading the engine.

7. Anti-car paint damage

The paint surface of sanitation garbage trucks will wear out and wrinkle after long-term exposure. Ordinary beauty waxing has some effects, but because any car wax contains silicon, it will rust the car paint after long-term ultraviolet radiation, leaving a little dark spot. Moreover, the car wax itself does not have the effect of enhancing hardness and anti-ultraviolet rays, and will quickly lose due to high temperature.

Countermeasures:

You should park your car in a cool place when parking. It is recommended to do a good job of sealing the glaze for your car. The car glaze is to seal a layer of protective glaze on the paint surface of the car to prevent the paint surface of the garbage truck from being directly exposed to the outside. At the same time, this layer of protective glaze also has the effect of anti-ultraviolet rays. At present, the price of sealing glaze on the market is generally around 1,200 yuan, and the entire construction process takes about 5 times.

8. Anti-engine deflagration

In the hot summer, the engine is also prone to overheating, and it is not uncommon for the engine to be scrapped due to overheating. The failure rate of the car itself is also greatly increased, and it is prone to spontaneous combustion and deflagration.

Countermeasures:

In order to prevent the engine from overheating at high temperatures, it is necessary to strengthen the maintenance in this area: pay attention to the fan belt not to be stained with oil to prevent slipping, and the belt should be kept as tight as possible. If you are driving for a long distance or when the water temperature is too high, you should park in a cool place to cool down, let the engine run at idle speed, and open the hood to facilitate heat dissipation.
