First, fire engine oil deterioration and Oil Filter is not smooth
Different grades of oil will change during use. After the vehicle has traveled a certain distance (Gallery Forum), performance deteriorates, which may cause various problems for the engine. In order to avoid the occurrence of these faults, the vehicle should be regularly replaced with the conditions of use, and the amount of oil should be moderate, generally between the upper and lower limits of the oil gauge.
When the oil passes through the pores of the oil filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged, the oil cannot smoothly pass through the filter element, and it will burst through the filter element or open the safety Valve and pass through the bypass valve, which will still bring dirt back to the lubrication area, which will accelerate engine wear and increase internal pollution. Therefore, regular replacement of oil filter elements is equally important.
Reminder: Do not add less oil, but do not add more, not more expensive brand-name synthetic oil is better, for your car's oil is the best.
Does not regularly maintain the engine of fire engines
Second, the intake pipe is dirty
If the vehicle is often driving in a road with a lot of dust and poor air quality, you should pay attention to cleaning the air intake pipe to ensure the smooth flow of air. The intake pipe is very important for the normal operation of the engine. If the intake pipe is dirty, the efficiency will decrease, and the engine will not be able to operate within the normal output power range, which will aggravate engine wear and aging.
Reminder: Try to avoid dusty areas as much as possible. At the same time, the air conditioning grid should also pay attention to replacement.
　　 Third, the Air Filter plug
The intake system of the engine of a fire engine is mainly composed of an air filter element and an air intake duct. According to different use conditions, to regularly clean the air filter, the method can be used to blow high pressure air from the inside, the dust in the filter element is blown out. Since the air filter is paper, it should be noted that the pressure of the air should not be too large when blowing so as not to damage the filter element. Air filter cartridges should be replaced after cleaning three times. The cleaning cycle can be determined by the air quality of the daily driving area.
Reminder: It is also important to purchase genuine factory air filters that are supplied by good quality manufacturers.
Fourth, usually people always like to invest a lot of money in the modification, but it is easy to ignore the maintenance of the engine on schedule. According to experienced auto technicians, in the fire trucks they have repaired, the failure caused by poor maintenance of the engine accounts for 50% of the total failures. It can be seen that engine maintenance plays a crucial role in extending the service life of the vehicle. Of course, it will also reduce unnecessary losses for you.
Reminder: It is not only necessary to carry out maintenance of the engine during the regular maintenance period. When driving through some areas that are particularly wet or have particularly large dust, all Engine Parts must be checked and maintained.
V. Excessive crankshaft sludge
During the operation of the engine of the fire engine, the high-pressure unburned gases, acid, moisture, sulfur and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the Piston ring and the cylinder wall, causing the metal to wear with the parts. The powders are mixed together to form sludge. A small amount of sludge can be suspended in the oil and when it equates to a large amount, it precipitates out of the oil, clogging the filter and the oil hole, causing the engine to be difficult to lubricate, thereby aggravating engine wear. In addition, when the oil is oxidized at a high temperature, a paint film and coke deposits are formed on the piston, so that the engine oil consumption increases and the power drops. In severe cases, the piston ring is stuck and the cylinder is pulled.
Reminder: To reduce the production of sludge, it is very necessary to use high-quality fuel, so it is recommended that owners refuel as far as possible to the right gas station. In addition, the use of quality lubricants and replacement of oil filters and oil filters according to the manufacturer's maintenance schedule is also critical. In addition, please check your own car's oil level regularly.
6. Poor maintenance of fuel system
The maintenance of the fuel system includes replacing the Fuel Filter, cleaning the carburetor or fuel nozzle, and the oil supply line. When fuel is supplied to the combustion chamber through the oil passage, it will inevitably form colloid and carbon deposits. It will deposit in oil passages, carburetors, fuel nozzles and combustion chambers, disturbing the flow of fuel and destroying normal air. The fuel ratio causes poor fuel atomization, causing engine performance problems such as engine vibration, knocking, unstable idling, and poor acceleration.
Reminder: Periodically remove fuel tank deposits, remove deposits from the fuel filter screen, and properly maintain the air cleaner, fuel tank, and piping. When cleaning the engine fuel system, use engine-free decontamination agent as it is free to remove. The cleaning agent does not require dismantling the fuel system . On the one hand , it can play a role in thoroughly cleaning the fuel system. On the other hand, it is beneficial to protect the engine's fuel system.
Seven, poor cooling system
People pay special attention to the lubrication system for the maintenance of the engine of the fire engine, and rarely pay attention to the cooling system. Little does they know the most common failures of fire engine engines, such as piston pull, knocking, internal leakage of cylinder punch, serious noise, deceleration of acceleration, etc., are due to the abnormal working temperature of car engine, excessive pressure, and the status of cooling system Bad result. The poor condition of the cooling system will directly lead to the engine not being able to work at the normal temperature, which will result in the above-mentioned serious failure phenomenon.
Reminder: How to maintain the cooling system? The traditional method is to put the water in the water tank to end, add antifreeze and water, but in this case there is a lot of scale in the cooling system is not clean, and the Water Pump , water jacket, tube The debris in the road can't be discharged. Therefore, it is necessary to regularly use tanks with powerful and efficient cleaning agents to clean rust and corrosive substances in water tanks and cooling systems, and then add appropriate antifreeze and clean water. This will ensure normal engine operation and extend the overall life of the tank and engine.
Eight, water tank rust, scaling
Fire engine tanks are rusty and fouling is the most common problem. The rust and scale will limit the flow of coolant in the cooling system, reduce the heat dissipation, cause the engine to overheat, and even cause damage to the engine. Coolant oxidation also forms acidic substances that corrode the metal parts in the tank, resulting in breakage and leakage of the tank. Regular use of water tanks for powerful and efficient cleaning agents to clean water tanks to remove rust and scale from them will not only ensure normal operation of the engine, but also extend the overall life of the tank and engine.
Reminder: To avoid the generation of scale, we must pay attention to the choice of tank coolant. Many car owners do not attach importance to the use and quality of coolant. Normally only ordinary water is added to the tank. The most common problems in cooling systems are rust, scaling, and corrosion. The main reason for this is the lack of good antifreeze. Good antifreeze not only has a low freezing point, but also has various other added ingredients that can inhibit foam, rust, electrolysis, and anti-scale, and so on, so it is important to remind the majority of cars to choose the coolant that is beneficial to the tank.
Finally, fire truck manufacturers remind users of the majority of fire engines to use the correct method when servicing the fire truck. Do not make the service life of the fire truck greatly reduced due to incorrect maintenance methods.
