What are the engine failures in the garbage truck driving? Garbage trucks may present various problems at any time while driving. Garbage truck drivers need to be aware of some necessary fault recognition and processing capabilities in addition to paying attention to the maintenance of vehicles at the same time. The time will not be rushed.
PU resin, also known as polyurethane resin, is a type of synthetic resin that is widely used in the production of inks. It is a versatile material that offers various benefits for ink formulations.
One of the main advantages of using PU resin in ink is its excellent adhesion properties. It forms a strong bond with different substrates, including paper, cardboard, plastic, and metal, ensuring that the ink adheres well to the surface and resists smudging or rubbing off.
PU resin also provides good gloss and transparency, resulting in vibrant and visually appealing prints. It enhances the color intensity and clarity of the ink, making it suitable for high-quality printing applications.
In addition, PU resin offers excellent resistance to water, chemicals, and abrasion. This makes the ink more durable and long-lasting, ensuring that it remains intact even under harsh conditions.
Furthermore, PU resin can be formulated to have fast drying properties, allowing for faster production speeds in printing processes. It also has good flexibility and elasticity, which helps prevent cracking or flaking of the ink film.
Overall, PU resin is a popular choice for ink formulations due to its excellent adhesion, gloss, transparency, resistance, and drying properties. It is commonly used in various printing applications, including packaging, labels, decals, and graphic arts.

First, the engine exhaust color.
1, garbage truck exhaust color blue. In the garbage truck, a large amount of lubricating oil enters the cylinder and can't complete the combustion; sometimes the engine cold starts to emit blue smoke, but when the car is hot, it's okay. It is advisable to go to the 4S store for maintenance.
2. Garbage exhaust color is black. Due to incomplete combustion of fuel. It will cause a drop in power and economic deterioration. It is recommended to go to the 4S shop for maintenance.
3. Garbage trucks are white in color, severe when they are cold, and do not emit white smoke after hot cars. This is because gasoline contains water, and the engine is too cold. At this time, the fuel entering the cylinder is not completely burned, resulting in fog or water vapor generating white smoke. In the winter or rainy season, white smoke is often seen when the car is first started. Once the engine temperature increases, white smoke will increase. This state does not require maintenance.
Second, engine lubrication
1. Lubricant pressure indicator lights up when accelerating. Indicates that the lubricating oil pressure is too low. This may be due to filter plugging, low lubricant, pump failure, and other causes. It is advisable to go to the nearest service station for overhaul. Or the lube oil pressure indicator system has malfunctioned and the indicator light has been lit incorrectly. It is advisable to go to the nearest service station for overhaul.
2, excessive consumption of lubricants. Lubricants have normal consumption in a good condition, but when the vehicle is in poor condition, the exhaust color of the vehicle is blue. This means that the consumption of lubricant oil is too large. The main reason for the consumption of lubricant oil is to enter the combustion chamber to participate in combustion. Or oil leaks. It is advisable to promptly approach the service station for overhaul.
Third, the engine starts difficult
1, cold start difficult, start after the vibration, vibration at low speed. It may be spark plug failure or ignition timing is too early. It is advisable to go to the nearest service station for overhaul.
2. It is difficult to start when the temperature is low in winter. The main reasons are: low temperature, low gasification rate of fuel; difficulty in starting the mixer due to thinning and non-flammability; large viscosity of the lubricating oil, increased engine operating resistance and difficulty in starting; the chemical reaction of the battery electrolyte is slow, resulting in start-up Insufficient power output, insufficient starter power, and insufficient ignition voltage make it difficult to start the engine.
Garbage trucks should warm up the engine before starting in the cold season to avoid difficulties in starting at low temperatures in winter.
Fourth, the generator is unstable
1. The throttle body of the engine is dirty or sloppy. When the throttle valve and the idle valve of the engine valve body are heavily fouled, the engine will experience idling too low, poor stability, or no idle, and the throttle valve will be stuck when refueling. It is generally advisable to clean the throttle body whenever the vehicle is about 20,000 kilometers. After cleaning, it should be set up through the diagnostic device to make it work normally.
2, the engine jitter is serious, the fault indicator will occasionally shine. The reason is that unclean fuel has caused contamination or clogging of the oil supply system. The use of dirty fuel can cause fuel supply, ignition, and emissions system contamination, which in turn can cause engine fault indicators to light up and varying degrees of engine vibration.
The solution is to thoroughly clean the contaminated system, continue to add stable gasoline, and add a fixed amount of oil cleaner.
5. Boiling of engine coolant during driving
Generally, it is caused by the reason that the garbage truck is driven at a low speed for a long time under a large load, the circulation of the cooling system is poor, and the heat radiation of the radiator is not good. It is possible to park the car for a while and wait for the engine coolant to cool down before proceeding. However, it must not be cooled by cooling the engine around the cold water.
6. When the garbage truck accelerates rapidly, the speed cannot be raised. When the garbage truck is running, the acceleration and normal acceleration of the garbage truck are normal. When the speed is accelerated, the speed cannot be raised immediately, regardless of overtaking. The possible reason is that due to the failure of the engine fuel supply system, the oil pressure, fuel injection amount, and ignition timing do not meet the specifications, and the spark plug and the high-voltage line have failed.
