What happens if the engine oil in a car is not changed?

Failure to change the engine oil in a car can lead to oil deterioration, reducing its lubrication effectiveness. When the engine operates, internal components may not receive proper lubrication, resulting in wear and tear on the engine parts. Benefits of changing engine oil: Lubrication and friction reduction: Separates the surfaces of relatively sliding parts. Cooling: Assists the radiator in cooling the engine. Cleaning: Flushes away dirt generated on the working surfaces of parts. Sealing and leakage prevention: Reduces gas leakage and prevents external contaminants from entering. Sealing and rust prevention: Lubricating oil adheres to the surfaces of parts, preventing contact with water, air, acidic substances, and harmful gases. When the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston rings, connecting rod, and crankshaft bearings, this load is transmitted through the bearings' lubrication, cushioning the impact load.

How often should a car that is not frequently used be started?

It is recommended to start the car once a week or at least every two weeks. There are significant hazards associated with not starting a car for extended periods. Long-term parking can lead to issues such as battery depletion, tire blowouts, and oil sedimentation. For vehicles that are parked for long durations, it is advisable to start and drive them once a week if possible. This practice helps recharge the battery, ensures even tire pressure distribution, and most importantly, allows the engine oil to better adhere to the internal components of the engine, which is crucial for vehicle maintenance. If a vehicle remains idle for a long time, the oxidation of engine oil can become quite severe. Oxidized oil first affects the lubrication efficiency of the engine and transmission, and secondly, acidic substances can corrode mechanical parts. The longer a vehicle is left unused, the more severe the oil oxidation becomes, leading to increased dry friction between the cylinders and pistons upon restarting, accelerating component wear and making the engine harder to start. When a vehicle is stationary, the oil in the seals and pipelines remains stagnant, causing uneven pressure distribution around the seals. The side under greater pressure will experience more deformation of the seal. The longer the vehicle remains parked, the worse the seal's ability to recover becomes, eventually leading to a permanent loss of elasticity. Electronic components and connectors in vehicles are particularly susceptible to moisture, humidity, and corrosion, which can cause malfunctions. The likelihood of these components becoming damp increases significantly in parked vehicles, and the risk of failure rises with the duration of inactivity.

Why Does the Car Body Shake After Replacing the Battery?

The reasons for car body shaking after replacing the battery include severe engine carbon buildup, ignition system failure, and oil pressure issues. Below are the specific causes: Severe Engine Carbon Buildup: Engine carbon buildup is the main cause of car shaking. When there is excessive carbon buildup inside the engine, the gasoline sprayed by the fuel injector during a cold start will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts, which can easily cause shaking. Cleaning the carbon deposits can solve the problem. Ignition System Failure: Excessive carbon buildup on the spark plugs or overly large ignition gaps can lead to ignition failure. Replacing the spark plugs can resolve this issue. Oil Pressure Issues: Abnormal fuel pump pressure or incorrect readings from the intake pressure sensor can cause poor fuel pump performance, leading to car body shaking.

What is the difference between integral active steering and variable steering ratio?

Integral active steering and variable steering ratio differ as follows: Different principles: The principle of integral active steering is to use a centralized control system that receives various dynamic driving signals from the vehicle, then comprehensively analyzes and outputs an appropriate steering angle. This drives the nut to move the lead screw axially, causing the rear wheels to turn slightly in the same direction as the front wheels, thereby enhancing stability during high-speed cornering. Different effects: The larger the variable steering ratio, the greater the rotation of the steering wheel required to achieve a specified turning distance for the wheels. With the same steering assistance, a larger steering ratio means less force is needed to rotate the steering wheel, making it more effortless. Different development trends: Variable steering ratio mainly develops in two directions: one is the mechanical variable steering ratio system, and the other is the electronic variable steering ratio system.

What are the reasons for a motorcycle not starting in first gear?

Motorcycle not starting in first gear is caused by low temperature and idle speed issues. Motorcycle low temperature: If you use the kick starter, the low temperature in winter makes it difficult to start. In this case, you should pull the choke (also known as the choke valve). Normally, it should be pushed all the way down. During cold starts in winter, it should be pulled to the top. After the engine starts, leave it for about 15 seconds and then adjust it to the middle position. When the motorcycle has warmed up, return it to the normal state—pushed all the way down. This process usually takes about three to five minutes. Motorcycle idle speed issue: Sometimes the motorcycle doesn't start due to low idle speed. In summer, the tachometer needle should point to one mark or slightly more. In winter, adjust it to between one and a half and two marks.

What is the working principle of the transmission oil cooler?

The working principle of the transmission oil cooler is that when the engine is running, the water pump rotates accordingly to increase the coolant pressure, forcing the coolant to circulate. The circulating coolant carries away heat from components such as the engine block, cylinder liners, and cylinder head. When the coolant temperature has not reached the thermostat's opening temperature, the already cooled coolant flows into the radiator's water chamber and is pumped back into the engine block by the water pump to rejoin the cooling cycle. Disadvantages of the transmission: During acceleration, the transmission does not skip gears. The harder the accelerator is pressed, the more the transmission gears idle and slip, sometimes making it difficult to downshift or upshift. The shifting piston may wear out due to excessive impurities in the transmission oil, preventing the transmission oil from releasing pressure and thus making gear shifting impossible. Therefore, it is essential to change the transmission oil regularly. There may also be jerky shifts and impacts. Advantages of the transmission: Although the transmission has been subject to various complaints from car owners, its durability is still acceptable. Common transmission issues, aside from design and technical imperfections, are largely due to the driving habits of the owners or prolonged driving under harsh road conditions. Therefore, it is reasonable to view transmission problems rationally, develop good driving habits, and perform regular maintenance and repairs.
