What Causes the Squeaking Noise When Driving Over Bumps?

Introduction to the causes of squeaking noise when driving over bumps: The shock absorber is malfunctioning, mainly due to collisions between the shock absorber and the leaf spring, frame, or axle, damage or detachment of rubber pads, deformation of the shock absorber dust cover, or insufficient oil. The cause should be identified and repaired accordingly. Below is an introduction to shock absorbers: 1. Meaning of shock absorbers: Shock absorbers are wear-prone components during vehicle use. Their performance directly affects the smoothness of the ride and the lifespan of other parts, so they should always be kept in good working condition. 2. Shock absorber issues: After confirming that the shock absorber is faulty or ineffective, first check for oil leakage or signs of old leakage.

What is the SN grade of engine oil?

SN is the second-grade engine oil, while SP is currently the highest-grade engine oil. Engine oil grades are represented by a combination of two letters. The "S" series represents oil for gasoline engines, with general specifications ranging from SA to SP. Each subsequent letter indicates better performance than the previous one, and the further back the letter is in the alphabet, the higher the quality grade. In international brands, engine oil grades are mostly above SF. The following are characteristics of engine oil: 1. Lubricity: The ability of engine oil to reduce friction, slow down wear, and prevent metal sintering under various conditions is called the lubricity of the engine. 2. Low-temperature operability: The performance of engine oil to ensure easy starting and reliable oil supply under low-temperature conditions is called the low-temperature operability of engine oil. 3. Viscosity-temperature characteristics: The property of lubricating oil to change viscosity due to temperature changes is called viscosity-temperature characteristics.

Do Electronic Eyes Capture Motorcycle Violations?

Electronic eyes do capture motorcycle violations. The following are common point-deduction behaviors: 1. Running a red light: 6 points deducted. 2. Drunk driving: 12 points deducted. Depending on the vehicle driven and whether an accident occurred, penalties may include a 5-year, 10-year, or lifetime ban from reapplying for a driver's license. 3. Not wearing a seatbelt: 2 points deducted. 4. Front passenger not wearing a seatbelt: A fine ranging from 5 to 20 yuan. 5. Using a mobile phone while driving: 2 points deducted. 6. Speeding: Depending on the vehicle, road type, and whether the speed exceeded 50% or 20% of the limit, points deducted can be 12, 6, or 3.

What's the Difference Between Plug-in Hybrid and Pure Electric?

Here are the differences between the two: 1. Pure electric vehicles only have a battery + electric motor as the sole drivetrain system, without a traditional internal combustion engine. They don't consume fuel and solely rely on electricity. In English, they're called Electric Vehicles, abbreviated as EV. 2. Plug-in hybrid vehicles can be understood as having both an electric motor and an internal combustion engine, with both capable of providing power output. The vehicle body is equipped with a charging port, allowing the onboard battery to be charged using charging stations or household electricity. Here's a detailed introduction to electric vehicles: Electric vehicles, also known as electrically driven vehicles, are divided into AC electric vehicles and DC electric vehicles. Typically, electric vehicles use batteries as their energy source, converting electrical energy into mechanical motion through components like controllers and motors, with speed controlled by adjusting current levels.

Is the Steering Wheel Movement Rotational or Translational?

The movement of the steering wheel can be either rotational or translational depending on the situation: when the car is moving straight, the steering wheel moves translationally; when the car is turning, the steering wheel rotates. The working principle of the steering wheel is to transmit torque to the rack and pinion mechanism, thereby pushing the wheels to turn left or right. Solutions for distinguishing left and right on the steering wheel include: 1. The left hand side is the left; 2. The passenger side is the right; 3. The side with gears is the right; 4. The side with the accelerator is the right. The method for removing the steering wheel is: 1. Disconnect all positive and negative battery cables; 2. Remove the lower inspection panel of the steering wheel; 3. Disconnect the connector between the airbag and the spiral cable; 4. Remove the driver's side airbag assembly; 5. Remove the steering wheel nut and take off the steering wheel.

Can You Still Drive with Blackened Engine Oil?

If the engine oil turns black shortly after use, it is a normal phenomenon. However, if it has been used for a long time, the oil needs to be replaced. Failing to replace it in time can affect the engine. Here is more information about engine oil: 1. The quality of oil is not determined by its color. The functions of engine oil include cleaning, lubrication, cooling, and rust prevention. The blackening of engine oil is caused by the combined effects of carbon deposits, gum, impurities, and other substances resulting from gasoline combustion. 2. Engine oil, also known as motor lubricant, is referred to as the 'blood' of a car. It lubricates, cleans, cools, seals, and reduces friction in the engine. 3. The quality of automotive engine oil is indicated by the letter 'S', commonly including SA, SB, SC, SD, SE, SF, SG, SH, and SJ. The alphabetical order represents the development of oil quality and the advancement of additives.
