Which Direction to Loosen and Tighten Lug Nuts?

To loosen lug nuts, turn them counterclockwise; to tighten, turn clockwise. Installation Depth: When installing tire nuts, the focus is not on depth but on torque. Different specifications and grades of bolts and nuts have specified torque range values. Tighten according to the bolt's grade for normal driving conditions. Definition of Torque: Torque is a special type of moment that causes an object to rotate. Engine torque refers to the moment output from the crankshaft. At a fixed power level, it is inversely proportional to engine speed—higher speed means lower torque, and vice versa. It reflects the vehicle's load capacity within a certain range. External torque is called torsion or external couple moment, while internal torque is referred to as internal couple moment or simply torque.

What are the safety devices of a crane?

Crane safety devices: 1. Lifting limit switch, weight-type limit, rotation limit, to prevent the lifting stroke from exceeding the limit. 2. Load limiter or electronic scale, to prevent overloading of lifted objects. 3. Travel limit switch, single limit, double limit, with pre-deceleration limit, to prevent the trolley from exceeding the travel range. 4. Anti-collision device, laser detection anti-collision, distance detection through laser reflection, buffer, to absorb collision kinetic energy. 5. Electrical interlock switch, door switch, boarding request switch. 6. Overspeed switch, detects the speed of the lifting motor, activates when the motor stalls. 7. Special lifting mechanisms have speed feedback, safety brakes, safety brakes directly lock the drum.

What are the tips for using the M gear in a manual-automatic transmission?

The tips for using the M gear in a manual-automatic transmission are: 1. Step on the car's brake pedal; 2. Press the car's one-touch start button; 3. The car's instrument panel lights up, and the vehicle starts; 4. Place the car's automatic gear lever in the M gear position to enter manual mode; 5. Push the car's gear lever forward once to increase one gear; 6. Pull the car's gear lever backward once to decrease one gear; 7. Gently step on the car's accelerator, and the vehicle will start moving. A manual-automatic transmission car refers to a car equipped with a manual-automatic transmission, which combines manual shifting and automatic shifting modes. On this type of transmission, there are clear plus and minus signs, allowing manual gear shifting in this position.

What to Pay Attention to When Installing Spark Plugs?

Precautions for spark plug installation: 1. Ensure proper alignment of the threads, especially for deep spark plug holes. Use specialized tools, and if significant resistance is felt during threading, avoid applying excessive force blindly to prevent thread damage; 2. When tightening the spark plug, adhere to the specified torque to avoid under or over-tightening, which can lead to gas leaks or damage to the spark plug and its hole; 3. Securely connect the ignition wires to prevent loose connections. Commonly known as spark plugs, their function is to discharge high-voltage pulses from the ignition coil, creating an electric spark that ignites the air-fuel mixture in the cylinder. Main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface gap spark plugs.

What is the difference between small and compact SUVs?

The difference between small SUVs and compact SUVs lies in their appearance and practical usage. Details are as follows: Appearance: The most intuitive observation is that compact SUVs appear larger than small SUVs, with a very noticeable difference in actual body dimensions. Practical usage also differs significantly: Small SUVs are more suitable for young consumers as personal commuting vehicles, while they are less ideal for family use due to relatively cramped interior space. On the other hand, compact SUVs are more suitable for family use (especially after marriage), offering larger interior space that can comfortably accommodate five family members. There is also a difference in power: Small SUVs have smaller body dimensions and relatively lighter weight, so they do not require high-horsepower engines.

Why does the motorcycle taillight stay on?

Motorcycle taillight staying on may be caused by a faulty brake switch or damaged wiring. Steps to identify the specific issue: The taillight bulb of a motorcycle has two filaments - one is the running light that illuminates when the headlight is turned on, and the other is the brake light filament that activates when braking (the brake light is brighter than the running light). First determine which filament is lit: if it's the running light filament, check the headlight switch for issues; if it's the brake light filament, inspect the brake switch for problems. About brake lights: Brake lights are typically installed at the rear of vehicles with red-colored lenses to enhance light penetration. This allows following vehicles to easily detect braking actions even in low visibility conditions, helping to prevent rear-end collisions.
