Below is a detailed introduction to the differences between small, medium, and large ratchet wrenches: Differences in wrench size: 3/8 refers to the side length of the square interface on the socket wrench, which is 3/8 inches in length. 1/4 small ratchet wrench has a square drive size of 6.3MM. 3/8 medium ratchet wrench has a square drive size of 9.5MM. 1/2 large ratchet wrench has a square drive size of 12.5MM and provides greater torque. Differences in nut size they can handle: Small ratchet wrenches are particularly suitable for tightening or loosening nuts with sockets under 14MM. Medium ratchet wrenches are suitable for use with sockets up to 24MM. Large ratchet wrenches are suitable for working with sockets up to 32MM.

What are the causes of high fuel injection temperature?

Here are the reasons for high fuel injection temperature: Air leakage in the fuel supply system: This fault often occurs after maintenance. Mainly due to unsealed fuel line joints, fuel filter sealing rings, etc., which cause the fuel system to suck in a lot of air, resulting in insufficient fuel supply. At this time, the air leakage points should be checked one by one and resolved. Insufficient fuel supply pressure from the fuel pump: Fuel pump piston leakage and poor sealing of the fuel pump inlet and outlet valves are the main factors affecting fuel supply pressure. This results in insufficient fuel injection, which affects the fuel injection temperature. Insufficient fuel injection volume from the fuel injection pump: In addition to the above factors affecting fuel injection volume, insufficient calibrated fuel injection volume from the fuel injection pump itself is also a main cause of high fuel injection temperature. For example, severe wear of the plunger is also a main reason for the decrease in fuel injection volume. At this time, the pump should be calibrated on the test bench.

Why Does the Engine Sound Louder After Water Intake?

Here are the reasons why the engine sounds louder after water intake: Not Started: The vehicle was submerged in water causing the engine to take in water, and more critically, the engine was not started until the vehicle was towed to the repair shop, leading to a louder engine sound due to water intake. Restarted: The vehicle was driven in water, causing the engine to stall due to water intake. Upon restarting, the engine sound became louder. Engine Started: After the engine took in water (a small amount that does not prevent the engine from starting), the owner unknowingly started the engine and drove for some distance, resulting in a louder engine sound.

How Often Should the Battery in a Smart Car Key Be Replaced?

Generally, a new car key can last for two to three years when fully charged. Signs that the car key battery is running low: Reduced effective range: Previously, the car door could be unlocked within a distance of 6 meters, but when the key battery is low, you need to get closer to the car, even right next to the door, for it to respond. This indicates that the car key battery is almost depleted. Occasional remote failure: When using the remote to unlock the car door, it sometimes works and sometimes doesn't. You might need to press the button multiple times for a response, which means the car key battery is nearly dead. Dim indicator light: Observe the indicator light on the key. When you press the button, the light may appear dimmer than usual or flicker intermittently. This is a sign that the battery needs to be replaced.
