What does the little mouse in the car mean?

The little mouse in the car refers to the fuel-consuming configurations in the vehicle. This 'little mouse' that 'steals' fuel is the engine start-stop technology. Below is a related introduction to the car's little mouse: 1. Engine start-stop technology: Engine start-stop technology automatically shuts off the engine when the vehicle comes to a temporary stop during driving (e.g., waiting at a red light). When it's time to move forward again, the system automatically restarts the engine. 2. How the start-stop system works: When the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates there is enough energy for the next start. Once these three conditions are met, the engine automatically stops running.

What Does Car Torque Mean and What Is Its Function?

Car torque is a type of data output from the crankshaft end, where the faster the rotational speed, the smaller the torque provided. Function: This data reflects the car's ability to generate load within a corresponding range. In essence, it serves a similar purpose to power, acting as a parameter that reflects the car's performance. It demonstrates the car's speed, climbing ability, and the capability of its suspension system. Below is a related introduction to car torque: 1. Calculation Method: The theoretical formula provided by professionals is: Driving Force = Torque × Transmission Gear Ratio × Final Gear Ratio × Mechanical Efficiency. When the piston performs reciprocating work inside the cylinder, the work done per unit is commonly referred to as torque. 2. How to Choose Car Torque: Engine torque refers to the moment output from the crankshaft end of the engine. Under fixed power conditions, it has an inverse relationship with engine speed—the faster the speed, the smaller the torque, and vice versa. This reflects the car's load capacity within a certain range.

Differences Between OEM and Aftermarket Three-Way Catalytic Converters?

As automotive components, the quality differences between OEM and aftermarket three-way catalytic converters are as follows: 1. Exhaust Gas Purification Performance: It is advisable to use OEM converters for exhaust purification to prevent emission test failures during annual inspections. Many aftermarket converters lack effective conversion capabilities. 2. Manufacturing Sources: OEM three-way catalytic converters are produced by authorized manufacturers with relevant certifications and receive automaker approval. Aftermarket converters typically come from three types of manufacturers: small workshops (often producing unusable products), standard aftermarket producers (the choice for most car owners), and high-imitation manufacturers (only lacking automaker certification compared to OEM). 3. Price and Quality Comparison: OEM three-way catalytic converters generally exhibit no significant issues in appearance or performance, though they come at higher prices. Aftermarket converters are produced by various brands with varying price points and inconsistent quality standards.

What's the matter when the child lock cannot open the door from both inside and outside?

Child locks are almost standard equipment in every car. Generally, cars have child locks on the two rear doors. When the child lock is activated, the door cannot be opened from the inside, only from the outside. If the door cannot be opened from the outside either, it may indicate a malfunction with the door lock. In this case, it is best to go to a 4S shop for inspection and repair. Below are some related precautions regarding car child locks: 1. Equip a safety seat: If children are placed in the rear seats, not only should they be provided with a safety seat, but the child safety lock should also be engaged. 2. Check the central locking system: Always ensure that the central locking system is in the locked state while driving to prevent children from accidentally opening the door. 3. Adults should open the door for children: When getting out of the car, it is best for an adult to personally open the door for the child to avoid any unnecessary safety accidents with vehicles in front or behind during the exit process.
