It refers to the average speed of a vehicle traveling on a specific road section. Calculation method of speed: It is the quotient obtained by dividing the length of the road section by the pure travel time of the vehicle (travel time after deducting all stopping times). It is used to analyze the ease of travel and traffic capacity of that road section. Differences between travel speed and trip speed: They differ in nature; their distribution measured values are different; their calculation formulas are different. Travel speed is the average speed of a vehicle traveling on a specific road section. Speed distribution is a numerical value that reflects the dispersion characteristics of speed. Drivers travel according to their personal will on the road but are constrained by other vehicles, road conditions, etc., making it impossible to have a uniform speed. To ensure the accuracy of test data, travel speed usually requires the test vehicle to travel 12 to 16 times on that road section, and the speed value is obtained through statistics. When organizing and analyzing the measured values of speed distribution for trip speed, the sequence is: speed sorting and grouping, which are summarized into 8 to 12 groups. Travel speed is the quotient obtained by dividing the length of the road section by the pure travel time of the vehicle (travel time after deducting all stopping times), used to analyze the ease of travel and traffic capacity of that road section, whereas trip speed is not.

What are the symptoms of a dirty fuel injector?

Symptoms of a dirty fuel injector include: 1. Increased engine noise; 2. Unresponsive throttle; 3. Poor acceleration; 4. Minor idling vibrations. The fuel injector is located on the intake manifold or direct-injection cylinder block. Its working principle is: when the electromagnetic coil is energized, it generates suction, lifting the needle valve to open the injection hole. Fuel is sprayed at high speed through the annular gap between the needle valve head and the injection hole, forming a mist for optimal combustion. The cleaning method for a car fuel injector is: 1. Hang the cleaning device on the car's front hood; 2. Locate the engine's fuel supply and return lines; 3. Disconnect the return line from the engine, select the appropriate adapter, and plug the return line; 4. Connect the supply line to the cleaning device's outlet line; 5. Open the fuel tank cap, remove the fuel pump fuse to stop the fuel pump, and the cleaning process is complete.

Is Car Soundproofing Necessary?

Car soundproofing is not necessary, and improper soundproofing modifications can lead to many adverse consequences. Car soundproofing materials include: soundproofing strips, foam filling, damping glue, soundproofing cotton, engine soundproofing pads, and low-frequency mesh. The full-vehicle soundproofing locations include: the chassis, four doors, trunk, tailgate, hood, fenders, roof, dashboard, firewall, and U-shaped groove. The method for full-vehicle soundproofing is as follows: 1. Drive the car to a safe location, engage the handbrake, and turn off the engine to ensure safety. Remove the interior trim in the order of exterior to interior, exposing the working surface while placing the removed screws and clips into a sealed plastic bag. 2. Thoroughly clean the working surface with a tar remover. For difficult-to-remove attachments, try using other specialized solvents to dissolve them first, then slowly scrape them off with a specialized scraper. 3. Reinstall the interior trim from the inside out as it was originally. During installation, all components must be reinstalled exactly as they were, and all screws and clips must be tightened and secured to avoid generating secondary noise.

What Gauge Wire is Needed for Portable New Energy Vehicle Charging?

New energy portable vehicle charging requires 4-gauge or 6-gauge wires. New energy vehicle charging requirements: Charge correctly to avoid over-discharging or excessive power usage; inspect the wiring condition of the charging cable before each charge to prevent safety incidents; during charging, the battery's temperature will increase, and the charger will also generate significant heat, so charging should be done in a well-ventilated environment. New energy vehicle charging methods: Portable charging: Use the portable charging cable included with the vehicle to charge via a standard household socket. Home charging: Private users can purchase home charging stations that often come as a gift with electric vehicles.

What does the little person on the steering wheel mean?

The little person on the steering wheel indicates that the airbag warning light is on, which means the airbag system has self-diagnosed a fault in one part of the airbag mechanism. Possible causes of airbag system failure: Failure of the collision sensor; Malfunction of the electronic control unit (ECU) for the airbag; Fault in the corresponding wiring; Failure of the airbag warning light. Precautions during inspection: Do not impact the sensor or airbag; Airbags can only be used once and must be replaced along with the entire assembly; If a collision has occurred and the airbag has been triggered, the collision sensor cannot be reused; When removing the steering wheel airbag assembly, ensure the cushion surface faces upward and is not inverted; Do not use a multimeter to directly measure the resistance of the airbag's detonator; When removing the front passenger airbag assembly, place the airbag door facing upward.

Where is the Tire Pressure Reset Button?

The tire pressure reset button is located on the control lever to the left of the steering wheel. The method for resetting tire pressure is: press the SET button, select reset, wait for the prompt indicating that tire pressure learning has begun, and then use a reset tool to complete the reset. The tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. It transmits the pressure information from inside the tire to a central receiver module via a wireless transmitter, then displays the data for each tire's pressure. When the tire pressure is too low or there is a leak, the system will automatically issue an alert. After the tire pressure monitoring system alerts, the tire pressure should be checked and adjusted as soon as possible. Only after confirming that the tire pressure is normal should you continue driving. The tire pressure monitoring system will automatically reset after the vehicle has been driven for a certain distance.
