What are the specifications of various models of pulleys?

Pulley models are divided into the following 6 categories: flat surface plain bearing pulleys; concave surface plain bearing pulleys; flat surface ball bearing pulleys; concave surface ball bearing pulleys; flat surface needle bearing pulleys; concave surface needle bearing pulleys. Each category is further divided into 02, 04, 06, 08, 10, and 13 specifications based on load capacity. Characteristics of pulley shapes: Small-sized pulleys with relatively low load-bearing capacity are solid pulleys, made of 15 steel, Q235, or cast iron. Pulleys bearing heavy loads are made of ductile iron or cast steel, cast into structures with ribs and holes or spokes. Pulleys are categorized into "fixed pulleys" and "movable pulleys": Fixed pulley: The position of the axle remains stationary during use; essentially an equal-arm lever that can change the direction of the applied force. Movable pulley: The position of the axle moves along with the object being pulled; saves half the force but doubles the distance.

When to Turn On ECO Mode?

It should be turned on in most cases. However, there are two situations where it is not recommended: When the vehicle speed is very high (reaching 100KM/h): During high-speed driving, the vehicle requires better power performance. At this time, the acceleration effect of ECO mode is not ideal, requiring deeper throttle input, which actually results in insignificant fuel-saving effects. Moreover, even if ECO is activated, the vehicle's computer will prioritize speed, causing the ECO mode to automatically deactivate. When high torque output is needed (e.g., climbing a slope): When high torque output is required, such as when climbing a slope, the engine computer will prioritize ensuring sufficient power to drive the vehicle, and the ECO mode will not function either. Modern cars generally offer three driving modes to choose from: Eco mode, Comfort mode, and Sport mode. Below is information about these three modes: Eco mode: When the car is in this mode, fuel consumption is relatively low. The throttle pedal sensitivity decreases, and the transmission shifts up more aggressively. Comfort mode: This mode can be considered a normal operating mode for the car. In this mode, the throttle pedal response is more sensitive than in Eco mode. Sport mode: This mode can be used during aggressive driving. After activating Sport mode, the throttle pedal response becomes very sensitive, and the transmission delays shifting. The transmission will only upshift when the engine speed reaches the redline zone. After switching to Sport mode, the engine speed will remain around 3,000 RPM, ensuring better power response during acceleration. When the car enters ECON mode, it can achieve reduced fuel consumption and energy savings, but the vehicle's power will weaken. ECON can be understood as an abbreviation for "economy." In most cases, it is recommended to activate ECON mode, except when high torque output is needed (e.g., climbing a slope) or when the vehicle speed is very high, in which case ECON mode must be turned off. After pressing the ECON button, the car enters a low-carbon, eco-friendly driving mode. Subsequently, the ECU, engine, and transmission intelligently execute the driver's intentions in the most fuel-efficient manner, achieving optimal fuel economy through rapid upshifts and smooth acceleration. The air conditioning also operates in an energy-saving state. When the driver presses the throttle pedal deeply, the ECON system effectively controls the opening and closing of the intake valves to ensure smooth engine operation and energy savings.

Is it okay to reverse at a highway toll gate if the ETC doesn't work?

Reversing at a highway toll gate when the ETC doesn't work is not considered a traffic violation. The toll station is not considered part of the highway, so reversing is allowed. However, when reversing, you need to ensure the surroundings are safe. If it is safe, you can reverse out of the ETC lane and re-enter the manual toll lane to queue. ETC Usage Precautions: The ETC transaction sensing range is 8 meters. If the vehicle in front is stopped, to prevent issues such as the front vehicle's ETC device malfunctioning or not having an ETC device at all, maintain a distance of at least 10 meters to avoid automatic payment for the front vehicle. The ETC lane recognition speed is 20 km/h. Driving too fast may result in failure to read the vehicle's device information, leading to payment failure. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag becomes loose or detached, may cause the tag to deactivate. In such cases, you can take it to the bank where the ETC card was issued or a highway service center for inspection. If the issue is not due to human interference, reactivation may suffice. When using a debit card linked to ETC, insufficient balance may cause payment failure. Follow the instructions of on-site staff to use the manual MTC lane and pay via cash or card. Thick car windshields may cause poor signal reception. This is especially important for vehicles that have had their windshields replaced after accidents or modified front windshields.

Can Pine Resin Dropped from Pine Trees on Cars Be Washed Off?

Pine resin dropped from pine trees on cars can be washed off. Basic Information about Pine Resin: Pine resin is a pale yellow or dark brown liquid with a distinctive odor of pine root oil. It has strong emulsifying properties, good wetting, penetrating, and leveling abilities, making it suitable for washing, fabric dyeing, and as a solvent for coatings, varnishes, and oils. It is also used as a mineral flotation agent, alcohol denaturant, antifoaming agent, and wetting agent. Storage Methods for Pine Resin: Store in containers made of iron, mild steel, copper, or aluminum. For long-term storage, keep in a cool, ventilated place away from light and sealed to avoid exposure to air and light, which can lead to the formation of resinous substances. Avoid skin contact.

What is the general standard for four-wheel tire pressure?

The general standard for four-wheel tire pressure is 2.5kg for the front wheels and 2.7kg for the rear wheels. In summer, it is 2.3kg for the front wheels and 2.5kg for the rear wheels. Before traveling, observe the tire condition: Radial tires—commonly known as low-pressure tires—are normal as long as the flatness is not too low. If you feel strong elasticity when stepping on them with your foot and they are not too soft, they are normal. High-pressure tires—bias-ply tires with inner tubes—are normal if the shoulder area does not protrude when viewed from the front (commonly referred to as 'not bulging') and the contact area with the ground appears similar to usual when viewed from the side. Pay attention to the sound of tire friction with the ground: While driving, listen to the sound of tire friction with the ground, feel the cushioning force when passing over uneven roads, and notice if there are any changes in acceleration when accelerating compared to usual. These are all experiences accumulated over time.

Can the wiper handle be replaced if it breaks?

The wiper handle can be replaced if it breaks. You can purchase the corresponding parts and replace it yourself, or you can go to a 4S shop for replacement. Replacement method: Use the controls in the car to lift the wiper upright, locate the position of the buckle on the wiper, release the buckle to remove the wiper; After removing the wiper, install the new wiper in the reverse order; When installing the new wiper, pay attention to the different lengths of the wipers. The longer one is generally in front of the driver's seat, and the shorter one is in front of the passenger seat. Be careful not to install them incorrectly. Daily maintenance methods for wipers: Regularly use cleaning agents to remove stains on the wipers and clean residual grease on the windshield to prevent friction noise during operation; Replace the wiper when necessary to prevent aging due to weather conditions, which may cause the wiper to malfunction.
