Transmission slippage symptoms: When starting, pressing the accelerator pedal results in high engine RPM but slow vehicle movement; during driving, pressing the accelerator deeply leads to slow acceleration; when climbing a slope, the engine RPM is high but the vehicle moves slowly; when shifting into a certain gear while driving, the engine RPM suddenly increases but the vehicle speed rises slowly. Here are the related details: 1. The feeling of transmission slippage: Transmission slippage is accompanied by jerking. When pressing the accelerator, the engine responds quickly, and the RPM rises rapidly, but there is no sense of acceleration, giving a feeling similar to pressing the accelerator in neutral. 2. Reasons for transmission slippage: (1) Severe wear of the clutch, brake, or one-way clutch, excessive clearance of the clutch plates, leading to slippage. (2) Overfilling of transmission fluid, which generates a large amount of bubbles when vigorously stirred by planetary gears during operation, causing slippage. (3) Use of non-specified transmission fluid, as some inferior fluids can accelerate the aging, swelling, or failure of internal seals, resulting in slippage. (4) Low main oil pressure causing slippage. If the automatic transmission fluid level is too low, the filter is clogged, the oil pump is severely worn, the main oil circuit is leaking, or the main pressure regulator or pressure control solenoid valve is faulty, the main oil pressure will be too low, leading to slippage and burning of multiple actuating components.

What is the fuel consumption of the Honda Haoying?

The combined fuel consumption of the Honda Haoying is 4.9-7.3L/100km. Currently, there are 12 models of the Honda Haoying on sale. The two-wheel-drive luxury version, two-wheel-drive intelligent version, and two-wheel-drive premium version have a combined fuel consumption of 6.4L/100km. The two-wheel-drive elite version has a combined fuel consumption of 6.7L/100km. The two-wheel-drive Phantom Night version has a combined fuel consumption of 6.8L/100km. The two-wheel-drive Sharp Phantom Night version has a combined fuel consumption of 5.2L/100km. The two-wheel-drive Sharp luxury version, two-wheel-drive Sharp elite version, and two-wheel-drive Sharp premium version have a combined fuel consumption of 4.9L/100km. The manual two-wheel-drive elite version has a combined fuel consumption of 6.6L/100km. The CVT four-wheel-drive Phantom Night version and CVT four-wheel-drive premium version have a combined fuel consumption of 7.3L/100km. The above figures are NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 5.0-12.0L/100km. Reasons for high car fuel consumption: Driver's lack of skill: Improper gear shifting and excessive braking during driving will artificially increase engine power loss. Additionally, excessive braking increases the number of starts, and the fuel consumption rate is higher during starts. Engine condition is directly related to fuel consumption: If the engine has issues, fuel consumption will significantly increase. High idle speed adjustment, partial short circuit of the high-voltage coil, burnt distributor contacts, or breakdown of the capacitor will result in weak high-voltage sparks, reduced ignition capability, and incomplete combustion of some mixed gas, all of which will increase fuel consumption. Lack of maintenance during car use: Not using fuel additives regularly.

What Are the Hazards of Lugging in a Car?

The hazards of lugging in a car are as follows: 1. Severe wear on the clutch plate: Prolonged wear on the clutch plate can cause the clutch to overheat, making gear shifting difficult. 2. Severe damage to the transmission: Frequently lugging while hauling heavy loads can lead to transmission failure. 3. Severe damage to the engine: If the engine is constantly under excessive load, it will significantly shorten the lifespan of the pistons. 4. Severe wear on the rear differential: When the speed ratio of the rear differential does not match, the gears are highly prone to wear and damage. 5. Severe wear on the drive shaft: If the speed ratio is not achieved, the bearings inside the drive shaft are likely to fail.

Does the Honda Eco Mode Increase Carbon Buildup?

Honda's Eco Mode (small green leaf function) is not inherently linked to increased carbon buildup. The formation mechanism of carbon deposits is unrelated to the ECO mode, depending solely on fuel quality and operating conditions. The Honda small green leaf function, also known as ECO mode, works by adjusting various parameters such as transmission gear position, engine speed, braking system, and transmission oil temperature through multiple sensors. The ECU then calculates the optimal fuel injection quantity to achieve fuel efficiency. When ECO mode is activated, the vehicle's computer reduces fuel injection, lowers engine speed as much as possible, and makes the engine response slower to save fuel. In traffic jams and during low-speed urban driving, ECO mode provides smoother power output and more noticeable fuel-saving effects. Conversely, during high-speed driving, ECO mode requires deeper throttle input, which may actually increase fuel consumption. Engine carbon buildup primarily occurs for two reasons: poor fuel quality and incomplete combustion. Poor fuel quality refers to the presence of excessive gum substances in the fuel, which leave residues during combustion that accumulate over time to form carbon deposits. When the engine operates at low speeds, incomplete combustion occurs, leading to residue accumulation inside the engine and the formation of carbon deposits. Typically, drivers can burn off some carbon deposits by driving at high speeds. For thorough removal, it is necessary to visit a maintenance facility for cleaning.

What Should You Know About Being a Car Salesperson?

To be a car salesperson, you should know how to combine the car products you are selling with an understanding of the competition. Below is a relevant introduction regarding considerations when buying a car: 1. Determine your budget: When buying a car, first determine your budget range and reasonably estimate your financial capability. Avoid blindly choosing high-priced cars that exceed your financial capacity. The cost of the car, plus insurance and routine maintenance, can be a significant expense. Act within your means to prevent the car from becoming a burden. If you are not in a hurry to buy, it's best to choose a time when car prices are lower and market prices are stable, typically during the off-season from March to August. 2. Inspection upon delivery: When picking up the car, pay attention to the body gaps and paintwork. Check the door gaps and the gaps on the front and rear bumpers. Open the doors to observe if there is any color difference between the interior and exterior paint. Inside the car, check the odometer reading, whether the seat protective packaging and the plastic sheets on the dashboard are intact, and if there are any stains on the seats or dashboard. Also, note if there is a significant gap between the manufacturing date and the delivery date. If the gap is too long, the car might be a display model or a refurbished vehicle (test drive car). Start the car to feel its operating condition, such as any unusual noises or if any warning lights are on.

How Long Can a Car Be Driven Continuously?

Continuous driving of a car should not exceed four hours. According to Article 62 of the 'Regulations for the Implementation of the Road Traffic Safety Law': If driving a motor vehicle continuously for more than 4 hours, the driver must stop to rest, with a rest period of no less than 20 minutes. According to the 'New Traffic Regulations on Driver's License Deduction Rules': Driving a medium-sized or larger passenger vehicle or a hazardous materials transport vehicle continuously for more than 4 hours without stopping to rest or with a rest period of less than 20 minutes will result in a 12-point deduction. Driving any other motor vehicle continuously for more than 4 hours without stopping to rest or with a rest period of less than 20 minutes will result in a 6-point deduction. The main causes of driving fatigue are as follows: Sleep quality: Going to bed too late, insufficient sleep time; poor sleep quality; noisy sleep environment that affects sleep quality; Vehicle environment: Poor air quality, inadequate ventilation; excessively high or low temperatures; severe noise and vibration; improperly adjusted seats; Driving experience: Low skill level, unfamiliarity with operations; short driving time, lack of experience; poor safety awareness. Hazards of fatigue driving: Driving fatigue affects the driver's attention, sensation, perception, thinking, judgment, willpower, decision-making, and movement. When fatigued, drivers may experience blurred vision, soreness in the back and waist, stiff movements, weakness in limbs, slow reactions, lack of concentration, reduced judgment, increased operational errors, and even unsafe factors such as mental haziness or momentary memory loss. If the driver continues to drive under these conditions, it can easily lead to traffic accidents.

What is the aoff button?

This is the off button for the auto start-stop system, where 'off' means to turn off. Cars equipped with the auto start-stop function have an off button, and pressing it can deactivate the auto start-stop. The off button for the auto start-stop is a circle with an 'A' inside and 'off' below the circle, indicating the deactivation of the auto start-stop. Cars with the auto start-stop function will shut off the engine when stopped at a red light, provided the battery has sufficient charge and the engine coolant has reached normal operating temperature. If the battery charge is insufficient, the auto start-stop system will not function, and the system's indicator light on the dashboard will flash yellow. If the system is operational, the indicator will flash green. When the aoff light is on, it means the vehicle's engine auto start-stop function is active. This function effectively protects the engine from damage, reduces fuel consumption, and is very practical. The aoff button is primarily used when the car is moving at low speeds or repeatedly stopping, helping to automatically shut off the engine, reduce idle time, and consequently minimize engine carbon buildup. For the auto start-stop function to work, certain conditions must be met: the engine coolant temperature must reach at least 85 degrees Celsius, and the engine oil must also reach operating temperature. After the car starts, the auto start-stop function enters the active mode. For example, when approaching a traffic light, stopping and pressing the brake for 1 to 2 seconds will automatically shut off the engine. To restart when the light turns green, lightly press the accelerator or turn the steering wheel, and the engine will start again. In some manual transmission cars, the computer determines the need to shut off the engine based on actions like pressing the clutch, shifting to neutral, and pulling the handbrake. The engine will restart when the clutch is pressed again. However, in congested traffic when moving slowly, reversing into a parking space, or on steep slopes, you may choose to turn off this function. When driving through water, always remember to turn off this function to prevent water from entering the exhaust pipe and then the engine, which could prevent the engine from starting. Precautions for auto start-stop: Avoid using the start-stop system on slopes; Turn off the system during irregular stop-and-go traffic; Do not activate the system when the air conditioning is on; Disable the system during low-speed parking; Do not refuel when the start-stop system has shut off the engine; It is advisable to turn off the system when the fuel light is on; Always deactivate the system when driving through water.
