Why does a lower gear provide greater traction?

Lower gears result in greater torque output to the drive wheels, thereby increasing traction. Here are the reasons: 1. Principle behind greater traction in lower gears: Automobile engines have two key parameters—engine power (measured in horsepower) and torque (measured in Newton-meters). Higher engine power means the engine can run faster, while greater torque translates to stronger traction and quicker acceleration. In simple terms, "power" indicates how fast the engine can rotate, whereas "torque" represents the force the engine can deliver to the wheels during friction between the tires and the ground. Power and torque cannot be maximized simultaneously; torque typically sees significant gains at low speeds, while maximum engine power generally remains constant. When climbing a slope, a vehicle requires greater torque to overcome both the friction between the tires and the ground and the gravitational force pulling the car downhill. Hence, downshifting is necessary when ascending a slope. 2. Physics formulas: (1) W=Fs=Fvt (Work = Force × Distance = Force × Velocity × Time); (2) P=W/T (Power = Work ÷ Time); Combining these two, P=Fv. When shifting to a lower gear, speed decreases, leading to an increase in traction.

Why has the idle fuel consumption of the car increased to over 50?

Here are the specific reasons: 1. A dirty or faulty engine throttle can lead to increased fuel consumption: The throttle controls the amount of air entering the engine. If the throttle valve plate is dirty, it can cause inaccurate opening of the valve plate, allowing too much air to enter the engine. More air entering the engine means more fuel injection, thus increasing fuel consumption. 2. Faulty or severely worn spark plugs can cause increased fuel consumption: Spark plugs generate an electric spark in the engine combustion chamber to ignite the air-fuel mixture. If the spark plug gap is too large, it can result in insufficient spark, leading to incomplete combustion of the mixture, which increases fuel consumption and reduces power. The same applies if the spark plug fails to ignite. 3. Excessive carbon deposits can cause incomplete combustion of the mixture, leading to increased fuel consumption: Engine carbon deposits are a coking-like substance formed from unsaturated olefins and gums in the fuel under high-temperature conditions during engine operation.

What is the fuel consumption of Mitsubishi V73?

Mitsubishi V73 fuel consumption is: Urban congested roads: Approximately 14 liters per 100 kilometers. Suburban roads: Approximately 12 liters per 100 kilometers. Highways and national roads: Approximately 9.5 liters per 100 kilometers under good and smooth road conditions. Information about car fuel consumption is as follows: Constant speed fuel consumption: It refers to the fuel economy indicator when the car is driving at a constant speed on good roads. Since constant speed driving is a basic operating condition for cars on highways, and this type of fuel consumption is easy to measure, it is widely adopted. Road cycle fuel consumption is the fuel economy indicator measured when the car is driving in repeated cycles according to specified speed and time regulations on the road, also known as multi-condition road cycle fuel consumption. In the speed and time regulations, each cycle includes various driving conditions, and specifies the shifting time, braking and parking time in each cycle, as well as the values of driving speed, acceleration, and braking deceleration.

Reasons for Abnormal Noise When Starting the X-Trail?

Reasons for abnormal noise when starting the X-Trail are as follows: 1. Hydraulic lifter issue. Due to low oil pressure or wear in the hydraulic lifter itself, air enters the hydraulic lifter, causing abnormal noise. 2. Throttle body problem. Excessive dirt in the throttle body caused by the accumulation of sludge and carbon deposits. 3. Valve clearance issue. Wear in the valve rocker arm leads to excessive valve clearance. 4. Cold start abnormal noise. If there is abnormal noise within half a minute after a cold start, which then disappears, it is usually due to the sound of the three-way catalytic converter expanding as it heats up, or wear, elongation, or loosening of the timing belt or chain. Additionally, a faulty chain tensioner losing its tensioning function can also cause abnormal noise.

Reasons for Low-Speed Jerking in the X-Trail

About the reasons for low-speed jerking in the X-Trail are introduced as follows: 1. Issues with the engine and clutch plate. It may be caused by the engine speed not synchronizing with the clutch plate speed, as the transmission's response speed is not fast enough, and the upshift speed cannot keep up with the throttle input speed, resulting in a jerking sensation during gear shifts. 2. Intervention of the energy recovery system. When the driver releases the throttle pedal or presses the brake pedal, the generator immediately starts working, imposing some load on the engine, affecting the engine speed and causing it to be out of sync with the clutch plate speed. This creates a jerking sensation. Additionally, during low-speed driving, the gear frequently shifts between first and second gears, and the clutch continuously engages and disengages, making it unable to smoothly complete power transmission in a short time, thus causing the common low-speed jerking.

What are the reasons for Audi cars burning engine oil?

Audi cars burning engine oil can be attributed to the use of inappropriate oil viscosity, the engine's negative pressure design, and engine carbon buildup. Below are detailed explanations and solutions: Use of inappropriate oil viscosity: Audi cars are high-end German vehicles, and it is best to use fully synthetic oil. The oil viscosity should preferably not be below 30, with the minimum requirement being 5W40 oil. Using oil with too low viscosity can also lead to oil burning. Engine's negative pressure design: Audi models feature a negative pressure engine design. During operation, the crankcase is in a vacuum state, causing excessive crankcase exhaust gases to enter the engine's intake system. While expelling exhaust gases, some atomized oil in the crankcase also enters the intake manifold along with the exhaust gases, resulting in significant engine oil loss. Engine carbon buildup: Due to the difference in domestic fuel quality compared to international standards, a large amount of carbon buildup can easily form in the combustion chamber during engine operation. This carbon buildup deposits in the piston grooves, causing the piston rings to stick together. As a result, the piston rings cannot seal completely, and the "stuck" piston rings greatly reduce their oil-scraping and sealing capabilities. Additionally, sludge can clog the oil return holes, preventing oil from returning normally and leading to increased oil consumption. This results in the phenomenon of Audi cars burning engine oil, necessitating the cleaning of engine carbon buildup.
