The difference between 1.4 and 2.0 lies in their displacement, as well as the power output and fuel consumption they exhibit. Below is an introduction to displacement-related information: 1. Displacement: Displacement is the total working volume of all cylinders in an engine, calculated by multiplying the volume swept by the piston from top dead center to bottom dead center by the number of cylinders. Displacement is a crucial structural parameter that comprehensively measures the size of an engine. The performance indicators of an engine are closely related to its displacement. Generally, the larger the displacement of a car, the higher its power output. Unit displacement is commonly used as a basis for evaluating the size of different engines. 2. According to the standards in Mainland China, cars are classified as follows: micro cars (displacement below 1L), compact cars (displacement between 1.0~1.6L), mid-size to full-size cars (displacement between 2.5~4.0L), and luxury cars (displacement above 4L).

I've driven a 1.4L displacement car, which felt great in the city—fuel-efficient and agile, with fuel consumption just over 5 liters in traffic jams, saving hundreds on monthly fuel costs. However, the downside was struggling on hot days when climbing hills or overtaking on highways, with the engine buzzing loudly but lacking power. After switching to a 2.0L, the power was noticeably stronger, with quicker starts and steadier performance at high speeds, though fuel consumption rose to around 8 liters, significantly increasing fuel expenses. The differences aren't just in power and fuel consumption; larger displacement cars are often heavier and quieter, better suited for long trips or those who enjoy a more robust driving experience. Smaller displacement cars are lighter and more economical, but you need to be careful not to overload them for extended periods to avoid engine damage. Overall, it depends on your usage, driving habits, and budget.

How to Open the Fuel Tank Cap on an Audi?

Audi's method for opening the fuel tank cap: Unlock the central locking system, then exit the vehicle and press the fuel tank cap. In the hydraulic system, the fuel tank not only stores fuel but also serves to dissipate heat, separate air bubbles from the oil, and settle impurities. Try to avoid waiting until the fuel warning light comes on before refueling, as doing so frequently can shorten the fuel pump's lifespan. Taking the Audi A6 as an example, its dimensions are 5012mm in length, 1855mm in width, and 1485mm in height, with a wheelbase of 2945mm. The vehicle is equipped with features such as a leather-wrapped steering wheel and seats, seat heating, wood trim accents, an electric rear window sunshade, BOSE audio system, memory function for front power seats and mirrors, front and rear parking sensors, and cruise control.

What is the correct method for starting an automatic transmission car on a slope?

Correct method for starting an automatic transmission car on a slope: 1. When starting on an uphill section with an automatic transmission, first firmly pull the handbrake, then start the car by pressing the brake pedal with your right foot; 2. Shift the gear to position 1 or 2, release the brake, place your right foot on the accelerator pedal to add throttle while simultaneously releasing the handbrake with your right hand; 3. When going downhill, also use a low gear, either 1 or 2, do not press the accelerator pedal, let the car descend by inertia, but keep your right foot on the brake pedal to control the speed. The difference between automatic and manual transmissions lies in the clutch and gearbox. When starting on a slope, an automatic transmission is more challenging, as it's not easy to shift into D gear when starting, or after barely shifting into D gear, you might hear a clunk sound, and the car may vibrate slightly.

What Causes Severe Shaking When Shifting to R Gear in an Automatic Transmission?

The reasons for severe shaking when shifting to R gear in an automatic transmission are: 1. Low idle speed; 2. Dirty throttle body; 3. Dirty fuel injectors; 4. Severe engine carbon buildup; 5. Poor spark plug performance. It is normal for automatic transmission vehicles to experience slight shaking when shifting gears, as the clutch differential is engaged and the engine generates torque. However, it is important to note that the vehicle must be completely stopped before shifting gears. When reversing, the direction of power transmission needs to change. Shifting gears without stopping the vehicle can cause noise in the transmission and may even severely damage it. An automatic transmission eliminates the need for the driver to manually shift gears, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Typically, automatic transmission vehicles have six gear positions, arranged from top to bottom as: P, R, N, D, S, L.

What is the shutdown sequence for automatic transmission vehicles?

Automatic transmission vehicle shutdown sequence: 1. When driving in D gear, apply the brake to slow down until coming to a complete stop; 2. After stopping, shift the gear to P; 3. Engage the parking brake, release the foot brake and turn off the engine. For stopping at a red light: 1. When driving in D gear, apply the brake to slow down until coming to a complete stop; 2. After stopping, shift the gear to N; 3. Engage the parking brake and release the foot brake; 4. When the light turns green, press the brake, shift to D gear and start moving. Automatic transmission means the driver doesn't need to manually shift gears, as the vehicle will automatically select the appropriate gear based on driving speed and traffic conditions. There are six gear positions on the vehicle, from top to bottom: P, R, N, D, S, L.

What to do if the automatic transmission is stuck in P gear?

Solutions for automatic transmission stuck in P gear: 1. If the car has a shift lock gear lock, press the switch; 2. If there is no gear lock or the button does not work, you can pry open the shift dust cover, find the emergency switch of the shift mechanism, and press the switch. The correct method for parking and shifting gears: 1. Shift into N gear before parking; 2. Tighten the handbrake and then release the pedal; 3. After the car stops completely, shift into P gear. This way, the car will not slide forward or backward due to its own weight, avoiding the situation of the gear getting stuck when parking. Automatic transmission means that the driver does not need to manually shift gears. The vehicle will automatically select the appropriate gear to drive based on the speed and traffic conditions.
