What are the differences between automatic transmission and manual transmission?

Automatic transmission and manual transmission differ in terms of price, gearbox, and driving operation. The specific differences are as follows: 1. Different car prices: For vehicles with the same model configuration, the price of automatic transmission models is higher than that of manual transmission models. 2. Different gearboxes: Automatic transmission cars use an automatic gearbox, while manual transmission cars use a manual gearbox. 3. Different driving methods: When driving an automatic transmission car, you only need to switch to the desired gear, such as shifting to drive mode without the need for manual gear shifting, as the gearbox shifts automatically. In contrast, manual transmission cars require manual gear shifting based on speed and RPM to switch to the appropriate gear. 4. Different clutch pedals: Automatic transmission gearboxes do not have a clutch pedal, while manual transmission cars have a clutch pedal. 5. Different gear markings: The gear markings for automatic transmission gearboxes are P, R, N, D, etc., while the gear markings for manual transmission gearboxes are 1, 2, 3, 4, 5, 6, R, etc.

What are the symptoms of vehicle oil leakage?

Vehicle oil leakage symptoms include oil stains on the engine surface, and in severe cases, oil spots on the ground where the vehicle is parked. Causes of vehicle oil leakage: 1. Car engine oil leakage: There are clearly visible oil stains on the surface of the car engine casing. If these stains are cleaned off and reappear shortly after, or even in severe cases where oil drips like water droplets, the car should be sent for repair as soon as possible. 2. Car engine oil seepage: If there are only minor oil stains on the engine casing, this indicates that the oil leakage is not particularly severe. The amount of seepage is minimal and hardly affects the engine. The most direct and effective solution is to replace all the sealing rings. In congested urban traffic, frequent stopping and starting requires constant gear shifting. Modern cars have increasingly more gears, leading to even more frequent gear shifts, greater working pressure inside the transmission, higher temperatures, and accelerated aging and deformation of the rubber seals in the transmission.

What is the fuel consumption of the Land Rover Evoque per 100 kilometers?

The comprehensive fuel consumption of the Land Rover Evoque is 7.3L/100km. There are currently 5 models of the Land Rover Evoque available for sale: the Elite Edition, Dynamic Edition, First Edition, R-Dynamic SE, and R-Dynamic HSE, all with a comprehensive fuel consumption of 7.3L/100km. The above figures are based on the NEDC comprehensive fuel consumption, which is measured under the NEDC test procedure for combined driving conditions. The actual fuel consumption is higher than this value, ranging from 7.6-15.0L/100km. Automobile fuel consumption is directly related to five major factors: driving habits, the vehicle itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before red lights will increase fuel consumption. The vehicle itself: Cars with larger engine displacements consume more fuel than those with smaller displacements because larger displacements generally mean greater power output, requiring more gasoline for combustion. Heavier vehicles also have higher fuel consumption due to the greater driving torque needed. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases vehicle resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily during cold starts, requiring more gasoline for combustion, which increases fuel consumption. Additionally, in low temperatures, the engine control unit will operate at higher RPMs to warm up the engine, further increasing fuel consumption.

What does the E and F on the fuel tank represent?

E and F represent the volume of the car's fuel tank. On the fuel gauge of the car's dashboard, the characters E and F are used. F stands for full, and E stands for empty. If the fuel gauge needle is at the F position, it means the car's fuel tank is full. If the fuel gauge needle is at the E position, it means the fuel tank is almost empty. When the car is low on fuel, a warning light will illuminate on the dashboard. The fuel warning light is usually shaped like a fuel tank. When fuel is low, the warning light will turn yellow; in cases of extremely low fuel, the warning light will turn red. Some car models only display a yellow fuel warning light, in which case the owner should pay attention to the remaining fuel level and refuel in time. During the refueling process, it is not advisable to fill the car's fuel tank to the brim, especially in hot summer weather. This is because gasoline expands and evaporates into vapor under high temperatures, and the resulting vapor or even liquid can enter the carbon canister for storage. Overfilling the tank can cause deviations in the fuel gauge needle. Even after prolonged use, the fuel gauge needle may not drop and will only return to normal after some time. Effects of low fuel levels: Fuel sloshing causing the car to stall: When the fuel level is too low, on bumpy or winding roads, the fuel can slosh around, and the fuel pump may not be able to pump fuel in time. This can lead to insufficient fuel supply, causing the car to experience jerking, hesitation, or stalling. Fuel pump overheating: The fuel pump is cooled by the fuel. If the fuel level is too low, the cooling performance of the fuel pump decreases, accelerating wear on internal components and potentially leading to short circuits or burnout. Clogging the fuel system: The bottom of the fuel tank contains more impurities. If the fuel level is too low, these impurities can enter the fuel supply system due to fuel sloshing, leading to clogged fuel lines. Affecting driving safety: Low fuel levels can easily cause the car to stall. If the car stalls while driving, both steering and braking can be affected. If there is heavy traffic on the road, this can lead to traffic accidents.

What is the difference between 75w80 and 75w90?

Generally, cars use 75W-90 which is suitable for all seasons. More accurately, you should follow the specifications in your vehicle's manual. 75W indicates low-temperature performance with a minimum operating temperature of -42°C, while 90 represents the viscosity at high temperatures. 75W-80 has relatively lower viscosity. Typically, the lubricating oil used for transmissions and rear axle gear transmission mechanisms is called gear oil. The contact stress and relative sliding speed on the tooth surface engagement part vary greatly depending on the mutual position of the gear axes and the tooth profile, thus requiring different types and varieties of gear oil. Viscosity grades of gear oil: 1. Classification: According to the kinematic viscosity at 100°C and the maximum operating temperature when the apparent viscosity is 150,000 mPa.s, it is divided into seven viscosity grades (brands): 75W, 75W/90, 80W/90, 85W/90, 90, 85W/140, and 140. 2. Ordinary vehicle gear oil: Suitable for manual transmissions and spiral bevel gear drive axles under moderate load and speed with relatively harsh conditions. Divided into three specifications based on viscosity: 80W/90, 85W/90, and 90. The 90-grade oil can be used year-round in areas south of the Yangtze River. 3. Medium-duty vehicle gear oil: Suitable for gears operating under low-speed high-torque and high-speed low-torque conditions, as well as drive axles with hypoid gears under less harsh conditions. Divided into five specifications based on viscosity: 75W, 80W/90, 85W/90, 90, and 85W/40, among which the 90-grade oil can be used year-round in areas south of the Yangtze River.
