What does the car s driving performance on soft ground belong to?

The six major properties of the car are BAI power, fuel economy, braking, handling stability, smoothness and passability. The ability of a car to work at maximum efficiency under certain conditions is called car performance. It is a characterization of the structural characteristics that determine the efficiency and convenience of automobile utilization.

The fuel economy of a car is usually measured by the fuel consumption of a car traveling 100 kilometers under certain working conditions or the mileage that a certain amount of fuel can make a car travel. In China and Europe, the unit of automobile fuel economy index is l 100km, that is, the number of liters of fuel consumed by the car for 100km, the smaller the value, the better the fuel economy of the car, and the more fuel-efficient the car.

In the United States, it is expressed as mpg or mi gall, that is, the number of miles per gallon of fuel, which means the number of miles per gallon of fuel, the higher the value, the better the economy of the car, and the more fuel-efficient the car. Fuel economy is related to many factors, such as driving speed, with fuel consumption being lowest when the car is driving at moderate speeds close to low speeds, and increasing rapidly at high speeds as the speed increases. In addition, the maintenance and adjustment of the car will also affect the fuel consumption of the car.

Extended information: The six major properties of a car - passability refers to the ability of a vehicle to pass through certain road conditions. With a strong car, you can easily climb over the slope with a large slope, you can safely drive into the river at a certain depth, or you can drive at high speed on the rugged mountain road, and you don't have to worry about stopping and getting on and off the road in the city.

In short, it can make you more likely than other vehicles to go where you want to go and experience the feeling of conquering nature.

Power, safety, energy consumption performance, and stable performance.

Maximum power, horsepower, maximum torque, hehe.

A car is a vehicle that uses gasoline, diesel or natural gas as an energy source and is powered by an engine. Vehicles that generally have four or more wheels and are able to travel on land without relying on tracks or wires.

Look at the engine of the car.

The climbing ability of the car is projected by the off-road performance, grip performance, power performance, driving force distribution performance, weight distribution rationality, etc.

Hello, the climbing ability of the car reflects the dynamic performance of the car.

The performance indicators commonly used to evaluate the performance of the car mainly include: power, fuel economy, braking, handling stability, smoothness and passability. The ability of a car to work at maximum efficiency under certain conditions of use is called car performance.

It is a characterization of the structural characteristics that determine the efficiency and convenience of automobile utilization.

The dynamics of a car are expressed in terms of the average speed that a car can achieve when driving in a straight line on a good road surface. The dynamics of the car are mainly evaluated by three indicators: the maximum speed; the acceleration time of the car; The maximum incline that a car can climb.

The maximum climbing degree of the car refers to the maximum slope that the car can overcome with the first gear on a good road surface when the car is fully loaded, which characterizes the climbing ability of the car. The gradeability is expressed as the angular value of the slope (expressed in degrees) or as a percentage of the height difference between the start and end points of the slope and its horizontal distance (tangent).

Car gradeability expresses the car's ability to climb hills. The car can climb uphill only if the car traction is greater than the uphill resistance and rolling resistance (air resistance is not counted). The measurement method of expressing the climbing ability of this car is the percentage slope, which is expressed by the ratio of the height of the slope to the horizontal distance, that is, the percentage slope tan 100%, where is the angle between the slope and the horizontal plane.

For example, "car climbing" is 30%, according to the above formula: tan 100% = 30%, that is, tan = 30 100, check the trigonometric function table to get 16°42", i.e. the steepest gradient that the car can climb is 16°42" 。

If the angle is directly marked on the "car climbability" in the car technical specification, it refers to the steepest slope that the car can climb. According to the regulations of the automotive industry, only the percentage slope is in line with the standard, and if only a number is marked, it is actually a percentage number.

To be clear, some people are wrong to interpret the percentage value of "car grade" as the direct steepest slope that the car can climb.

For cars that often drive in cities and on good roads, the maximum climb is about 10°. For trucks, sometimes it is necessary to drive on bad roads, and the maximum climbing degree should be around 30%. The off-road vehicle should be driven in a roadless area, and the maximum climbing degree should reach more than 30°.

The power of the car, the fuel economy of the car, the braking of the car, the handling and stability of the car, the driving smoothness of the car, the passability of the car, the emission pollution and noise pollution of the car, and some other properties, such as: light operation and maneuverability.

Power, fuel economy, braking, handling stability, ride smoothness, emission pollution and noise.

The size of the approach, departure and longitudinal passing angles are important geometric parameters to reflect the passability of the car. A car with good passability (off-roading) can pass through all kinds of bad roads and roadless areas (such as soft ground, uneven ground, etc.) and various obstacles (such as steep slopes, side slopes, trenches, steps, bushes, water barriers, etc.) at a sufficiently high average speed. Cars with poor passability will be unable to cope with bad roads, roadless areas and various obstacles;

The larger the approach angle, the less likely it is that the front end of the vehicle will not be able to pass because it touches the ground. On the contrary, the smaller the approach angle, the more likely it is that the front end of the vehicle touches the ground and cannot pass;

The departure angle refers to the angle between the tangent line of the rear wheel and the ground when the car is fully loaded and stationary;

The larger the departure angle, the less likely it is that the rear of the vehicle will not be able to pass because it touches the ground. On the contrary, the smaller the departure angle, the more likely it is to pass because the rear of the vehicle touches the ground;

The size of the longitudinal passing angle is determined by the wheelbase of the car and the minimum ground clearance. When the wheelbase is the same, the smaller the minimum ground clearance, the easier it is to support the bottom. When the minimum ground clearance is the same, the longer the wheelbase, the easier it is to support the bottom;

A good off-road vehicle can easily climb over a large slope, drive into a river at a certain depth, or drive at high speed on a rugged mountain road, and there is no need to worry about stopping and getting on and off the road. It can make you more likely to go where you want to go than other vehicles, allowing you to experience the feeling of conquering nature;

For the sedan, although we don't expect it to be able to go up the hill and down like the off-road vehicle, due to the low chassis, many owners have encountered the painful experience of supporting the bottom;

Because the transmission parts of the car, radiators, ternary cuihua and other devices are installed on the chassis of the car, especially the three-way catalytic converter, most of the interior is the catalyst carrier formed by honeycomb pottery, which is easy to break after the bottom collision, so that the catalytic converter and exhaust system are blocked, which directly affects the exhaust purification of the vehicle.

Power, safety, energy consumption performance, and stable performance.
