Car parameter questions, please ask, about car parameter configuration?

Wheelbase is the distance between two perpendiculars of two adjacent wheels on the same side of the vehicle and perpendicular to the longitudinal plane of symmetry of the vehicle. To put it simply, it is the distance from the center of the front axle to the center of the rear axle of the car. For cars with more than three axles, the axles have a wheelbase between two adjacent wheels from front to back, and the total wheelbase is the sum of the wheelbases.

Torque is the force that causes an object to turn. Engine torque is the torque that the engine outputs from the crankshaft end. Under the condition of fixed power, it is inversely proportional to the engine speed, the faster the speed, the smaller the torque, and vice versa, it reflects the load capacity of the car within a certain range.

Generally speaking, the maximum torque occurs in the range of medium and low engine speeds, and as the speed increases, the torque decreases. For example, the newly launched Beijing Hyundai Elantra sedan has a maximum torque of 162Nm at 4500rpm, which means that when the engine speed is 4500 rpm, the Elantra outputs the maximum torque of 162 Nm. Another example is FAW-Volkswagen's Audi, whose maximum torque is 210Nm 1750rpm-4600rpm, which means that this model of Audi sedan, when the engine speed is maintained between 1750 and 4600 rpm, the maximum torque output is 210 Nm.

The larger the wheelbase, the more comfortable it is to sit.

WheelbaseI think Erichuang has made it very clear!

As for torque, simply put, the greater the torque, the stronger the load capacity of the car, and vice versa, the smaller it is, in simple terms, the greater the torque, the greater the power of the car, and vice versa!

Power is the work done by the engine per unit time, and the greater the power, the higher the speed, and the torque is the torque output by the engine from the end of the crankshaft. The greater the torque, the greater the power of the car, that is, the more explosive it is, which is suitable for drag racing. Generally, sports cars have relatively high torque.

Torque in the truck, it is manifested as a large traction, the more things to pull, the stronger the climbing ability, how to see the speed of the car start and the acceleration speed is mainly to see the maximum torque of the burst point, the same displacement of the engine maximum torque of the lower the number of revolutions, the faster the start.

Horsepower determines top speed, torque determines acceleration.

You must have read it wrong.

This can't be the engine model.

Moreover, Yutong's engines do not start with zk, and they all use engines produced by Yuchai, Weichai, Cummins, Hino, Xichai and other manufacturers. ZK6936HGN Yutong bus is the engine selected Dongfeng Motor **** commercial vehicle engine factory, Guangxi Yuchai Machinery Co., Ltd. production of EQD210N-30, YC6J210N-3NG engine.

The model you mentioned represents.

ZK stands for Zhengzhou Yutong Bus.

The number 6 represents the passenger car category (1 represents the truck, 7 is the car, 2 is the off-road vehicle, 5 is special, etc.) and 936 represents the passenger car with a length of 9 meters.

HGN stands for Natural Gas Passenger Vehicle.

Maximum torque

Torque is an important parameter of engine performance, which refers to the average torque output from the crankshaft end when the engine is running, commonly known as the "rotational force" of the engine. The greater the torque, the greater the "Kaichun Liang Jin" output by the engine, the faster the crankshaft speed changes, and the better the car's climbing ability, starting speed and acceleration. Torque varies with the change of engine speed, too high or too low, the torque is not the maximum, only at a certain speed or in a certain speed range has the maximum torque, this range is the speed or speed range given when the maximum torque is marked.

The maximum torque generally occurs in the range of medium and low engine speeds, and as the speed increases, the torque decreases. The unit of torsional moment is Newton-meter (n·m) or kilogram·meter (kg·m).

The maximum torque is, of course, as large as possible. The lower the speed at which the maximum torque occurs, the better. The lower the maximum speed, the more effective it is when it stops and goes around the city, and the more powerful it is to start and the faster it is to lose with pants.

Hello. Number of springs 8 6 5: 8 front springs, 11 rear yellows, including 6 main springs and 5 secondary springs;

Axle load is the front and rear axle to bear the weight of the car, generally speaking, the axle load ratio lead collapse is the ratio of the front and rear axles to share the weight of the vehicle, curb weight refers to all the working devices and chassis with all the ancillary equipment of the car closed bending equipment, full of oil and water, not carrying people when the quality of the vehicle.

The rated mass is the maximum axle load mass of all axles of the special purpose vehicle and minus the axle load mass of all axles when the Huaiyuan special purpose vehicle is unloaded.

If you don't know how to ask me, you can ask me.
