After modifying the gear ratio of Haval H5, the engine speed will be higher when driving at the same speed and using the same gear compared to before. Gear Ratio: The gear ratio is the ratio of the angular velocities of two rotating components in a mechanism, also known as the speed ratio. The gear ratio between component a and component b is i=ωa/ωb=na/nb, where ωa and ωb are the angular velocities of components a and b, respectively; na and nb are the rotational speeds of components a and b, respectively. Calculation Method: Reduction ratio = input speed ÷ output speed, which is the ratio of the connected input speed to the output speed. For example, if the input speed is 1500r/min and the output speed is 25r/min, then the reduction ratio is: i=60:12.

What is the lever next to the steering wheel for?

The lever below the car steering wheel can be moved up, down, left, and right. The lever on the left side of the steering wheel is for operating the car lights, while the lever on the right side is for the windshield wipers. Below are the functions of these two levers: 1. Functions of the left lever: Pushing the lever up activates the right turn signal, pushing it down activates the left turn signal. Turning the lever to the first small notch switches on the parking lights, and turning it to the second small notch switches on the headlights. Pulling it up activates the car's flashing light device. 2. Functions of the right lever: Pushing the right lever down turns on the windshield wiper function, which is used during rain or when the front windshield is not clear. The wipers have three modes: high, medium, and low, all adjustable via the lever. There is also a button on the lever for the wiper washer function. Both levers are frequently used during daily driving, so it is important to understand their functions and how to use them properly.

What happens if the first point is steered too early when reversing into a parking space?

Steering too early may result in failing to enter the garage, but there is slightly more room for adjustment when steering early compared to steering late. Below is relevant information about reversing into a parking space: 1. Overview: Reversing into a parking space has been a mandatory test item for obtaining a small car driver's license since 2013. It assesses the driver's ability to maneuver the vehicle in a confined space. Reversing into a parking space is one of the assessment points in the driver's test, requiring the driver to correctly reverse the vehicle into the garage from both sides while in motion. There is a time limit for this maneuver during the test. 2. Methods: There are three most common types of reversing into a parking space. The first is the "non"-shaped reverse parking, commonly found in large shopping malls. The second is the "one"-shaped reverse parking by the roadside, also known as parallel parking. The third is the less common diagonal reverse parking. 70% of driving school students find parallel parking more challenging.

What is the display screen in front of the steering wheel called?

The platform in front of the steering wheel is called the center console. Below is a related introduction to the center console: 1. Introduction: The platform in front of the steering wheel is called the center console, which integrates air vents, a central display screen, and many functional buttons. The vehicle's center console is very important as it incorporates numerous functions. 2. Design: The design of the center console is equally important. Some vehicles feature a highly futuristic design, while others emphasize a sporty feel. Some center consoles may not be as visually appealing but prioritize practicality. Designers must consider many factors when designing the center console, as many functional buttons need to be operated while driving. A well-designed console allows the driver to operate it without compromising driving safety, whereas a poorly designed one may reduce convenience or even affect driving safety. 3. Composition: The center console is generally divided into several areas. The leftmost section in front of the steering wheel is the instrument panel, which displays a lot of useful information. The middle area between the driver and front passenger is typically the multimedia control zone, and below it is the air conditioning control zone.
