What Causes Body Shaking at Speeds of 110 to 120 km/h?

What Causes Hard Brakes?

Hard brakes can be caused by the following reasons: 1. Insufficient brake booster assistance: First, check if the vacuum tube of the brake booster is clogged. 2. Vacuum-related issues: Factors affecting vacuum include cracks in the atmospheric valve seat, fatigue damage to the diaphragm, cracks or failure of the vacuum valve seat, and malfunctioning vacuum hose valves. 3. Free travel issues: When a driver presses the brake pedal, braking does not start immediately but has a buffer time for a more comfortable feel. After the free travel ends, as braking enters the effective travel phase, the pedal force is transmitted through the brake pipeline system to each wheel. As the pedal force gradually increases, the driver's feel of the pedal also becomes heavier, and the vehicle speed slows down accordingly. No free travel or insufficient free travel can lead to hard brakes or excessive pedal force. 4. Jump value and jump point issues: From the design perspective of the booster, the jump value is not only a significant cause of hard brakes but also a quantitative indicator of hard braking. 5. Gap between the valve plug and the rubber reaction disc: Under normal conditions, both the atmospheric valve and the vacuum valve of the vacuum booster are closed. When the driver presses the brake pedal, at the moment the vacuum valve closes and the atmospheric valve opens, there is a gap between the valve plug and the rubber reaction disc. This gap value affects the jump value.

What Causes the Car to Shake When Releasing the Clutch?

The reasons for car shaking when releasing the clutch: 1. Uneven pressure distribution on the car's clutch, incorrect pressure position; 2. Excessive spring force of the clutch pressure plate, causing the clutch to shake; 3. Stiffness in components such as the release sleeve and release fork shaft; 4. Oil contamination or breakage of the friction disc lining; 5. Bent main or driven discs, uneven height of the release levers. The clutch is installed between the engine and the transmission, serving as the assembly component in the car's drivetrain that directly connects to the engine. Typically, the clutch is mounted together with the engine crankshaft's flywheel assembly, acting as the component that cuts off and transmits power between the engine and the car's drivetrain.

What Issues Should Be Considered When Ordering a Car?

When ordering a car, it is necessary to understand the model and the extent of price discounts, confirm the car information, and the order contract must be detailed. The specific details are as follows: Model and Price: Before ordering a car, you can first research the model online, including the basic configuration differences and the extent of price discounts. After gaining a preliminary understanding of the model and price discounts, negotiate with the sales consultant at the 4S store. It is advisable to compare options from multiple dealers. Car Information: Before ordering a car, confirm the model, chassis number, engine number, and color of the car you are purchasing. Especially ensure that the car code and the vehicle identification number are clearly stated to avoid any changes when picking up the car. Order Contract: Before signing the order contract, negotiate the price and any freebies. Pay attention to the type of order when drafting the contract. Additionally, clearly specify the costs for insurance and purchase tax agency services, including the deposit and pickup time. Liability for breach of contract should also be clearly defined to prevent future disputes. Regarding the deposit, try to pay as little as possible. After drafting the contract, carefully review it to avoid any omissions. Finally, sign the contract and provide your contact information to complete the car order.

Is Wheel Alignment Necessary When Replacing Car Tires?

Wheel alignment is necessary when replacing car tires, as it is beneficial for both the tires and suspension, and most importantly, it ensures safety. However, it must be performed accurately; otherwise, it can pose significant risks. The functions of wheel alignment include: 1. Automatically returning the steering wheel to its original position after turning, improving driving comfort; 2. Keeping the steering wheel straight, maintaining the vehicle's straight-line driving, and enhancing driving safety; 3. Reducing fuel consumption, minimizing suspension component wear, and preventing abnormal tire wear. Wheel alignment is based on the four-wheel parameters of the vehicle, adjusted to ensure optimal driving performance and reliability. The installation of a car's steering wheels, steering knuckles, and front axle has a specific relative position, and this installation with a certain relative position is called steering wheel alignment.

What is the minimum ground clearance of the Emgrand?

The minimum ground clearance of the Emgrand is 138mm. The minimum ground clearance of the Emgrand refers to the distance between the lowest point (excluding the wheels) and the supporting surface, which indicates the vehicle's ability to pass over obstacles such as rocks and tree stumps without collision. A higher ground clearance for the Emgrand means better off-road capability, but if the ground clearance is too high, the stability at high speeds may decrease. The Emgrand is equipped with a new third-generation 1.5TGDI engine from the Jule Power series and a 7WDCT transmission, offering four driving modes: Sport, Comfort, Eco, and Sport+ Extreme. The dimensions of the Emgrand are 4700mm in length, 1850mm in width, and 1432mm in height, with a wheelbase of 2736mm. Generally, the ground clearance for sedans ranges between 110mm and 150mm, while SUVs have a ground clearance between 200mm and 250mm. However, the Emgrand's ground clearance is not static; it also depends on the load condition. Therefore, changes in the Emgrand's load should be considered when evaluating ground clearance variations. When selecting a vehicle, ground clearance can be one of the reference factors. The choice should depend on the vehicle's intended use and the road conditions. For well-paved urban roads, a vehicle with lower ground clearance can enhance stability and comfort. For frequent travel to remote areas or driving on rough terrain, a vehicle with higher ground clearance is advisable to avoid chassis scraping or damage, considering its off-road performance.

What does km/l mean?

km refers to the number of kilometers the car travels, l represents liters, and km/l refers to the fuel consumption per kilometer of the car. For car fuel consumption in km/L, a higher value is better, not lower. For example, comparing 1km/L and 2km/L, the latter clearly indicates a more fuel-efficient car. Below is an extended introduction: Factors affecting car fuel consumption: The amount of fuel a car consumes is not only related to the car itself but also to the driver's driving habits and road conditions. If the driving habits are poor and the car is frequently driven on congested roads, the fuel consumption will inevitably be relatively high.
