What Causes the Car to Shake When Driving at High Speeds?

Causes of car shaking at high speeds are as follows: Severe engine carbon buildup: The most common cause of car shaking is a dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector can be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. Solution: Clean the fuel system and check the idle control valve for carbon buildup, then clean it thoroughly. Ignition system issues: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or weak spark plug firing can also cause such symptoms. Solution: Inspect the spark plugs for excessive carbon buildup and replace them if necessary. Unstable fuel pressure: Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor can lead to car shaking. Solution: Check the fuel pressure and replace components if needed. Aging engine components: Car shaking can also be related to worn engine mounts. Engine mounts act as the engine's shock absorption system, absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can be transmitted to the steering wheel and cabin, causing shaking at idle. Solution: Replace the components.

How Does the Cruise Control System Work?

The working principle of the cruise control system is: in the vehicle cruise control system, electronic devices can automatically adjust the engine throttle opening according to changes in driving resistance to maintain a constant driving speed. Precautions for using the cruise control system include: 1. For safety reasons, do not use the cruise control system in heavy traffic or during severe weather conditions such as strong winds or heavy rain; 2. When using the cruise control system, pay attention to whether the CRUISE indicator light on the dashboard is flashing; 3. When driving on steep slopes, the cruise control system should be turned off immediately; 4. During downhill driving, avoid accelerating the vehicle; 5. To prevent the cruise control system from malfunctioning, turn off the cruise control switch when the system is not in use.

What Causes the Jerking Sensation During Car Acceleration?

Possible causes of jerking sensation during acceleration are as follows: Sludge in the transmission: Acceleration jerking and shuddering are often related to issues in the engine's fuel system, ignition, or intake systems. One possible cause is sludge buildup in the transmission fluid, which can circulate and clog the oil passages in the valve body, leading to jerking. Over time, this can result in transmission overheating, impact, slippage, and a series of other transmission problems. Engine fuel system: Next is the engine fuel system. The importance of engine oil is well-known—it provides sufficient lubrication, reduces resonance, and enhances engine smoothness. Prolonged oil deficiency can cause mild symptoms like insufficient power and increased fuel consumption, or severe consequences such as piston knocking and mechanical damage to related components. Additionally, fuel pump failure or clogged fuel filters can also reduce engine power. Intake system: Besides fuel, the engine also requires air. If components like the air filter or throttle body are clogged or malfunctioning, leading to insufficient air intake, the car may experience weak acceleration, slow speed increase, and jerking. The ignition system should not be overlooked either—if spark plugs misfire, leak, or fail to atomize properly, it can also affect engine acceleration.

What Precautions Should Be Taken During the Break-in Period of New Tires?

Precautions to be taken during the break-in period of new tires are as follows: Avoid sharp turns or sudden braking: Within the first 500 kilometers of a new car's break-in period, new tires have not yet reached optimal adhesion. It is advisable to avoid sudden braking during rapid turns as much as possible. Control maximum speed and RPM: Within the first 2,500 kilometers of a new car's break-in period, drive gently. The maximum speed should not exceed 100 kilometers per hour, and the RPM should not exceed 2,500 during the break-in period. Avoid overloading: Operating a new car at full load during the break-in period can cause damage to mechanical components. Therefore, within the first 1,000 kilometers of driving, the general load should not exceed 75-80% of the rated load capacity.

How many kilometers should a car run for its first maintenance?

Generally, a car should undergo its first maintenance after running approximately 5,000 kilometers. The first maintenance refers to the initial servicing after the car has been driven. The inspection items include: 1. Checking the coolant level of the car; 2. Checking the brake and clutch fluid levels; 3. Checking the steering oil tank level and whether there are any oil leaks at the oil pipe interfaces; 4. Inspecting the battery fluid level and the windshield washer fluid tank level; 5. Examining the tension and aging condition of the belts for the generator, air conditioning, water pump, and power steering pump. The purposes of the first car maintenance are: 1. Ensuring the vehicle is in good performance condition; 2. Effectively improving the vehicle's efficiency and reducing the wear of parts and tires; 3. Enhancing driving safety; 4. Preventing vehicle breakdowns; 5. Reducing noise and environmental pollution; 6. Maintaining the vehicle's appearance cleanliness and preventing damage.

What is the indicator for insufficient engine oil?

When the car's engine oil is insufficient, an indicator light resembling a "teapot" shape, which is the oil pressure warning light, will appear to alert the driver of low oil levels. At this point, the driver should promptly visit a nearby gas station or auto repair shop to replenish the engine oil to prevent further damage to the engine due to insufficient lubrication. Introduction to Engine Oil: Engine oil, also known as engine lubricant (English name: Engine-oil), serves multiple functions including lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the "blood" of a car. Composition of Engine Oil: Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties, while additives compensate for and enhance the performance shortcomings of the base oil, imparting new characteristics. Additives are an essential part of lubricating oil.
