What Are the Causes of a Lean Air-Fuel Mixture in Cars?

Introduction to the causes of a lean air-fuel mixture in cars: In terms of the fuel system, a lean mixture essentially means insufficient fuel supply, resulting in a lower proportion of gasoline in the mixture. Insufficient fuel supply can be categorized into two types of faults: those outside the carburetor and those within the carburetor. Below are the detailed explanations: 1. Main causes of insufficient fuel supply outside the carburetor: (1) The fuel filter is clogged. (2) There is a blockage in the fuel line or the fuel pipe is damaged. (3) Loose or leaking fuel pipe connections. 2. Main causes of insufficient fuel supply within the carburetor: (1) The carburetor's fuel inlet is clogged, preventing smooth fuel flow from the external fuel system into the float chamber. (2) The float chamber fuel level is too low or the float is stuck. (3) The needle valve is stuck or other fuel outlets are clogged. (4) The main jet is clogged or improperly adjusted. Additionally, leaks in the intake manifold gasket or the carburetor base gasket can also cause the air-fuel mixture to become too lean.

Do Front-Wheel Drive Cars Have a Differential?

Front-wheel drive cars do have a differential. Both front-wheel drive and rear-wheel drive vehicles have only one differential, which is installed on the drive axle. The car differential is a mechanism that allows the left and right (or front and rear) drive wheels to rotate at different speeds. It mainly consists of left and right half-shaft gears, two planetary gears, and a gear carrier. Below is some relevant information about differentials: 1. The function of the differential is to allow the left and right wheels to roll at different speeds when the car is turning or driving on uneven surfaces, ensuring that both drive wheels perform pure rolling motion. The differential is installed to adjust the speed difference between the left and right wheels. 2. A standard differential consists of components such as planetary gears, a planetary gear carrier (differential housing), and half-shaft gears. The engine's power is transmitted through the drive shaft into the differential, directly driving the planetary gear carrier, which then drives the left and right half-shafts via the planetary gears, respectively powering the left and right wheels. This adjustment by the differential is automatic and involves the "principle of minimum energy consumption," meaning all objects on Earth tend to a state of minimal energy consumption.

What does 5W-40 engine oil mean?

5W-40 is a very common type of engine oil. The specific details are as follows: 1. "W" stands for winter. 2. "5" indicates the cold-start performance of the oil. The smaller the number, the stronger the oil's cold resistance, making it easier to start the engine at very low temperatures. 3. "40" represents the kinematic viscosity standard at 100 degrees Celsius (between 12.5mm2/s and 16.3mm2/s). The larger the number, the better the protection performance under high-temperature conditions. Vehicles suitable for 5W-40 oil: (1). German cars usually have turbocharged engines with larger gaps, so 5W-40 (high viscosity) oil is required. Most European cars also use 40-viscosity oil. (2). For cars older than 7 years, the engine is prone to aging and severe wear, so higher viscosity 5W-40 oil should be used. (3). For cars frequently driven on highways, the engine's heat generation and wear are more severe, so it is recommended to use 5W-40 oil.

What are the reasons for idle shaking in Changan CS55?

The idle shaking in Changan CS55 can be attributed to the following four reasons: 1. Severe engine carbon deposits causing idle shaking: When there is excessive carbon buildup inside the engine, the gasoline sprayed by the cold start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. In this situation, the engine only starts easily once the carbon deposits are saturated with gasoline. After starting, the gasoline adsorbed on the carbon deposits is drawn into the combustion chamber by the engine's vacuum suction, making the air-fuel mixture too rich. The fluctuating air-fuel mixture leads to idle shaking after a cold start. 2. Ignition system issues causing idle shaking: 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 lead to such symptoms. 3. Unstable fuel pressure causing idle shaking: Abnormal fuel supply pressure or malfunctioning intake pressure sensors can cause vehicle shaking. If the fuel pump's supply pressure is abnormal or the intake pressure sensor provides incorrect readings or malfunctions, it can result in idle shaking. 4. Aging engine components causing idle shaking: Engine mounts act as the engine's shock absorption system, absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can transfer to the steering wheel and the cabin, causing shaking during idle.

How Often Should the Differential Oil of a Truck Be Changed?

Truck differential oil should be changed every 40,000 kilometers. Changing the differential oil prevents excessive wear of the vehicle's differential gears, which could lead to differential damage. The steps for changing differential oil are as follows: 1. Lift the vehicle and place a large container underneath to catch the used oil. Use an appropriate screwdriver to remove the inner and outer shells of the transmission. 2. When most of the oil has drained, remove the last oil pan. 3. Remove the oil pan gasket and clean any surrounding stains. If the gaps are not clean enough, use tools and cotton thread to thoroughly clean all the filtered parts of the transmission oil, then reinstall them one by one. 4. Wipe the surfaces of the replacement parts clean, reinstall the cleaned oil pan and gasket, and add the original manufacturer's oil.
