Why Does a Diesel Engine Shake at Idle?

Here are the reasons why a diesel engine shakes at idle: 1. Stuck fuel injector: A stuck or poorly atomizing injector in one cylinder causes that cylinder to not work or work poorly (blue-white smoke may be emitted from the exhaust). This can be checked using the cylinder cut-off method. 2. Uneven fuel supply from the injection pump: Uneven idle fuel supply from the injection pump leads to inconsistent cylinder operation at idle. 3. Low RPM: Improper idle adjustment (too low RPM) can be resolved by adjusting the idle fuel supply screw. 4. Improper valve clearance: Incorrect valve clearance (due to loose adjustment screws, abnormal wear, or abnormal wear of the valve pushrod) causes the cylinder to not work or work poorly. This can be fixed by adjusting the valve clearance. 5. Poor valve sealing, leading to suboptimal operation. 6. Engine overheating or insufficient oil (causing poor lubrication), making it difficult for engine components to operate smoothly.

Which switch is used for windshield defogging?

Windshield defogging is activated by pressing the defogger switch. Other methods for windshield defogging include: 1. Wiping it clean with a towel. 2. Turning on the car's heater to clear the fog. 3. Leaving a slight gap in the window to remove fog. 4. Using an automotive glass anti-fog spray. Here is some related information: 1. Reasons for windshield fogging are as follows: (1) Temperature difference between the inside and outside of the car. (2) The window temperature is lower than the outdoor temperature. (3) Temperature difference between the two sides of the window. 2. Methods for maintaining the glass include: (1) Using appropriate windshield washer fluid according to the season. (2) Applying automotive glass heat insulation film. 3. Functions of the glass include: blocking wind and rain, noise reduction and sound insulation, reducing wind resistance and guiding airflow, and protecting the safety of passengers.

Does a manual transmission need gearbox oil change?

New cars do not require it. If the driving time exceeds two years or the mileage exceeds 60,000 kilometers, the gearbox oil should be changed regularly. Expired or deteriorated gearbox oil can cause difficulty in shifting gears and wear on the transmission bearings. Below is relevant information about gearbox oil: 1. The main function of gearbox oil is to keep the shifting system clean and to lubricate and prolong the life of the transmission components. Due to differences in transmission design, gearboxes are divided into manual transmissions and automatic transmissions (further categorized into CVT, AMT, etc.). Each transmission design has different technical requirements. Even the same model of transmission configured in different vehicle models will have variations in torque, weight, speed, and structure. Therefore, the original manufacturer specifies its own dedicated gearbox oil. 2. Generally, an automatic transmission in a car requires an automatic transmission oil change every two years or every 40,000 kilometers. This varies depending on the vehicle model. For Japanese models, it is recommended to change the oil every 40,000 to 80,000 kilometers. Vehicles that frequently drive at high speeds are advised to change the oil approximately every 40,000 kilometers.

What does lightly pressing the brake pedal mean?

Lightly pressing the brake pedal means: pressing the brake pedal once, then releasing it, and pressing it again, repeating this process. This method is suitable for situations with low road friction coefficient, wading, or tire blowouts, where intermittent pressing of the brake pedal can help reduce speed. Below is an introduction to lightly pressing the brake pedal: 1. Applicable situations: (1) When temporary, slight deceleration is needed at high speeds; (2) When cornering; (3) When following a vehicle ahead and feeling the distance is getting too close, lightly pressing the brake pedal is necessary. 2. Brake pedal operations in vehicles can be divided into: slow braking (i.e., anticipatory braking), emergency braking, combined braking, and intermittent braking. Generally, during slow braking and emergency braking, before the wheels lock up or the vehicle stops, the clutch pedal should be fully pressed to prevent the engine from stalling and to facilitate speed adjustment. 3. Generally, pressing the brake pedal can be done in two steps, avoiding a single hard press: first, press the brake pedal with a force determined by the need—quick and forceful when the speed is high, gentle and steady when the speed is low; then, adjust the pressure based on various conditions. Pressing the brake pedal at high speeds can easily cause skidding. When the vehicle skids, the pressure on the brake pedal should be appropriately reduced to prevent the vehicle from veering off course and losing steering control.

What does 2.0xl mean?

In car models, XL indicates that the vehicle belongs to the luxury version. Other code knowledge extensions are as follows: 1. XE refers to the comfort version sedan. 2. XL refers to the luxury version sedan. 3. XV refers to the super luxury version vehicle. 4. XVNAVI is XV-NAVI, which refers to the super luxury version vehicle with a navigation system. Knowledge extension about the letter T is as follows: 1. T stands for turbocharging, indicating that the vehicle is equipped with a turbocharged engine. 2. A turbocharger is essentially an air compressor that increases air intake by compressing air. 3. It utilizes the inertial impulse of exhaust gases from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller compresses the air delivered through the air filter pipeline, pressurizing it into the cylinders. 4. As the engine speed increases, the exhaust gas discharge speed and turbine speed also increase synchronously, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable the combustion of more fuel, and correspondingly increasing the fuel quantity can enhance the engine's output power.

What is the function of an intercooler?

The function of an automotive intercooler is to reduce the intake air temperature of the engine. The intercooler is essentially a supporting component for turbocharging, and its role is to improve the engine's air exchange efficiency. Specific details are as follows: 1. The exhaust gas emitted by the engine is at a very high temperature, and the heat conduction through the turbocharger increases the intake air temperature. During the compression process, the air density increases, but this also causes the temperature of the air discharged by the turbocharger to rise with the increase in pressure, leading to a decrease in oxygen density, which affects the engine's effective charging efficiency. 2. If the turbocharged air enters the combustion chamber without cooling, it not only affects the engine's charging efficiency but also easily leads to excessively high combustion temperatures, causing issues such as knocking. Additionally, it increases the NOx content in the engine's exhaust, contributing to air pollution. 3. Reduces the engine's fuel consumption. 4. Enhances adaptability to high altitudes. In high-altitude areas, using an intercooler allows for a higher pressure ratio compressor, which enables the engine to generate more power and improves the vehicle's adaptability. 5. Improves turbocharger matching and adaptability.
