Reasons for Car Shaking at Idle Speed?

When a car shakes at idle speed, it is usually due to issues with components such as the ignition system, oil pressure, throttle valve, or fuel injectors. Below are the specific causes and solutions: 1. Dirty throttle valve or fuel injectors: This is the most common cause of car shaking at idle. Excessive carbon deposits can prevent the fuel sprayed by the injectors from entering the cylinder properly, as most of it is absorbed by the carbon deposits. This leads to an overly lean air-fuel mixture, making the car difficult to start. After the car starts, the fuel attached to the carbon deposits is absorbed and burned, causing the engine's air-fuel mixture to become too rich. The unstable state of the air-fuel mixture results in car shaking at idle. Solution: Clean the throttle valve and remove engine carbon deposits promptly. 2. Unstable oil pressure: For this issue, it is recommended to visit a 4S shop for inspection, as professional diagnostic equipment is required. Items to be checked include fuel supply pressure and the intake pressure sensor. Solution: Check the oil pressure and replace any damaged components if necessary.

What is the difference between Volkswagen DJM and EA211 engines?

The following are the differences between DJM and EA211: 1. Different references: EA211 does not refer to a specific engine; it is an engine platform under Volkswagen, serving as the general code for all Volkswagen engines with a displacement below 1.6 liters. DJM is a 1.5-liter naturally aspirated engine under the EA211 platform, matched with models such as Santana, Jetta, and Bora. 2. Different included engines: EA211 is an engine developed by Volkswagen based on the MQB platform, including 1.4L four-cylinder turbocharged engines, 1.6L four-cylinder naturally aspirated engines, 1.0L three-cylinder naturally aspirated engines, and 1.2L four-cylinder turbocharged engines, mainly installed in compact cars like Polo, Golf, Lavida, and Bora. DJM is a specific model of the EA211 engine, a 1.5L naturally aspirated version with a maximum horsepower of 116 HP, a maximum power of 85 kW, and a maximum torque of 150 N·m, making it an economical engine.

What to Do If Someone Scratches Your Car and Leaves?

Since leaving the scene after a minor car scratch without awareness does not constitute hit-and-run, generally the other party only needs to pay compensation even if found by traffic police. If the accident is minor, with no casualties or significant property damage, it will not constitute the crime of traffic accident. Meanwhile, hit-and-run is defined as fleeing to evade legal responsibility. If the at-fault party had no such intention, it cannot be classified as hit-and-run. The process for car insurance claims is as follows: 1. Accident Liability Determination: In case of an accident, immediately report to the police and have the traffic police determine liability. 2. Report to Insurance Company: An insurance adjuster will arrive at the scene to investigate and confirm the situation. 3. Vehicle Repair: Generally, insurance companies recommend repairs at their partnered shops, but car owners can also choose on their own. 4. Claim Settlement: Submit the repair invoice to the insurance company for claim settlement.

Can the Volkswagen Sagitar flywheel noise issue be left unrepaired?

It can be left unrepaired, but timely handling is necessary. This situation may occur due to foreign objects stuck in the middle of the flywheel, or possibly because a screw on the flywheel has become loose. The flywheel is not a component of the transmission; it is a part of the engine, with the transmission connected to the flywheel. Below is relevant information about the automotive flywheel: Definition: A disc-shaped component with significant rotational inertia, functioning similarly to an energy storage device. For a four-stroke engine, power is generated once every four piston strokes—only during the power stroke, while the exhaust, intake, and compression strokes consume energy. Function: The flywheel possesses considerable rotational inertia. Since the power strokes of each cylinder in the engine are not continuous, the engine speed fluctuates. When the engine speed increases, the kinetic energy of the flywheel rises, storing energy; when the engine speed decreases, the flywheel's kinetic energy diminishes, releasing energy. The flywheel helps reduce speed fluctuations during engine operation.

What is the fuel tank capacity of the Buick Excelle GT in liters?

The fuel tank capacity of the Buick Excelle GT is 44 liters, which is the officially published data. Owners who have purchased the Buick Excelle GT can also check this information on the vehicle's configuration sheet. The Buick Excelle GT requires 92-octane gasoline, with a fuel consumption of 5.2 to 5.9L per 100 kilometers. A full tank can provide a driving range of approximately 746 to 846 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel added may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to a safe fill level, leaving some space between the safe fill level and the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the specified tank capacity.

Will a sudden drop in temperature cause a decrease in car tire pressure?

A sudden drop in temperature will cause a decrease in car tire pressure. Due to the low temperatures in winter, the tire pressure will also decrease due to thermal contraction. If the tire pressure is not appropriately increased at this time, it will not only increase the car's fuel consumption but also accelerate the wear of the car tires. In winter, the rubber of tires becomes harder and more brittle, and the friction coefficient decreases. This means that the tire pressure should not be too high, but it should also not be too low. If the external temperature is low and the tire pressure is too low, soft tires can accelerate aging and increase contact with the ground, leading to faster friction and reduced tire lifespan. Therefore, tire maintenance is very important. Consider replacing your tires with better winter tires. Due to the cold weather, tire rubber becomes harder compared to summer. Even though many cars are equipped with all-season tires, icy and slippery roads can still test the tires' grip. For driving safety, it is necessary to switch to winter tires. Pay attention to the vehicle's tire pressure to ensure that the front and rear tire surfaces on each side fully contact the ground, achieving optimal grip. At the same time, appropriate tire pressure can reduce road vibrations and enhance driving comfort.
