Does a car consume fuel if left idling without turning off the engine?

What Causes Engine Shaking When Parking?

Parking shaking may be caused by aging engine components, and car shaking is also related to aging engine mounts. Here is relevant information: 1. Excessive carbon deposits: If there is severe carbon buildup in the engine cylinders, it can lead to clogged spark plugs and valves, directly causing the car to shake during idling. If the car's acceleration performance has significantly declined and the shaking persists, consider cleaning the engine cylinders. 2. Fuel supply system malfunction: Unstable fuel pressure can easily cause inconsistent concentration of the air-fuel mixture, resulting not only in shaking but also unstable idling. First, consider replacing the fuel filter, as prolonged use may clog the filter element. Then check the fuel pressure bypassing the fuel filter; if abnormal, it could indicate a fuel pump issue. 3. Misfiring cylinders: This is one of the most common causes of engine shaking, if not the most common. The problem lies in the engine ignition coil or spark plugs. If the ignition coil malfunctions or the spark plugs fail to fire for some reason, the car will exhibit shaking.

What Causes Water on the Car Floor?

Possible reasons include water leakage from the door seals, which can be resolved by replacing the seals. Another cause could be clogged drainage holes under the windshield wiper baffle, allowing water to enter. Additionally, a blocked air conditioning drain hole may lead to leakage. If the sealing gasket on the door panel has come loose or wasn't properly secured, rainwater may seep in along a line, causing water accumulation under the floor mat. Below are the reasons for water ingress on the car floor: 1. Rust perforation in the chassis, allowing wheel splash to enter. Inspect carefully and seal or install a liner. 2. Clogged rainwater holes in the windshield cowl. Open the hood to check and clean them. 3. Damaged or ineffective door seals causing wind-driven water ingress. Inspect and replace if necessary. 4. Blocked sunroof drainage tubes, allowing water to enter from below the center pillar. Check and clear the blockage. 5. Poor sealing or rusted/loosened chassis screws causing water ingress. Inspect carefully and seal or tighten them.

Is the Parking and Card Retrieval Test Part of Subject 2 or Subject 3?

Parking and card retrieval is part of Subject 2. Below is a detailed introduction to the precautions for parking and card retrieval: 1. Avoid crossing the line: When entering the parking and card retrieval section, in addition to looking at the front of the car and aligning the body, you should also pay attention to the rearview mirror to prevent the rear wheels from crossing the line. 2. Find the correct position: During the test, control the speed, find the correct parking position, and stop in time. Otherwise, missing the correct position will make it impossible to retrieve (or swipe) the card, or reversing to adjust the position will result in failing the test. 3. Control the distance: Similar to parallel parking, the parking position for card retrieval must be well-controlled—you cannot cross the line, but you also cannot be too far away. Exceeding 500mm will result in a deduction of 100 points.

What are the advantages and disadvantages of 360-degree car mats?

The advantages of 360-degree car mats are water absorption, dust absorption, stain removal, sound insulation, and protection of the main unit, while the disadvantage is that universal mats are prone to slipping. It is recommended that car owners choose custom-fit car mats, which are safer and more aesthetically pleasing to use, help maintain effective interior space, and are less likely to slip. Below is an introduction to windshield washer fluid: 1. Cleaning performance: Windshield washer fluid typically has functions such as wetting, penetrating, and solubilizing, thereby serving the purpose of cleaning and removing stains. 2. Antifreeze performance: The presence of alcohol and ethylene glycol can significantly lower the freezing point of the liquid, thus serving an antifreeze purpose and quickly dissolving frost.

Is it necessary to install car floor mats?

It is highly necessary to install car floor mats for private vehicles. Below is an analysis of why floor mats should be installed based on their functions: 1. Floor mats integrate five major functions: water absorption, dust absorption, stain removal, sound insulation, and protection of the main carpet, making them an eco-friendly automotive interior component. 2. Car floor mats serve as interior decorations that maintain cleanliness both inside and outside the vehicle, adding aesthetic and comfortable touches. 3. The water absorption, dust absorption, and stain removal capabilities of car floor mats can effectively prevent residual moisture and dirt from shoe soles from causing slippage between the clutch, brake, and accelerator, thereby avoiding potential safety hazards and reducing the likelihood of interior contamination and damage. After all, cleaning floor mats is more convenient and economical than cleaning the interior.

Which country's engine is used in the BJ80?

BJ80's engine is provided by Liuzhou Wuling Liuji Power Co., Ltd., which is a domestic engine. The 2.3T version of the BJ80 engine has the model number B231R, with a maximum power of 170kw and a maximum torque of 280 Nm. The 3.0T version has the model number 6G30TQY, with a maximum power of 206kw and a maximum torque of 420 Nm. The following methods can be used for daily maintenance of the BJ80 engine: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance will deteriorate, causing various problems for the engine. To avoid faults, change the oil regularly according to usage conditions and keep the oil level moderate. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry dirt back to the lubrication parts, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking filters and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine works properly but also extends the overall lifespan of the radiator and engine.
