Do You Need to Press the Brake When Shifting Gears While Driving an Automatic Transmission Car?

When shifting gears while driving an automatic transmission car, you do not need to press the brake. The gears of an automatic transmission include: 1. P (Parking) gear for parking and starting; 2. R (Reverse) gear for reversing; 3. N (Neutral) gear; 4. D (Drive) gear for forward movement; 5. L (Low) gear for low-speed driving; 6. S (Sport) mode; 7. OD (Overdrive) gear. The correct way to use an automatic transmission is: 1. Start the vehicle in P or N gear, shift out of P gear by pressing the brake, turn on the power while pressing the brake, shift to N gear, and after ignition, shift to D gear to move forward directly; 2. When switching between N, D, and L gears, there is no need to press the shift button. When shifting from L gear to lower restricted gears, press the shift button, but when shifting from lower to higher gears, there is no need to press the shift button; 3. Do not shift into N gear to coast while driving; 4. Do not push into P gear while driving; 5. After driving, you must turn off the engine and shift into P gear before you can remove the key.

Can Motorcycles Select License Plates on the Traffic Management 12123 Platform?

Motorcycles can select license plates on the Traffic Management 12123 platform. Below are the specific details for online plate selection: Preparation in Advance: First, in areas with license plate restrictions, ensure that you have obtained the required quota. Schedule an online plate selection appointment via the online vehicle management office or its customer service hotline. Note that internet-based plate selection can only be performed within one day prior to the scheduled service date. Second, prepare the vehicle's certificate of conformity in advance, as the process requires inputting the vehicle's frame number, certificate of conformity number, or import goods certificate number. Completing the Process at the Vehicle Management Office: After completing the plate selection, the system will prompt you to visit the vehicle management office within a specified timeframe to complete the registration process. Failure to do so will result in the selected license plate becoming invalid, and you will be unable to use the online plate selection service for two years.

Can motorcycles be parked in car parking spaces?

Motorcycles can be parked in car parking spaces. The full name of a parking space is motor vehicle parking space, and any motor vehicle recognized by the state can be parked there. Motorcycles are also a type of motor vehicle, and as long as they have legal license plates, they can be parked in these spaces. Areas where parking is not allowed: Road shoulders marked with yellow no-parking lines indicate areas where roadside parking or stopping is prohibited. The length of the line indicates the extent of the no-parking zone. Yellow grid lines mark areas where parking is prohibited for any reason. These are typically used at intersections, entrances, and exits where temporary parking could cause traffic congestion. Special areas such as within 30 meters of bus stops, gas stations, emergency stations, and in front of fire stations do not allow temporary parking. No parking is allowed at intersections, railway crossings, sharp curves, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, or within 50 meters of these locations. Parking is also prohibited in areas where there are barriers separating motor vehicle lanes from non-motor vehicle lanes or sidewalks, as well as on crosswalks and construction zones.

What Happens When a Motorcycle Cylinder is Damaged?

Here are the specific manifestations of motorcycle cylinder damage: Engine Cylinder Head Leakage: This causes poor sealing between the cylinder head and the cylinder block, ultimately leading to leakage. Due to the leakage of oil and water, the leaking area is accompanied by splashes of oil and water, along with the sound of gas mixed with liquid splashing. Reduced Cylinder Pressure: Compressed gas inside the cylinder will leak through gaps, either escaping or entering other cylinders. This ultimately leads to unstable engine operation. Oil and Water Leakage: Coolant and engine oil generate a certain delivery pressure under the action of the water pump and oil pump. If the cylinder gasket is damaged, it will cause leakage of coolant and engine oil, or even mixing of the two, leading to deterioration of both. Gas Entering Oil or Water Passages: When high-pressure gas enters the oil or water passages, it will affect the engine's cooling and lubrication, leading to increased engine temperature and accelerated wear of engine components. Additionally, a large number of bubbles can be seen emerging in the expansion tank.

What is the function of the tube under a motorcycle engine?

The tube under a motorcycle engine is a breather tube, which releases internal pressure from the engine during operation. Below are specific details about motorcycle structures: Engine Block: The engine block consists of three parts: the cylinder head, cylinder body, and crankcase. The cylinder head is cast from aluminum alloy with cooling fins. Modern four-stroke motorcycle engines adopt an overhead valve, chain-driven, overhead camshaft configuration. Crankshaft and Connecting Rod: Motorcycle engine crankshafts use a combined structure, assembled from left and right half-shafts and a crank pin. The main journals of both half-shafts are equipped with ball bearings to support the crankshaft in the crankcase. The ends of the crankshaft are fitted with a flywheel, magneto, and clutch drive gear. Carburetor: The carburetor is a crucial component of the motorcycle's fuel supply system, located between the air filter and the engine intake. Its structure mainly comprises a float chamber and a mixing chamber. Lubrication System: Four-stroke engines use a combination of splash lubrication and pressure lubrication. Two-stroke engines typically employ a mixed lubrication method, blending gasoline with a certain proportion of QB-grade gasoline engine oil.

What documents are required for the first maintenance of a new car?

The items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; first maintenance certificate; vehicle's purchase invoice. Take these to the designated first maintenance institution for the vehicle's first maintenance. Note: Make an appointment with the 4S store in advance. The first maintenance refers to the initial maintenance after the new car has been driven. The specific time varies by car, usually after driving 1,000 to 3,000 kilometers. The car needs to participate in the first maintenance in time, neither in advance nor delayed. The realization of the first maintenance marks the end of the car's break-in period, and it can now be driven according to the standard load and normal speed required by the car. The time for the first insurance is calculated based on the date of picking up the car. There are two indicator values for the first maintenance time: mileage and time. Whichever comes first is the standard. The first maintenance items include: changing the engine oil and oil filter, cleaning the air filter, checking whether various oil levels are normal, checking whether the generator belt and wiper blades are damaged, checking whether the tire pressure is normal, and checking whether the tires are damaged or bulging, etc. Required time: It takes about 2 hours to complete all the work. The most important part of the first maintenance for a new car is changing the engine oil and oil filter. When changing the engine oil, the oil filter must be replaced together. When selecting the engine oil, refer to the "Vehicle Usage and Maintenance Manual," as different models specify different engine oil grades. Maintenance precautions: Do not rinse the inside of the car body with water: Many people clean their cars themselves during holidays, washing the body with water and scrubbing with a cloth. Here, it is important to remind that the inside of the car body does not need to be directly washed with water. If the floor mats are dirty, you can use a vacuum cleaner or take them out, brush them with detergent, dry them, and then put them back. There are many holes under the rubber mats on the floor of the driver's cabin. If water enters, it will not dry but will flow through the holes to parts like the gearbox, causing erosion and corrosion. The better approach is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is insufficient, it is recommended to drain the antifreeze and add the same brand of antifreeze from the beginning. Since different brands of antifreeze have different chemical functions, various functional preservatives can corrode other functional preservatives. Different brands of antifreeze use different preservatives. Do not mix them to avoid unnecessary trouble. Do not lubricate tire bolts and nuts: When the bolts on a moving car rust, they are usually oiled to make them work properly again. To prevent the bolts and nuts on the wheels from rusting, some people apply lubricating oil to them, but this brings necessary risks to safe driving. When the car is driving at high speed, the bolts and nuts can be easily loosened or even fall off, leading to driving failures. When promoting an EFI car, do not step on the accelerator: The promoter of an EFI car is different from that of an ordinary car. Its fuel injection control device can actively adjust the fuel supply based on the promoter's temperature and working conditions, making the promoter run smoothly.
