Why Can't the Manual Transmission Engage Gear but Can Do So After Engine Shutdown?

Manual transmission cannot engage gear but can do so after engine shutdown due to incorrect gear position or lack of antifreeze. Below are the specific reasons: Incorrect gear position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) position when starting. If it's in R (Reverse) or D (Drive), the engine won't start. Some manual transmission vehicles also won't start if the clutch isn't depressed. Lack of antifreeze: Some car owners add water or inferior antifreeze, which can cause the entire cooling system to freeze in extremely cold winter conditions. This may lead to engine block cracking, preventing the water pump from functioning, resulting in failure to start and damage to other engine components.

Is it normal for a car's fuel tank cap to release gas when opened?

It is normal for a car's fuel tank cap to release gas when opened. Here is the relevant explanation: Pressure release: Gasoline is a highly volatile liquid. In hot summer conditions, the fuel tank is normally sealed off from the external environment to prevent fuel vapor from escaping. The fuel pump inside the tank also generates heat during operation. Both gas and liquid expand when heated, with gas having a much higher expansion rate than liquid. However, the entire fuel tank is a sealed space. As a result, the gaseous gasoline sealed inside the tank creates pressure that exceeds the external atmospheric pressure. When the fuel tank cap is opened, the pressurized gaseous gasoline is released. Carbon canister blockage: During summer, the fuel inside the tank is more prone to an imbalance between internal and external pressure. The rapidly rising temperatures may cause the carbon canister to temporarily fail to handle this pressure imbalance promptly, which can lead to the hissing sound when opening the fuel tank cap.

Will I get points deducted for driving at 127 km/h on a highway with a 120 km/h speed limit?

Driving at 127 km/h on a highway with a 120 km/h speed limit will not result in point deductions. Here are the specific details regarding highway speeding: 1. Penalties based on speeding severity: Speeding within 10% of the limit results in a warning; exceeding the limit by 10% to 20% incurs a 100 RMB fine and 3 penalty points. 2. Electronic police speed detection: Whether a driver is speeding is determined by electronic police speed monitoring. Highway speed cameras have an error margin, typically around 2%, and usually record speeds slightly slower than the actual speed. 3. Safety first: Speeding increases the risk of accidents as drivers may not have enough time to react, potentially leading to traffic safety incidents. When driving on highways, safety should always be the top priority.

What is the car depreciation rate?

Fixed asset depreciation rate is related to the depreciation period, so the depreciation period should be determined first. The specific details are as follows: Depreciation rate: 11% for the first 3 years, 10% from the 4th year onwards, and 9% for the last 3 years. For the first 3 years, the annual depreciation rate is 11%, with a total depreciation rate of 33% over 3 years. From the 4th year onwards: the annual depreciation rate is 10%, with a total depreciation rate of 40%; for the last 3 years, the annual depreciation rate is 9%, with a total depreciation rate of 27%. According to tax regulations for passenger cars: the depreciation period is 5 years, with a residual value rate of 5%. Residual value: The higher the depreciation rate, the worse the vehicle's condition and the lower the residual value. The depreciation rate is the same as the newness rate, both of which can be used to indicate the value of a used car (car residual value).

What are the methods for car paint repair?

For minor scratches on the car paint surface where the damage is only on the top layer of the paint, complete repair can be achieved through waxing. If the scratch is slightly deeper, partially removing the top paint but without damaging the primer or causing significant deformation, the paint surface can still be well restored through waxing. Below is an introduction from a 4S store: Introduction to 4S stores: A 4S store, fully known as an automobile sales service 4S store, is a car sales enterprise that integrates four functions: vehicle sales, spare parts, after-sales service, and information feedback. Services of 4S stores: The core competitiveness of a car 4S store lies in winning customers with high-quality services. At a car 4S store, consumers can access all value-added services regarding car information, market trends, after-sales service, maintenance tips, and spare parts supply. Whether it's a complete vehicle or spare parts, authenticity and quality are guaranteed, relieving consumers of any concerns about after-sales service, repairs, and maintenance.

How Many Gears Does a Car Have?

Cars have 4-8 gears. Here are the specific introductions to the common automatic transmission gears currently: P (Parking Gear): When the car is parked and not in use, the gear is in this position, where the wheels are mechanically locked to prevent rolling. The vehicle must come to a complete stop before engaging the P gear, otherwise the mechanical parts of the automatic transmission may be damaged. R (Reverse Gear): Used for reversing. Unlike manual transmission cars, automatic transmission cars cannot use half-clutch, so special attention should be paid to the control of the accelerator pedal when reversing. Usually, the safety button on the shift lever must be pressed before moving the lever to the "R" gear. Never force the shift to the "R" gear before the vehicle comes to a complete stop, otherwise the transmission may be severely damaged. N (Neutral Gear): Used for temporary stops (such as at a red light). Note that this gear position indicates neutral. To prevent the vehicle from rolling on a slope, the brake must be applied.
