How does the court determine vehicle ownership?

Motor vehicle registration certificate holder is generally regarded as the owner of the motor vehicle. In special circumstances, the actual investor should be considered as the decisive basis for determining vehicle ownership, rather than using public security authorities' motor vehicle registration as the indicator of ownership transfer. Concepts of actual vehicle owner vs. nominal owner: Article 71 of the General Principles of Civil Law stipulates: "Property ownership refers to the owner's rights to lawfully possess, use, benefit from, and dispose of their property." This shows ownership represents complete real right, exclusive right, absolute right, and right in rem. After the seller delivers the vehicle, they essentially lose the rights to possess, use, benefit from, and dispose of the vehicle. Their exercise of vehicle ownership becomes defective and virtually impossible, as the nominal owner can no longer actually control or benefit from the vehicle. China's vehicle registration system does not equate to ownership registration: According to the publicity methods of property rights, civil law theory uniformly considers delivery as the sole publicity method for movable property rights changes, while registration serves as the publicity method for immovable property rights. Following the principle of statutory property rights, the types, content, validity, and publicity methods (delivery, registration) of property rights should be stipulated by law, excluding administrative regulations, local regulations, and administrative rules. Current motor vehicle registration provisions are only established by departmental rules and documents issued by the Ministry of Public Security, which contradicts the principle of statutory property rights.

Should You Press the Accelerator When Starting a Manual Transmission Car?

During the second subject of the driving test, pressing the accelerator is not allowed, so it is possible to start without pressing the accelerator. The correct way to start is to engage the clutch halfway while giving some gas, then fully release the clutch. Engaging the clutch halfway while giving gas helps to minimize stalling, as the clutch and accelerator work together as part of the car's fuel supply system. By controlling the amount of pedal pressure: You regulate the throttle opening of the engine, controlling the air intake, while the computer controls the fuel supply, thereby managing the engine's RPM. First, release the clutch to the halfway point, then you can either press the accelerator or not. Once the car starts moving slowly, fully release the clutch. Starting on a flat road: Press the clutch all the way down. When the clutch reaches the halfway point, the car will start to vibrate. At this point, release the handbrake and then the clutch to start smoothly. During following traffic: If the car hasn't stalled, when driving in a queue on a downhill slope, avoid coasting in neutral over long distances as it can lead to loss of speed control and potential accidents. However, on short downhill slopes, you can follow the car in front at a slow speed. For slightly more experienced drivers, it's possible to shift into neutral, lightly press the brake with the right foot to maintain a safe distance from the car in front. Once the speed picks up slightly, shift directly into second gear, release the clutch, and press the accelerator to continue driving.

Does replacing a new engine control unit require decoding?

The engine control unit is part of the vehicle's electronic anti-theft system. Most vehicles require decoder rematching after replacement, while the remaining portion can automatically match. Functions of the engine control unit: The engine control unit is a high-tech electronic product that uses advanced technology to read vehicle data. It consists of a microcomputer and peripheral circuits, with the main component being the microcomputer and the core element being the CPU. This system continuously monitors whether the vehicle's emissions exceed standards based on engine operating conditions and then issues warnings. When a system malfunction occurs, the malfunction indicator light or check engine warning light illuminates, while the powertrain control module stores the fault information in memory. Through specific procedures, fault codes can be read from the PCM, allowing for quick and accurate determination of the fault's nature and location based on the fault codes. Common decoding methods: Capacitance decoding is used for models with pulse detection and waveform detection; resistance decoding typically applies Ohm's Law R (resistance) = U (voltage) / I (current) to calculate the decoding method on the vehicle; modifying the engine control unit mainly targets models such as Volkswagen, Skoda, and Audi, using decoding software like 5053 and decoding cable sets; commonly used decoding stabilizers and decoders are primarily for Korean vehicles. After installing imported stabilizers, due to the high starting current causing left and right bulb flickering, simply adding an additional single-lamp cable set can resolve the issue.

What is the difference between a three-cylinder and a four-cylinder engine?

The differences between a three-cylinder and a four-cylinder car are as follows: 1. Balance is different: For a 4-stroke engine, the main difference between a three-cylinder and a four-cylinder engine is the balance. The three-cylinder engine has poorer balance compared to the four-cylinder engine. 2. Ignition intervals differ: The firing order of a three-cylinder engine is generally 1-3-2, with an ignition interval angle of 240 degrees; the firing order of a four-cylinder engine is generally 1-3-4-2, with an ignition interval angle of 180 degrees. 3. Crankshaft balance differs: A three-cylinder engine uses a three-throw crankshaft, which can only achieve static balance without additional balancing measures and cannot achieve dynamic balance. A four-cylinder engine uses a four-throw flat crankshaft, which inherently achieves dynamic balance. 4. A three-cylinder car's engine has only three cylinders, while a four-cylinder car's engine has four cylinders: Generally, a four-cylinder engine runs more smoothly than a three-cylinder engine. 5. Cylinder bore and power performance differ under the same displacement: The cylinder bore of a three-cylinder engine is larger than that of a four-cylinder engine; in terms of power performance, a three-cylinder engine is more powerful than a four-cylinder engine.

What Causes Brake Pulling?

Brake pulling can be caused by the following reasons: 1. Unilateral brake pad wear or hub inner ring wear. 2. Unilateral tire wear, resulting in inconsistent friction on both sides. 3. Frame deformation causing uneven force distribution. 4. Differences in tire pressure, tread patterns, or wear levels between two sides can lead to unequal actual rolling radii, causing the vehicle to pull even without braking. 5. Uneven braking torque on left and right sides of the same axle, leading to unilateral deviation. Common causes include leaking wheel cylinders, rusted pistons, oil-contaminated drum brake shoes, or different surface roughness between brake discs/pads or drums/shoes.

How is car fuel consumption calculated?

Fuel consumption per 100 kilometers is equal to fuel consumption (liters) divided by driving distance (kilometers) multiplied by 100. The fuel consumption per 100 kilometers indicated in the manuals of domestic cars is generally the constant-speed fuel consumption. Constant-speed fuel consumption refers to the fuel economy index when the car is driving at a constant speed on a good road surface. Several key technologies related to fuel consumption include three main aspects: 1. The relationship between vehicle weight and fuel consumption is directly proportional. For every 10% reduction in vehicle weight, fuel consumption will also decrease by several percentage points; 2. Car design—if the aerodynamic drag of the car body is small, fuel consumption will significantly decrease, and the relationship between these two is also directly proportional; 3. Driving conditions are an important factor affecting fuel consumption.
