Why Doesn't Volvo Use Longitudinal Engines?

Volvo does not use longitudinal engines because they are considered unsafe. Volvo is a Swedish brand, and Swedish laws stipulate that domestically produced cars must prioritize safety on icy and snowy roads, where front-wheel drive is deemed safer than rear-wheel drive. Since transverse engines are primarily used in front-wheel-drive vehicles, Volvo insists on using transverse engines. Transverse Engine: A transverse engine refers to an engine that is parallel to the front axle of the car. Simply put, if you stand in front of the car facing the engine and the engine is placed horizontally in front of you, it is a transverse engine. In a transverse engine, the crankshaft, transmission input/output shafts, and axle are all parallel. Therefore, for front-wheel-drive vehicles, a front transverse engine is the most suitable, as it offers a short power transmission distance and consistent direction, resulting in higher transmission efficiency. Longitudinal Engine: A longitudinal engine refers to an engine that is perpendicular to the front axle of the car. Simply put, if you stand in front of the car facing the engine and the engine is placed vertically in front of you, it is a longitudinal engine. Rear-wheel-drive vehicles generally use longitudinal engines because the power needs to be transmitted to the rear axle. When the transmission distance cannot be shortened, minimizing directional changes in power transmission becomes essential.

Is it effective to report to the police 7 days after the car was scratched?

Effective. Scratches also belong to traffic accidents and can be reported to the police at any time. Methods for handling vehicle scratches: After accidentally scratching another vehicle, immediately choose a suitable location to stop the car. Tighten the handbrake, cut off the power, and turn off the engine. At night, turn on the width lights and taillights. On highways, set up a danger warning sign behind the car. Check the safety conditions of both parties. If there are casualties, injuries, or personal safety is compromised, report to the police immediately. Record the vehicle and owner information of both parties, including license plate numbers, driver's licenses, vehicle registration certificates, and insurance certificates. Carefully inspect the vehicle's condition and use digital cameras or mobile phones to document the scratched areas and overall vehicle condition. Visit the insurance claims service center for vehicle damage assessment and keep the repair invoices during the subsequent repair process. Liability determination: Failure to maintain a safe distance and rear-ending the vehicle in front makes the following vehicle responsible. Changing lanes and affecting normally moving vehicles makes the lane-changing party responsible. At intersections controlled by traffic signals, if a turning vehicle does not yield to a straight-moving vehicle, the turning vehicle is responsible. At intersections without traffic signals, failure to yield to vehicles coming from the right makes the non-yielding party responsible, etc.

What Causes the Engine Warning Light to Illuminate in Hyundai Vehicles?

The engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: This includes sensors such as coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen sensors. When these sensors are damaged, have poor connections, or experience signal interruptions, the vehicle's ECU cannot accurately obtain engine data, triggering the warning light. Fuel/oil quality issues: Failure to use fuel and engine oil as specified by the manufacturer may cause engine wear, leading to the warning light activation. Poor fuel mixture combustion: This can result in engine carbon buildup or knocking. When detected by oxygen sensors and reported to the ECU, the warning light activates. Potential causes include spark plug failure, ignition coil issues, fuel pump malfunction, or clogged fuel lines. Turbocharging problems: Issues with intake boost pipes or turbochargers (most commonly turbocharger damage) can trigger the light. Symptoms may include oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black exhaust smoke. Intake system issues: Air intake problems may cause engine pipe blockages, potentially triggering the warning light. A dirty air filter that hasn't been regularly cleaned can lead to intake issues. Exhaust system problems: Exhaust faults (often involving the catalytic converter) can activate the warning light. Common causes include rear oxygen sensor failure, catalytic converter issues, or exhaust camshaft/bearing problems. Using leaded gasoline, improper lubricant additives, physical damage to the converter, or fuel system malfunctions may damage the catalytic converter. Anti-theft system malfunction: If the vehicle's electronic anti-theft system fails or doesn't match the engine ECU, it may prevent normal engine operation and trigger the warning light. When the engine warning light illuminates, follow these steps: First check if the engine operates normally. If there's shaking, black smoke, etc. (especially with a red warning light), do not restart the engine. If the engine starts normally, turn it off for 5-10 minutes. Then without pressing the brake (or clutch), activate the ignition to ON position for 5-10 seconds to observe if the warning light disappears after system self-check. If the light remains on, visit a service center promptly. Technicians can use diagnostic tools to read trouble codes and perform targeted repairs.

Why is the Practice for Subject 3 Limited to Only 3 Days?

There is no regulation that restricts the practice for Subject 3 to only 3 days; it should be based on your actual situation. The amount of time spent practicing for Subject 3 does not directly correlate with the test results, meaning more practice does not guarantee a pass. Content of Subject 3: The road driving skills test for Subject 3 generally includes: vehicle preparation, simulated lighting test, starting, driving straight, gear shifting operations, lane changing, pulling over, going straight through intersections, left turns at intersections, right turns at intersections, crossing pedestrian crossings, passing school zones, passing bus stops, meeting other vehicles, overtaking, making U-turns, and night driving. Important Notes for Subject 3: In the 100-meter gear shifting test of Subject 3, the requirements for speed and gear selection are very strict. Generally, first gear is used for speeds between 10--20 km/h, second gear for 20--30 km/h, third gear for 30--40 km/h, fourth gear for 40--50 km/h, and fifth gear for speeds above 50 km/h. Using a low gear at high speeds or a high gear at low speeds can cause severe shaking of the vehicle, and the computer system will automatically deem the test as failed.

Can I Bring My Own Photo for the License After Passing Subject Four?

Generally, you cannot bring your own photo for the license after passing Subject Four, but the specific process may vary depending on the local driving test procedures. After passing Subject Four, some vehicle management offices will use the portrait information collected during registration to produce the license, while others will collect portrait information on-site after passing Subject Four or allow you to bring your own photo for the license. Nowadays, most vehicle management offices adopt the first method. After the Subject Four results are uploaded, the system will directly use the photo taken during driving school registration to produce the license, so you cannot bring your own photo. However, if you want to change the photo, you need to communicate with the driving school in advance and have them collect your portrait information again. Once the new photo is uploaded to the system, the updated photo will be used for the license. Otherwise, you will have to communicate with the staff at the test center to see if they can use the photo you brought for the license. Requirements for driver's license photos: The background color should be white, and you should not wear uniforms. The portrait should be clear, with rich layers, natural expression, and no obvious distortion. The photo size should be 32mm x 22mm, with a head width of 14mm to 16mm and a head length of 19mm to 22mm. The photo can be pasted or digitally printed. The photo should be taken at the vehicle management office or a licensed photo studio. Both men and women should not wear earrings, and those who need vision correction should wear glasses. Women should not have their hair loose, and men should not have excessively long hair. The head should occupy about two-thirds of the photo. Applicants applying for a motor vehicle driver's license or temporary motor vehicle driving permit must provide a front-facing, bareheaded, color half-body ID photo taken within the last six months.
