Can a car be started in P gear?

What is the engine RPM at 120 km/h?

Vehicle speed, engine RPM, and gear position are interrelated. Under normal conditions, at a speed of 120 km/h on level ground, most vehicles' engine RPM should be between 2500-3000. Below is more information about RPM: RPM for small-displacement vehicles: Generally, small-displacement manual transmission vehicles at 120 km/h will have an RPM of 4200-4500. For engines above 1.5 liters, the RPM is typically around 3300, while 6-speed automatic transmissions usually maintain around 2200 RPM at 120 km/h. RPM details: Under normal driving conditions, the engine RPM in top gear is as follows: when reaching 100 km/h, the RPM is generally around 2800; when reaching 110 km/h, the RPM is typically about 3200.

Is it penalized to steer with one hand in Subject 2?

Steering with one hand in Subject 2 is not penalized. Here are the relevant details: Slow reaction: Steering with one hand can make it difficult to track how much the wheel has been turned, especially during reverse parking. Additionally, if the steering is heavy, one hand might not be sufficient, leading to delays and potential wheel crossing the line. Subject 2, also known as the small road test: It is part of the motor vehicle driver's license examination and refers to the field driving skills test. For small vehicles (C1/C2), the test items include reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-turns) as the five mandatory items (some regions include a sixth item, highway toll card collection).

Can a C4 driver's license drive a four-wheel low-speed electric vehicle?

C4D driver's license can drive electric four-wheel vehicles. The definition of a driver's license is: A motor vehicle driver's license is a legal document issued by the administrative authorities after a person who is legally allowed to learn to drive a motor vehicle has studied, mastered the knowledge of traffic regulations and driving skills, and passed the examination, permitting them to drive a certain type of motor vehicle. Examination content: The revised "Content and Methods of Motor Vehicle Driver Examination" (GA1026) was implemented on October 1, emphasizing the assessment of safe and civilized driving, recognition of typical illegal behaviors, etc. Many examination items have added time limits, and there are also more driving operations that are directly judged as unqualified.

What is the normal tire pressure for a regular sedan?

Generally, the normal tire pressure ranges between 2.3-2.5. If the car is fully loaded (5 people), it is more suitable to adjust the tire pressure to around 2.5; for two people, a tire pressure of 2.3 is also normal. The following are the effects of excessively high or low tire pressure: Excessively high tire pressure: When the tire pressure is too high, it reduces the tire's grip, affects braking performance, and the driver may feel vibrations in the steering wheel. In severe cases, it can even cause the car to veer off course, reducing driving comfort. Because excessively high tire pressure decreases the contact area between the tire and the ground, it increases localized wear on the tire tread and reduces the tire's lifespan. Excessively low tire pressure: When the tire pressure is too low, it increases the contact area between the tire and the ground, raising the friction coefficient between the tire and the ground. This increases driving resistance, accelerates tire wear, and reduces the tire's lifespan.

Is it necessary to repair minor scratches on the wheel hub?

When the damage to the wheel hub accumulates to a certain extent, it is essential to promptly take it to a professional repair shop for maintenance. Tire Sidewall: The tire sidewall is the weakest and thinnest part of the tire. When encountering minor bumps on the road, the sidewall deforms to absorb some of the impact. Continuing to use a tire with scratches on the sidewall poses a risk of a blowout, which is very dangerous. It is recommended to replace the tire. Repair: Some repair shops use body filler (bondo) to fill in the damaged areas, sand it down, and then repaint. However, since the wheel hub operates at high speeds and experiences significant temperature fluctuations, the body filler on the hub is prone to expansion and detachment, leading to paint damage and rendering the wheel hub repair ineffective.

What is the solution for Honda Fit idle vibration?

Reasons and solutions for Honda Fit engine vibration at idle: 1. Dirty air filter: The air filter is designed to protect the engine and reduce wear. It should generally be replaced every 10,000 kilometers. If not replaced in time, insufficient air intake can cause low idle speed and engine vibration. Simply replacing the filter element can solve this problem. 2. Broken high-voltage wire: A broken high-voltage wire refers to a break in the wire core, which can affect ignition and cause engine vibration. Use a multimeter to measure the resistance and replace the one with significantly higher resistance. 3. Spark plug lifespan: After 30,000 to 40,000 kilometers, the ignition efficiency of spark plugs significantly decreases, which can affect ignition. This is the most common issue, and replacing all spark plugs can resolve it. 4. Low idle speed: The engine idle speed value is set in the computer. When the speed drops below a certain range, the car's computer will automatically adjust it. Low coolant temperature can also cause low idle speed. Check and replace the thermostat if necessary. 5. Abnormal coolant temperature: The engine operating temperature has a normal range. High coolant temperature can cause early ignition timing, changes in the air-fuel mixture, thinning of engine oil viscosity, and reduced lubrication performance. Common causes include lack of antifreeze, a stuck thermostat, non-functioning fan, or inaccurate temperature control switch. Eliminating these faults can resolve the vibration. 6. Clogged fuel injector: The fuel injector in an electronic fuel injection car is a key component for fuel injection and has a long lifespan, reaching hundreds of thousands of kilometers. However, gum in gasoline can clog the injector nozzles, causing inconsistent fuel injection among injectors and uneven cylinder operation, leading to engine vibration. The solution is to remove and clean them. 7. Carbon deposits and oil sludge clogging: Over time, carbon deposits and oil sludge can clog the throttle body, idle valve, and intake ports, causing poor air intake and affecting idle stability, leading to vibration. Inspect and clean these parts with a cleaning agent without needing to remove them.
