Should I shift to P or N gear when idling for a long time without turning off the engine?

Which gear is for driving forward?

Car's forward gear is the D gear. Only when the vehicle is in the forward gear can the motor vehicle move forward. Basic information about the forward gear: D (Drive) forward gear, also known as the driving gear. In this gear, the transmission will automatically switch between 1st gear and overdrive based on speed and throttle conditions. This gear is used for normal road driving. Functions of the forward gear: Generally, many vehicles have corresponding protective measures. When the vehicle is in D gear, it cannot be started. This is to prevent some drivers from accidentally operating or misfiring, causing the vehicle to suddenly lurch forward and potentially lead to safety accidents. When the vehicle is in D gear, the engine and transmission will adjust the gear based on the current vehicle speed, without requiring the driver to intervene actively. How to use the forward gear: After getting into the car, first press the brake pedal, start the engine, do not release the brake pedal yet, shift into D gear, and then release the brake pedal. After the car starts moving, you can switch between D gear, L gear, M gear, and S gear as needed. Note that shifting should be done gently; do not use excessive force, as sometimes the harder you try, the worse the shift may be.

Will changing lanes over a solid line definitely be captured by cameras?

When a vehicle changes lanes over a solid line at an intersection, it is highly likely to be captured by cameras due to their frequent shooting rate. Changing lanes over a solid line constitutes a traffic violation of disobeying prohibitory signs, punishable by a 3-point deduction and a fine. Consecutive lane changes can be determined by the vehicle's turn signals. For example, a vehicle will activate its turn signal in advance before changing lanes, indicating the intended direction of the lane change. After signaling, the driver needs to check oncoming traffic and rear vehicles before executing the lane change. Speed reduction markings are divided into longitudinal deceleration lines and transverse deceleration lines, typically installed near toll booths, exit ramps, or other areas requiring vehicles to slow down, appearing as white dashed lines. Longitudinal deceleration lines usually consist of a series of diamond-shaped dashed lines parallel to lane dividers, often placed at bridge approaches, turns, etc. Their primary function is to create a visual narrowing effect that induces a sense of pressure, prompting drivers to automatically reduce speed in designated areas. The photo enforcement system for lane changes over solid lines uses ground-pressure magnetic induction loops. Operating principle: When the front wheels pass over the induction loop on the ground, the system captures the first photo; when the rear wheels pass over the loop, it takes the second photo; when the vehicle crosses the intersection and passes over the opposite loop, the third photo is taken. This enforcement system operates 24/7, with images and related data retained for one week. Minor solid-line lane changes without major safety incidents often go undetected. Temporary license plates used on new vehicles may not be clearly captured by electronic enforcement systems due to material limitations.

What are the differences between Volkswagen Polo and Golf?

Volkswagen Polo and Golf differ in their powertrain systems, design, body dimensions, and price. The Polo measures 4053mm in length, 1740mm in width, and 1449mm in height, with a wheelbase of 2564mm. The Golf measures 4259mm in length, 1799mm in width, and 1476mm in height, with a wheelbase of 2637mm. Specific details are as follows: 1. Different powertrains: The Polo is equipped with a 1.5L naturally aspirated engine paired with a 5-speed manual or Aisin 6AT transmission, while the Golf comes with a 1.6L naturally aspirated engine or a 1.4T engine with varying power outputs. 2. Different brands: Although both are from Volkswagen, the Polo is a product of Shanghai Volkswagen, whereas the Golf is a product of FAW-Volkswagen.

What Causes a Lamborghini to Spontaneously Combust?

Automobile spontaneous combustion is usually caused by the following reasons: Do not place lighters, batteries, or reading glasses in the car: During high-temperature summer use, items such as disposable lighters, batteries, digital products, CDs, canned beverages, perfumes, and air fresheners can become 'hidden killers' in the car. Especially lighters, which contain large amounts of flammable substances like methane and butane in their fluid, can explode when heated and expanded to a certain extent, potentially causing a fire. Prolonged exposure to sunlight: Avoid parking the vehicle under direct sunlight for extended periods. Whenever possible, park in indoor parking lots or under shade to prevent prolonged exposure to sunlight.

What Causes Air Suspension to Automatically Lower After Prolonged Parking?

The reason why air suspension automatically lowers after prolonged parking is due to a sealing failure in the vehicle's air suspension system. Vehicles equipped with air suspension may experience a slight drop in ride height when parked for extended periods, but it should not lower excessively. It is recommended to first check for air leaks in the airbags and the connected pipelines. If any faults are detected, promptly visit a 4S shop for inspection, repair, or replacement. The air suspension system is the optimal solution for achieving this goal. Based on road conditions and signals from distance sensors, the vehicle's computer determines changes in the body height. Functions of the air suspension system: Vehicles equipped with adjustable air suspension feature ground distance sensors near the front and rear wheels. The vehicle's computer uses the output signals from these sensors to detect changes in body height. It then controls the air compressor and exhaust valves to automatically compress or extend the springs, thereby adjusting the chassis ground clearance. This enhances high-speed stability and improves off-road capability on rough terrains.

What is the difference between single and dual mass flywheels in Wuling Hongguang?

The differences between Wuling's dual mass flywheel (DMF) and single mass flywheel are as follows: 1. Structural difference: The DMF essentially splits the traditional solid flywheel into two parts - the primary mass (compensating for engine inertia) and the secondary mass (improving transmission inertia). These two components are connected not rigidly but through damping elastic elements (such as curved coil springs or other vibration damping components), eliminating the need for clutch plates with torsional dampers while significantly reducing engine vibration effects on vehicle propulsion. 2. Configuration advantage: Compared to conventional solid flywheel with damping clutch combinations, the DMF's larger space allows easier spring arrangement and superior damping performance, almost completely isolating engine vibrations from the transmission. This design shows particularly excellent filtering effects against unstable engine movements at low RPMs.
