Where are the reference points for a right-angle turn?

Reference points for a right-angle turn: The point where the right side of the vehicle is 30 centimeters away from the edge line. Below is relevant information about right-angle turns: 1. Overview: The right-angle turn is an assessment point in Subject 2 of the driver's license test, evaluating the driver's ability to correctly operate the steering and accurately judge the vehicle's inner and outer wheel differentials when driving through sharp turns. 2. Deduction points: Running over the protruding point results in failure; each time the wheels run over the road edge line, 20 points are deducted; completing the maneuver by reversing results in a 10-point deduction; failing to use or incorrectly using turn signals results in a 10-point deduction.

How Severe Does a Crash Need to Be to Damage the Radiator?

Damaging the car radiator constitutes a major accident, typically involving severe damage to the front end of the vehicle. Below is an introduction to the car radiator: 1. Main Components: The radiator is part of the car's cooling system. In an engine's water cooling system, the radiator consists of three parts: the inlet tank, outlet tank, header, and radiator core. 2. Primary Function: When the engine's water temperature is high, the water pump circulates water repeatedly to lower the engine's temperature, thereby protecting it. In winter, if the water temperature is too low, the water circulation stops to prevent the engine from becoming too cold.

Why does an automatic transmission maintain high RPM without shifting up?

This is a computer-programmed feature (overtaking mode). When the driver accelerates aggressively, the computer interprets it as the vehicle needing to overtake or requiring more power. Since higher gears provide less torque, the computer maintains the current gear or downshifts to enhance performance. Here's an introduction to automatic transmissions: 1. Classification: As the name suggests, an automatic transmission doesn't require manual gear shifting by the driver. The vehicle automatically selects the appropriate gear based on speed and driving conditions. 2. Operation: Driving an automatic transmission vehicle primarily involves using Park (P), Reverse (R), Neutral (N), and Drive (D) gears to meet general driving needs. For specific driving conditions, other functional gears may be required.

Are There Hydrogen-Powered Vehicles in China?

Currently, there are no hydrogen-powered vehicles in China. Here is some information about hydrogen-powered vehicles: 1. Advantages: Hydrogen energy has the benefits of abundant reserves, high efficiency, no greenhouse gas emissions, ease of storage and transportation, and high safety, making it considered the ultimate solution for future energy replacement. 2. Reasons for the absence of hydrogen-powered vehicles in China: China has a vast territory, and building hydrogen refueling stations extensively, like in Japan, is extremely difficult and costly. It is foreseeable that before breakthroughs in controlled nuclear fusion technology, hydrogen production as an energy source will remain a less economical choice, and relying on hydrogen to replace fossil fuels is unrealistic.

How Often Should Brake Fluid Be Changed in an Automatic Transmission Car?

Generally, brake fluid should be replaced every 2 years or every 40,000 kilometers driven, but the specific interval should be determined by the cycle specified in the car's user manual. Below is some information about brake fluid: 1. Introduction: Brake fluid, also known as hydraulic brake fluid or braking fluid, is a type of hydraulic fluid used in hydraulic brake systems. It is made from refined diesel distillate with thickeners and antioxidants added. There are three types of brake fluid: mineral oil brake fluid, alcohol-based brake fluid, and synthetic brake fluid. 2. Precautions: Do not mix different types or brands of brake fluid. Due to differences in formulations, mixing brake fluids can lead to a decline in the performance indicators of the brake fluid.

What gear should be engaged when parking on a downhill slope?

When parking on a downhill slope, engage neutral gear and firmly apply the handbrake. Alternatively, you can shift into first gear and firmly apply the handbrake to prevent the car from rolling. For automatic transmission vehicles, first firmly apply the handbrake and then shift into P (Park) gear. Automatic transmission vehicles have P (Park) and N (Neutral) gears, both of which can be used when parking. The P (Park) gear is used when parking and turning off the engine, while the N (Neutral) gear is used for short-term parking without turning off the engine. When P (Park) gear is engaged, the locking mechanism locks the transmission gears, effectively locking the wheels indirectly. Even without applying the handbrake, the car will not move. The N (Neutral) gear does not have a locking mechanism, so if the handbrake is not applied after shifting into N (Neutral), the car may roll.
