What is the definition of candle-type suspension?

Candle-type suspension is a component that enhances the steering control stability and driving stability of a vehicle. Below are specific details about candle-type suspension: 1. The advantages of candle-type suspension are: When the suspension system deforms, the positioning angle of the kingpin does not change, only the wheelbase and axle distance slightly vary, which is particularly beneficial for the steering control stability and driving stability of the vehicle. 2. For the steering wheels, during suspension deformation, the positioning angle of the kingpin remains unchanged, with only slight changes in the wheelbase and axle distance, thus improving steering control and driving stability. However, the lateral forces are entirely borne by the long sleeve 3 on the kingpin 5 and the kingpin itself, resulting in high friction resistance between the sleeve and the kingpin, leading to severe wear.

What is the Difference Between 92 and 95 Octane Gasoline?

The differences between 92 and 95 octane gasoline are as follows: 1. Different compositions: 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. 2. Different anti-knock properties: 95 octane gasoline has better anti-knock performance than 92 octane gasoline. 3. Different applicable engine types: 95 octane gasoline is suitable for engines with high compression ratios, while 92 octane gasoline is suitable for engines with low compression ratios. Additional information: The introduction to gasoline octane ratings is as follows: 1. Meaning of gasoline octane rating: It is the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the octane rating, the stronger the anti-knock performance. 2. Composition of gasoline: Standard gasoline consists of isooctane and n-heptane. Higher octane ratings are not necessarily better; the appropriate gasoline octane rating should be selected based on the engine's compression ratio. Isooctane has good anti-knock properties, and its octane value is set at 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, so its octane value is set at 0. If the gasoline has an octane rating of 90, it means that the gasoline has the same anti-knock performance as standard gasoline containing 90% isooctane and 10% n-heptane.

What Are the Reasons for Engine Oil Entering the Car Engine Radiator?

The following are the reasons for engine oil entering the car engine radiator: 1. Cylinder liner damage: If there is engine oil in the radiator, it may be due to cracks in the cylinder liner. Under high pressure, the engine oil can seep directly into the car radiator through these gaps. 2. Radiator damage: Damage to the engine oil radiator or transmission radiator can also cause engine oil to mix into the radiator. 3. Cylinder head gasket damage: If there is engine oil in the radiator and the high-temperature warning light is on, it is likely due to a damaged cylinder head gasket. The following are solutions for engine oil entering the car engine radiator: 1. For cylinder liner damage, the solution is to replace or repair the cylinder liner. 2. For radiator damage, the solution is to replace the radiator. 3. For cylinder head gasket damage, the solution is to replace the cylinder head gasket.

How Deep Should the Brake Be Pressed When Starting an Automatic Transmission Car?

When starting an automatic transmission car, gently press the brake pedal. Below is the sequence for starting an automatic transmission car: 1. Insert the key and turn it to the second position (power-on mode), then wait for the system self-check to complete. 2. Shift the gear lever from P (Park) to N (Neutral). 3. Release the brake and start the engine. 4. Press the brake pedal with your foot, shift the gear lever from N to D (Drive), release the brake, and press the accelerator to start moving. Here are some additional tips for driving an automatic transmission car: 1. Accelerate gently when starting; always start in P or N gear, and avoid coasting in neutral. 2. Shift to N gear when waiting at a red light or briefly stopping; use P gear when parking. 3. Never shift into P gear while the car is moving. 4. Ensure the car is completely stopped before shifting into R (Reverse) for backing up.

What to Pay Attention to in Driving License Subject 3

Here are the precautions for the Subject 3 test: 1. The clutch can only be used when starting, shifting up, shifting down, or stopping. Do not press the clutch during normal driving. When encountering a situation that requires slight deceleration, only use the brake to avoid coasting. 2. The green light will flash several times before turning red. At this time, based on the distance to the intersection and the vehicle speed, press the accelerator if the distance is close and the speed has not decreased. 3. After completing the Subject 3 road test, when the examiner gives the command "pull over," stop decisively as long as it is not at an intersection or on a solid line. 4. Upon hearing the command, assess the road conditions. If there are no solid lines or you are too close to the intersection, quickly turn on the right signal, check the rearview mirror, brake to decelerate and merge, position the car slightly to the right of the road center, turn the steering wheel back to the left, and press the clutch when the car can coast to straighten out. Once the car is straight, turn the wheel to the right to park.

How Long Does It Take to Practice for Driving License Test Subject 3?

Subject 3, also known as the road test, generally takes about one week of practice to master all the essential maneuvers. Below is an introduction to Subject 3: 1. Subject 3 includes the road driving skills test and the safety and civilized driving knowledge test; 2. Subject 3 is part of the motor vehicle driver's license assessment and is the abbreviated term for the road driving skills and safety and civilized driving knowledge test in the motor vehicle driver's examination; 3. The content of the road driving skills test varies depending on the type of vehicle being licensed. Below is extended information on key techniques for Subject 3: 1. Gear shifting operation: Ensure sufficient throttle input, and after each gear shift, decisively proceed to the next shift action; the shifting action, including hand and foot movements, should be quick, accurate, and smooth; 2. Straight-line driving: The key to straight-line driving lies in identifying reference points to determine if the vehicle is veering off course. Reference points can include the dashed white lines on either side of the lane, curbs, streetlight poles, etc.; additionally, keep your gaze far ahead and avoid focusing solely on the hood position; if the vehicle starts to veer, make slight adjustments to the steering wheel promptly without turning it excessively; 3. Pulling over: Pulling over requires the vehicle to be within 30 centimeters of the roadside line. The principle is similar to straight-line driving—identify a reference point. Generally, when the raised part of the windshield wiper aligns with the roadside line, the distance is approximately 30 centimeters.
