What Does Prolonged Car Idling Mean?

What are the main reasons for difficult hot-starting of a car?

The main reasons for difficult hot-starting of a car are: 1. The more severe the fuel injector leakage, the richer the air-fuel mixture becomes, leading to difficult hot-starting; 2. Damaged carbon canister purge valve: During hot-starting, fuel atomization is normally sufficient without additional fuel vapor supply. If the carbon canister continues to supply fuel vapor to the intake tract, it will cause an overly rich mixture, resulting in difficult starting; 3. Poor fuel quality: Especially in winter when temperatures are low, the engine block temperature during cold starts is low, making fuel atomization difficult. This prevents the fuel injected into the cylinders from fully mixing with air, causing starting difficulties; 4. Damaged intake air temperature sensor; 5. Engine carbon deposits: Carbon deposits have a strong adsorption effect on gasoline. If there are excessive carbon deposits on intake valves, throttle valves, pistons, etc., they can adsorb some fuel, leading to an overly lean mixture and affecting starting performance.

Should I swipe my ID card or pull the handbrake first in Subject 2?

You need to swipe your ID card first. Here are the relevant details: 1. Definition: Subject 2, also known as the small road test, is part of the motor vehicle driver's license examination. It refers to the field driving skills test. For cars C1 and C2, the test items include five mandatory tests: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as the S-curve). Some regions also include a sixth item: high-speed toll card collection. 2. Teaching objectives: Master the basic driving operation essentials and possess the fundamental ability to control the vehicle; proficiently grasp the basic methods of field and in-field road driving, have the ability to reasonably use vehicle control components and correctly control the vehicle's spatial position, and be able to accurately control the vehicle's driving position, speed, and route.

What is a PCV valve?

Here is an introduction to the PCV valve: 1. Introduction: PCV is the abbreviation of Positive-Crankcase-Ventilation in English, which means the active ventilation control system for the crankcase (or oil pan) in Chinese. The PCV valve consists of a valve body, valve, valve cover, and spring, and cannot be disassembled. Its main function is to direct the gases inside the crankcase into the intake manifold through the PCV valve, with a small amount of air entering the intake manifold directly from the air filter via the PCV valve. This prevents icing at the throttle, incomplete combustion, and worsening emissions. It also prevents blow-by gases from entering the atmosphere and prevents engine oil from deteriorating. 2. Principle: The PCV valve is a metering control valve installed between the engine crankcase ventilation system and the intake system. The PCV valve is controlled by vacuum to regulate the flow of oil fumes from the crankcase ventilation system into the intake system. The flow rate is higher when the engine is running at high speeds compared to low speeds. Additionally, when engine backfire occurs, the PCV valve should cut off ventilation to prevent crankcase explosion.

Why is the subject 2 test scheduled 10 days later?

Relevant regulations: After completing subject 1 and obtaining the study driving certificate, candidates for the C license can schedule the subject 2 test 10 days later, while those for the A or B license must wait 20 days. According to Article 139 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" by the Ministry of Public Security: 1. Article 17: For first-time applicants or those applying to add a permitted driving type, the vehicle management office shall issue a study driving certificate within one day after passing the subject 1 test. 2. Article 40: For first-time applicants or those applying to add a permitted driving type, the following conditions must be met to schedule the subject 2 test: (1) For small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, small automatic transmission passenger cars for the disabled, wheeled self-propelled machinery, trolleybuses, and trams, the test can be scheduled 10 days after obtaining the study driving certificate.

What does it mean when the fixed point for hill start is less than 50 centimeters?

When the fixed point for hill start is less than 50 centimeters, it indicates inaccurate positioning. An error in the fixed point position less than 50 cm results in a deduction of 10 points. If the front bumper does not stop on the pole line but remains within the 1.3-meter safety zone, a deduction of 100 points is applied if the error exceeds 50 cm. Below are relevant details: 1. Introduction: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment. It refers to the field driving skill test, which for small vehicles C1 and C2 includes five mandatory test items: reversing into a garage, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-turns). 2. Stopping on a slope: This requires stopping at a fixed position on a slope with a gradient of ≥10% and a length of ≥30 meters, testing the coordination of steering, braking, and clutch operation.
