What are the main reasons for difficulty starting a hot engine?

The main reasons for difficulty starting a hot engine are as follows: 1. Fuel injector leakage. While fuel injection is normal operation, leakage constitutes additional fuel supply. The more severe the injector leakage, the richer the air-fuel mixture becomes, leading to difficulty starting when the engine is hot. 2. Damaged carbon canister purge valve. During hot starts, fuel atomization is already normal and no additional fuel vapor is needed. If the carbon canister continues to supply fuel vapor to the intake manifold, it will cause an over-rich mixture, making starting difficult. 3. Poor fuel quality. After the hot engine is shut off for a period, the engine compartment remains at high temperature. If the fuel is highly volatile, it can create excessive vapor pressure in the fuel rail. When this pressure exceeds the fuel system pressure, vapor lock occurs, causing the fuel injectors to deliver overly lean fuel vapor, resulting in starting difficulties.

What does turbine tripping mean?

Tripping involves first starting the AC (high-voltage) electric oil pump, then engaging the emergency trip device (safety device) (locally at the machine head, pull the control device handle outward by hand to engage the emergency trip device's flywheel ring), establishing safety oil pressure, and fully opening the regulating steam valve. By opening the automatic main steam valve, fresh steam can enter the turbine, initiating its rotation. Below is relevant information about steam turbines: Introduction: A steam turbine, also known as a steam turbine engine, is a rotary steam power device where high-temperature, high-pressure steam passes through fixed nozzles to form accelerated airflow, which is then directed onto blades, causing the rotor equipped with blades to rotate while performing external work. Status: Steam turbines are the main equipment in modern thermal power plants and are also used in metallurgical industries, chemical industries, and marine power systems.

What is the reason why the car door opens but cannot be locked in snowy conditions?

The main reason why a car door opens but cannot be locked in snowy conditions is usually due to the car lock cylinder freezing. Solution: If the lock cylinder is frozen, you can pour hot water into the lock cylinder to thaw it. It is best to add a little lubricating oil to the lock cylinder to prevent freezing next time. At the same time, check if there is an issue with the car lock itself. Prevention methods: To prevent the car door from freezing in winter, you can cover the vehicle with a cotton car cover after parking, which not only keeps it warm but also provides anti-theft protection. Additionally, check if there is any water or damage on the door seals and address it promptly to effectively prevent the door from freezing. If the door is frozen, avoid forcibly pulling the door or turning the key with excessive force, as this may cause mechanical damage. Instead, consider using a portable hair dryer to blow warm air into the keyhole and door seams.

What is the Principle of Traffic Violation Photography?

Traffic violation photography works as follows: When the front wheels of a vehicle pass over the induction coil on the ground, the electronic system captures the first photo. When the rear wheels pass over the induction coil, the second photo is taken. When the vehicle crosses the induction coil on the opposite side of the intersection, the third photo is captured. Violation Handling Process: After receiving the images, the command center compares the license plate information with the vehicle management database to retrieve comprehensive vehicle details such as the owner, model, color, etc. The information is then processed and uploaded to a website, allowing the violator to check the violation. Photography Coverage: Generally, one camera captures only one lane, while a few can cover two lanes. These are usually installed on the first and second lanes from the left. Digital cameras have a wider coverage, enabling them to capture all lanes in the same direction in most urban areas.
