Where is the automatic headlight sensor located?

Do I need to restart the inspection if I only completed half of the vehicle inspection and plan to continue it after a few days?

You need to restart the inspection. Introduction to Vehicle Annual Inspection: Vehicle annual inspection (Vehicles inspection), also known as motor vehicle inspection. The inspection items and scope vary depending on the usage nature of the motor vehicle. According to the definition in RB/T218-2017 "Requirements for the Qualification and Assessment of Inspection Bodies - Motor Vehicle Inspection Institutions", motor vehicle inspection includes three categories: motor vehicle safety technical inspection, motor vehicle emission inspection, and comprehensive vehicle performance inspection. Consequences of Not Undergoing Annual Inspection: If a vehicle is found by traffic police on the road without an annual inspection, the owner will be fined or the vehicle will be impounded. At the same time, in insurance contracts, vehicles that have not undergone timely annual inspections are considered unqualified, and no claims will be paid in the event of a car insurance accident.

Will crossing the line at night be captured?

Crossing the line at night will be captured. As long as there are electronic surveillance cameras, driving over the line at any time will result in being photographed and fined. Detour to avoid emergencies: If an accident or natural disaster affects the road ahead, making it impassable for an extended period and forcing vehicles behind to detour by crossing the line, this will not be treated as a traffic violation. Follow the instructions of traffic police: According to the Road Traffic Safety Law, when traffic signals are malfunctioning and there are traffic police directing on-site, drivers should follow the instructions of the traffic police. Special vehicles performing tasks: If traffic violations such as running a red light or crossing solid lines occur while yielding to special vehicles like fire trucks or ambulances, these actions will not be considered violations. If a penalty notice is issued due to being captured by electronic surveillance, an administrative reconsideration can be requested to revoke the penalty.

What is the power of the Caterpillar 320d engine?

The power of the Caterpillar 320d engine is 103 kW/2000 horsepower. Engine power: The maximum output power of the engine is 177 kW/241 horsepower, 246 kW/335 horsepower, and 309 kW/420 horsepower respectively. When choosing which engine to equip in this new sedan, the exceptional comfort and power of the Phaeton, as well as the technical potential of the Volkswagen brand, were fully demonstrated. The engines used in the production models are: 3.2-liter V6 engine, output power 177 kW/241 horsepower, maximum torque 315 Nm, equipped with a Tiptronic six-speed manual/automatic transmission; 4.2-liter V8 engine, output power 246 kW/335 horsepower, maximum torque 430 Nm, equipped with a Tiptronic six-speed manual/automatic transmission; the top-level model features a 6-liter W12 engine, output power 309 kW/420 horsepower, maximum torque 550 Nm, equipped with a Tiptronic five-speed manual/automatic transmission.

Is it normal to have clearance between the upper and lower parts of the crankshaft?

If the clearance is reasonable, it is normal. Otherwise, the high temperature during operation may cause the crankshaft to expand and seize. However, excessive clearance is not acceptable as it will generate significant noise. Introduction to Crankshaft: The crankshaft is the most critical component in an engine. It receives the force transmitted by the connecting rod and converts it into torque, which is then output through the crankshaft to drive other engine accessories. The crankshaft is subjected to the combined effects of centrifugal force from rotating masses, periodically varying gas inertia forces, and reciprocating inertia forces, resulting in bending and torsional loads. Therefore, the crankshaft must have sufficient strength and stiffness, with wear-resistant journal surfaces, uniform operation, and good balance. Crankshaft Structure: To reduce the mass of the crankshaft and the centrifugal force generated during operation, the crankshaft journals are often hollow. Oil holes are drilled on each journal surface to allow the introduction or discharge of oil for lubricating the journal surfaces. To minimize stress concentration, transition arcs are used at the connections between the main journals, crankpins, and crank arms.

Where is the car air conditioning expansion valve located?

Small car air conditioning expansion valves are generally located at the condenser inlet. Below is relevant information about the air conditioning expansion valve: 1. Thermal expansion valve: Also known as a throttle valve, the thermal expansion valve is one of the four major components in a car air conditioning refrigeration system (evaporator, compressor, condenser, and expansion valve). It senses the superheat of refrigerant vapor at the evaporator outlet to adjust the opening degree of the expansion valve, thereby controlling the flow of liquid refrigerant entering the evaporator. 2. Classification: Thermal expansion valves are divided into internally equalized and externally equalized types based on their balancing method: The working principles of internally equalized and externally equalized expansion valves are basically the same, with the difference being that the diaphragm of an internally equalized valve senses the evaporator inlet pressure. When the pressure drop in the evaporator is too large, it reduces the superheat sensed by the power head, causing insufficient valve opening. In contrast, the diaphragm of an externally equalized valve senses the evaporator outlet pressure, avoiding the influence of evaporator pressure drop on valve opening and overcoming the shortcomings of internally equalized valves.

Why don't new cars need to go to the DMV for annual inspection?

Because it can be done online. You can apply online by logging into the DMV website and submitting the relevant materials. Annual inspection regulations: In 2021, the DMV's new regulations state that starting from September 1st, the annual inspection process has been readjusted, and it will no longer be necessary to visit the DMV to collect the inspection certificate. The new regulations indicate that new cars within six years do not require an annual inspection, nor do they need to visit the DMV to collect the inspection certificate. The DMV states that as long as you log into the DMV website, complete the information according to your details, and follow the steps for review to obtain the inspection certificate, the relevant department will mail the required materials or the inspection certificate to the address specified by the vehicle owner. Applicable scope: This only applies to new car owners who need to obtain an inspection certificate from the DMV within six years. However, owners of cars older than six years still need to undergo annual inspections.
