How to Check Fuel Tank Capacity?

What is the reason for the abnormal data flow in the EA888 timing group 93?

It may be that when the Volkswagen EA888 engine starts, it is accompanied by abnormal vibrations, noises, etc. The noise will disappear after the water temperature rises, but in severe cases, the engine may fail to start. Continued attempts to start may cause the timing chain to skip teeth, leading to the valves being hit by the pistons. It is recommended to take the vehicle to a repair shop for inspection. More extended information is as follows: 1. Volkswagen EA888 engine: This is a newly designed engine by Volkswagen, integrating advanced technologies such as direct fuel injection, turbocharging, and variable valve timing, achieving a balance between power and economic environmental protection. The EA888 engine adopts intake variable valve timing technology, which can effectively improve intake and exhaust efficiency. This is mainly achieved through a vane-type hydraulic adjuster located on the intake camshaft. The vane-type adjuster consists of an outer shell, an inner vane rotor, and a locking pin inside the vane rotor. The outer shell is fixed to the external timing gear and is driven by the crankshaft. The inner vane is directly fixed to the intake camshaft and rotates with it. 2. Working principle: It mainly controls the hydraulic oil in the corresponding pipeline through the camshaft adjustment valve to drive the vane in the adjuster, thereby rotating the camshaft to advance or delay the opening and closing of the valves, with an adjustable range of up to 60° of crankshaft angle.

How much overweight in curb weight will fail the annual inspection?

According to regulations, all trucks are inspected for curb weight, and those failing to meet the standard cannot pass the annual inspection. For blue license plate trucks, the total weight of the vehicle and cargo must not exceed 4.5 tons. Below are the requirements for annual inspection documents and time: Annual inspection documents: Original "Motor Vehicle License and Certificate Application Form" (signed by the entrusted person for company vehicles, or by the owner for private vehicles), proof of compulsory traffic accident liability insurance for motor vehicles, copy of the tax payment or tax exemption certificate for vehicle and vessel tax, original certificate of motor vehicle safety technical inspection, and original "Motor Vehicle Driving License". Annual inspection time requirements: The annual inspection time for vehicles is determined by the initial registration date of the new vehicle. For example, if the initial registration date on the motor vehicle driving license is June 2015, then the annual inspection time is every June. Additionally, according to Article 40 of the newly revised "Motor Vehicle Registration Regulations", the owner of the motor vehicle may apply for the inspection compliance mark at the vehicle management office of the registration location within three months before the expiration of the motor vehicle inspection validity period. This means that vehicles due for inspection in June can undergo the annual inspection in April, May, or June.

Does the sixth-year vehicle inspection require an on-site test? What procedures are needed?

Procedures required for the sixth-year vehicle inspection are as follows: Vehicle Annual Inspection Form: Collect the vehicle annual inspection form at the service hall, fill it out as required, and attach the traced chassis number and engine number. The vehicle owner should sign their name in the designated section. Drive the vehicle to the external inspection window, park it in order, prepare the inspection form and vehicle license, and wait for the external inspection. Annual Inspection Time Regulations: The vehicle inspection time is determined based on the date of the new vehicle registration. For example, if the initial registration date on the motor vehicle license is June 2015, then the vehicle inspection time is every June. Additionally, according to Article 40 of the newly revised "Motor Vehicle Registration Regulations," the owner of the motor vehicle can apply for the inspection compliance mark at the vehicle management office of the registration location within three months before the expiration of the motor vehicle inspection validity period. This means that vehicles due for inspection in June can undergo the annual inspection at the testing station in April, May, or June.

What is the PWR function?

Automotive PWR is the power mode button, and the indicator light will illuminate when this button is pressed. The function of the automotive PWR button: The automotive PWR button is a setting for the electronic throttle. After pressing it, the throttle response becomes faster, delaying the upshift timing to achieve peak torque. During driving, pressing the accelerator deeply may even cause multiple downshifts. PWR means that in power mode, the ECTPWR light on the dashboard illuminates, the transmission shifts into higher gears at higher vehicle speeds, and shifts into lower gears more sensitively than in normal mode. How to use the automotive PWR: Simply press the button lightly, and the car's engine will start. Pressing the button again will turn on the car's main power supply, restoring the car to its normal working state.

What is the firing order?

The firing order of the engine is 1, 3, 4, 2. This means when cylinder 1 is in the power stroke, cylinder 3 is in the compression stroke, cylinder 4 is in the intake stroke, and cylinder 2 is in the exhaust stroke. Factors affecting the firing order: The firing order depends on factors such as the engine's structure, crankshaft design, and crankshaft load. The crankshaft is mentioned twice here because the engine's smoothness largely depends on the crankshaft. The centrifugal inertial force generated by the uneven rotating mass of the crankshaft can cause engine vibration. Crankshaft symmetry and uniformity: To ensure smooth operation, cylinders that fire consecutively should be spaced as far apart as possible. In V-type engines, the left and right cylinder banks should alternate firing. Therefore, the engine must have a firing order that balances the crankshaft's operation.

Is it illegal to make a U-turn in a left-turn lane?

It is not illegal for a motor vehicle to make a U-turn in a left-turn lane if there is no no U-turn sign. Legal basis: Article 49 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China states that motor vehicles may make U-turns at locations where there are no no U-turn or no left-turn signs or markings. Locations where U-turns are allowed: In the absence of a dedicated U-turn traffic light or other traffic signs regulating U-turns, motor vehicles may make U-turns during traffic light cycles; if there are traffic signs explicitly indicating U-turns during red or green lights, U-turns should be made during the specified signal period. When making a U-turn, it must not interfere with the normal passage of other vehicles or pedestrians.
