What are the reasons for the failure of oil-to-gas conversion in dual-fuel vehicles?

The reasons for the failure of oil-to-gas conversion in dual-fuel vehicles are as follows: Issues with the conversion switch itself: The oil/gas conversion switch is a two-position rocker switch used to supply the conversion switch regulator with adjustment signals for using gasoline or natural gas. The logic adjustment unit in the conversion switch regulator performs the judgment and supplies corresponding adjustment signals to the gas ECU simulator, ignition timing adjuster, etc. When switching from gas to oil, if the red light is on and the yellow light flashes, it is normal; when switching from oil to gas, if the green light flashes, it is normal. Otherwise, it is abnormal, indicating that there is a problem with the conversion switch itself, mostly due to issues with the internal logic adjustment circuit. Failure of the solenoid valve at the low-pressure gas outlet of the pressure reducer: If this solenoid valve cannot be activated during the oil-to-gas conversion process, the conversion cannot be performed. Reasons for the solenoid valve's failure to activate include: damage to the solenoid valve itself; short circuit in the solenoid valve circuit; open circuit in the solenoid valve circuit, etc.

What does CDI mean in a motorcycle engine?

CDI in a motorcycle engine is the abbreviation of "Condenser-Drode-Ignite" in English, which means "Capacitor Discharge Ignition". Working principle of the CDI system: When the engine is running, the magneto also rotates to generate current. The current is rectified by a silicon diode to charge the capacitor, at which time the thyristor is in the off state and current cannot pass through the thyristor. When the pulse rotor rotates to the ignition position, the pulse generator sends an electrical signal, which is applied to the control electrode of the thyristor to trigger the thyristor to conduct. Then, the electrical energy of the capacitor enters the ignition coil through the thyristor. When the pulse rotor passes the ignition position, the pulse generator stops sending the electrical signal, and the thyristor immediately turns off, cutting off the current of the ignition coil. At this time, the ignition coil will immediately generate a self-coupled high voltage, causing the spark plug to emit a spark for ignition. This cycle repeats continuously to ensure the normal operation of the engine. Other methods of electronic ignition for motorcycles: Capacitor discharge battery ignition system (DC-CDI); Inductive discharge ignition method.

Is the 1.4T transmission of Volkswagen Tayron dry or wet?

The 1.4T transmission of Volkswagen Tayron is wet. The Volkswagen Tayron stands out in terms of exterior design and interior. Exterior design of Volkswagen Tayron: The slightly "Y"-shaped grille of the Tayron is more distinctive compared to the straightforward design of the Tiguan L. The angular rectangular LED fog lights, previously seen on the T-Roc, are also continued in the Tayron, which is expected to become a family element of FAW-Volkswagen's SUV lineup. Interior of Volkswagen Tayron: The interior design of the Tayron is quite different from that of the Tiguan L. The Tiguan L represents the early "MQB" style, with the large central display still positioned below the air vents. In contrast, the Tayron embodies Volkswagen's relatively newer design philosophy, featuring a seamlessly integrated large display and instrument panel, with the entire dashboard tilted towards the driver's side, enhancing both technological appeal and practicality. Although the two models differ significantly in interior details, Volkswagen's traditional T-shaped center console indeed lacks novelty. Fortunately, all buttons are placed in the most conventional positions, making it easy to get accustomed to.

What does the J value of a wheel hub represent?

The width of a wheel hub is indicated as 7J, 8J, etc. Here, the number represents the width of the wheel hub, while the J denotes the shape and height of the wheel hub's flange. Considerations when installing based on J value: 1. Issues during wheel hub modification: For example, if the original wheel hub is 6JX15 inches and the original tire is 195/65/15, and you come across a wheel hub with a width of 8JX17 inches, if you want to modify to this wheel hub, the standard tire should be 235/45/17. The flatter the tire, the harder it is to find. 2. During the modification process: Based on the J value, choosing which width of tire depends on what you want to achieve. Selecting a point within the range affects handling and ride quality (comfort). Choosing the midpoint balances both (but slightly compromises both). Opting for a narrower tire affects handling, while a wider tire affects comfort. 3. During wheel hub modification: The aspect ratio of the tire is also an important factor. The aspect ratio refers to the ratio of the height from the rim to the tread relative to the maximum width of the tire's cross-section, expressed as a percentage. For example, a tire with the specification 205/60R15 has a maximum cross-sectional width of 205 millimeters, an inner diameter of 15 inches, and an aspect ratio of 60.

What situations should be noted when driving a motor vehicle in a following distance?

When driving a motor vehicle in a following distance, the following situations should be noted: 1. When following a truck: The following distance should be increased, and prolonged tailgating should be avoided. If there is a large truck fully loaded with goods ahead, the following distance should be further increased because in the event of an accident involving the truck, the first vehicle to be affected is the one behind it. Prolonged tailgating should be avoided as trucks have certain blind spots, and goods on the truck may easily fall off, making the following vehicle less noticeable to others. 2. In rainy, foggy, or snowy weather: Be cautious of sudden braking by the vehicle ahead. In such adverse weather conditions, the likelihood of traffic accidents increases, and the vehicle ahead may frequently brake, so extra attention is needed. 3. When following a taxi: Be aware of sudden stops for passengers to get on or off. Special attention is required when following a taxi because taxis pick up and drop off passengers, so be prepared for stops. 4. When following a vehicle with a learner driver: Increase the following distance. Learner drivers are usually new to driving and may not be very familiar with road conditions, leading to potential incorrect operations. Therefore, maintaining a greater distance is necessary.

What is the torque for wheel bolts?

The torque for wheel bolts is generally around 100 to 120 Newton meters. However, the exact torque specifications vary depending on the brand and model of the vehicle. Always refer to the manufacturer's guidelines as the definitive standard. The direction for tightening and loosening wheel bolts is: clockwise to tighten, counterclockwise to loosen. Wheel bolts are the screws installed on the hub that connect the wheel, brake disc, and hub together. Their function is to secure these components in place. If you want to change a tire yourself, follow these steps: Retrieve the spare tire and jack. Position the jack under the vehicle frame near the tire you wish to replace, ensuring it contacts the metal part of the frame. Raise the jack until it supports the car. The jack should be positioned directly under the vehicle, and ensure it is perpendicular to the ground. Remove the hubcap. Loosen the nuts counterclockwise, but do not remove them completely—just enough to reduce resistance. Keeping the tire on the ground while initially loosening the nuts ensures that you turn the nuts, not the tire. Turn the nuts counterclockwise until they come off. Repeat this step for all lug nuts, then remove them completely. Place the new tire onto the hub. Carefully align the tire rim with the wheel bolts. Install the lug nuts and tighten them by hand until all nuts are snug. At this point, the tire replacement is complete.
