Can Diesel Fuel Injectors Be Repaired?

Some faults in diesel fuel injectors can be repaired, such as injector dripping, poor sealing between the injector needle valve and valve body, seizure, clogging, etc. For other faults, it is recommended to contact the manufacturer's after-sales service or professionals for handling. For issues like injector dripping, poor sealing between the injector needle valve and valve body, seizure, or clogging, the injector should first be disassembled and the needle valve and valve body cleaned with clean diesel. If there are minor pitting and indentations on the sealing cone surface of the needle valve and valve body, they should be ground on specialized equipment or with wire-cutting pliers (note: grinding paste must not enter the sliding surface between the needle valve and valve body). Then, use engine oil for further grinding until the pitting and indentations on the sealing cone surface disappear and it appears black and shiny. For injectors with seized needle valves and valve bodies, first use wire-cutting pliers to remove the needle valve, then clean it thoroughly in clean diesel. Next, use a fine oilstone or sand strip to smooth out the raised areas caused by the seizure (note: do not damage other parts), ensuring the needle valve slides smoothly within the valve body. Then, use grinding paste and engine oil to grind the sealing cone surface to meet the aforementioned requirements. If there are numerous deep pits and indentations on the sealing cone surface of the needle valve and valve body that cannot be repaired, the injector should be replaced with a new one. The injection pressure and fuel atomization quality should then be adjusted on a test bench or in the vehicle to meet operational requirements.

What is the bulb model of the Venucia T60?

The bulb model of the Venucia T60 is H4. The car's headlights use LED light sources, and the lamp assembly design is relatively conventional, with LED daytime running lights positioned below, featuring excellent light concentration and an independent vertical layout. The primary function of car bulbs is to ensure driving safety at night, making it essential to choose high-quality bulbs. Bulbs require regular replacement as their brightness gradually diminishes with vehicle usage. Typically, bulbs should be replaced every 20,000 kilometers, and the engine should be turned off for 5 minutes before replacement. The Venucia T60 has body dimensions of 4412mm in length, 1820mm in width, and 1679mm in height, with a wheelbase of 2640mm.

What Causes Engine Idle Vibration After Water Rinse?

Because a small amount of water entered the high-voltage line during car washing, and the engine air filter element got wet, leading to increased intake resistance and water entering the combustion chamber, resulting in poor ignition system performance. Here are the related explanations: 1. Ignition system issues: Check the working condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or inadequate spark plug firing can also cause such fault symptoms. 3. Unstable oil pressure: It is recommended to go to a professional repair shop to check whether the fuel supply pressure and intake pressure sensor are normal. If the fuel pump supply pressure is abnormal or the intake pressure sensor values are incorrect and not working properly, it can cause body vibration.

What is the reason for the car body brushing the line during parallel parking exit?

The reason for the car body brushing the line during parallel parking exit is that the steering wheel is turned too late, causing the car body to get too close to the sideline and resulting in brushing the line. The correct method for parallel parking exit: After hearing the voice prompt, press the clutch and brake, shift to first gear, turn on the left turn signal, turn the steering wheel fully, and slowly exit the parking space. When the right front corner of the engine hood touches the right roadside line (this is the first point), straighten the steering wheel and continue moving forward. When one-third of the left side of the engine hood aligns with the yellow line (this is the second point), turn the steering wheel one full turn to the right; let the car go around the corner of the parking space and exit. When the car body is parallel to the road, straighten the steering wheel to the left and exit the parallel parking test area. Precautions for parallel parking exit: During the parallel parking exit process, pay attention to controlling the clutch; the speed should be slow, but you must not stop midway. The timing of turning the steering wheel must be accurate; otherwise, missing the timing can easily lead to brushing the line. Be sure to slow down, stabilize the clutch, and maintain a steady speed. When reversing into the parking space, the first full turn to the right should be done only after the left corner of the parking space disappears from the right rearview mirror; otherwise, the front wheels may brush the line during reversing or exiting. Note the penalty points for parallel parking exit: brushing the corner during exit deducts 10 points; the tires touching the lane sideline deducts 10 points; stopping midway results in disqualification.
