What happens if too much engine oil is added to a diesel engine?

Should You Turn Off the Engine When Waiting at a Red Light?

It is recommended not to turn off the engine when waiting at a red light, as this practice does not save fuel. Since the waiting time is relatively short, the amount of fuel injected during restart is not significantly different from the fuel consumption during a short idle period. Additionally, frequent restarts can wear out the starter motor and shorten the battery's lifespan. Additional Information: 1. Consider the duration before turning off the engine: Before turning off the engine, always consider the duration of the stop. If the parking time exceeds 2 minutes, you can turn off the engine. If the parking time is short, there is no need to do so. The engine, as the heart of the car, will see a reduced lifespan with excessive shutdowns and restarts. Frequent ignition starts can also affect the lifespan of the spark plugs. 2. Consider the duration during traffic jams: The decision to turn off the engine during traffic jams depends on the expected duration. If the idle time is expected to be long (e.g., due to traffic control), it is advisable to turn off the engine. For short-term traffic jams (such as waiting at a red light), it is not recommended to turn off the engine.

What procedures are required for the inspection of vehicle gas tanks?

Private vehicle gas cylinder annual inspections are conducted at the Special Equipment Inspection Institute under the Municipal Bureau of Quality and Technical Supervision. For the inspection, you need to bring the gas cylinder usage registration certificate from the oil-to-gas conversion, the gas cylinder factory qualification certificate, the gas cylinder installation supervision inspection certificate, the vehicle's driving license, and the owner's ID card to the Special Equipment Inspection Institute. Oil-to-gas conversion maintenance precautions: 1. Conduct a comprehensive gas leakage inspection every half month: Shake water mixed with dishwashing liquid thoroughly and apply it to the vehicle's switches, pressure reducing valves, and other joints. If bubbles are observed, it indicates a natural gas leakage issue, and the vehicle should be sent to a specialized auto repair department for inspection and repair. 2. Regularly maintain the air filter, fuel injection simulator, and pressure reducer: Improper cleaning of the air filter, incorrect adjustment of the fuel injection simulator's injection delay, or improper adjustment of the pressure reducer can cause the oil-to-gas converted vehicle to stall while driving. 3. The service life of a gas cylinder is generally 15 years: For safety reasons, relevant regulations stipulate that oil-to-gas converted vehicles must undergo an annual inspection of the gas cylinder every two years. If the gas cylinder shows wear or damage, it must be replaced before continued use.

Does the Throttle Affect Fuel Consumption?

High fuel consumption in cars is not related to the throttle. The factors that affect a car's fuel consumption are as follows: 1. Transmission: The transmission is a power-speed adjustment device connected between the engine output and the wheel drive shaft. Its basic functions are: changing the corresponding "power-speed" combination according to the car's driving needs, altering the speed direction (reverse gear), and disconnecting the engine from the drive shaft (idle). 2. Vehicle Weight: The heavier the vehicle, the more power is required, naturally leading to higher fuel consumption. 3. Design Factors: This mainly refers to the drag coefficient. Vehicle design is not just about aesthetics but also considers the drag coefficient. The more streamlined and smoother the car design, and the smaller the body attachments, the more effectively the drag can be reduced. The lower the drag coefficient, the lower the vehicle's drag, the better the stability, and the more fuel-efficient it is. Generally, a 10% reduction in drag coefficient can lower fuel consumption by 3%. 4. Tires: Tires have a direct impact on a car's fuel consumption. The wider the tread and the larger the tread pattern, the greater the friction generated, leading to increased fuel consumption.

What Causes Brake Noise in New Cars?

The reasons for brake noise in new cars are as follows: 1. Metal hard spots on brake pads: If there are tiny metal particles on the brake pads, they will produce a screeching sound when braking. You can try slamming the brakes a few times or grinding/replacing the brake pads. 2. Severely worn brake discs: After prolonged use, deep grooves may form on the brake discs at the friction points with the brake pads, causing noise during braking. If the grooves are shallow, grinding the edges of the brake pads may solve the issue. If the grooves are deep, replacing the brake discs is the only option.

How Long Does It Take to Successfully Schedule a Subject 3 Exam?

When scheduling a Subject 3 exam is under review, the approval process typically takes 5-10 days. In first-tier cities where there is a high volume of applicants, the processing time may be extended, with notifications usually sent 3-5 days before the exam at the latest. Subject 3, which includes the road driving skills test and the safety and civilized driving knowledge test, is part of the motor vehicle driver's license assessment. It is the abbreviated term for the road driving skills and safety and civilized driving knowledge test in the motor vehicle driver's exam. The content of the road driving skills test varies depending on the type of vehicle being licensed. The specific details are as follows: 1. Road Driving Skills Test Content: Generally includes: vehicle preparation, simulated lighting test, starting, driving straight, shifting gears, changing lanes, pulling over, proceeding straight through intersections, turning left at intersections, turning right at intersections, crossing pedestrian crosswalks, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and nighttime driving. 2. Safety and Civilized Driving Knowledge Test Content: Generally includes: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge.

Under what circumstances can hazard lights be used?

Here are the situations when hazard lights can be used: 1. Visibility below 100 meters: When visibility is less than 100 meters due to severe weather conditions such as heavy fog, heavy rain, or heavy snow, hazard lights should be turned on along with low beam lights and position lights to prevent traffic accidents. 2. Vehicle malfunction: If the vehicle cannot operate normally due to a malfunction or emergency and needs to stop to wait for assistance, hazard lights must be turned on. It is important to note that whenever the vehicle is stopped on the road, hazard lights should be activated. If either party involved in an accident fails to turn on hazard lights, it is considered a violation and may result in fines and penalty points. Additionally, a warning triangle should be placed behind the vehicle.
