Why Does Fuel Consumption Increase After Changing the Fuel Injector?

What items are included in the first maintenance of the Vezel?

The first maintenance at a 4S shop includes the following aspects: changing the engine oil and oil filter, cleaning the air filter; checking the levels of various fluids to ensure they are normal, inspecting the generator belt and wiper blades for damage; checking tire pressure for normalcy and examining tires for uneven wear, bulges, or damage; inspecting the chassis, including brake pads, brake discs, connecting rods, ball joints, CV joints, and checking for scratches, etc.; examining all switches in the vehicle; ensuring all lights are functioning properly. Estimated time: Completing all tasks takes about 2 hours. Items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; vehicle purchase invoice. Take these to the designated first maintenance facility for the vehicle's first service. Note: Make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after a new car has been driven, with specific timing varying by vehicle, typically after driving 1,000 to 3,000 kilometers. It's essential to attend the first maintenance promptly, neither early nor delayed. The completion of the first maintenance marks the end of the vehicle's break-in period, allowing it to be driven under standard load and normal speeds as required by the vehicle. The timing for the first maintenance is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance: mileage and time. Whichever comes first serves as the standard. The following inspections and replacements must be completed during the first maintenance of a new car: changing the engine oil, cleaning the three filters (oil filter, fuel filter, and air filter); checking the coolant level to ensure it is normal; inspecting the vehicle's brake and clutch fluid levels; checking the power steering fluid level and looking for leaks at all fluid pipe connections; workers should inspect the generator, air conditioning, water pump, and belts for aging and tension; checking tire pressure and wear condition, adjusting tire pressure, or performing tire rotation if there is wear. When changing the oil, the oil filter must also be replaced. The choice of oil must refer to the "Vehicle Use and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not rinse the interior of the car body with water: Many people clean their cars during holidays, rinsing the body with water and wiping it with a cloth. It's important to note that the interior of the car body should not be directly washed with water. If the floor mats are dirty, use a vacuum cleaner or take them out, scrub with a brush and detergent, dry them, and then put them back. There are many drainage holes under the rubber mats on the cabin floor. If water enters, it won't dry but will flow through the holes to areas like the transmission, causing corrosion. The best practice is to clean with a vacuum and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is low, it's recommended to drain the existing antifreeze and refill with the same brand from the start. Different brands of antifreeze have varying chemical properties, and the corrosion inhibitors in one brand may corrode those in another. Different brands use different corrosion inhibitors, so they should not be mixed to avoid unnecessary issues. Do not lubricate tire bolts and nuts: When bolts on a car rust, they are often oiled to function properly again. Some people apply lubricant to bolts and nuts to prevent rust, but this can pose safety risks. At high speeds, bolts and nuts may loosen or even fall off, leading to driving hazards. Do not press the accelerator when starting an EFI car: The starter of an EFI car differs from that of a conventional car. Its fuel injection control system can automatically adjust fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.

What to Do When Taking the Driving Test (Subject 3) in the Rain?

When taking the Subject 3 driving test in the rain, you should pay attention to the following: 1. Adjust your mindset and prepare for the worst-case scenario before the test to avoid excessive nervousness; 2. Roads become slippery on rainy days, so be prepared to slow down in advance when stopping at traffic lights or pulling over; 3. Drive slowly in the rain, especially when turning or making U-turns; 4. Maintain a safe distance from other vehicles, as slippery roads increase braking distance. Subject 3 covers safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling procedures.

How to Determine the Position of the Wheels?

The methods to determine the position of the wheels are: 1. Observe the nodes on both sides of the wiper to judge; 2. Use the side mirrors to observe the door handles on both sides, where the door handles coincide with the solid lines on the ground; 3. Determine the position through the center of the windshield. The methods to judge the distance to the vehicle ahead are: 1. When the upper edge of the front vehicle's bumper is visible from the lower edge of the windshield, the distance to the front vehicle is about one meter, requiring control of the distance; 2. When the lower edge of the front vehicle's bumper is visible from the lower edge of the windshield, the distance is about two meters; 3. When the rear tire's lower edge of the front vehicle is visible from the lower edge of the windshield, the distance is about three meters.

Will points be deducted for parallel parking exceeding 30 centimeters?

After completing parallel parking, if the distance exceeds 30 centimeters, 10 points will be deducted. Other point-deduction scenarios for parallel parking include: stopping midway results in a 100-point deduction; tires touching or crossing the lane boundary lines during movement deducts 10 points; the vehicle body extending beyond the lines after parking deducts 100 points. Although the rules state that stalling the engine due to improper operation deducts 10 points once, stalling during parallel parking is equivalent to stopping midway, which directly deducts 100 points. Precautions for the Subject 2 driving test: Fasten the seatbelt: Buckle up immediately after getting in the car. Ensure the seatbelt is not fastened incorrectly or to the co-driver's side, as the system will directly deem the test failed. Do not unfasten the seatbelt during the entire test. Vehicle preparation procedure: After entering the vehicle, adjust the seat and mirrors, fasten the seatbelt, turn on the left turn signal, shift to first gear, and release the handbrake. These six steps are essential—ensure all preparations are complete before starting. No stopping during the test: There is no time limit for reversing into the parking space, but it is crucial not to stop during the process. If the wheels remain stationary for 3 seconds, the system will judge it as stopping midway, so controlling the speed is vital. Hill start time limit is 30 seconds: The hill start must be completed within 30 seconds, with the system providing a voice reminder every 10 seconds. Exceeding 30 seconds results in immediate failure.

How to Determine if a Car's Air Conditioning is Low on Refrigerant?

Methods to determine if a car's air conditioning is low on refrigerant: 1. During normal continuous operation of the air conditioning, if there are continuous bubbles in the sight glass, it indicates a lack of refrigerant; 2. Open the car hood and check for oil stains at the air conditioning system joints—if present, it indicates a lack of refrigerant; 3. During normal continuous operation of the air conditioning, if there are no bubbles in the sight glass, but brief bubbles appear when the air conditioning stops, it indicates the refrigerant level is normal. The process of refilling air conditioning refrigerant is: 1. Evacuate the system, close the manual valves on the pressure gauge and the high and low pressure manual valves; 2. Connect one end of the hose to the injection valve fitting of the refrigerant can; 3. Open the refrigerant can, loosen the nut on the pressure gauge hose to allow some gas to escape, then close it; 4. Open the high-pressure side manual valve and invert the can; 5. Inject the specified amount of liquid refrigerant, then close the refrigerant injection valve and the high-pressure manual valve.
