When starting, if the throttle is pressed halfway, there is no need to bleed air. Loosen the high-pressure fuel pipe bolts on the diesel pump. After a day of rain, the filter needs to be replaced. A wet filter, air filter, or clogged exhaust pipe can cause poor exhaust flow. When replacing a new filter: 1. Clean the diesel air filter element: The exhaust valve is set at the highest point in the air conditioning system. Clean the diesel air filter element or remove dust from the paper filter as required, while observing the fuel pipe for air bleeding. Therefore, replace it with a new one and then tighten the fuel pipe bolts. 2. If cleaning is insufficient: If cleaning is insufficient, check the low-pressure fuel line from the fuel tank to the diesel pump. If fuel consumption remains high after replacement, it is not an air filter issue. Reduced air flow can lead to insufficient engine power, and the filter should be replaced if necessary. 3. Unclean conditions: Dirty oil or air filters can increase resistance.

What is the fuel consumption per 100 kilometers for the Tiida?

The Tiida currently has 4 models on sale. Among them, the Tiida TIIDA 2021 1.6L Manual Ledong Edition, equipped with a 122 horsepower engine, has an NEDC fuel consumption of 6L per 100 kilometers. The other three models—Tiida TIIDA 2021 1.6L CVT Zhixing Edition, Kudong Edition, and Zhizun Edition—also equipped with 122 horsepower engines, have an NEDC fuel consumption of 5.3L per 100 kilometers. The Tiida uses 92-octane fuel, with an average fuel price of 8.05 yuan/L. The fuel cost per 100 kilometers for different models is as follows: Tiida TIIDA 2021 1.6L Manual Ledong Edition: 6*8.05=48.3 yuan per 100 kilometers. Tiida TIIDA 2021 1.6L CVT Zhixing Edition, Kudong Edition, and Zhizun Edition: 5.3*8.05=42.665 yuan per 100 kilometers. All Tiida models have a fuel tank capacity of 50L. The distance that can be covered on a full tank is as follows: Tiida TIIDA 2021 1.6L Manual Ledong Edition: 50/6*100=833km on a full tank. Tiida TIIDA 2021 1.6L CVT Zhixing Edition, Kudong Edition, and Zhizun Edition: 50/5.3*100=943km on a full tank. Automobile fuel consumption is directly influenced by five major factors: driving habits, the vehicle itself, road conditions, natural wind, and environmental temperature. Specific factors that increase fuel consumption include: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, will increase fuel consumption. The vehicle itself: Vehicles with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power output, requiring more gasoline for combustion. Heavier vehicles also consume more fuel due to the greater driving torque needed. Road conditions: Driving on unpaved roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases vehicle resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not vaporize easily, requiring more fuel for combustion, which increases consumption. Additionally, in cold weather, the engine's computer may control higher idle speeds to warm up the engine, further increasing fuel consumption.

Does Beidou's speeding alert result in fines?

Beidou's speeding alert does not result in fines. Here is some knowledge about speeding: 1. Definition: Speeding refers to a driver operating a vehicle at a speed exceeding the legal or regulatory limits. Turbine overspeed accidents are major malignant incidents caused by failures in the turbine's speed regulation and protection systems, as well as inherent defects. 2. Preventive measures: During shutdown, first activate the emergency governor to close the main steam valve and the speed control valve, ensuring the generator's active power is zero. After the current reverses, disconnect the generator. This prevents the generator from being disconnected for too long, as the unit is inoperable during this time. Prolonged periods can cause the exhaust temperature to rise due to windage, increase the differential expansion, and significantly impact the power grid.

Is pressing the clutch for more than 5 seconds considered coasting in neutral?

During the test, if the car clutch is pressed for 5 seconds without any other accompanying operations, it will be treated as coasting in neutral. Here is more relevant information: 1. Key points of the Subject 3 test: The Subject 3 test involves frequent gear changes. You must press the brake when encountering road signs, red lights, temporary roadside parking, and entering pedestrian crossings. Pressing the brake requires pressing the clutch first. However, the Subject 3 test requires the student to stop the car immediately when intending to brake. This is a test and differs somewhat from real-world driving on the road. Gear shifting also involves pressing the clutch first and then decisively shifting gears without hesitation or keeping the clutch pressed continuously. Avoid the habit of always resting your foot on the clutch pedal. Every part of the test car is equipped with sensors and probes, and all your operations are recorded at all times. If the clutch is pressed for 5 seconds without any other operation, it will be judged as a test failure. 2. Difficulties in the Subject 3 test: Mismatch between speed and gear. You need to be aware of the errors of high gear at low speed and low gear at high speed during the test drive. Before shifting gears, you must increase or decrease the speed to match the gear, and then switch gears! During driving, remember to glance at the speedometer every eight seconds to prevent such errors.

Why should ETC be pasted on the dotted area?

ETC should be installed on the dotted area to avoid obstructing the driver's view and to ensure it can detect the toll station's detection equipment. ETC installation positions: For small vehicles such as cars and vans, the ETC card and OBU device should be installed on the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is on the lower middle part. ETC installation requirements: The height should be no less than 1.2 meters and no higher than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane). The installation process for ETC devices is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly turn on. The OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning normally. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then, peel off the protective film on the back of the OBU and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the front windshield, ensuring the chip is inserted into the OBU device.

Can You Drive Away Directly After Remote Starting the Vehicle?

After remote starting, you need to step on the brake, turn the knob, and then drive away. Here is more relevant information: 1. Remote Start: The vehicle starts the engine or motor via signals from the remote key. This entire process eliminates the inconvenience of manually entering the vehicle to operate it. While the engine or motor is running, the central locking system remains in the locked state, providing effective security. Typically, after remote starting, the engine or motor will operate continuously for ten minutes, and if no further instructions are received, it will automatically shut off. 2. Features of Remote Start: (1) High Reliability: Since the remote start of the engine or motor is structurally no different from manual ignition inside the vehicle, there is no issue of mechanical wear on the heater, significantly reducing the likelihood of failure. (2) Convenience: Although remote start cannot be timed like parking heaters, the remote start method is still very convenient. The remote range is usually no less than 50 meters, allowing you to start the engine or motor in advance from home or work if the vehicle is parked in a ground-level parking lot. (3) Automatic Timing: Typically, if no operation is performed after a certain period following a remote start, the engine or motor will automatically shut off, avoiding potential fuel waste from forgetting to turn it off. (4) Full Vehicle Heating: This function, like parking heaters, heats the coolant in the radiator, effectively warming the cabin, engine, and windows.
