What are the hidden features in the 2021 Excelle?

What age group is the Teana suitable for?

Teana is suitable for people aged 30-39. Here is some relevant information about the Teana: 1. Name origin: The name comes from an indigenous American language, meaning dawn, symbolizing the emergence of Nissan's new generation of mid-to-large-sized sedans. One of the most notable features of the Teana is its modern and tasteful interior, with extensive use of wood grain panels, giving it a high-end and sophisticated appearance. 2. Competing models: The Teana competes with Audi's products, the Buick Regal, Toyota Camry, and Honda Accord's high-end models. Nissan has placed high hopes on the Teana to 'redefine the domestic luxury car market.'

What is the difference between gas and gasoline as fuel?

The differences between gas and gasoline as fuel lie in the type of fuel, safety aspects, and fuel storage methods. Here are the specific details: 1. Advantages of using natural gas in cars: Higher ignition point. The ignition point of natural gas is above 650°C, which is 223°C higher than that of gasoline (427°C), making it less prone to ignition compared to gasoline; Lower density. With a relative density of 0.48 compared to air, leaked gas disperses quickly in the air, making it difficult to reach a concentration that can ignite; Higher octane rating. It can reach up to 130, much higher than the current best 96-octane gasoline, providing excellent anti-knock performance. 2. Advantages of using gasoline in cars: Gasoline has better volatility, making it easier to ignite, and its liquid form makes storage more convenient. Consider today's hydrogen-powered vehicles, where transporting and storing hydrogen incurs significant costs.

What does the EPC light on the car's center console mean?

The EPC indicator light has two illumination states: during power-on self-test and under other circumstances. The power-on self-test is an indication that the vehicle is monitoring the status of all sensors before driving. Generally, if the vehicle is not started after power-on, the light will turn off by itself after about 3 seconds. If the EPC light remains on under other circumstances or does not turn off for a long time after the vehicle is started, the possible causes include faults in the engine intake system, throttle, fuel system, engine, ECU control unit, or brake lights. Below is a detailed introduction to the causes of the EPC light illuminating under other circumstances: Engine intake system fault: The EPC light will illuminate if the engine intake is obstructed or insufficient. Throttle fault: Carbon buildup is a common issue with the throttle. Additionally, dirt on the throttle body can affect intake, causing the indicator light to illuminate. Fuel system fault: This includes issues such as substandard fuel, deteriorated fuel, or poor fuel atomization. Engine fault: Insufficient engine pressure or problems with the power system, such as the intake valves, can also trigger the EPC light. ECU control unit fault: For example, interference with the vehicle computer signals or false alarms from the vehicle computer. Brake light fault: This includes situations where the brake lights do not illuminate, the brake switch malfunctions, or there are issues with the brake wiring. Solutions for when the EPC light illuminates: Troubleshoot the intake system, use fuel with the appropriate octane rating, clean the throttle, etc. Remove carbon deposits from related components. Re-flash the ECU with relevant data. If the EPC light illuminates, the owner can first try turning off the engine and restarting it to see if the EPC light remains on. If it does not, there may be no issue, and the EPC light may have been affected temporarily. If the EPC light remains on or frequently illuminates, the vehicle should be taken to the nearest repair facility for professional diagnosis and repair to eliminate potential safety hazards promptly. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system mainly includes controllers and sensors related to the power system. When the sensor data in the system is abnormal, the EPC system will take measures on the power system according to preset programs. Common EPC indicator lights are generally displayed in two colors: yellow and red. If the EPC fault light is yellow and the vehicle can still operate normally, drive slowly to a repair point for inspection. If the EPC fault light is red, the situation is more severe, and the vehicle should be pulled over immediately, with professional repair personnel contacted for assistance. Continuing to drive could directly affect the vehicle's core components or driving safety.

What is the reason for the low coolant warning disappearing after restarting?

If the coolant warning light disappears after restarting, it is recommended not to continue driving. You can add coolant before resuming vehicle use. Function of automotive antifreeze: Another name for automotive antifreeze is coolant, which helps lower the engine temperature. Since the engine generates a significant amount of heat during operation, 60% of this heat is dissipated into the surrounding space through the cooling system. Water and methanol-based coolants have a low boiling point and are prone to boiling. If the vehicle operates under conditions where the coolant boils, even for a short period, it can cause engine damage or even complete failure. Precautions when replacing antifreeze: It is essential to use the same type of antifreeze as originally specified. Different types of antifreeze have varying chemical compositions, and mixing them can lead to sedimentation and crystallization. Additionally, the cooling effectiveness of the antifreeze may be reduced. Therefore, only the same type of antifreeze as originally used should be employed.

Can You Start on a Slope Without Pressing the Clutch?

You can start on a slope without pressing the clutch. Here are the details: 1. Clutch: Commonly known as "gei lik zi" in Hong Kong, derived from the English word "Clutch," it is a device that switches the engine power of a car or other power machinery to the axle. 2. Function of the Clutch: The clutch is installed between the engine and the transmission and is the assembly in the car's drivetrain that directly connects to the engine. Typically, the clutch is mounted together with the engine crankshaft's flywheel group, serving as the component that cuts off and transmits power between the engine and the car's drivetrain. Throughout the process from starting to normal driving, the driver can operate the clutch as needed to temporarily separate or gradually engage the engine and the drivetrain, thereby cutting off or transmitting the engine's power output to the drivetrain. Its role is to allow gradual engagement between the engine and the transmission, ensuring smooth starting; temporarily disconnect the engine from the transmission to facilitate gear shifting and reduce impact during shifting; and act as a separator during emergency braking to prevent overload in the transmission and other drivetrain components, providing a certain level of protection.

Will the brake become hard after stopping for several hours?

Brakes may become hard after stopping for 12 hours. Here are the specific details: 1. Reason: It is normal for the brake to become hard when the engine is off. When the vehicle is running and the brake is pressed, the brake vacuum booster pump operates, utilizing the engine's vacuum to provide assistance. After the engine is turned off, the vacuum level disappears as the engine stops working, and the brake vacuum booster pump ceases to function, causing the brake to become very hard. 2. Introduction to the Brake System: A car moves on the road due to the rotation of its wheels. When the car needs to stop, the driver cannot extend their foot to the ground like in cartoons to halt the vehicle. Instead, the car relies on its braking system to reduce speed and come to a stop. The braking system generates friction between the brake pads and the drum or disc, converting the kinetic energy of the moving car into heat energy during the friction process, thereby dissipating it.
