What are the differences between the 9NR and 8NR engines in the 2019 Corolla?

Does It Consume Fuel Without Pressing the Accelerator?

It does consume fuel even without pressing the accelerator. To keep the engine running, a certain amount of fuel must be consumed; otherwise, the car will stall. For example, when the car is idling in neutral, the engine maintains idle rotation, during which the system still requires a small amount of fuel injection. Therefore, under normal circumstances, the fuel injection process continues. Below are some driving tips: Check the rearview mirrors: Always use turn signals and slow down when turning or changing lanes; always check the rearview mirrors before turning. Left turns mainly require checking the left rearview mirror, right turns mainly the right rearview mirror, and both left and right turns require checking the interior rearview mirror. Don't stare at the front of the car: When driving on a clear road, look straight ahead at about 100 meters, not at the immediate front of the car. Press the clutch: Generally, when decelerating at speeds above 40 km/h, there's no need to press the clutch first; press it when the speed drops to around 20 km/h. Steering: Turn the wheel slowly for high-speed turns and quickly for low-speed turns.

How to Activate the Warm Air in Corolla Hybrid?

Activation method: There is a knob on the air conditioning system. Rotate the indicator mark on the knob to the maximum red position, turn on the internal circulation inside the car, and then turn on the fan after the water temperature rises to blow out warm air. Working principle: The hybrid uses automatic air conditioning. The warm air is generated by both the electric heating wire and engine heat exchange. In winter, you only need to set the temperature, for example, my car is set at 25 degrees Celsius when the outside temperature is 3 degrees Celsius. At this time, when starting the car, the engine will start but the air conditioning vents will not blow air. Only when the temperature of the electric heating wire also rises will it start blowing air. However, during driving, the main heat source still relies on the engine. The heat from the electric heating wire only assists when the car is running purely on electricity. If the temperature falls below the set level, the engine will still intervene, which is why the hybrid's fuel consumption in winter is higher than in summer. Corolla Hybrid E+: The Corolla Hybrid E+ is the most affordable hybrid model currently sold in China.

What are the reasons for Chevrolet's infotainment system being unable to connect to the internet?

Chevrolet's infotainment system being unable to connect to the internet may be due to the following reasons: Requirement to install an APP: Taking the all-new Toyota Camry as an example, it has smartphone connectivity features but requires downloading a Lexus APP on the phone to establish the connection. Many car owners have likely encountered this issue. This could be because the vehicle connectivity function requires payment of software management fees to Android or Apple, leading some automakers to develop their own linking software in mobile clients to bypass these costs. System incompatibility: All car manufacturers that want to enable smartphone connectivity must pay software fees to Android or Apple. Therefore, some brands, based on the usage habits of their target market, may only purchase compatibility with Android or Apple systems. If your phone's operating system conflicts with the vehicle's system, it naturally won't connect. Substandard data cable: Beyond the aforementioned system and software issues, another critical factor in smartphone-to-car connectivity is hardware. It's known that each phone comes with only one original data cable, typically used at home for charging, carried around, or kept in the car for charging purposes.

How often should the fuel pump be replaced?

Fuel pumps generally need to be replaced around 100,000 kilometers. Here are the specific details about automotive high-pressure fuel pumps: 1. Function: The fuel pump serves as the interface between the high-pressure and low-pressure fuel circuits, controlling the fuel output to generate fuel pressure in the common rail. Its role is to increase fuel pressure for high-pressure injection to achieve atomization. 2. Purpose: The primary use of fuel pumps is as a power source for hydraulic devices such as jacks, header machines, extruders, and cotton gins. 3. Installation precautions: During the installation of the fuel pump, all openings should be covered to prevent foreign objects from entering the machine.

How often should the transmission fluid of a Vios be changed?

The transmission fluid of a Vios is generally recommended to be changed every 2 years or approximately 60,000 kilometers. The replacement cycle varies for different models. Below are the replacement intervals for transmission fluid: Manual Transmission: Manual transmission fluid is typically recommended to be changed every 3 years or approximately 100,000 kilometers. Automatic Transmission: Automatic transmission fluid is generally recommended to be changed every 2 years or approximately 40,000 kilometers. Continuously Variable Transmission (CVT): CVT fluid is usually recommended to be changed every 2 years or approximately 60,000 kilometers. The methods for changing transmission fluid are as follows: 1. Loosen the drain screw at the bottom of the transmission to drain the old fluid, then refill with new fluid. 2. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it removes impurities settled at the bottom of the oil pan. 3. Use a circulation machine to change automatic transmission fluid: A smart circulation machine performs dynamic fluid replacement, filtering and cleaning sludge and impurities inside the automatic transmission.

What Causes the Popping Sound from a Car's Exhaust Pipe?

The popping sound from a car's exhaust pipe can be caused by issues such as blocked or unobstructed fuel lines, rail pressure problems, abnormal electric fuel pump operation, or a clogged fuel filter due to various reasons, leading to restricted fuel flow. Below are the functions of a car's exhaust pipe and usage precautions: Functions of a Car's Exhaust Pipe: For the car body, the exhaust pipe plays a role in vibration damping and noise reduction, as well as extending the lifespan of the exhaust muffler system. The main material of the exhaust pipe is stainless steel. For most vehicles, since the exhaust gases leave the engine under high pressure, the noise generated can be extremely irritating. The primary function of the car's exhaust pipe is to reduce this noise. Precautions for Using a Car's Exhaust Pipe: The first thing to note is to prevent water from entering the muffler. When driving on deep water roads or during car washing, care should be taken to avoid water entering the muffler. If water accidentally enters, the engine should be started and idled for at least 10 minutes to allow the internal water to drain as much as possible.
