Is the Zizzing Sound When Deeply Pressing the Throttle in a Turbocharged Engine Normal?

Turbocharged engines making a zizzing sound when the throttle is deeply pressed is normal; it's the sound of the turbocharger at work. A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. It utilizes the inertial force of the exhaust gases expelled by the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller then compresses the air delivered through the air filter's pipeline, pressurizing it into the cylinders. As the engine speed increases, the exhaust gas expulsion speed and turbine speed also increase synchronously, allowing the impeller to compress more air into the cylinders. The increased pressure and density of the air enable the combustion of more fuel, and by correspondingly increasing the fuel quantity and adjusting the engine speed, the engine's output power can be enhanced.

Does an AT Transmission Have Clutch Plates?

AT transmissions do have clutches. Here is some relevant information about AT transmissions: 1. AT transmissions typically refer to automatic transmissions, which are gear-shifting devices that can automatically change gears based on the vehicle's speed and engine RPM, as opposed to manual transmissions. 2. AT transmissions offer smooth performance. The torque converter can automatically and continuously adjust the torque ratio and transmission ratio within a certain range, although the torque multiplication factor is not large, and the gear range is not very wide. However, during vehicle startup or when driving on poor road conditions, the lock-up clutch can be disengaged to allow the torque converter to function, fully utilizing the hydraulic transmission's ability to automatically adapt to drastic changes in driving resistance.

What does the A on the dashboard mean?

Automobile dashboard A represents the auto start-stop function. Below is relevant introduction about auto start-stop: 1. Auto start-stop automatically turns off the engine when temporarily stopping during driving (e.g. waiting at traffic lights). When needing to proceed, the system automatically restarts the engine. This function aims to reduce emissions and fuel consumption during traffic light stops or short parking. 2. The main advantage is fuel saving - its core lies in automatically controlling engine shutdown and restart, allowing temporary engine cutoff during brief stops to avoid unnecessary fuel consumption. 3. It works by equipping traditional engines with enhanced motors featuring idle start-stop capability, enabling complete engine shutdown when meeting idle stop conditions. When restarting is needed, the idle start-stop motor system rapidly responds to driver commands, quickly restarting the engine for instant engagement, significantly reducing fuel consumption and exhaust emissions.

Is the Off Button on the Car Turned On or Off?

Car's off light mainly refers to the ESP-OFF light, where OFF stands for off. Below is the relevant introduction about the ESP-OFF light: 1. ESP represents the Electronic Stability Program, which is an active safety device mainly designed to prevent the vehicle from skidding and losing control. If the ESP-OFF light on the car is on, it means that the vehicle's Electronic Stability Program is turned off or has malfunctioned. 2. If the ESP-OFF button on the car is accidentally pressed, pressing it again briefly will turn the ESP back on. If the ESP-OFF light is on due to a system malfunction, then it is necessary to send the car to a 4S shop for repair in time. There are many reasons that can cause the malfunction light to turn on, such as circuit failure, sensor damage, Electronic Control Unit signal error, battery depletion, etc.

What Causes Exhaust Pipe Abnormal Noise?

Here are the reasons for abnormal noise in the exhaust pipe: 1. Exhaust pipe damage: The engine exhaust emits high-temperature and high-pressure waste gas, along with some backfire explosions. Therefore, the exhaust pipe must be used for noise reduction and purification. If the exhaust pipe is damaged (with gaps), waste gas will escape from these gaps, resulting in a "popping" sound. 2. In multi-cylinder engines (most car engines are four-cylinder), the exhaust processes of each cylinder are interconnected. If one cylinder stops working, the exhaust sequence will be disrupted, causing a "popping" sound in the exhaust pipe. (If the non-working cylinder is due to ignition failure or other reasons, the expelled combustible mixture will explode and burn inside the exhaust pipe, resulting in a more intense popping sound).
