What are the causes of engine misfire?

Common causes of engine misfire include damaged ignition coils, insufficient air flow, intake system leaks, improper fuel pressure, and dirty or clogged fuel injectors. Below are detailed explanations and their solutions: Damaged ignition coil: Due to poor contact or excessive resistance, the ignition coil of the corresponding cylinder may become damaged, easily leading to engine misfire. In this case, the ignition coil needs to be replaced. Insufficient air flow: The powertrain control module detects that the output of the mass air flow (MAF) sensor is lower than the normal air flow, causing the air-fuel mixture to become too lean, and the exhaust gas recirculation (EGR) valve to malfunction. Professional repair shop inspection is required. Intake system leak: Air leaking into the intake system bypasses the mass air flow sensor, causing the air-fuel mixture to become too lean. Check for disconnected or damaged vacuum hoses. Improper fuel pressure: Faulty fuel pump, clogged fuel filter, or malfunctioning fuel pressure regulator can lead to improper fuel pressure, resulting in an overly lean mixture. Replace the fuel pump. Dirty or clogged fuel injector: Causes poor fuel atomization; damaged O-ring on the fuel injector. Poor fuel injector control circuit can lead to prolonged fuel injection or no injection. Clean the dirty fuel injector.

What is the penalty for a private 7-seater car carrying nine people?

7-seater car carrying nine people is considered overloading behavior. According to relevant laws and regulations, a fine will be imposed, and the driver's license will be deducted 6 points. The penalty depends on the specific situation, such as whether it is an overloaded passenger transport vehicle, other passenger vehicles, or a truck. Different vehicles have different penalties.

What to Do If the Car Stalls During Hill Start in Subject 2 Driving Test?

Starting the car by releasing the clutch too quickly without finding the semi-engaged point can cause the car to stall. When the car stalls, you should quickly press the brake pedal firmly and shift to neutral. After the car stalls, you must complete the starting operation within 30 seconds; exceeding this time will result in a failed test. When starting the car, first release the clutch until the car shows obvious vibration, then hold the clutch steady and slowly release the brake to achieve a smooth start.

How to Deal with Flooded Vehicles?

Open the drainage outlets at the bottom of the vehicle to drain all the accumulated water inside, then use large fans, hair dryers, or similar devices to dry components like the seat adjustment motors. After parking and draining the water, the vehicle owner should check the condition of the fluids in various systems. If foaming or turbidity is observed, they should be replaced promptly. After the car gets flooded, promptly dry the electrical components. If possible, use fans to dry the interior to prevent short circuits in the wiring.

What are the techniques and methods for reversing into a parking space with an automatic transmission?

Techniques and methods for reversing into a parking space with an automatic transmission are as follows: remember the gear functions, observe road conditions, understand the meaning of reverse warning sounds, and pay attention to operations on special road surfaces. Remember the gear functions: P, Park; R, Reverse; N, Neutral. Before reversing, ensure the car is completely stopped, then shift to R gear. Observe road conditions: Check all around—left, right, front, and back—for pedestrians, bicycles, motorcycles, or other vehicles. Wait for them to pass before reversing. Pay special attention to children behind the car by checking the rearview mirror and side mirrors. Understand the meaning of reverse warning sounds: Reverse sensors typically have three levels of obstacle alerts. At 1.5 meters, a mild beep sounds. At 1 meter, a faster beep is heard. Within 0.5 meters, an urgent beep is emitted. Beginners must familiarize themselves with these alerts. Operations on different road surfaces: On flat surfaces, avoid pressing the accelerator. If encountering steps or obstacles, gently press the accelerator to slowly overcome them, then brake to slow down afterward.

What is the working principle of an engine vacuum system?

The working principle of an engine vacuum system is that the vacuum pump generates vacuum for the brake booster and for controlling the exhaust gas bypass valve. The recirculation air pressure relief valve also obtains vacuum through an electric switching valve (EUV). The vacuum pump mainly consists of components such as the pump body, rotor, vanes, and intake and exhaust ports. It refers to a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container and achieve a vacuum. Functions of the engine vacuum pump: The function of the vacuum pump is to create negative pressure, thereby increasing braking force. The vacuum pump in a car generator is generally an oil pump, meaning the vacuum pump core rotates together with the generator shaft. By continuously sucking and pumping oil, negative pressure, or a vacuum, is created inside the vacuum pump housing. A vacuum pump is a device that improves, generates, and maintains a vacuum in a sealed space using various methods. Based on their working principles, vacuum pumps can be broadly classified into two types: gas capture pumps and gas transfer pumps. They are widely used in industries such as metallurgy, chemicals, food, and electronic coating.
