What are the causes of engine knocking?

Automobile engine knocking occurs due to the following reasons: 1. Excessively advanced ignition timing: To ensure the piston receives power immediately upon entering the power stroke after reaching top dead center (TDC), ignition typically occurs before TDC. However, excessively advanced ignition causes most of the air-fuel mixture to burn while the piston is still in the compression stroke. The remaining unburned mixture then undergoes extreme pressure and spontaneously ignites, resulting in knocking. 2. Severe carbon buildup in the engine: Excessive carbon deposits in the combustion chamber not only increase the compression ratio (generating high pressure) but also create hot spots on the carbon surface, leading to engine knocking. 3. Overheating engine: High intake air temperatures in hot environments or poor engine coolant circulation can cause the engine to overheat and knock. 4. Incorrect air-fuel ratio: An overly lean air-fuel mixture raises combustion temperatures, which in turn increases engine temperature, making knocking more likely. 5. Low fuel octane rating: The octane rating indicates a fuel's resistance to knocking. Higher octane fuels have better anti-knock properties. High-compression engines generate higher combustion chamber pressures. Using low-octane fuel with poor anti-knock properties increases the risk of knocking.

Why does the car feel sluggish when accelerating with the air conditioning on?

Reasons for sluggish acceleration when the car's air conditioning is on: The air conditioning increases the engine load, especially during hot summer days when fuel vapor increases relatively, leading to a decrease in fuel pressure within the fuel system. Additionally, a clogged fuel filter can result in insufficient fuel supply. Below are some related factors affecting car acceleration: 1. Besides fuel, the engine also requires air. If components like the air filter or throttle are clogged or malfunctioning, causing insufficient air intake, it can lead to sluggish acceleration. 2. Poor ignition from the spark plugs may also cause acceleration issues. 3. Exhaust system problems, primarily referring to poor exhaust flow, often caused by a broken catalytic converter, can lead to a blocked exhaust pipe, reducing engine power.

Can I drive if my driver's license has no points left?

You cannot drive if your driver's license has no points left. If you accumulate 12 penalty points within 12 months, you must attend a mandatory course at the vehicle management office within the specified time. Failure to do so will result in automatic revocation of your driver's license. Below is relevant information about driver's licenses: 1. A driver's license, also known as a driving permit, is an official document issued by the government transportation department to individuals who meet the qualifications for driving. To obtain a driver's license, one must meet the age requirements and pass the driving test. 2. The driver's license examination consists of four sections: theoretical knowledge, field driving skills, road driving skills, and knowledge related to civilized driving. The basic process for obtaining a driver's license includes filling out forms, undergoing a physical examination, application acceptance, fee payment, taking the test, and license issuance.

The Correct Method for a 7-Speed Wet Dual Clutch at a Red Light?

For a 7-speed wet dual-clutch transmission at a red light, you can keep it in D gear while holding the brake, or shift to N gear. Below is some relevant information about the 7-speed wet dual-clutch transmission: 1. A 7-speed dual-clutch transmission is a dry clutch type, typically paired with small-displacement engines. 2. How the 7-speed dual-clutch transmission works: It consists of three similarly sized clutch plates installed coaxially in a stack. The two outer clutch plates are connected to gears 1, 3, 5, 7 and gears 2, 4, 6, and reverse, respectively. The middle plate moves between them, engaging or disengaging with the two clutch plates to shift gears.

What are the reasons for the FAW J6 having power but no response when starting?

The main reasons for the FAW J6 not starting are: 1. Weak battery: A weak battery doesn't mean it's completely dead, but the voltage is insufficient to start the car. You can try jump-starting or replacing the battery. 2. Damaged spark plugs: Worn-out spark plugs are one of the reasons a car won't start, as spark plugs are needed to ignite the gasoline in the cylinders for the engine to run. 3. Distributor circuit failure: The main circuit for starting is the distributor; if it's damaged, it may prevent ignition. 4. Starter motor damage: The starter motor is responsible for turning the engine during ignition; if it's damaged, the car won't start.
