It is necessary to disassemble the engine and then completely and thoroughly remove carbon deposits from the components using methods such as cleaning agents or ultrasonic cleaning. Inject the cleaning agent into a machine, then pressurize it into the combustion chamber to allow the cleaning agent to react with and dissolve the carbon deposits, and finally extract the waste liquid.

I usually enjoy working on my car myself, and carbon buildup is a real headache. The symptoms are typically slow starts, severe shaking at idle, and a spike in fuel consumption. The solution is simple and straightforward: first, buy a good-quality fuel system cleaner, pour it into the tank, and fill up with gas. Then, hit the highway, maintain a speed of over 80 km/h, and keep the RPM around 3000 for about 30 minutes—this will burn off a lot of the carbon deposits. Avoid driving too slowly in the city all the time; take the highway occasionally to give it a good run. Use high-octane fuel like 95-grade and don’t skimp by using low-quality gas. For prevention: change the air filter regularly during maintenance and add fuel additives every three months. I’ve been handling it this way for years, and my car runs smoothly, with strong power and better fuel efficiency, extending the engine’s lifespan. The key is not to delay—unaddressed carbon buildup can lead to serious trouble.

Is It Normal for the Front of a Car to Get Very Hot?

It is normal for the front of a car to get very hot. The specific reasons are as follows: Reasons: When the engine is running, the external temperature can reach above 90°C, and the exhaust pipe temperature can exceed 500°C. Additionally, the heat insulation layer and underbody panels on the hood will block the dissipation of heat. Self-cooling mechanism of the car: If the engine temperature becomes too high, the fan will automatically turn on to continuously cool the engine. Once the engine temperature decreases, the fan will stop automatically. Additional information: Car bumper: The car bumper consists of three parts: the outer panel, buffer material, and crossbeam. It not only enhances the vehicle's appearance but also absorbs and reduces external impact forces, protecting the front and rear of the car body. Car engine hood: While ensuring engine heat dissipation, it provides excellent sound insulation, ensuring a comfortable ride even when the engine is running at high speeds. Moreover, the engine hood also offers dustproof and waterproof protection for the motor, battery, and various wiring inside the engine compartment.

How many meters can be captured for crossing a solid line?

There are two situations for crossing a solid line: Within 100 meters: Many beginners realize they are on the wrong path only when they reach the solid line area. For example, if you need to turn right at an intersection but are in the middle lane, you might only realize this upon reaching the intersection and attempt to change lanes at the solid line. In such cases, within 100 meters of the intersection, it's easy to be caught by traffic violation cameras. When many vehicles are queuing in the current lane: Some drivers choose to cross the line and change to a lane with fewer vehicles when facing long queues. This not only affects traffic conditions but also makes it easy to be captured by traffic violation cameras.

Is it a big deal if only 1 point is left on the driver's license?

It is not a big deal if only 1 point is left on the driver's license, as long as there are no further traffic violations resulting in point deductions within the current scoring cycle. If a motor vehicle driver's accumulated points do not reach 12 within a scoring cycle and all fines have been paid, the points will be cleared. If the points do not reach 12 but there are unpaid fines, the points will carry over to the next scoring cycle. Below is relevant information: Road traffic safety violations: The scoring cycle is 12 months, with a full score of 12 points. The cycle starts from the date the license was initially issued and continues in a loop, with points being cleared on the issuance anniversary date, which marks the beginning of the new scoring cycle. For example, if the initial issuance date of the driver's license is May 1, 2020, the scoring cycle runs from that date to the same date the following year. Point values for violations: If the accumulated points do not reach 12, the scoring system will automatically reset at the start of the next cycle. If the points reach 12, the traffic management department of the public security authority will confiscate the driver's license. The driver must then report to the traffic management department of the public security authority at the place where the license was issued or where the violation occurred within 15 days to attend a seven-day study session on road traffic safety laws, regulations, and related knowledge.

What is the proper distance for oncoming traffic in Subject 3 driving test?

When encountering oncoming traffic, it's best to maintain a 30 cm distance between the right side of your vehicle and the solid line on the right lane. Here are the relevant details: Oncoming traffic: This refers to two moving vehicles passing each other at a certain point, as you'll inevitably encounter narrow roads during actual driving.
