What Causes Three-Cylinder Misfire and How to Fix It?

Causes of engine misfire can be divided into two main aspects. The first is damage to external components, primarily involving parts around the combustion chamber such as valves, valve seats, valve guides, and spark plugs. The second is misfire caused by the failure to ignite or delayed ignition of the air-fuel mixture inside the cylinder. Below are more detailed explanations: 1. Solutions: For the first scenario, typically inspect the spark plugs, clean carbon deposits from the intake and exhaust valves, and check the turbocharger for issues such as wear or burning on the impeller. The second scenario is usually due to an abnormal component or condition causing unstable ECU regulation of the engine, failing to meet the theoretical values calibrated by the ECU, resulting in misfire. 2. Automotive Engine: The automotive engine is the power-generating device of a car, serving as its heart and determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, automotive engines can be categorized into diesel engines, gasoline engines, electric motors for electric vehicles, and hybrid systems. 3. Other Causes: A momentary poor spark between spark plugs can lead to cylinder misfire; a stuck or improperly closed injector nozzle coil in one cylinder due to excessive self-induced voltage in the next working cycle can cause poor cylinder performance and misfire; a momentary failure of the switching transistor in the ECU due to poor heat dissipation in high-power transistors can prevent the ignition coil or independent ignition module from functioning, leading to no ignition; instability in modern integrated circuit boards and electrical components can cause many momentary faults that are hard to explain, but since the ECU receives limited signals, it can only reference the knock sensor and crankshaft position sensor to calculate misfire in a specific cylinder.

What does a circle with a P mean on a car?

The icon of a P inside a circle on the car dashboard indicates the handbrake status display, commonly known as the parking brake. In non-emergency situations, the handbrake is typically used after parking to prevent the vehicle from rolling, hence it is also referred to as the parking brake. When using the vehicle, drivers must pay attention to the handbrake warning light on the dashboard. It is absolutely forbidden to drive with the handbrake engaged, as this will increase wear on the brake calipers and brake discs, damage the vehicle's brake discs, and in severe cases, even cause the handbrake function to fail. Precautions for using the handbrake: Remember to release the handbrake before driving. Many drivers often forget to disengage the handbrake before starting the car. Driving with the handbrake engaged will accelerate the wear of the brake discs and cause the brake pads to harden due to overheating. Prolonged driving with the handbrake engaged can degrade the vehicle's performance and even damage the tires, so always release the handbrake before driving. Do not pull the handbrake too tightly. Over-tightening the handbrake can easily deform the handbrake cable, ultimately reducing its braking effectiveness. It is recommended to pull the handbrake smoothly and stop at about 70-80% of its full range. Some drivers believe the handbrake can stabilize the car, so they immediately pull it in emergencies while driving at high speeds. This is actually an incorrect use of the handbrake. Since the handbrake controls the rear wheels, locking the rear wheels at high speeds can lead to skidding, drifting, or even rollovers.

How Many Days to Wait Before Rescheduling the Written Driving Test?

You must wait 10 days before rescheduling the exam. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the written driving test (Subject 1) allows two attempts on the same day. If you fail the first attempt, you can take a free second attempt. If you fail the second attempt, the Subject 1 test is terminated. Subject 1, also known as the theoretical driving test, is part of the motor vehicle driving license assessment. The test covers driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test is computer-based with a time limit of 45 minutes. A passing score is 90 out of 100, with 100 questions consisting of single-choice and true/false questions worth 1 point each. If you answer 11 questions incorrectly, the system will automatically submit the test and end the exam. Subject 1 Test Content: Driving license and motor vehicle management regulations; road traffic conditions and rules; traffic violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 Exam Notes: Candidates must dress appropriately—no slippers allowed. Electronic devices and bags are prohibited in the exam room. Bring your ID card and queue to enter the waiting hall. Observe the instructions and procedures on the large screen, and store personal belongings in lockers before entering the exam room. After identity verification, you will be assigned a seat. Once seated, begin the test. Ensure the camera is aligned with you and follow exam rules. If you fail the first attempt, you can retake it the same day. If you fail again, you must pay to reschedule. After the test, queue to collect and sign your score report—unsigned reports are invalid. There is no limit to the number of times you can reschedule Subject 1. Each test allows one retake if you fail. If you skip the retake or fail it, the test is terminated, and you must reschedule. For Subject 2 and Subject 3, only five attempts are allowed, and rescheduling must be done after 10 days. If you fail the Subject 3 safe driving knowledge test, your passed road driving skills score remains valid. The driving test consists of three subjects: Subject 1 (traffic laws and regulations), Subject 2 (field driving skills), and Subject 3 (road driving skills and safe driving knowledge). The safe driving knowledge test is taken after Subject 3, often called "Subject 4," though this term is unofficial and not mentioned in the official regulations (Ministry of Public Security Order No. 123).

Is the Sehol Engine Made by Volkswagen?

Sehol's engine is a domestically produced engine manufactured by the Jianghuai Group. Sehol is a new brand established through a collaboration between Jianghuai Automobile and Volkswagen. Therefore, its engine is not from Volkswagen. The engine model used by Sehol is HFC4GC1.6E, with a maximum horsepower of 184, a maximum power output of 135KW, a maximum power speed of 5500rpm, and a peak torque of 300N.m. For daily maintenance of the Sehol engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions; for diesel engines, choose CB_CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine issues. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
