What to Do If Vehicle Inspection Shows Excessive HC in Exhaust?

Solutions for excessive HC in exhaust: Use higher-grade gasoline. Higher-grade gasoline is cleaner and significantly reduces the content of harmful gases such as CO, NO, and HC after combustion. During annual vehicle inspections, using higher-grade gasoline can help purify the exhaust, making it easier to pass the inspection. Here is additional information: 1. Importance of the Three-Way Catalytic Converter: Exhaust gases are emitted through the exhaust pipe, and the three-way catalytic converter on the exhaust pipe is the most important external purification device in the vehicle's exhaust system. It converts harmful gases such as CO and HC in the exhaust into harmless carbon dioxide, water, and nitrogen. Long-term neglect of the three-way catalytic converter's maintenance can lead to blockage, reducing its ability to convert harmful gases and ultimately causing the exhaust emissions to fail standards. If the three-way catalytic converter is malfunctioning, specialized cleaning agents can be used for cleaning, or it can be directly replaced if the blockage is severe. 2. Delaying Ignition Timing to Reduce Exhaust Emissions: Delaying the ignition timing shortens the combustion time in the combustion chamber and lowers the peak combustion temperature, thereby reducing the emission of hydrocarbons and nitrogen oxides. However, this will result in a decrease in engine power. Commonly referred to as adjusting the ignition timing, this involves reducing the timing to the limit, as long as the vehicle can still reach 100 km/h on the ring road. If the adjustment is too delayed, the vehicle may not perform well, but the timing can be readjusted after the inspection.

Why Does the Engine Oil Pan Leak Fluid?

Here are the reasons for oil leakage from the engine oil pan: 1. The replaced engine oil does not meet the original vehicle standards: If the replaced oil does not match the original specifications, it can cause the oil viscosity to become too thin, leading to leakage. 2. Overfilling of engine oil: It is important to ensure the oil level remains within the normal range. 3. Loose or damaged oil drain plug: The oil pan drain plug may become loose or damaged, and the drain plug gasket plays a crucial sealing role. Below is some relevant information about the engine: 1. Introduction: An engine (Engine) is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines (such as Stirling engines, steam engines), jet engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. The term 'engine' can refer to either the power-generating device or the entire machine, including the power unit (e.g., gasoline engines, aircraft engines). The engine was first developed in the UK, so the concept of an engine originates from English, meaning 'a mechanical device that generates power.' 2. Displacement: Engine displacement is the total volume of all the cylinders in an engine, usually measured in liters (L). The cylinder displacement refers to the volume swept by the piston from top dead center to bottom dead center, also known as single-cylinder displacement, which depends on the bore and stroke. Engine displacement is a critical parameter, as it more accurately represents the size of the engine than the bore and number of cylinders. Many engine performance metrics are closely related to displacement. Generally, a larger displacement results in higher engine output power.

What documents are required for Subject 2 test?

For the Subject 2 test, you only need to bring your ID card. Below are the precautions for the Subject 2 test: 1. Mock test: The purpose of the mock test is to familiarize candidates with the test environment and allow the coach to point out areas where points are easily deducted. Therefore, the mock test is absolutely essential, and thorough preparation is the best way to face the challenge. 2. Relax: Dress comfortably before the test and be mentally prepared; pay attention to the key points when reversing into the garage, do not turn left or right; when parallel parking, ensure the rear wheels exceed the edge line of the garage, adjust the distance properly, remember to turn on the signal light and honk the horn. When making a sharp turn, judge the position accurately and turn the steering wheel decisively; when driving on a curve, make wide turns after entering the curve, maintain a steady speed, and avoid crossing any lines in all the above scenarios. 3. Signing: After the test, drive the car back to the starting position, sign to confirm, and then turn off the engine. 4. Bring your ID card: Make sure to bring your ID card to the test; without it, you cannot take the test. After all the preparation, don't let the absence of an ID card prevent you from taking the test. Additionally, ensure your phone is turned off during the test, as any activity from the phone will be considered cheating.

Do I need to study all 1500 questions for Subject 1?

Currently, the question bank for Subject 1 has exceeded 1700 questions. Whether you need to go through all of them depends on individual circumstances. After all, everyone learns at different speeds. Those with good memory naturally don't need to complete all questions, as many questions in the bank are repetitive—the same question phrased differently, rather than 1700 completely unique questions. The total duration for the Subject 1 exam is 45 minutes. The test paper consists of 100 questions, including true/false and multiple-choice questions, with a perfect score of 100 and a passing mark of 90. The exam papers are randomly selected and combined by the computer driver examination system according to the proportion specified in the "Motor Vehicle Driver's License Work Regulations." The exam content includes: basic knowledge of motor vehicles; laws, regulations, and road traffic signals; fundamentals of safe driving and civilized driving; and basic knowledge related to motor vehicle driving operations. Exam process: Follow the staff's instructions to receive your driving training file in order in the waiting area; Carry and present your ID card for inspection by the supervising officer; Mobile phones must be turned off upon entering the exam area; No loud noise is allowed in the exam area; Regulation textbooks are not allowed in the exam area (or should be placed in your bag); After the exam, collect and keep your ID card, and submit the file to the "Submission Window" at the front of the exam room; Candidates who pass the exam should sign under the guidance of the staff at the exam exit before leaving; Candidates who fail the exam may leave immediately and wait for their driving school to notify them of the retake time.

Should All Four Tires Be Replaced?

Tires can be replaced either two at a time or all four at once. When replacing two, it is essential to replace the two on the same axle. Below is relevant information about tires: 1. Tire Introduction: Tires are the only components of a car that come into contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. In fact, this practice is acceptable. 2. Tire Aging: Tires are made of rubber and will age over time. It is recommended that car owners replace their tires every four years, even if the mileage is low within those four years. This is because tires can age even when not in use for extended periods, so it is important to check the production date when purchasing new tires.

Where is the Subject 3 Test Conducted?

Subject 3 is a practical driving test, and the test location is designated by the vehicle management office on specific driving test roads. Below are the precautions for the Subject 3 test: 1. Clutch Control: The clutch should only be used when starting, shifting up, shifting down, or stopping. Avoid pressing the clutch during normal driving. When slowing down slightly in response to road conditions, only use the brake to prevent the vehicle from stalling. 2. Accelerator Control: During the road driving test of Subject 3, the traffic light will flash a few times before changing from green to red. At this point, the student must assess the distance to the intersection and the current speed. If the distance is short and the speed hasn't decreased sufficiently, pressing the accelerator can help ensure a smooth pass of the test.
