What are the main components of a vehicle's running system?

Causes of Unstable Idle and Easy Stalling

There are several reasons for unstable idle and easy stalling: 1. Air intake system leakage. 2. Fuel pressure too low. 3. Air filter clogged. 4. Fuel injector atomization leakage. 5. Spark plug malfunction. 6. Air flow meter failure. Below is additional information: 1. The normal idle speed of an EFI engine is determined by the idle control valve. The ECU calculates signals such as engine speed, temperature, throttle switch, and air conditioning switch, then adjusts the idle control valve to open the intake bypass channel or directly increase the throttle opening to boost air intake and raise the engine idle speed. 2. Normally, air intake must be strictly controlled. If there's an intake pipe leak, the air flow sensor cannot measure the true air intake, causing the ECU to inaccurately control the air intake and resulting in unstable engine idle.

Is Motorcycling Banned in Zhengzhou City?

Motorcycling is banned in Zhengzhou City. Below are some maintenance methods for motorcycles: 1. Spark Plug Maintenance: The spark plug is a critical component of a motorcycle engine. The proper combustion of the air-fuel mixture is key to the normal operation of the engine. 2. Air Filter Maintenance: If you frequently ride in dusty or dirty environments, you should increase the cleaning frequency. If you find the sponge broken or the paper filter element soaked, replace it immediately. Otherwise, it may damage the engine or cause black smoke. 3. Oil Filter Maintenance: During the lubrication process, the oil pump draws oil from the oil pan and first presses it into the oil filter for filtration. The filtered clean oil is then transported to the cylinder head, crankshaft, and various parts of the transmission system.

Does a new car need an annual inspection in its second year?

Yes, a new car needs an annual inspection in its second year. Normally, the annual inspection consists of two parts. The first part is to take the vehicle to an inspection station for checks on lights, tires, exhaust emissions, etc. The second part is to collect the annual inspection sticker after the vehicle passes the inspection. New cars that qualify for the 6-year exemption from inspection do not need to undergo the vehicle inspection process and can directly apply for the annual inspection sticker. For non-exempt vehicles, the owner must drive the car to a local inspection station for the vehicle inspection and collect the annual inspection sticker after passing the inspection. Vehicle annual inspection is a mandatory test for all vehicles that have obtained official license plates and registration certificates, equivalent to an annual physical examination for the vehicle based on the safety technical conditions for motor vehicle operation. Vehicle annual inspections help promptly eliminate potential safety hazards, encourage better maintenance of the car, and reduce the occurrence of traffic accidents.

What are the consequences of a clogged catalytic converter?

The consequences of a clogged catalytic converter are as follows: 1. Mild clogging: The specific manifestation of mild clogging is a reduction in the vehicle's exhaust purification capability, but no abnormalities can be detected without professional testing equipment. 2. Moderate clogging: The specific manifestations of moderate clogging include a further reduction in the vehicle's exhaust purification capability, along with increased fuel consumption, decreased engine power, and the possible illumination of the engine fault indicator light. 3. Severe clogging: When the catalytic converter is severely clogged, in addition to the above symptoms, the normal operation of the engine will be greatly affected due to the continuous accumulation of high-temperature exhaust gases that cannot be effectively expelled. This may even lead to engine stalling, and in more severe cases, the exhaust pipe may become red-hot due to high temperatures, potentially causing spontaneous combustion.
