What are the reasons for unstable idle speed and stalling in natural gas vehicles?

The reasons for unstable idle speed and stalling in natural gas vehicles are as follows: 1. Severe engine carbon deposits: When there is excessive carbon buildup inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in an excessively lean mixture during cold starts and making it difficult to start. Under these conditions, the engine will only start easily once the carbon deposits have absorbed enough gasoline to become saturated. After starting, the gasoline adsorbed on the carbon deposits will be drawn into the combustion chamber by the engine's vacuum suction, making the mixture too rich. This fluctuation between lean and rich mixtures causes idle speed fluctuations after a cold start. 2. Excessive carbon deposits and dirt in the throttle body and intake tract: Too much carbon buildup and dirt in the throttle body and surrounding intake tracts change the cross-sectional area of the air passage, preventing the control unit from precisely regulating the idle air intake. This leads to an overly rich or lean mixture, resulting in abnormal combustion.

Can out-of-town vehicles be traded in locally?

Out-of-town vehicles can be traded in locally, and used cars with out-of-town license plates (10 years old) can be exchanged at local 4S stores. However, it should be noted that vehicles over 10 years old generally do not meet local emission standards. Therefore, it is advisable to consult the staff at the 4S store. If the vehicle meets the requirements, the price may be relatively lower. Below is an extended introduction: Precautions for transfer: For the transfer, the owner needs to select the vehicle model and pay the purchase price. After that, the dealer will provide the owner with the manufacturer's vehicle quality certificate and a three-day vehicle movement permit, and issue the purchase invoice. When issuing the purchase invoice, the owner needs to provide their name and ID number.

What is the Wuling Hongguang PCV valve?

Wuling Hongguang PCV Valve: 1. The PCV valve is a component of the PCV system consisting of a valve body, valve, valve cover, and spring: PVC stands for Positive Crankcase Ventilation, which is commonly referred to as the active ventilation control system for the oil pan. Its primary function is to direct gases from the crankcase into the intake manifold via the PVC valve, preventing issues such as throttle icing and incomplete combustion. 2. The PCV valve is a metering control valve: It exists between the engine crankcase ventilation system and the intake system. Controlled by vacuum, it regulates the flow of oil fumes generated by the crankcase ventilation system into the intake system. 3. Operation: When the engine operates at high speeds, the flow rate is lower compared to low-speed operation. Additionally, if the engine experiences backfire, the PVC valve cuts off ventilation to prevent explosions in the crankcase.
