What to Do If Your Vehicle Fails the Environmental Inspection?

There are many reasons why a vehicle may fail the environmental inspection, primarily due to excessive levels of CO, HC, NO, etc. Below is relevant information about vehicle inspections: 1. Definition: Vehicle inspection, also known as annual inspection, is conducted by the traffic police department to assess the annual performance and condition of a vehicle. New vehicles are inspected every two years. 2. Exemption Policy: The Municipal Traffic Police Corps reminds that the so-called exemption only refers to waiving the on-site inspection. Vehicle owners still need to undergo a regular inspection every 2 years. After providing proof of compulsory traffic accident liability insurance, payment or exemption of vehicle and vessel tax, and resolving any traffic violations or accidents, they can directly apply to the traffic management department for the inspection label. However, if the vehicle is involved in a traffic accident causing casualties during the exemption period, the original inspection requirements will be reinstated.

Where is the ea15-ab engine produced?

ea15-ab engine is produced in Chongqing, and it is an engine independently developed by Changan Automobile Manufacturing Company. Changan OnoS is equipped with a 1.5L gasoline engine, which is the ea15-ab engine, with a maximum power of 78.5kW, a maximum torque of 145Nm, and a maximum horsepower of 107. For the daily maintenance of the ea15-ab engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected according to the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to the mechanical load, and the selection standard should not be lower than the requirements specified by the manufacturer; Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance will deteriorate, causing various problems to the engine. To avoid failures, the oil should be changed regularly according to the usage conditions, and the oil level should be moderate; When the oil passes through the fine holes of the filter, solid particles and sticky substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, the filter element will burst or the safety valve will open, allowing the oil to pass through the bypass valve, bringing dirt back to the lubrication area, accelerating engine wear and internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, mixing with metal powder generated by part wear to form sludge. When the amount is small, it is suspended in the oil; when the amount is large, it precipitates from the oil, blocking the filter and oil holes, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall life of the radiator and the engine.

What is the legal definition of a stock car?

There is no legal definition for stock cars. Here is some information about stock cars: 1. Definition: A stock car generally refers to a vehicle that remains unsold for more than three months after being manufactured and leaving the factory. Due to the emphasis on timeliness in the automotive manufacturing industry, it normally takes about one to two months for a new car to be sold to the buyer after leaving the factory. Vehicles that remain unsold for more than three months or longer are generally considered stock cars. 2. Risks: As a commodity, stock cars are large in size, expensive, and incur high storage costs. At the same time, they tie up a significant amount of the dealer's capital, so dealers generally do not allow inventory vehicles to remain in stock for extended periods.
