In which year did China IV vehicles begin?

China IV emission standards began in 2011. Here is extended information about China IV: 1. China IV is an exhaust emission standard formulated by environmental protection departments: The larger the number after 'China', the stricter the standard, meaning the higher the number, the relatively lighter the pollution from exhaust emissions. 2. China IV emission standard is the national fourth-stage motor vehicle pollutant emission standard: The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), PM (particulate matter), etc. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the standard controls and reduces vehicle emissions to below specified levels.

Are T-engines fuel efficient?

Engines with a turbocharger (commonly referred to as "T-engines") are not fuel efficient; in fact, they tend to consume more fuel. Here are the reasons why T-engines are less fuel efficient: 1. Turbocharging (commonly known as "T"): A turbocharger pumps more air into the cylinders, which, combined with a proportional amount of fuel, significantly increases engine power. However, this also raises the working pressure and temperature in the cylinders, making the engine more prone to knocking. 2. After adding a turbocharger to a naturally aspirated engine: To control knocking, the compression ratio must be reduced, and the ignition timing must be adjusted to stabilize the combustion conditions in the cylinders. These adjustments lead to a decrease in combustion efficiency and an increase in fuel consumption.

What should I do if the engine emission warning light comes on?

When the engine emission warning light comes on, it should be handled according to the specific situation. Here are the reasons and solutions for the engine emission warning light coming on: 1. Poor fuel quality: This causes incomplete combustion of the engine mixture. Solution: When choosing a gas station, try to avoid small gas stations. Also, avoid refueling immediately after the gas station changes its oil supply. After refueling, you can add some high-quality fuel additives to improve fuel quality. 2. Dirty throttle body. Solution: Clean the throttle body every 20,000 to 30,000 kilometers. 3. Carbon buildup on valves and fuel injectors. Solution: Clean the intake and fuel system every 30,000 to 40,000 kilometers.
