How to Know Car Engine is BS3 or BS4
Bharat Stage (BS) emission norms are a set of emission standards that are in place in India to regulate the output of air pollutants from internal combustion engine vehicles. The BS norms are based on the European Union’s emission standards, but they are tailored to suit the Indian market. The BS3 norms were introduced in 2005, and the BS4 norms were introduced in 2017. All new vehicles sold in India must meet the BS4 emission standards.
How to know if your car engine is BS3 or BS4
There are a few ways to tell if your car engine is BS3 or BS4. One way is to check the vehicle’s registration certificate (RC). The RC will state the emission norms that the vehicle meets. Another way to tell is to look for a BS4 emission control label on the vehicle. The label will be located on the engine or in the engine compartment.
Checking the Vehicle’s Registration Certificate (RC)
The vehicle’s RC is a legal document that contains important information about the vehicle, including the engine’s emission norms. To check the RC, you will need to locate the section that lists the vehicle’s specifications. The emission norms will be listed under the heading “Emission Standards”.
Looking for a BS4 Emission Control Label
The BS4 emission control label is a small, rectangular label that is attached to the engine or in the engine compartment. The label will have the following information:
- The words “BS4 Emission Control”
- The vehicle’s make and model
- The vehicle’s engine number
- The vehicle’s chassis number
Other Ways to Tell if Your Car Engine is BS3 or BS4
If you are unable to find the vehicle’s RC or the BS4 emission control label, there are a few other ways to tell if your car engine is BS3 or BS4. One way is to look at the vehicle’s exhaust pipe. BS4 vehicles have a closed-loop exhaust system that recirculates exhaust gases back into the engine. This helps to reduce emissions. BS3 vehicles do not have a closed-loop exhaust system.
Another way to tell if your car engine is BS3 or BS4 is to look at the vehicle’s engine oil. BS4 engines use a low-sulfur engine oil that helps to reduce emissions. BS3 engines do not use a low-sulfur engine oil.
Conclusion
Knowing whether your car engine is BS3 or BS4 is important because BS4 vehicles are more environmentally friendly than BS3 vehicles. BS4 vehicles produce lower levels of emissions, which helps to improve air quality. If you are considering buying a new car, it is important to make sure that the vehicle meets the BS4 emission standards.
