difference between bs4 & bs6

In the fast-paced world of two-wheelers, the transition from BS4 to BS6 engines has sparked curiosity and questions among riders. What sets these engine standards apart? Are BS6 engines truly more fuel-efficient? And how does it all relate to securing a loan for your dream ride? Join us on this informative journey as we demystify the BS4 vs. BS6 debate, empowering you with the knowledge to make confident decisions about your two-wheeler and financing options when considering a loan on a two-wheeler.

What is BS4 (BSIV)?

BS4, also known as Bharat Stage 4, refers to the emission standards set by the Indian government for differences between bs4 and bs6 vehicles. It was the prevailing standard before the introduction of BS6 (Bharat Stage 6). The key difference between BS4 and BS6 lies in the level of emissions allowed.

  • BS6 engines have significantly stricter emission norms, resulting in lower levels of pollutants released into the environment than BS4 engines.

  • This change is intended to lessen pollution and enhance air quality.

You will better know how these standards affect your choice of vehicle and its effects on the environment as we go more into the distinctions between BS4 and BS6.

What is BS6 (BSVI)?

BS6, or Bharat Stage 6, is the latest emission standard implemented in India for vehicles. It signifies a significant leap forward in terms of emission control technology. BS6 engines adhere to more stringent norms, allowing for lower levels of harmful pollutants like nitrogen oxide, particulate matter, and carbon monoxide. The introduction of BS6 aims to improve air quality and reduce the environmental impact of vehicles.

Pollution Emission Norms (BS4 vs BS6)

The shift from BS4 to BS6 brings about a notable change in pollution emission norms. This transition highlights the commitment towards a greener future and underscores the importance of choosing vehicles that comply with the more stringent BS6 standards.

Here is a detailed pollution emission norm for BS4 vs BS6-

 

Norms

BS4 Norms

BS6 Norms

Nitrogen Oxides (NOx)

80mg/km (petrol engines), 250mg/km (diesel cars)

60mg/km (petrol engines), 80mg/km (diesel cars)

Particulate Matter (PM)

25mg/km (diesel cars), not specified for petrol

4.5mg/km (diesel cars), 4.5mg/km (petrol engines)

Sulphur Content in Fuel

50 ppm

10 ppm

Additive Properties

None

Additives imitating lubrication properties of Sulphur

Diesel Particulate Filter (DPF)

Fuel Compatibility

BS6 engine requires BS6 fuel

BS4 engine using BS6 fuel increases emissions

Difference Between BS4 and BS6 Fuels

Using the appropriate fuel type is crucial for optimal vehicle performance and compliance with emission standards. BS6 fuel is required for BS6 engines, as BS4 fuel may lead to increased emissions and less efficient combustion in BS6 engines. The adoption of advanced emission control technology in BS6 fuel helps in achieving cleaner combustion and reduced pollutant emissions. So switch to BS6 fuel to support a greener and more sustainable future.

Impact of BS6 on CNG Cars:

The Impact of BS6 on CNG Cars is as follows:

  • Lower Emissions: BS6 norms have stricter emission standards, reducing pollutants released by CNG cars compared to BS4.

  • Enhanced Technology: CNG cars with BS6 compliance incorporate advanced catalyst technology to further reduce harmful emissions.

  • Improved Fuel Efficiency: BS6-compliant CNG cars often offer better fuel efficiency, optimising the utilisation of natural gas as a clean fuel source.

  • Advanced Onboard Diagnostics: BS6 standards include the implementation of Onboard Diagnostics (OBD), enabling better monitoring and diagnosis of CNG car performance.

  • Enhanced Air-Fuel Ratio Control: BS6 norms require precise control over the air-fuel mixture, resulting in improved combustion efficiency and reduced emissions.

  • Compatibility with BS6 Fuel: CNG cars designed for BS6 compliance are compatible with the lower sulphur content and improved quality of BS6 fuel.

  • Environmental Benefits: CNG cars meeting BS6 norms contribute to reducing air pollution, promoting cleaner and greener transportation.

Conclusion

BS4 and BS6 fuels differ in their sulphur content, emission control technology, and impact on vehicle performance. By adhering to BS6 standards, you contribute to cleaner air and a greener future.

FAQ:

  • What is the power difference between BS4 and BS6?

The power difference between BS4 and BS6 varies depending on the vehicle model and engine technology. Due to improved combustion efficiency and advanced technologies, BS6 engines offer better power output and performance.

  • Is BS6 more fuel efficient than BS4?

While BS6 engines are designed to be more environmentally friendly and compliant with stricter emission norms, their fuel efficiency may not be better than BS4 engines. Fuel efficiency depends on various factors, including engine design, vehicle weight, driving conditions, and individual driving habits.

Did You Know

Disbursement

The act of paying out money for any kind of transaction is known as disbursement. From a lending perspective this usual implies the transfer of the loan amount to the borrower. It may cover paying to operate a business, dividend payments, cash outflow etc. So if disbursements are more than revenues, then cash flow of an entity is negative, and may indicate possible insolvency.
