What is a BS6 Engine & How BS6 Engines work, BS4 Vs BS6
Last Modified: 8-November-2024
The automobile industry in India has experienced a significant shift with the introduction of BS6 engines, which replaced the older BS4 engines. If you’re planning to buy a vehicle, especially a two-wheeler, it’s important to understand what the BS6 engine is, how it works, and how it differs from the BS4.
The shift from BS4 to BS6 was driven by environmental concerns, with the government enforcing stricter emission norms under Bharat Stage 6 regulations. This transition has not only changed engine design and functionality but also influenced how we finance and calculate loans for these vehicles. Whether you’re using a two-wheeler loan calculator or seeking bike finance, it’s essential to understand what BS6 means in bikes and cars, how it operates, and how it compares to BS4.
What is BS4 (BSIV)?
BS4, or Bharat Stage 4, was the emission standard set by the Indian government for vehicles before BS6 was introduced. It regulated the amount of pollutants vehicles could emit but allowed higher levels compared to the newer standard.
What is BS6 (BSVI)?
BS6, or Bharat Stage 6, is the latest emission standard by the Indian government to reduce vehicle pollution. A BS6 engine is designed to meet stricter limits on pollutants like carbon monoxide, nitrogen oxides, and particulate matter, ensuring cleaner and more eco-friendly performance.
How do BS6 Engines Work?
The transition from BS4 to BS6 involved significant technological advancements. To meet the Bharat Stage 6 norms, manufacturers made several modifications to the existing engines. The following are key changes that explain how BS6 engines work:
- Advanced Catalytic Converters: BS6 engines are equipped with advanced catalytic converters to reduce harmful emissions. The converters help to break down pollutants like nitrogen oxides into nitrogen and oxygen, making them less harmful.
- Diesel Particulate Filters (DPF): BS6 diesel engines are equipped with DPFs, which capture and store exhaust soot to reduce particulate emissions.
- Selective Catalytic Reduction (SCR): SCR is another component that is used to inject AdBlue (a urea-based solution) into the exhaust system, converting nitrogen oxides into nitrogen and water.
- On-board Diagnostics (OBD): BS6 engines come with OBD, which monitors the performance of emission-related components to ensure compliance with emission standards throughout the vehicle’s lifecycle.
The combination of these systems in BS6 engines ensures a drastic reduction in harmful emissions compared to the previous BS4 standards.
Emission Control Technologies: BS6 engines are equipped with additional emission control technologies like a second catalytic converter and a complex exhaust gas recirculation system, which further reduce harmful emissions and improve engine efficiency. Adding such specific technical details can help readers understand the practical changes in engine technology due to BS6 norms.
BS4 vs BS6: Key Differences
Let’s explore the differences between BS4 and BS6 engine:
Aspect | BS4 | BS6 |
Emission Standards | – Emitted higher levels of pollutants such as nitrogen oxides (NOx), particulate matter (PM), and hydrocarbons. | – Significantly reduced emissions, with nitrogen oxide emissions from diesel engines reduced by almost 70% compared to BS4. |
Fuel Quality | – Contained higher sulfur content, around 50 ppm (parts per million). | – Reduced sulfur content to 10 ppm, making it cleaner and less polluting. Requires BS6 fuel for optimal performance. |
Engine Performance | – Efficient but lacked advanced emission control mechanisms. | – Equipped with advanced technologies like SCR (Selective Catalytic Reduction), DPF (Diesel Particulate Filter), and OBD (On-Board Diagnostics) systems, leading to more efficient and cleaner combustion. |
Mileage | – Known for better mileage due to fewer emission control mechanisms. | – Slightly reduced mileage due to complex emission control systems, but benefits include significantly reduced pollution. |
Maintenance | – Simpler engines with fewer emission control components, resulting in less expensive maintenance. | – More frequent maintenance may be required due to advanced technologies like catalytic converters and DPF. Higher-grade lubricants may also be necessary. |

Impact of BS6 on Two-Wheelers
When it comes to two-wheelers, “what is BS6 in bikes” refers to the application of Bharat Stage 6 emission norms to motorcycles and scooters. Two-wheeler manufacturers have integrated the necessary technologies to comply with the new standards.
The BS4 vs BS6 bike difference is noticeable in the fuel injection systems. While most BS4 two-wheelers had carburettors, BS6 bikes come equipped with electronic fuel injection systems. This makes BS6 bikes not only more efficient in fuel combustion but also cleaner in terms of emissions.
Financing a BS6 Vehicle: Two-Wheeler Loan Calculator and Bike Finance
If you’re considering purchasing a BS6 vehicle, especially a bike, it’s important to consider the cost implications. BS6 bikes may be slightly more expensive due to the technological advancements, but the benefits of lower emissions and cleaner engines are worth the investment. This is where bike finance options can help.
