BSIV Engines

As India transitioned to the BSIV emission norms effective from April 1, 2017 onwards, compliance to these norms (with OBDII) requires accurate control on the engine combustion. This can only be achieved with electronic engines, and hence the Indian M&HCV market will experience a significant transition from mechanical to electronic engines.

About the BSIV Emission Norms

These advanced emission norms are aimed at reducing the environmental impact due to the increasing automobile emissions. Exhaust emissions of automotive vehicles mainly consists of carbon monoxides (CO), NOx, hydrocarbons and particulate matter. Of the various pollutants emitted by vehicles, NOx and PM significantly affect human, animal and environmental health. In BSIV norms, limit of NOx has been reduced by 30% and that of PM by 80%.

The Right Technology Matters

Cummins has in-depth expertise and understanding of BSIV equivalent norms by virtue of its experience across the globe. Countries like Europe, United States et al, have been experiencing implementation of similar and more stringent emission norms for past few decades. With the learnings from other regions and the continuous evolution of engine technology, Cummins offers BSIV engines with both SCR and EGR technologies, to offer the complete array of benefits that the two technologies can bring, thus giving customers The Power of Choice to use the Right Technology as per their needs. The electronic BSIV engines are derived from well proven Cummins’ 6BT platform which has over 20 million engines sold globally, thus making them the most reliable engines in the market. The engine will integrate Cummins’ new generation fuel system and electronic controls, while retaining the robustness and reliability of the legendary B5.9 platform.

Like one vehicle model can be used for different applications and have different duty cycles, similarly these engines with different technologies will be used to derive maximum benefit for different applications and duty cycles.

Cummins offers its customers ‘The Power of Choice’ by introducing:

- Selective Catalytic Reduction (SCR) Engines

- Exhaust Gas Recirculation (EGR) Engines

Benefits of Cummins BSIV Technology

Improved TCO than BSIII Vehicles:

By virtue of electronic engines, BSIV engine will offer better performance regards peak torque and peak torque range as compared with mechanical engines. This will improve drivability of vehicle and lesser gear shifts, thus saving fuel.

BSIV engines will offer best fuel economy in the market due to advanced fuel systems and improved combustion technology. Advanced electronics brings in new electronic features like FE switch, LBSC (load based speed control), VAM (vehicle acceleration management), duty cycle calibration tuning et al which further helps achieve improvement in fuel economy. Always putting its customer first, Cummins’ BSIV Engines offers features like the Cummins Intebrake a unique compression braking technology that offer added safety to the vehicle and increases service brake life. Cummins’ BSIV engines also features advanced filtration technology which has helped in extending the service intervals when compared with BSIII products. It also addresses inferior fuel quality issues and helps fight high degree of fuel contamination and fuel variation. This will significantly help customers in reduction of the Total Cost of Ownership of BSIV vehicles.

Higher Uptime and Longer Engine Life:

BSIV vehicles powered by Cummins engines have been undergoing intense field trials for past several months. Results indicate higher reliability and durability in comparison with BSIII vehicles. The Cummins BSIV engines are highly dependable as they are designed and proven in Indian conditions, with over 1.62 billion 6BT engines running in Indian Market. Cummins is also launching its advanced Common Rail Fuel System on BSIV ISB5.9 engines to provide better engine performance and fuel system life.

Best in Class Service Support:

To ensure field readiness for the new generation engines, the vast network of dealers have been trained and certified for addressing BSIV engine technology. Cummins has also provided training to mechanics pan India for seamless service support. Key advantage for the service network is that Cummins BSIV engine is a derivative of the BSIII platform, hence availability of common parts and excellent service support will be through the existing established sales and service network.

Components’ Integration – Cummins Fuel Systems and Aftertreatment:

Cummins ISBe5.9 engine for the first time is uniquely positioned to cater to all customer needs with the introduction of the fuel system and after treatment. Cummins’ Common Rail Fuel System offers improved performance and durability with focus on reducing the Total Cost of Ownership. The air-assisted UA2 Urea Dosing System, an essential part of any SCR after treatment system is accurately designed to reduce NOx emissions whilst increasing performance and reliability.
