CPCB IV+ Compliant gensets are incredible engineering achievement

These eco-friendly generators slash PM and NOx emissions by 90 per cent, offering superior performance and reduced environmental impact.

According to Manoj Nair, Power Generation Business Leader, Cummins India, CPCB IV+ compliant gensets in India herald a new era in emissions reduction. These eco-friendly generators slash PM and NOx emissions by 90 per cent, offering superior performance and reduced environmental impact.

How are CPCB IV+ compliant gensets from Cummins India making a positive environmental impact?

Cummins India’s CPCB IV+ compliant generators, introduced on July 5, 2023, represent a significant engineering feat. These machines have evolved from basic mechanical devices into advanced electronic technologies with intelligent control systems, advanced exhaust treatment, remote monitoring, and predictive maintenance. This transformation has resulted in an impressive 90% reduction in particulate matter (PM) and harmful nitrogen oxide (NOx) emissions compared to CPCB II standards. This achievement allows customers to meet backup power needs while promoting environmental sustainability. This strategic shift ensures compliance and aligns with our innovation and eco-friendly power generation commitment.

What are the primary objectives of the CPCB IV+ emission standards?

The CPCB IV+ emission norms, mandated by the Ministry of Environment, Forest, and Climate Change, are part of the Indian government’s efforts to reduce air pollution nationwide. These updated standards simplify regulations by applying a unified standard to portable and stationary generators up to 800 KW in capacity, regardless of fuel type. This streamlines manufacturing processes.

Additionally, these standards promote the adoption of cleaner emissions technologies, reducing greenhouse gas (GHG) emissions and generator fuel consumption, in line with our nation’s environmental goals.

How does the closed-loop system with real-time monitoring enhance the performance of gensets?

The closed-loop system, with real-time monitoring, enhances generator efficiency and reliability. It continuously assesses performance and emission compliance, triggering alerts for deviations and enabling quick corrective actions.

Customers receive alerts via SMS and email, minimizing downtime and maintaining peak generator performance, ultimately extending their lifespan.

Discuss the advanced after-treatment systems in gensets. What is their role in enhancing fuel efficiency?


Cummins gensets feature advanced after-treatment systems comprising DOC, SCR, and DPF/PFF modules. These systems enhance fuel efficiency and emissions compliance, with module configurations tailored to system size and capacity for efficient fuel combustion and pollutant control.

Remote monitoring streamlines generator management from anywhere, enhancing efficiency and responsiveness. Swift remote operation initiation and shutdown, especially in emergencies, ensure rapid power deployment. It also facilitates system status checks, fault detection, and immediate notifications, reducing operational and maintenance costs.

What are fuel and DEF sensors’ benefits in improving generator efficiency?

Fuel and Diesel Exhaust Fluid (DEF) sensors ensure peak efficiency. Real-time fuel sensors monitor diesel consumption, allowing immediate corrective measures if excessive fuel is used. Beyond performance improvements, they cut operational costs and emissions, contributing to environmental sustainability.

Furthermore, Diesel Exhaust Fluid (DEF) sensors ensure compliance with emissions standards by precisely controlling the injection of DEF, which reduces harmful nitrogen oxide emissions. Together, these sensors significantly boost generator efficiency, lower operational costs, and help meet rigorous environmental regulations.

How do you employ innovation and advanced digital tools to address environmental challenges and climate change?

Cummins is deeply committed to innovation and environmental responsibility, with core values centred on clean air, water, and a healthier planet. With over a century of global experience and six decades in India, we use advanced digital tools, meet strict emissions standards, and customize products for market and customer needs. Our CPCB IV+-compliant generators exemplify this commitment, offering clean, adaptable power solutions prioritising environmental sustainability.

What advantages do these gensets offer in emissions compliance?

CPCB IV+ compliant generators offer significant emissions reductions and environmental benefits. They cut PM and NOx emissions by 90% through advanced engine technology and after-treatment systems, improving performance, fuel efficiency, and reliability.

Furthermore, these generators eliminate the need for costly retrofit devices or dual fuel kits, reducing the total ownership cost. These technological advancements align Indian generators with global standards, creating export opportunities for the industry.
