Stage V engines are the latest and most advanced emission standard for non-road mobile machinery (NRMM) engines. Compared to previous-stage engines, they are designed to significantly reduce emissions of pollutants, such as limiting carbon monoxide, nitrogen oxides (NOx) and particulate matter (PM).
Some of the key differences between these engines and previous stages include:
• Stricter emission regulation for particulate and NOx emissions.
• The use of advanced exhaust after-treatment systems, such as selective catalytic reduction (SCR) and diesel particulate filters (DPF).
• Improved engine efficiency, fuel efficiency and control systems.
• And mandatory on-board diagnostics (OBD) to monitor and ensure stage v compliance with the emission limits.
