Power Train – Engine: The EU Stage V Emissions Cat® C27 engine is designed for power, reliability and efficiency.

Cat C27 Engine

The Cat C27 engine with an EU Stage V emission rating is recommended for mines that require compliance with the most stringent emission standards in underground applications for customers that want to drive down diesel particulate matter and NOx emission while improving overall air quality and maintain a high machine performance. Exhaust and aftertreatment components are carefully guarded and heat wrapped. The Cat C27 Stage V engine doesn’t require a regeneration system to achieve EU Stage V emissions, therefore eliminating the need for a Clean Emissions Module (CEM) along with Diesel Exhaust Fluid (DEF). The use of 15 ppm ultra-low sulfur diesel and CJ-4 low ash engine oil are required.

An optional Cat Diesel Particulate Filter (Wall Flow Filter or Flow Through Filter) can be used to further reduce the diesel particulate matter in the exhaust. This solution also requires the use of 15 ppm ultra-low sulfur diesel and CJ-4 low ash engine oil.

Electronic Unit Injection (EUI

The electronically controlled unit injection fuel system senses operating conditions and regulates fuel delivery for optimum fuel efficiency. The proven high-pressure fuel system provides improved response times and more efficient fuel burn with lower emissions and less smoke.
