Cummins ISF Engine

When it comes to heavy duty diesel engines no one does it better than Cummins. The ISF is the latest addition to Cummins' extensive range of dependable engines. Based on Cummins' experience with over 4 million engines in use in on-highway applications around the world, the ISF family has been developed with high performance and low weight, specifically for light commercial applications. The engine has been designed to comply with the tough ADR 80/02 emission standards and its modualr design enables the move to the even tougher requirements of ADR80/03 with minimal impact on the installation. The new four cylinder, 2.8L common rail turbocharged and intercooled diesel engine achieves emission compliance using Selective Catalytic Reduction (SCR).

Why SCR

SCR technology is the most cost-effective method t oreduce NOx emissions and reduce our environmental impact. SCR is proven technology with over 600,000 trucks operating in Europe on SCR. It is the only technology that optimizes fuel efficiency while allowing the engine to run cleaner. SCR works by injecting a very precise amount of an automotive grade urea/water solution (called Diesel Exhaust fluid or DEF- it is also known by the trade name AdBlue) into the vehicle's hot exhaust stream. SCR has become the global standard for meeting the most stringent diesel engine emission requirements. DEF usage will be around 2-3% of diesel usage for most operators. A typical Aumark 4.5T vehicle will use about 3-4L of SCR fluid per week.
