COLUMBUS, Ind. — Cummins says it is on track to begin full production of its ISX11.9 engine in August and that the engine has already been certified by the EPA and CARB.

Cummins said its newest engine meets EPA2010 targets of 0.01 grams per brake hp/hr of PM and 0.2 g per brake hp/hr NOx.

As with other Cummins engines, the ISX11.9 will use selective catalytic reduction (SCR) exhaust aftertreatment technology.

Cummins says the newest ISX will feature excellent pulling power and driveability and stronger clutch engagement torque making it well suited for rigorous duty cycles. It will be ideal for dump and mixer trucks as well as refuse applications, the company claims.

“Cummins is excited about the expansion of the heavy-duty product line to include the ISX11.9, which is ideally suited for vocational and specialty vehicles,” said Ed Pence, vice-president and general manager, heavy-duty engine business. “Customers can be confident that the ISX11.9 is the better choice for these applications, which require strength, performance and maximum uptime in their operations.”

The ISX11.9 will be available with horsepower ratings of 310-450 and torque ranging from 1,150-1,650 lb.-ft.

The engine has already undergone about 1.44 million miles and nearly 19,000 hours of validation testing, the company says.

Cummins also announced it has already shipped over 12,000 EPA2010-certified on-highway engines as of June.
