ISC8.3 for Medium-Duty Truck (EPA 2010)

Overview

ISC8.3 for Medium-Duty Truck (EPA 2010)Expect the same high level of performance, reliability and fuel economy with the Cummins ISC8.3 EPA 2010 engine as you do with today’s ISC.  The ISC8.3 has one of the highest power-to-weight ratios in its class with heavy-duty features like replaceable wet liners.  It also features the XPI fuel system – the same technology that’s used in the ISX15.  These advances combined with an improved Electronic Control Module (ECM) and improved air flow, allow the ISC8.3 to run stronger and with greater responsiveness than ever before.   Ratings range from 260-350hp with a maximum 1000 lb-ft of torque.

How did we make these improvements and still meet stringent 2010 emissions standards?  With a totally integrated system, that’s how.  Everything from the advanced fuel injection technology, improved cooled EGR subsystem and Cummins VGT™ Turbocharger to the proven Cummins Aftertreatment System that includes Selective Catalytic Reduction (SCR) technology has been engineered and manufactured in-house. The result is a totally integrated system delivering an engine that provides near-zero emissions without compromising performance.
 
And that’s just a few of all the features the ISC8.3 has to offer to help both your vehicles, and your business, run smoother.  These engines are designed to keep your maintenance to a minimum and your productivity in overdrive.

All backed by the best customer support in the business.

Features

XPI Fuel System - Delivers a precise quantity of fuel at ultra-high pressures.  This, together with more robust electronic engine controls, enables multiple injection events per cycle.

Heavy Duty Design - Rugged features include replaceable wet liners, roller followers, by-pass oil filtration and targeted piston cooling for longer service in the toughest work environments.

VGT™ Turbocharger - Enhanced response and control with electric actuation for infinite adjustment, providing exact boost at any rpm. Sliding-nozzle design increases reliability and durability.

Cooled EGR - Next-generation system lowers combustion temperatures for reduced emissions and optimized fuel economy.

Fully Integrated Electronic Controls - A single, higher-capacity Electronic Control Module (ECM) controls everything from air intake to exhaust aftertreatment for peak performance and near-zero emissions.

Cummins Aftertreatment System - The proven Cummins Particulate Filter reduces particulate matter by over 90%. In 2010 it is combined with Cummins Selective Catalytic Reduction (SCR) to meet emission standards while maintaining best-in-class performance, reliability and durability.

*Assuming normal duty cycle
**OEM supplied, intervals may vary
***If engine is equipped with an optional coolant filter, it will need to be replaced on the same intervals as the oil filter.  Regardless if the engine is or is not equipped with a coolant filter, SCA/DCA additive levels must be checked according to the interval listed in the owner's manual.
****Extended coolant and drain/fill/flush intervals may be followed when certain requirements are met.  For more information on these requirements, refer to the Cummins Coolant Requirements and Maintenance Service Bulletin 3666132.
