What matters,Vehicle Mission,Understanding the customer s. equipment and duty cycle,Gearing Transmission and Axle. Electronic Engine Features and,Parameters,Vehicle Power Consumption. Everything Matters,Aerodynamic Drag,Rolling Resistance. Vehicle Accessories and,Mechanical Losses,Grade Resistance.
Driveline Efficiency,Application Guidelines Terminology. Startability, The maximum grade on which a vehicle could accelerate from rest. during an idle away closed throttle start,Peak Torque Gradeability. The maximum grade that a vehicle could ascend while operating at 100. throttle in top gear at peak torque rpm,Cruise Gradeability. The maximum grade that a vehicle could ascend at a specified cruise. speed while operating in top gear at 100 throttle,Application Guidelines and Minimum.
Performance Recommendations, Certain applications may allow for cruise speed below minimum RSG Speed i e Smart Advantage. Guidance for New Equipment,Replacement Equipment, Existing equipment should dictate Minimum Performance Requirements. If tradeoffs are expected provide customer with adequate explanation and. obtain their buy in,Driveability Driver Satisfaction. Startability,Torque Peak Gradeability,Cruise Gradeability.

Maintenance,Cummins Gearing Criteria,2013 GHG 2014 Certified Engines. Max Fuel Economy, Aim to maintain the engine operating in a low rpms range. producing adequate power to accomplish the job in an efficient. manner This favors fuel economy over some performance. characteristics i e increase in shifting, Aim to operate the engine in a rpm range where horsepower is. increasing while peak torque is readily available This is a good. compromise for customers seeking decent fuel economy with. solid performance characteristics,Performance, Aim to operate the engine in a rpm range where peak power is. readily available This favors productivity over operating costs. ISX Family 1 400 475hp Gearing,Once the optimal engine is determined the right.
gearing will enable the vehicle to meet the,customer s needs and objectives. Gearing Gauge Criteria,Max Fuel Economy,Performance. New Integrated Powertrain,SmartAdvantage,ISX15 450 hp 1650 lb ft torque rating. Fuel Economy Impact,On average 1 improvement for line haul. applications,Up to 2 improvement in regional hauling with.
