Which of the following most accurately describes the problem?

• Cummins' Celect electronic fuel management system has been developed to provide its 10 and 14-litre engines with variable power and torque outputs.

Celect was introduced to meet the 1991 US emission regulations, but over the past two years Cummins has worked with Navistar International to produce a driveline which would give the option of increased power and torque as needed, primarily for hill climbing.

The effect, say engineers, is that an engine rated at 231kW (310hp) for level running could produce over 320kW (430hp) with an extra 271Nm (2001bft) of torque when the vehicle starts to climb.

Although the system only works with the top few ratios, the entire transmission must be

able to withstand the higher torque input. The first engines to benefit from the updated system will be 14-litre models, but the $1,000 add-on will also work on the smaller LIO Celect units. It is said to help vehicles run cooler and slightly more economically, but could be hard to justify On the fuel savings alone.
