4.0 Engine Ratings
Overview
The engine rating states the peak power and torque of the engine. The engine is
available with several power ratings, allowing the engine to provide the correct
amount of power to complete the job while limiting the torque within driveline
component limitations. Increasing the power rating may put main driveline
components at risk for premature wear or damage.
Two MX-13 ratings and one MX-11 rating are available with Multi-Torque; these
ratings are identified by the MT in the option name. Multi-Torque engine ratings
provide an increased maximum torque output in the top two gears of rated
transmissions. The increased torque delivery from Multi-Torque is represented in
Graph 4.2 and Graph 4.4 as dashed lines.
Two refuse engine configurations are available for the MX-11, which provide specific
turbocharger and engine brake control strategies to allow for quieter operation.
MX-13 Standard Feature
Note: Due to differences in engine hardware on the MX-13, re-rating engine
horsepower cannot be performed between engines with ratings of 455 HP or
less and engines of 485 HP or more.
