Valuable engine data is now available on medium-duty trucks as it has been for years on heavy-duty applications. Access can be tricky without an investment in telematics to read and transfer data, but information such as fuel use, idle times, power take-off use, speeding, and hard braking incidents can be valuable management tools.
Background
Genesis of engine data tracking traced back to electronic engine management to monitor vehicle emissions
1991 Cummins heavy-duty engine had 6 sensors and 7 electronically controlled actuators, including fuel injectors
Comparable 2010 engine has 28 sensors and 15 actuators to monitor and control engine functions and emissions
