Centinel

  • What: The Centinel is an electro-mechanical continuos oil replacement system.

  • How:

    • Option 1: Utilizes a remote oil reservoir. Based upon fuel usage, a controlled amount of engine crankcase oil is released into the fuel system via a fuel return line. The fuel & oil is further mixed in the vehicle’s fuel tank. A corresponding amount of oil is added back to the engine lube oil system from the remote reservoir.

    • Option 2: This system burns oil without a

      remote reservoir. For this system, the lube

      oil will be replenished during the daily lube

      system check or at the time of re-fueling

  • Why: This feature potentially eliminates engine

    oil change & reduces oil filter disposal

  • Benefits:

    • Reduces operation cost

    • Extends service intervals.

Water in fuel warning

Water in Fuel Warning

  • What: This feature monitors a water-in-fuel sensor & alerts the operator when there is significant water present in the fuel.

  • How:

    • OEM has to route a wire from the WIF lamp driver to the maintenance fault lamp on the dash.

    • This will light up when water is present in fuel

  • Why: This feature warns operator of potentially damaging engine fluid conditions.

  • Benefits:

    • This provides installed cost benefits by having an integrated WIF (water in fuel) sensor & controls.

    • Application Examples: All applications

Throttle Activated Diagnostic Switch

  • What: Provides the operator or technician with the capability to display faults without a cab switch while the engine is OFF & the key switch is ON

  • How:

    • With Key Switch ON & engine not running, a sequence of throttle movements will activate the diagnostic mode.

    • Every successive cycle of the throttle pedal, will lead to the next fault code.

  • Why: Allows display of fault codes without use of a Service Tool.

  • Benefits:

    • Cost savings by eliminating an additional

      switch (HD requires diagnostic switch)

      & using an existing component.

    • Application Examples: All applications


Maintenance monitor oil change monitor

Maintenance Monitor - Oil Change Monitor

  • What: This feature monitors the oil change interval of an engine & signals to the operator when an oil change is needed.

  • How:

    • Two modes of monitoring are available

    • Automatic Mode: Based on coolant temperature & load factor, adjustment is made to the oil change interval

    • Manual Mode: Based on engine operating hours.

    • OEM has to wire the appropriate I/O to the Maintenance Lamp & the lamp will be turned on to indicate need for oil change.

  • Why: Alerts operator on impending problem

  • Benefits:

    • Cost savings due to reduced down time

    • Improves durability & reliability of the engine.

    • Application Examples: All applications

Hot shutdown monitor

Hot Shutdown Monitor

  • What: This feature monitors the engine condition & records any occurrence of an engine hot shutdown.

  • How:

    • This feature is automatically enabled in the calibration.

    • The operator will be informed via a fault code the occurrence of a hot shutdown. This fault code can be tracked via a service tool.

  • Why: This feature helps track engine damage (turbocharger, exhaust manifold, etc.) due to repeated hot shutdowns.

  • Benefits:

    • The awareness of the existence of the feature could prevent operator from doing a hot shutdown that could damage engines.

    • Application Examples: Beneficial in rental markets but could be used on all applications.


Duty cycle monitor

Duty Cycle Monitor

  • What: This feature allows a Service Tool to access data that tracks the time spent in different operating regions based on an engine speed vs. torque relationship.

  • How:

    • The feature has two, 500 hour (short term) blocks of data that can be reset using a service tool.

    • After they are filled, the average load factor will continue to be calculated & broadcast but not stored until reset.

    • It also has a 50,000 hr map to store long term data. This cannot be reset.

  • Why: This feature can help identify Vehicle operating characteristics; change in operation vs. change in performance;

  • Benefits:

    • Assists with engine diagnosis

    • Application Examples: All application

  • What: This feature puts the low idle to a higher value while the engine is warming up or for a set (calibratable) period of time.

  • How:

    • If coolant temp is below a certain (calibratable) temperature, then the cold idle speed set point is used as the low idle reference for only a calibratable period of time.

  • Why: This allows for faster engine warm-ups.

  • Benefits

    • Improved performance

    • Applications Examples: All applications

Altitude derate

Altitude Derate

  • What: This feature automatically derates engine fueling based on barometric pressure.

  • How:

    • The feature is enabled via the calibration

    • Once enabled & the engine detects an ambient pressure below the calibrated limit, it will derate the engine within 1.0 sec & bring it back to normal operating conditions 1.0 sec after the normal ambient pressure is attained.

  • Why:This feature helps prevent turbochargers from over speeding at high altitudes by limiting full load torque available to the engine.

  • Benefits:

    • Cost savings from reduced down time.

    • Improved reliability of engine & equipment

    • Capable of obtaining the most torque at all altitudes
