Abstract:This record refers to both the spreadsheet tool - Fleet Equipment Performance Measurement Preventive Maintenance Model: Spreadsheet-Based Engine Data Analysis Tool, http://ntl.bts.gov/lib/60000/60000/60007/0-6626-P1_Final.xlsm - and its accompanying user manual - Spreadsheet-based engine data analysis tool - user's guide, http://ntl.bts.gov/lib/60000/60000/60007/0-6626-P1.pdf.
The concept of preventive maintenance is very important in the effective management and deployment of
vehicle fleets. The Texas Department of Transportation (TxDOT) operates a large fleet of over 17,000 pieces
of on-road and off-road equipment. Newer engines and vehicles are equipped with on-board diagnostic
systems that can provide data on engine operation—including engine speed and throttle position (an
indication of load value). There is the possibility of tracking these parameters to refine predictions for when
equipment maintenance should be performed. Project 0-6626 aimed to provide a proof of concept for this
idea by developing an algorithm that can be used to recommend appropriate oil change intervals based on
engine data collected through on-board diagnostic systems. This product is a spreadsheet-based analysis tool
developed as part of Project 0-6626, which can be used for logging, analyzing, and characterizing engine
data for heavy-duty fleet vehicles in the TxDOT fleet of the selected test vehicle type.
