A diesel engine () has a control system () that processes certain data to develop data values for one or more temperature-dependent variables, such as injection control pressure (ICP), that affect engine starting and ensuing warm-up. The control system also processes data for detecting a temperature differential in the engine indicative of a block heater () having been used to heat the engine prior to cranking. Upon detection of such temperature differential, the control system selects a temperature data source from multiple available temperature data sources, namely engine coolant temperature ECT, engine oil temperature EOT, and charge air temperature AIT, and processes temperature data from the selected source with additional data to develop data values for one or more of the temperature-dependent variables.

Strategy for detecting use of a block heater and for modifying temperature-dependent variables to account for its use

An apparatus includes a bracket () that has at least one retainer () disposed on a first side of the bracket () and a mounting mechanism () disposed on a second side of the bracket () such that the mounting mechanism () grips a fluid rail (). The at least one retainer () retains wires () adjacent to the bracket () and away from the fluid rail (). The bracket () is disposed between the wires () and the fluid rail ().
