Page 110: Engine Position Tracking Setup Window
National Instruments Direct Injector Driver System Manual 4.6 Engine Position Tracking Setup Window The purpose of the Engine Position Tracking (EPT) Setup window is to configure angular position tracking of the engine crankshaft for supervising the generation of engine-synchronous injection commands. The...
Page 111 National Instruments Direct Injector Driver System Manual EPT Type Pattern Type Pattern Description Selections N-M patterns have N evenly spaced teeth and M missing adjacent teeth (gap) on the crankshaft trigger wheel. M is limited to 1 or 2 missing teeth. N is stated in terms of evenly spaced teeth, as if there were no missing teeth.
Page 112 National Instruments Direct Injector Driver System Manual EPT function. This would cause the crank encoder pattern to effectively generate twice the teeth between each reference tooth seen by the EPT function. Table 4.6.a, Supported EPT Patterns Brief Glossary of EPT Function Terms CAD: Crank Angle Degrees.
Page 113 National Instruments Direct Injector Driver System Manual It is often necessary to implement filtering of the crank and/or cam signals prior to entering the EPT function. The DI Driver System software provides an integrating filter function which rejects positive and negative digital signal pulses having a pulse width less than the filter time.
Page 114 National Instruments Direct Injector Driver System Manual EPT Function Selection There are four EPT function selections available in the EPT_Type drop-down list. Each EPT function type is optimized for a particular range of number of crank teeth. For example, the DI Driver System provides two encoder pattern EPT functions, each optimized for different ranges of crank tooth counts.
Page 115 National Instruments Direct Injector Driver System Manual The EPT function will lose sync in error when missing or extra crank/cam pulses are encountered where unexpected. In all conditions, when sync is lost, CrankCount will be set to 0 and SyncStopped will be set to “Stopped”.
Page 116 National Instruments Direct Injector Driver System Manual STROKE. When tracking 720 degrees for 4-stroke engines, the camshaft input signal must be TRUE during every other crank tooth gap. This is designated by configuring the VI with Stroke = 4-STROKE. 2-Stroke Applications: Position 0 and tooth 0 coincide with the first tooth following each crank tooth gap.
Page 117 National Instruments Direct Injector Driver System Manual Plus1 tooth. As another example, if the Plus1 tooth is retarded, and NumberOfCrankTeeth = 6, then CrankCount would increment from 0 to 5, such that tooth 5 would correspond to the tooth immediately after the Plus1 tooth and tooth 0 would correspond to the second tooth following the Plus1 tooth.
Page 118 National Instruments Direct Injector Driver System Manual Figure 4.6.d, 6+1 (retarded) crankshaft trigger wheel tooth numbering Encoder Patterns Pattern Description: Encoder patterns have N evenly spaced teeth on the crankshaft with a separately sensed single reference (index, EncZ) tooth on the crankshaft or camshaft. The rising edge of the reference must occur between the same two crankshaft teeth rising edges each and every cycle.
Page 119 National Instruments Direct Injector Driver System Manual EncZ signal may be inverted via the Digital Input Setup window to properly present a rising edge between the same two crank rising edges, each and every engine cycle. Research Engine Encoder Patterns: Optical encoders are a common source of signals for this pattern type in research applications.
