- Multi-Flame Rod Combustion Control for Misfire Detection
Multiple flame rods cross-check flame current to detect misfires and stop fuel supply before raw gas is emitted.
- Air Cycle Machine Speed Monitoring for Bearing Failure Shutdown
Rotational speed and deceleration thresholds flag erratic air cycle machine behavior early enough to shut down before bearing wear and emissions occur.
- On-Road Driving Test Evaluation Using Virtual and Bench Models
Combining virtual simulation, bench testing, and real-road results improves RDE-compliant vehicle evaluation while reducing model setup effort.
- Cylinder Compression Evaluation via Starter Battery Voltage
Battery voltage minima during engine startup reveal uneven cylinder compression without disassembly, helping flag engine faults early.
