摘要 |
A system and method for controlling an internal combustion engine monitor exhaust back pressure and take remedial action when the exhaust back pressure exceeds a corresponding threshold. The system and method respond to increased exhaust back pressures attributable to various causes to alert the vehicle operator and/or engage engine protection mechanisms depending on the back pressure severity level in an effort to avoid engine/component damage. Fault timers are provided for tracking time fault conditions are present and time that faults are active, with active faults being latched for the current ignition cycle. Available engine torque may be reduced in response to excessive exhaust back pressure. Anti-tampering logic is provided to detect attempts to defeat the protection feature. |
