Diagnostic for state of exhaust system of internal combustion engine, uses measurement of pressure difference over particle filter to evaluate diagnostic at set stable engine operating points |
摘要 |
<p>The diagnostic system measures the pressure difference across the particle filter (28) in the exhaust (22) and computes the diagnostic parameter from this measure to detect failure of the particle filter. After measuring the pressure differential, stabilized operating points for the engine are detected and the diagnostic evaluated at these points.</p> |
