摘要： A particulate accumulation amount estimating system is configured to accurately estimate an amount of particulate matter accumulated in a particulate filter based on the pressure difference across the particulate filter even when ash is accumulated in the particulate filter. The particulate accumulation amount estimating system is configured to estimate a particulate accumulation amount of particulate matter accumulated in the particulate filter based on a pressure difference that was detected across the particulate filter and an effective area change of the particulate filter that was detected due to the accumulation of ash in the particulate filter. The estimate of the particulate accumulation amount based on the pressure difference across the filter will be lower as the estimate value of the ash accumulation amount becomes larger.

摘要： In an engine (10) comprising a fuel injector (12) which performs a post injection after performing a main injection into a cylinder and an exhaust valve (15) which opens and closes to discharge an exhaust gas, a controller (70) controls the fuel injector (12) to start the post injection during a period where a gas velocity in the cylinder along a cylinder axis increases after the exhaust valve (15) opens. A duration (t) of the post injection is controlled according to a crank angle at which the post injection is to be performed such that a breakup distance (L) at the end of which the injected fuel atomizes does not become larger than a distance (S) from an injection hole (12a) to a cylinder liner (10c), thereby ensuring that the injected fuel is supplied to an exhaust passage (23) without adhering to the cylinder liner (10c).
