The DPF includes a soot filter for collecting PM (particulate matter) in exhaust gas. The engine further includes a pressure difference sensor for detecting a pressure difference between an upstream side and a downstream side of the soot filter of the DPF in a direction in which exhaust gas flows. The pressure difference sensor is supported by the fan shroud.
