[Problem] To provide a technology that improves maintainability of a diesel engine even when both a DPF and an SCR are provided as an exhaust after-treatment device.[Solution] A diesel engine (1) is provided with an exhaust after-treatment device (10) for purifying exhaust gas. The exhaust after-treatment device (10) comprises a DPF (20) that collects a particulate matter included in the exhaust gas, and an SCR (30) that reduces nitrogen oxides included in the exhaust gas through addition of urea. The DPF (20) is arranged to extend in an engine front-rear direction, which is a direction parallel to a crankshaft (CS), while the SCR (30) is arranged to extend in an engine width direction rearward of the DPF (20) in the engine front-rear direction.
