EXHAUST GAS PROCESSING APPARATUS OF TRACTOR

摘要

PROBLEM TO BE SOLVED: To enable a diesel particulate filter for purifying an exhaust gas of a diesel engine to be stored in a narrow space in an engine hood and thereby effectively utilize heat generated by the engine.SOLUTION: An exhaust gas processing apparatus of a tractor purifies an exhaust gas of an engine (E) mounted in an engine hood (50) of a tractor by using a diesel oxidation catalyst (DOC) and a selective catalytic reduction (SCR) system. In the exhaust gas processing apparatus, the exhaust gas from the engine (E) is led to the DOC (71) horizontally mounted on an upper part of the engine (E). Further, the exhaust gas is led to the SCR (73) erected at a side part of the engine (E) to be exhausted from an exhaust pipe (78) into outer air.
