An exhaust treatment device of a diesel engine is provided in which combustible gas is burned with oxygen in exhaust, combustion heat increases a temperature of the exhaust, and heat of the exhaust can burn and remove PM accumulating in a DPF. In order to cause a heater for radiating heat at a start of generation of the combustible gas to enter a catalyst inlet portion, and fit a liquid fuel retaining member over a periphery of the heater, a guide plate is provided to a lower face of the liquid fuel retaining member so that the air-fuel mixture moving down in the liquid fuel retaining member flows along an upper face of the guide plate out to a periphery of the guide plate.

Exhaust treatment device of diesel engine

An engine in which an oil consumption and a leakage of blow-by gas can be stably reduced for a long period of time. The engine includes a first land (), a first ring groove (), a second land (), a second ring groove (), a third land (), a third ring groove (), and a piston skirt () formed on a piston peripheral wall () in the above-recited order from a side of a piston head (). A first pressure ring () is fitted in the first ring groove (). A second pressure ring () is fitted in the second ring groove (), an oil ring () fitted in the third ring groove (), and an indentation () is formed at the second land ().
