Definitions
- the present invention relates to an exhaust gas purification device.
- Particulate matter (particulate matter) emitted from a diesel engine mainly consists of soot composed of carbonaceous matter and SOF (Soluble Organic Fraction: soluble organic matter) composed of high-boiling hydrocarbon components.
- SOF Soluble Organic Fraction: soluble organic matter
- a particulate filter is installed in the exhaust pipe through which exhaust gas flows. Has been done in the past.
- the particulate filter has a porous honeycomb structure made of a ceramic such as cordierite, and the inlets of the respective flow paths partitioned in a lattice are alternately sealed, and the inlets are sealed.
- the outlets of the flow channels and the flow channels are sealed so that only the exhaust gas that has passed through the porous thin wall that defines each flow channel is discharged to the downstream side.
- particulates are collected on the inner surface of the porous thin wall.
- the particulate filter Since the mesh that cannot be burned and removed due to the lubricating oil accumulates in the particulate filter, the particulate filter is appropriately removed and directly cleaned by air cleaning, water cleaning, or the like. It is necessary to replace the particulate filter with a new one, and it is necessary to make the particulate filter detachable from the muffler.

- the muffler casing has a temperature sensor located away from the particulate filter, even if a temperature sensor is installed through the muffler casing. The temperature of the exhaust gas in the silencing space had to be detected as a substitute for the temperature of the exhaust gas flowing directly into the particulate filter.
- combustion control is performed on the engine side to actively burn and remove the particulate matter collected by the particulate filter, and the exhaust gas temperature is increased by post-injection after-fuel injection. Even if it does, the exhaust gas temperature directly flowing into the particulate filter cannot be accurately detected, and there is a problem that it is difficult to perform the combustion control on the engine side more precisely and accurately.
- the combustion control on the engine side is supplementarily described. If the post-injection is executed at a non-ignition timing later than the compression top dead center and unburned fuel is added, the added fuel is added. Is oxidized on the oxidation catalyst supported on the particulate filter (or on the oxidation catalyst if an oxidation catalyst is separately arranged in front of the particulate filter), and the heat of the reaction causes the catalyst bed of the particulate filter to react. The temperature will be raised to encourage burning out of particulates.
- the fuel by the after-injection is difficult to be converted into output, and combustion at the timing lowers the thermal efficiency of the engine, thereby reducing the power fuel.
- the calorific value of the fuel the amount of heat that is not used for power increases, which raises the exhaust gas temperature and promotes the burning and removal of particulates.
- the present invention has been made in view of the above circumstances, and has as its object to accurately detect the temperature of exhaust gas directly flowing through a particulate filter built in a muffler. I have.
- the present invention is an exhaust gas purifying apparatus in which a muffler in the middle of an exhaust pipe incorporates a particulate filter, and a concave portion is provided at a temperature detection point in a casing of the muffler to a position close to the particulate filter in the casing. And a temperature sensor is provided at the deepest portion of the concave portion.
- the temperature sensor is disposed in close proximity to the particulate filter in the casing, and the temperature sensor of the temperature sensor is located at the central portion of the entrance end face or the exit end face of the particulate filter.
- the recess may be formed in a cup shape, and an operation space for operating a tool for attaching and detaching the temperature sensor may be secured around the penetrating portion of the temperature sensor.
- the operation space secured in the recess is used to easily operate the tool and easily attach and detach the temperature sensor. It is possible to do it.
- An operation space in which a tool for attaching and detaching the temperature sensor can be operated can be secured around the penetrating portion of the temperature sensor, whereby the tool can be operated without difficulty and the deepest portion of the concave portion can be operated.
- the attachment and detachment work of the temperature sensor with respect to can be easily performed.
- FIG. 1 is a partially cutaway perspective view of an embodiment of the present invention.
- FIG. 2 is a cross-sectional view of the muffler of FIG. 1 in a side view.
