Abstract
The utility model discloses a diesel particulate filter (DPF) electric heating device with an air inlet adjustment valve. The device comprises an engine, an air inlet pipe arranged above the engine, an exhaust pipe arranged below the engine, an intercooler connected with the air inlet pipe, an air filter connected with the intercooler, an engine air inlet connected with the air filter, a particulate filter connected with the exhaust pipe, an oxidation catalytic converter connected with the particulate filter and an engine exhaust port connected with the oxidation catalytic converter, wherein the air inlet adjustment valve is arranged between the intercooler and the air filter; and an electric heater is arranged between the exhaust pipe and the particulate filter. As the engine is provided with the air inlet adjustment valve, and a high exhaust gas circulation (EGR) rate can be realized when the engine is at idle, so that the NOx emission when the engine is at idle is reduced, exhaust flow is greatly reduced, exhaust temperature is increased, and the requirement of a conventional electric heating regeneration technology on a high-power power supply is eliminated.
Description
Technical field
The utility model relates to a kind of DPF Electric heating appliance of bringing the gas modulating valve into.
Background technique
At present, traditional electric heating regeneration techniques is had relatively high expectations to electric power, generally needs 1.5kw-3kw.The electric heating regeneration techniques requires very high for power supply on vehicle, need to consume a large amount of electric energy, increased the burden of oil consumption and storage battery, cause easily that circuit is overheated and meet accident, the traditional electrical heating technology also often need be equipped with helping air supply system and exhaust gas bypass device, complicated operation.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can realize that very big EGR leads, and the NOx discharging when having reduced idling has reduced exhaust gas flow significantly, has improved the DPF Electric heating appliance of bringing the gas modulating valve into of exhaust gas temperature.
The utility model is achieved through the following technical solutions: a kind of DPF Electric heating appliance of bringing the gas modulating valve into, comprise motor, and be arranged on the suction tude of motor top, and be arranged on the outlet pipe of motor below, and the intercooler that is connected with suction tude, and the empty filter of connection intercooler, and the engine intake that is connected with empty filter, and the particulate filter of connection outlet pipe, and the oxidation catalyzer of connection particulate filter, and the engine exhaust port that is connected with oxidation catalyzer, be provided with the air inlet adjustment valve between described intercooler and the empty filter, be provided with electric heater between described outlet pipe and the particulate filter.
Further, be provided with cooler for recycled exhaust gas and EGR valve between described suction tude and the outlet pipe, described cooler for recycled exhaust gas is near suction tude one end, and described EGR valve is near outlet pipe one end.
Further, described particulate filter and oxidation catalyzer are the integral type setting.
The beneficial effect that the utility model is brought the DPF Electric heating appliance of gas modulating valve into is: because motor has the air inlet adjustment valve, during engine idle, can realize that very big EGR leads, thereby the discharging of the NOx when having reduced idling, reduced exhaust gas flow in addition significantly, improve exhaust gas temperature, overcome the requirement of traditional electrical thermal regeneration technology to large power supply.
