GPF regeneration device for supercharged gasoline hybrid vehicle model and control method

Abstract

The invention discloses a GPF regeneration device for a supercharged gasoline hybrid vehicle model, a control method and a vehicle. The device comprises an engine, an intake manifold of the engine isconnected with a throttle valve and an intercooler through a first pipeline, an exhaust manifold of the engine is sequentially connected with a supercharger turbine, a three-way catalytic converter and a GPF particle catcher in series, the intercooler is connected with the supercharger compressor through a second pipeline, the supercharger compressor is connected with an air filter through a thirdpipeline, and a fourth pipeline is connected in parallel to the first pipeline between the throttle valve and the intercooler. The device is characterized in that an air inlet pressure release valveand a one-way valve are connected to the fourth pipeline in series, a heat conduction pipe is fixedly connected to the outer wall of the three-way catalytic converter, one end of the heat conduction pipe is communicated with the GPF particle catcher, and the other end is communicated with the fourth pipeline. The problem of regeneration of the hybrid vehicle model can be solved under the conditionof not influencing the performance of the engine.

Description

technical field [0001] The invention relates to the field of aftertreatment of automobile engines. In particular, it relates to a GPF regeneration device and a control method of a supercharged gasoline hybrid vehicle. Background technique [0002] Since the promulgation of the National VI emission regulations, the newly added particulate matter emissions from gasoline engines have become the focus of various OEMs. Most OEMs have adopted GPF under the chassis to deal with the emission of National VI particulate matter. However, while GPF solves particulate matter emissions, it also brings other problems. For example, hybrid vehicles cannot perform passive regeneration, and frequent active regeneration will lead to emission and drivability problems. In extreme cases in cold regions, GPF accumulates carbon too quickly and it is difficult to meet the active regeneration conditions, resulting in GPF blockage, frequent GPF lights or engine failure lights, causing complaints from ...
