Abstract

The invention relates to the technical field of engine emission control, in particular to a device, method and automobile for simultaneously preheating an engine and a catalytic converter. The monitor, the circulation loop includes the engine, the catalytic converter and the heater, the engine and the catalytic converter are connected through a pipeline assembly, the heater is arranged between the engine and the catalytic converter, and the heater is used for controlling The engine and the catalytic converter are heated at the same time; the invention avoids the cold start of the engine by preheating the engine and the catalytic converter before the engine starts, making the engine easier to start, and reducing the fuel consumption and emission of the engine starting stage. It is greatly improved, and at the same time, the damage to the supercharger vane is reduced.

Description

technical field [0001] The invention relates to the technical field of engine emission control, in particular to a device, a method and an automobile for simultaneously preheating an engine and a catalytic converter. Background technique [0002] With the increasingly stringent emission regulations and the development of new energy vehicle technology, more and more hybrid vehicles appear in people's lives. Since the hybrid electric vehicle is powered by the motor and the engine alone or together, when the engine is not used for a long time to start, due to: ①The low temperature inside the engine makes the fuel difficult to vaporize, and the mixture cannot be fully mixed; ②There is no oil film on the cylinder wall, which needs to be compensated ; ③Engine characteristics, low torque when the speed is low; therefore, it needs to be enriched. However, due to enrichment, the mixture will not be completely combusted, resulting in an increase in carbon emissions (CO, CH). At the ...
