Abstract

The invention relates to the technical field of engine emission control, in particular to a device and method for preheating an engine and a catalytic converter at the same time and an automobile. Thedevice comprises a circulation loop, a controller, a timer, a first temperature sensor and a pressure monitor, wherein the timer, the first temperature sensor and the pressure monitor are connected with the controller; and the circulation loop comprises the engine, the catalytic converter and a heater, wherein the engine is connected with the catalytic converter through a pipeline assembly, the heater is arranged between the engine and the catalytic converter, and the heater is used for heating the engine and the catalytic converter at the same time under the control of the controller when aheating condition is met. According to the device and method, and the automobile, before the engine is started, the engine and the catalytic converter are preheated in advance at the same time, so that cold starting of the engine is avoided, the engine is easy to start, and the oil consumption and emission of the engine in the starting stage are greatly improved; and meanwhile the damage to supercharger blades 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 ...
