Abstract

The invention belongs to the technical field of engines, and particularly relates to a bath heating mixer and a heating method thereof. The bath heating mixer comprises a mixer body, a fuel gas connector, a waste gas connector and a bath heating plug, a mixing cavity is formed in the mixer body, and an air inlet communicated with the mixing cavity is formed in the mixer body; the fuel gas connector communicates with the mixing cavity; the waste gas connector communicates with the mixing cavity; a bath heating cavity is formed in the mixer body in the circumferential direction of the mixer body, the bath heating cavity is located in the outer side of the mixing cavity, and a bath heating medium is arranged in the bath heating cavity; and the bath heating plug is arranged in the bath heatingcavity and used for heating the bath heating medium. According to the bath heating mixer, the bath heating plug is used for heating the bath heating medium, so that the mixer is rapidly heated in a cold environment to improve the cold starting performance of an engine, and meanwhile, when the temperature of mixed gas is low, the bath heating plug is started to heat the mixer to ensure normal operation of the engine.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a bath heat mixer and a heating method thereof. Background technique [0002] With the implementation of the national motor vehicle national six emission regulations, it means that higher requirements are put forward for the engine emission standards. As a pioneer in the commercial vehicle market, natural gas engines are the first to implement the National VI emission standards. During the early research and development of natural gas engines, most engine manufacturers have chosen the EGR technology route. The exhaust gas in the EGR (English name: ExhaustGas Re-circulation, Chinese name: exhaust gas recirculation) system needs to return to the engine cylinder, and the exhaust gas needs to be pre-mixed with fresh air and natural gas before entering the cylinder. [0003] In the cold winter, because there is a large amount of moisture in the exhaust gas in the EGR syst...
