[0002] At present, there will be a gap on the face shield of the small engine to install the exhaust port of the muffler to discharge the exhaust gas. If the application mode of the engine changes and the position of the exhaust port of the muffler is required to be changed, it can basically be divided into rear exhaust port and side exhaust port. If there are two kinds of mouth, then the mask needs to be redesigned, and the mold needs to be re-opened, resulting in waste

Description
technical field [0001] The invention belongs to the technical field of motor vehicle accessories, and in particular relates to a dual-purpose engine mask, and also relates to a rear exhaust mask and a side exhaust mask used for the dual-purpose engine mask. Background technique [0002] At present, there will be a gap on the face shield of the small engine to install the exhaust port of the muffler to discharge the exhaust gas. If the application mode of the engine changes and the position of the exhaust port of the muffler is required to be changed, it can basically be divided into rear exhaust port and side exhaust port. If there are two kinds of masks, then the mask needs to be redesigned and the mold needs to be re-opened, resulting in waste. [0003] In order to expand the scope of use of small engines and reduce mold costs, if a kind of dual-purpose engine face cover can be developed, it can be applied to the two muffler installation methods of rear exhaust port and si...
