Engine oil adaptor component

The utility model relates to an engine oil adaptor component, which comprises an adaption seat and an engine oil filter fixedly assembled with the adaption seat. A connecting pipe, a first oil way and a second oil way are arranged in the adaption seat, the front end of the connecting pipe is provided with a first external thread section which is fixedly connected with an engine cylinder block to enable a main oil way to be communicated with a corresponding engine main oil way, and the front end face of the adaption seat is provided with a front communication groove which is used for communication with a corresponding cylinder block main oil way when the adaption seat is fixedly connected with the engine cylinder block. One end of the second oil way is communicated with the outside of the adaption seat while the other end of the second oil way is communicated with the front communication groove, and a front seal structure which is attached to and hermetically assembled with the corresponding engine cylinder block when the first external thread section is screwed into the corresponding engine cylinder block is arranged on the outer periphery of the front communication groove at the front end face of the adaption seat. By means of direct connection of the adaption seat with the engine cylinder block, most external pipelines can be saved, and accordingly the whole layout is more compact and the whole engine oil adaptor component occupies smaller space.
