The utility model discloses an oil injection and recovery device of an electronically-controlled engine teaching system. The technical problem to be solved is to overcome the defects of the injected oil recovery method of the electronically-controlled engine teaching system in the prior art. The technical scheme adopted is as follows: the oil injection and recovery device comprises a mounting bottom plate, at least one common-rail bracket arranged on the upper part of the mounting bottom plate, a common-rail oil pipe connected with the common-rail bracket and equipped with an oil inlet pipe, an oil outlet pipe and at least one oil outlet nozzle disposed between the oil inlet pipe and the oil outlet pipe, oil injectors of which each is connected with one oil outlet nozzle, glass pipes of which each is connected with one oil injector, glass pipe supports of which each is connected with one glass pipe, a glass pipe support bracket connected with the glass pipe supports and fixed to the lower part of the mounting bottom plate, and needle valves of which each is connected with one glass pipe support and communicated with one glass pipe. The oil injection and recovery device is advantageous in that no mechanical part of an engine participates in work, so that work noise interference of the engine is avoided, and the work condition of electronic control components can be easily judged; and the device has neither fuel consumption nor exhaust gas pollution, and is more economical and environment-friendly.
