Abstract

The invention provides a middle plate for an engine adaptive outboard engine power compartment, which is characterized in that an integrated component (middle plate) capable of meeting the connection of oil, gas and water between an engine body and an oil pan (comprising a propeller lower assembly) is additionally arranged between the engine body and the oil pan, the engine body and the oil pan are selectively matched according to the difference of the power compartment when the outboard engine is in a type selection process, and the normal operation of the engine can be ensured only by redesigning an oil path, a gas path and a water path of the middle plate.

Description

Intermediate plate for engine adaptive outboard engine power cabin

Technical Field

The invention belongs to the field of piston engines, and particularly relates to a middle plate providing integration and conversion functions.

Background

Because the positions and the layouts of the reserved power cabins of the outboard engines produced by different manufacturers are different, the engines for various outboard engines need to be designed and arranged according to different outboard power cabins, so that the production cost is improved, and the research and development period is prolonged.

Disclosure of Invention

In view of the above, the present invention is directed to a middle plate for an engine-adaptive outboard engine power compartment, so as to solve the problem of adapting an outboard power arrangement of an outboard engine for an outboard engine.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

an intermediate plate for an engine adaptive outboard engine power compartment comprises an intermediate plate body, wherein one side of the intermediate plate body is provided with a structure in adaptive connection with an engine body, and the other side of the intermediate plate body is provided with a structure in adaptive connection with an oil pan; and the middle plate body is provided with an inlet and an outlet of an air passage, a water passage and an oil passage which are communicated with the engine body and the oil pan.

Furthermore, the intermediate plate body is provided with an engine body oil duct inlet for sucking oil in the oil pan into the engine body, an oil pan oil return port for returning circulated oil to the oil pan, an intermediate plate water inlet for sucking seawater from the outside, an engine body water inlet for sending cooling water into the engine body, and an exhaust port for mixing waste gas and waste water generated after one working cycle of the engine and discharging the mixed waste gas and waste water into the outside.

Furthermore, a plurality of threaded holes are formed in the middle plate body, and the machine body and the oil pan are connected through bolts.

Compared with the prior art, the invention has the following advantages:

according to the invention, an integrated component (the middle plate) capable of meeting the oil, gas and water connection between the engine body and the oil pan (including the lower propeller mounting) is additionally arranged between the engine body and the oil pan, so that the engine body and the oil pan can be selected and matched according to different power cabins when the outboard engine is in a type selection state, and only the oil circuit, the gas circuit and the water circuit of the middle plate need to be redesigned; the design requirements are better met, and through reasonable arrangement of oil, gas, water and bolts, different outboard engines can select proper engines according to the design of the power compartment without redesigning the engines.

Detailed Description

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

An intermediate plate for an engine adaptive outboard engine power compartment, as shown in fig. 1 and 2, comprises an intermediate plate body 2, wherein one side of the intermediate plate body 2 is provided with a structure adaptive to an engine body 1, and the other side of the intermediate plate body is provided with a structure adaptive to an oil pan 3; and the middle plate body 2 is provided with an inlet and an outlet of an air passage, a water passage and an oil passage which are communicated with the engine body and the oil pan.

Specifically, the intermediate plate body 2 is provided with an engine oil passage inlet 21 for sucking oil in the oil pan 3 into the engine body 1, an oil pan oil return port 22 for returning the circulated oil to the oil pan 3, an intermediate plate water inlet 25 for sucking seawater from the outside, an engine body water inlet 24 for feeding cooling water into the engine body 1, and an exhaust port 23 for mixing exhaust gas and waste water generated after one working cycle of the engine and discharging the mixed exhaust gas and waste water into the outside.

The middle plate body 2 is provided with a plurality of threaded holes, the middle plate body 2 is connected with the engine body 2 and the oil pan 3 respectively through bolts from top to bottom, and as shown in fig. 3, the whole structure is formed.

When the oil-return device works, the oil in the oil pan 3 is sucked into the engine body 1 by the intermediate plate through the engine body oil passage inlet 21 for cooling and lubrication, and the circulated oil is returned to the oil pan 3 through the oil pan oil return opening 22. The intermediate plate sucks seawater from the outside through an intermediate plate water inlet 25, and then sends cooling water into the machine body 1 through a machine body water inlet 24. After one working cycle of the engine is finished, the generated waste gas and waste water are mixed at the connecting pipe and are discharged into the outside through the smoke outlet 23.

In the whole operation process of the engine, the water path, the oil path and the gas path connect the engine body 1 and the oil pan 3 through the intermediate plate. Different outboard engines can be redistributed through corresponding water route, gas circuit, oil circuit of intermediate lamella according to the engine compartment of difference, make oil pan 3 and engine head carry out the adaptation can, reduce research and development cost, research and development cycle.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
