[0035] Research has found that a large number of single-cylinder diesel engines on the market have their idle speed adjusted when they leave the factory. Users often have different requirements for the idle speed after purchasing and need to adjust it themselves. The adjustment process requires removing the gear chamber cover and adjusting the internal speed regulating slide or the gap between the flyweight and the speed regulating lever to achieve idle speed adjustment.
[0036] Based on the above research, the disclosed embodiment provides a single-cylinder diesel engine idle speed adjuster to solve the technical problem in the prior art that the gear chamber cover needs to be removed when adjusting the idle speed, which causes complicated adjustment.
[0037] The defects existing in the above solutions are the results obtained by the utility model inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the utility model inventor to the present invention during the disclosure process.
[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0039] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.
[0040] As Figure 1 and Figure 2 shown, during the normal working process, when it is necessary to adjust the output of the single-cylinder diesel engine, the operator drives the speed-regulating connecting rod 2 to rotate around the connection with the housing bearing of the single-cylinder diesel engine, synchronously driving the idle-speed adjuster 1 fixed on the speed-regulating connecting rod 2 to rotate. The speed-regulating screw 4 is fixed at the connection between the speed-regulating connecting rod 2 and the housing of the single-cylinder diesel engine through the speed-regulating nut 5. At this time, the speed-regulating screw 4 deflects following the speed-regulating connecting rod 2, and then pulls the driven spring 6 at its end. As Figure 2 known, the other end of the speed-regulating spring 6 is connected to the strip-shaped speed-regulating arm 9. As the speed-regulating spring 6 pulls the speed-regulating arm 9, the speed-regulating arm 9 rotates around its connection with the speed-regulating rod 10, thereby driving the speed-regulating rod 10 to rotate, so as to change the intake air of the single-cylinder diesel engine and adjust the output of the single-cylinder diesel engine. After the speed-regulating connecting rod 2 is reset, the idle-speed adjuster 1 is reset, and one end face thereof abuts against the adjusting nut 8;
[0041] When the speed-regulating connecting rod 2 is not driven, the single-cylinder diesel engine is in the idle state. When the user needs to adopt different idle speeds according to the usage requirements, only need to manually rotate the adjusting nut 8 to rotate and move on the idle-speed adjusting screw 7, push the idle-speed adjuster 1 to make the idle-speed adjuster 1 deflect. When the idle-speed adjuster 1 rotates, it pulls the idle-speed adjusting spring 3, and through the idle-speed adjusting spring 3, pulls the speed-regulating screw 4 and the speed-regulating connecting rod 2 to deflect, thereby changing the intake air of the single-cylinder diesel engine and changing the output of the single-cylinder diesel engine in the idle state.
[0042] In the description of the embodiments of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0043] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, terms such as "first", "second" and other numerical terms used herein do not imply an order or sequence unless explicitly indicated in the text. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer or section discussed above may be referred to as the second element, component, region, layer or section.
[0044] Spatially relative terms, such as "inner", "outer", "below", "beneath", "lower", "above", "upper", etc., may be used herein to facilitate describing the relationship of one element or feature to another element or feature as illustrated in the figures. In addition to the orientation depicted in the figures, spatially relative terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as "below" or "beneath" another element or feature will be oriented "above" the other element or feature. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are to be interpreted accordingly.
[0045] Based on the above inspiration from the ideal embodiments of the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model.
