Embodiment 1

[0040] Embodiment one-to-one Figure 1~4 , the reference signs in the first embodiment include: oil passage A 1, oil passage B 2, oil passage C 3, oil passage D 4, oil passage E 5, oil passage hexa 6, oil passage G 7, oil passage Xin 8 , oil passage 9, box oil tank 10, box crankshaft hole 11, box balance shaft 12, box cover balance shaft 13, box cover oil tank 14, box cover crankshaft hole, oil pump 16, filter 17, box body 18 , Case cover 19, cylinder head 20, cylinder head cover 21, joint surface 22.

[0041] Oil passages are arranged on the engine casing 18, case cover 19, and cylinder head 20, and the oil passages are communicated by machining. The oil passes through the oil pump 16 and enters the filter 17 through the oil passage A 1. After that, the oil passage is divided into two branches. One branch is oil passage B 2. The oil passage B 2 is arranged on the tank cover 19. The oil passage B comes from the filter. 17 arrives at case cover oil groove 10, through the oil ...

Embodiment 2

[0044] Embodiment two corresponds to the attached Figure 5-7 , the reference signs in the second embodiment include: camshaft 1, limit boss 11, exhaust cam 2, intake cam 3, slider 4, bolt 41, counterweight 42, groove 43 in the middle of the slider , slide hole 5, push rod 6, stage clip 7.

[0045] Embodiment 2 includes all the content recorded in Embodiment 1, and also includes the following content. The camshaft is provided with an exhaust cam and an intake cam. The mechanism of this device is mainly located at the intake cam on the camshaft. It is in a C shape and hugged on the camshaft on the side of the intake lobe. The slider is located between the intake lobe and the limit boss 11 on the camshaft. The bolts that can be used for guiding pass through the slider up and down in parallel. side and camshaft, and fix the counterweight on the slider, because the bolt passes through the camshaft with a gap in the radial direction, under the guidance of the bolt, the slider can sl...

Embodiment 3

[0048] Embodiment three corresponds to the appended Figure 8-9 , The reference signs in the third embodiment include: support 1 , pin shaft 2 , rocker arm 3 , force end 4 , locking screw 5 , contact end 6 , pin shaft seat 7 , and screw hole 8 .

[0049] Embodiment 3 includes all the contents recorded in Embodiments 1 and 2, and also includes the following content. The rocker structure of this embodiment includes a support 1 and a rocker 3. The support 1 is a symmetrical structure. There are screw holes 8 to facilitate the fixing of the support 1 on the engine, and the two rocker arms 3 are symmetrically arranged on both sides of the symmetrical center line of the support 1, because the distance between the exhaust valve and the intake valve on the engine is usually greater than that of the push rod. The distance between them, therefore, the two rocker arms 3 are not parallel, such as figure 1 As shown, it is in an inverted "eight" shape, and the rocker arm 3 is an arc-shaped...

Abstract

The invention discloses a universal single-cylinder large-displacement gasoline engine device which comprises a box body, a box cover and a cylinder head which are connected with one another, wherein a crankshaft is in direct revolute-pair connection with the box body and the box cover; oil ducts communicated with one another are arranged on the box body, the box cover and the cylinder head; the oil ducts in the box body and the box cover respectively reach a rotation pair formed by the crankshaft, the box body and the box cover; a first branch oil duct and a second branch oil duct from which lubricating oil can flow out are arranged at the rotation pair; the first branch oil duct is communicated with an oil duct in the crankshaft to reach a crankshaft link; the second branch oil duct reaches the top of an air valve, a rocker arm and a push rod after being communicated with the oil duct in the cylinder head; and the oil ducts in the box body are simultaneously communicated with a balance shaft rotationally connected with the box body. The universal single-cylinder large-displacement gasoline engine device realizes diversification of universal engine products and remedies market shortage. More importantly, the universal single-cylinder large-displacement gasoline engine device can be used for completely replacing a double-cylinder engine with the same displacement. The universal single-cylinder large-displacement gasoline engine device is 30% lower than the double-cylinder engine in cost and can meet a hot market demand.

Description

technical field [0001] The invention relates to an engine. Background technique [0002] The crankshaft that rotates on the engine is connected to the engine piston by the crankshaft connecting rod. Simultaneously, as the common knowledge knows, the crankshaft drives the camshaft, pushrod and rocking arm in turn to drive the normal work of the valve. When the engine is in working condition, the movement speed of the piston is very fast, and the speed is very uneven, and other inertial forces cannot fully reach the equilibrium state, and the engine at this time vibrates. [0003] In order to eliminate the vibration caused by the crankshaft of the engine, adding a balance shaft is one of the methods. The balance shaft is actually a shaft equipped with an eccentric weight and rotates synchronously with the crankshaft. The reverse vibration force generated by the eccentric weight is used to make the engine obtain Good balance effect, reduce engine vibration, the balance shaft i...
