Problems solved by technology
Because the ratio of the maximum working oil volume of the diesel engine to the starting oil volume is generally 2:3, the speed of the diesel engine is very low when starting, and the centrifugal thrust of the governor is very small and negligible. The speed regulating spring tensioned to the starting position only needs to overcome the limit. The thrust of the oil device spring, pull the speed control lever in the direction of fuel increase to make the oil limiter retreat to increase the starting fuel supply. Due to the structure of the oil limiter, when the tension torque of the speed control spring is balanced with the elastic moment of the oil limiter spring, This position does not necessarily reach the maximum oil supply position, and often limits the starting oil supply, resulting in difficulty in starting the diesel engine.
If the speed regulating device is not equipped with a fuel limiter, it will cause oversupply of fuel during normal operation, causing serious smoke and damage to the diesel engine

Embodiment approach
[0034] If the spring structure of the first embodiment is transformed into an elastic rubber member, the sixth embodiment is formed;
[0035] If the relative positions of the speed-regulating lever 1 and the speed-regulating sub-lever 2 of the fourth embodiment are reversed, that is, the speed-regulating sub-lever 2 is located inside the speed-regulating lever 1, thereby forming a Seventh embodiment of the inner side of the governor lever 1;
[0036] In the same way, if the relative positions of the speed regulating lever 1 and the speed regulating auxiliary lever 2 of the fourth embodiment are reversed, the eighth embodiment having a torsion spring structure and the speed regulating auxiliary lever 2 being located inside the speed regulating lever 1 is formed. Way.
[0037] Of course, there are other transformations, such as Figure 14-15 As shown, the torsion spring is placed inside the speed regulating lever shaft 3, the speed regulating lever 1 and the speed regulating a...

The invention relates to a speed regulator for a single-cylinder diesel engine, which comprises a speed-regulating lever, a secondary speed-regulating lever, a speed-regulating lever shaft, an elastic mechanism, a pin shaft, an adjusting arm, a speed-regulating spring and an oil limiter. Wherein, the adjusting arm is connected with the speed-regulating spring, which is further connected with a throttle operating mechanism; the adjusting arm, the speed-regulating lever and the secondary speed-regulating lever are looped on the speed-regulating lever shaft coaxially; between the speed-regulating lever and the speed-regulating lever shaft, a free rotating coupling is formed; the secondary speed-regulating lever and the speed-regulating lever shaft are fixedly connected through the pin shaft; the elastic mechanism is located between the speed-regulating lever and the secondary speed-regulating lever; on the secondary speed-regulating lever, a touch face is arranged; between the touch face and the oil limiter, a limit contact coupling is formed.
Description
Technical field [0001] The invention relates to a fuel supply control device for a diesel engine, in particular to a speed regulating device for a single-cylinder diesel engine. Background technique [0002] The previous single-cylinder diesel engine speed control device includes a speed control lever shaft, a speed control spring, a centrifugal speed governor, an oil limiter (oil quantity corrector) and a speed control lever for controlling the fuel injection pump. The working principle of this speed regulating device is: when the diesel engine is working normally, with the change of the speed and load of the diesel engine, the centrifugal thrust of the governor, the tension of the speed regulating spring and the spring thrust of the fuel limiter will change accordingly, so that the speed regulating lever changes to the new value. position and in a new equilibrium state, thereby adjusting the fuel supply of the fuel injection pump. Because the ratio of the maximum working ...
