Detailed Description
The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, but are intended to be covered by the appended claims in any way.
Referring to fig. 2, the utility model discloses a rotational speed sensor installation device of no bell housing engine, including camshaft end cover 1. The camshaft cover 1 is mounted on a camshaft hole of an engine block for sealing the camshaft hole. At least one lug boss 2 is arranged on the side surface of the camshaft end cover 1. Specifically, the number of the bosses 2 is two, so that the rotating speed sensor support 3 is stably and reliably mounted on the camshaft end cover 1. A rotating speed sensor support 3 is detachably mounted on the boss 2, and at least one sensor mounting seat 4 is arranged on the rotating speed sensor support 3. Specifically, the number of the sensor mounting seats 4 is two, wherein one of the sensor mounting seats is used for reading an engine rotating speed signal, and the other sensor mounting seat is used for inputting a rotating speed signal of an electronic speed regulating device of the oil pump. The end of the rotation speed sensor bracket 3 is provided with an upper dead point pointer 5 for indicating the corresponding scale on the engine flywheel 10. When the indication scale is 0 degree, the piston of the first cylinder of the engine is at the top dead center position; and meanwhile, the top dead center pointer 5 is also used for adjusting the ignition advance angle of the fuel injection pump of the engine, so that the engine is convenient and quick.
