Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0053] A method for controlling an engine valve spring, comprising: adjusting pressure to the valve inner spring 400 based on engine speed, adjusting the pressure of the valve inner spring 400 including adjusting an electrical control coupled to a lifter 700 . The valve inner spring 400 is a spring that is sleeved in an outer spring among the two return springs of the valve 200 .

[0054] Among them, such as figure 1 As shown, the valve inner spring 400 is sleeved...

Abstract

The invention discloses an intelligent control device which comprises a setting device connected with an electronic control unit (ECU), wherein keys for setting and a display area are arranged on the setting device; the keys comprise number keys, an enter key and a delete key; corresponding numbers are input by the digital keys to set a rotation speed working value of an engine; the vehicle-mounted ECU pushes a lifting device to a destination position according to an operation that the set rotation speed value of the engine contains the setting value and the set rotation speed value is adjusted to a magnetic absorber and a motor when a camshaft and a rocker arm are in a non-joint state; and the lifting device is retracted to a starting point position when the rotation speed value is less than the set value.

Description

technical field [0001] The invention relates to a gasoline engine, in particular to an adjustment method capable of changing the valve spring pressure according to the engine speed. Background technique [0002] The valve spring of the engine is the only part that guarantees the valve reset. If the valve spring force is too large, it will seriously damage the wear of the parts of the valve train. If the valve spring force is too small, the valve reset will lag behind, causing the valve and the power piston to collide. [0003] The return force of the valve spring is set according to the maximum speed of the engine to ensure the high-speed operation of the engine. However, the pressure of the valve spring at the highest speed is relatively large, which will inevitably affect the torque of the engine at low speeds. [0004] In order to achieve the reset speed of the valve in some high-speed engines, the valve spring adopts a double spring design, one inner spring and one outer...
