Problems solved by technology

The technical solution of this invention can make the valve swing arm not contact with the valve by the valve control device when the cylinder needs to be stopped, and the valve is always kept closed. However, the invention adopts electromagnetic drive, from normal opening to complete closing of the valve, which can be completed in one cycle. , there is no transition process, which increases the difficulty of engine load control

Embodiment Construction

[0017] This embodiment relates to an engine cylinder cut-off mechanism, such as figure 1 As shown, it includes a camshaft 1 arranged above the rocker arm 3, and a cam 2 arranged on the camshaft 1 to drive the rocker arm 3, and a rocker roller 32 which is rollingly fitted with the cam 2 is arranged on the rocker arm 3 , to reduce the wear between the cam 2 and the rocker arm 3, the rocker arm roller 32 is installed in the middle of the rocker arm 3 through the roller shaft 31, and the valve 9 connected to one end of the rocker arm 3 and driven by the rocker arm 3, the valve 9 A valve spring 10 for driving the valve 9 to return is provided on the top, and a valve spring 10 connected to the other end of the rocker arm 3 opposite to the valve 9 is used to push or pull the rocker arm 3 so that the rocker arm 3 is in contact with the cam 2 or separate actuators.

[0018] The structure of the executive body is as figure 2 and image 3 As shown, it includes a tappet 5 connected to...

Abstract

The invention relates to a motor fuel stratified injection mechanism. The mechanism comprises a rocker driven by a cam driven by a cam shaft as well as a valve connected with one end of the rocker and driven by the rocker; the mechanism also comprises an executing mechanism connected to the other end, opposite to the valve, of the rocker and performing pushing and traction on the rocker to enable the rocker to contact with or separate from the cam. The fuel stratified injection and restoring of the motor are realized by the controlling the contacting or separating between the rocker and the cam, the fuel stratified injection and restoring processes are stably transited, and the motor fuel stratified injection mechanism is simple in structure and is easily arranged on the motor.

Description

technical field [0001] The invention relates to an engine intake auxiliary mechanism, in particular to an engine cylinder cut-off mechanism. Background technique [0002] During urban driving, the engine is mostly in low-speed, small-load or low-medium load operating conditions. The gasoline engine uses the throttle to control the load. Under this load, the throttle is partially opened, and the pumping loss is very large, while the passenger car engine Most of them are multi-cylinder engines. At this time, if the combustion of some cylinders can be cut off, that is, the technology of cutting off cylinders is adopted to make the remaining combustion cylinders work under heavy load, and the throttle opening will be controlled to a large extent, thereby reducing the pumping loss. Improve engine fuel economy. [0003] For example, Chinese invention patent application CN103256124A discloses a valve control mechanism for an engine with deactivated cylinders in turn, which include...
