The invention provides an intelligent ultrahigh compression ratio engine, which comprises: the engine comprises an air pressure sensor, a softer spring light valve, a high-pressure oil nozzle, a hydraulic oil pump, an air sensor, an electromagnetic valve and a cam angle hydraulic adjustable device, wherein after the engine is started, an accelerator pedal position signal and an air sensor signal are input into a vehicle-mounted computer, the electromagnetic valve is controlled to feed oil and return oil after calculation to control the cam hydraulic angle adjustable device, the opening and closing time of the valve is further controlled by controlling the phase of a cam to achieve adjustable compression ratio, the air pressure sensor adjusts air inflow under high low air pressure through the vehicle-mounted computer, the softer valve spring is used for reducing pumping loss, and the engine can achieve rarefied combustion and compression ignition efficiency which are higher than that of an existing four-stroke engine and can reach 53%.
Drawings
For ease of illustration, the invention is described in detail by the following detailed description and the accompanying drawings.
FIG. 1 is a schematic diagram of the invention.
In the figure, 1-an accelerator pedal, 2-a vehicle-mounted computer, 3-an air pressure sensor, 4-an air sensor, 5-an electromagnetic valve, 6-a hydraulic oil pump, 7-a cam angle hydraulic adjustable device, 8-a softer spring light valve, 9-an ultrahigh compression ratio cylinder and 10-a high-pressure oil nozzle.
Detailed Description
In order that the objects, aspects and advantages of the invention will become more apparent, the invention will be described by way of example only, and in connection with the accompanying drawings. It is to be understood that such description is merely illustrative and not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
It should be noted that, in order to avoid obscuring the present invention with unnecessary detail, only the structures and/or processing steps closely related to the scheme according to the present invention are shown in the drawings, and other details not so related to the present invention are omitted.
The working principle of the specific implementation mode of the invention is as follows: the position signal from an accelerator pedal is transmitted to a vehicle-mounted computer 2, the signal fed back by an air sensor 4 of an air inlet determines whether an electromagnetic valve 5 feeds liquid in a forward direction or a reverse direction to control the phase of a cam angle hydraulic adjustable device 7 so as to control the opening and closing time of a softer spring light valve 8, the air quantity discharged by an air cylinder achieves the adjustment of the compression ratio of an ultrahigh compression ratio air cylinder, the air pressure sensor 3 feeds back the air pressure signal to the vehicle-mounted computer 2, the vehicle-mounted computer 2 corrects the air inflow of the air sensor through calculation so as to correct the compression ratio of the air cylinder, and a hydraulic oil pump 6 supplies hydraulic oil of the cam angle hydraulic adjustable device through the electromagnetic valve 5. The softer spring light valve 8 is to reduce pumping losses. The oil injection quantity of the high-pressure oil nozzle 10 is calculated and controlled by feeding back an action value of an air sensor to a vehicle-mounted computer signal.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may include only a single embodiment, and such description is for clarity only, and those skilled in the art will be able to make the description as a whole, and the embodiments of the present invention may be appropriately combined to form other embodiments understood by those skilled in the art.
