Description
Technical field
The present invention relates to a kind of engine compresses gas concentration unit and method, particularly a kind of recovering device of the pressurized gas for the air hybrid power engine and method.
Background technique
In the working procedure of vehicle, inevitably there will be the situation of motor no-load running.Motor does not now produce power output, but needs to keep running state, and its piston is still in to-and-fro motion.Because piston can compress the γ-ray emission in piston cylinder when moving, if this compressed gas storage is got up and be back to use the opening/stop in the links such as control, low speed supercharging compensate and the compensation of car load pneumatic system air feed of motor, just can reduce oil consumption and the CO2 emissions of motor, can also improve the acceleration performance of automobile and reduce the situation of even eliminating over-emitting black exhaust while accelerating.The air hybrid power engine is exactly a kind of motor with this pressurized gas reuse technology.
Pressurized gas when realizing that motor is unloaded reclaims, and the pressurized gas recovering device need to be set on the air hybrid power engine.As shown in Figure 1, existing a kind of technological scheme is to increase a set of pressurized gas to store pipeline 100 on the air flue of motor, by single air flue compression gas concentration unit, makes pressurized gas enter into this pressurized gas and stores in pipeline 100.Particularly, the intersection's (being positioned at recovery window 102 places at suction tude 104 middle parts of motor) that stores pipeline 100 and engine air flue at pressurized gas arranges two reed one-way valves, one of them one-way valve is arranged on recovering mechanism one-way valve 103(motor in engine air flue when air-breathing, it is positioned at the upstream position that pressurized gas stores pipeline 100), another one-way valve is arranged on pressurized gas and stores the gas recovery approach one-way valve 105 in pipeline 100.When the motor normal suction, recovering mechanism one-way valve 103 is on state, and gas enters in motor from cylinder head suction port 101.Gas recovery approach one-way valve 105 has certain cracking pressure, and its force value, between suction pressure and exhaust pressure, stores pipeline 100 from the upper airway flow of motor to pressurized gas at the on state lower compression gas of this gas recovery approach one-way valve 105.During the motor normal suction, suction pressure (being generally less than 0.2MPa) is less than above-mentioned cracking pressure, thereby does not have gas and enter into pressurized gas and store in pipeline 100.In engine air flue under exhaust condition, what from the engine piston chamber, discharge is the pressurized gas with elevated pressures, its force value is enough to back down gas recovery approach one-way valve 105, recovering mechanism one-way valve 103 now, in closed condition, is stored thereby can make pressurized gas enter in pressurized gas storage pipeline 100.
Existing this pressurized gas recovering device is owing to having designed the one-way valve reed structure in intake duct, the one-way valve reed can block a part of circulation area in intake duct, reduced air inflow, thereby can affect the performance of motor, this reliability of structure is also poor simultaneously, when long-term the use, easily because reed is tired, causes leaking.
