The device that can adjust the internal-combustion engine limited output power flexibly of the present utility model is to realize like this, comprise air feeder to the combustion chambers of internal combustion engines air feed, it is characterized in that air feeder comprises the house steward who is connected with combustion chambers of internal combustion engines, cool air is in charge of, hot air is in charge of, cooling unit, electric valve, filter, control gear, cool air is in charge of an end, hot air is in charge of an end and is connected with house steward by electric valve, cool air is in charge of the other end, hot air is in charge of the other end and is connected with filter, cooling unit is arranged between electric valve and filter, and the output of control gear control electrical signal links to each other with the input of electric valve electrical signal.During work, if will be when combustion chambers of internal combustion engines supply cooling clean air, by valve cool air being in charge of with house steward is connected, like this, cooling clean air through filter, cooling unit just enters combustion chambers of internal combustion engines participation burning, by improving the fuel injection quantity of internal-combustion engine, under the state that keeps ideal air-fuel ratio, the limited output power of internal-combustion engine is improved again; Under situations such as idling or brake, need be when combustion chambers of internal combustion engines supplying high temperature air, by valve hot air being in charge of with house steward is connected, like this, external world's cleaning natural air through filter just enters combustion chambers of internal combustion engines, under the state that keeps ideal air-fuel ratio, the limit lowest power of internal-combustion engine is reduced; In order to assist combustion in IC engine and disposal of pollutants management, guarantee to burn and in the ideal air-fuel ratio scope, carry out, can to supply the air of setting temperature by this device to combustion chambers of internal combustion engines, be in charge of the aperture and the cool air that are connected with house steward by valve control hot air and be in charge of the aperture that is connected with house steward, like this, the cabin of process filter cleans mixing air outward and enters combustion chambers of internal combustion engines participation burning with the temperature of setting, can reach and guarantee that each burning all can carry out with perfect condition, accurately adjust output power to satisfy, accurately control requirement such as disposal of pollutants.The present invention is owing to be provided with that cool air is in charge of, hot air is in charge of, like this, and just can be rapidly and optionally control clean air to combustion chambers of internal combustion engines supply setting temperature and then accurate controlling combustion engine output power.
Here, for promote hot air be in charge of in the temperature of clean air, hot air is in charge of and is arranged on behind the combustion in IC engine by the blowdown piping, is provided with for convenience, filter has two covers, is in charge of with cool air respectively, hot air is in charge of and is connected.
Compared with the prior art the utility model has and can carry out hot and cold conversion rapidly, can improve the limited output power of internal-combustion engine rapidly, simultaneously, can reduce the internal-combustion engine limited output power rapidly again.Has advantage simple in structure, that cost is low.Be used on the motor car engine, can significantly improve the Economy of fuel oil, improve output power, reduce oil consumption, reduce braking distance, reduce disposal of pollutants or the like beyond thought effect.Be used in other field of internal combustion engine class examination effect is also arranged.
