Abstract
The utility model discloses a fuel electrical control rarefied burning device for energy-saving gasoline engine. Combustion quality is greatly higher than that of traditional combustion device, combustion efficiency is improved, instant fully combustion can be realized, combustion power can be increased, combustion time is shortened, and waste discharging is purified. The utility model comprises a fuel injection nozzle and an engine combustion chamber 8; the utility model is characterized in that the fuel injection nozzle is connected with a reinforcement gasification nozzle 2 for spraying of gasifying liquid in parallel, a gasifying cavity 7 is provided with a temperature sensor for gasifying cavity 3 and an electric heater 4 for gasifying cavity 4 inside, and the joint of an outlet of the gasifying cavity and a fuel intake valve of the engine combustion chamber 8 is provided with a one-way pressure valve 6.
Description
The utility model is mainly used in petrol engine, belongs to field of combustion technology.
Known petrolic firing chamber will be through the atomizing and two processes that gasify before burning, and gasoline is atomized into granule oil droplet state through oil nozzle or Carburetor, enters sucking pipe or firing chamber again and carries out heating and gasifying and burn.Owing to be subjected to the influence of factors such as heating-up temperature, it was of low quality to gasify, and fails during burning in short time perfect combustion when traditional firing unit gasified, and a large amount of heat energy do not make full use of, and just discharged with waste gas, caused the fuel oil waste.
The utility model purpose is to disclose the automatically controlled lean combustion device of a kind of energy-saving gasoline engine fuel, burning quality is far above traditional combusting device, improved combustion efficiency, can reach instantaneous perfect combustion, thereby increase burning explosive force, shortened period of combustion, pollution from exhaust emission is reduced.
The utility model includes oil nozzle 1, engine chamber 8; It is characterized in that entering gasification chamber 7 from an end of gasification chamber 7 with the reinforcement of oil nozzle 1 an injection caburation liquid in parallel gasification mouth 2, oil nozzle 1 and fogging oil/vapour of strengthening gasification mouth 2; At least one gasification chamber temperature transducer 3 respectively is housed inside and outside the chamber of described gasification chamber 7, gasification chamber 7 has one from the gasification chamber electric heater 4 of outer wall to gasification chamber 7 heating, and the fuel oil intake valve junction of the outlet of gasification chamber 7 and engine chamber 8 is equipped with one-way pressure valve 6.
The utility model also includes one after receiving transducing signals such as igniting that motor sends, throttle position, air mass flow, air temperature, the gasification mouth is strengthened in i.e. instruction, oil nozzle is program priority injection caburation liquid and jet atomization gasoline in gasification chamber in accordance with regulations, mix the back and form oil bag liquid status, carry out the ECU (Electrical Control Unit) 5 of heating and gasifying.With ECU (Electrical Control Unit) 5 supporting Air flow meter, intake air temperature sensor, throttle position sensor, engine rotation speed sensor, engine crankshaft corner sensor, engine temperature sensing unit, detonation sensor, the lambda sensor systems of being equipped with.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model electric control principle block diagram;
The gasification temperature of gasification chamber is realized heating and temperature control to electric heater by ECU (Electrical Control Unit) according to the temperature sensor signal that is arranged on the temperature transducer inside and outside the gasification chamber.
The utility model is a kind of innovative energy-saving type fuel injection system, is electromechanical integrated product.Owing to set up gasification chamber, be provided with the electric heater heating and gasifying outside the chamber.Gasification mouth injection caburation liquid in the chamber is strengthened in ECU (Electrical Control Unit) control during gasification, again by controlling fuel injection by electric control unit mouth jet atomization gasoline in the chamber.Strengthen the gasification liquid of gasification mouth ejection and the atomization gas of oil nozzle ejection and mix, form oil bag liquid status, thereby increased the area of contact of fuel oil and air.When the pressure of gasification gasoline in the chamber reaches the pressure of regulation, chamber inner end one-way pressure valve is opened, gasification gasoline enters in the firing chamber, carry out second gasification combustion, the burning quality of this device has improved combustion efficiency far above traditional combusting device, can reach instantaneous perfect combustion, thereby increase burning explosive force, shortened period of combustion, pollution from exhaust emission is reduced.The utility model atomizing and gasification are controlled by engine electric-controlled unit, when ECU (Electrical Control Unit) is received the igniting throttle position that motor sends, air mass flow, behind the transducing signals such as air temperature, the gasification mouth is strengthened in i.e. instruction, oil nozzle is program priority injection caburation liquid and jet atomization gasoline in gasification chamber in accordance with regulations, mix the back and form oil bag liquid status, carry out heating and gasifying, this device is that gasoline is before the engine combustion Indoor Combustion, set up by intelligent electric-controlled gasification reinforced device, strengthened gasification result, improved burning quality, accelerate and shortened period of combustion, reaching perfect combustion, thereby improved the thermal efficiency and engine power, is the development of gasoline electric-controlling injection system in modern age and perfect, reach lean combustion, aspect fuel-economizing, have important value.
