Abstract
The utility model provides an intelligent blast chamber of a combustion engine, which comprises a cylinder, a working piston of the combustion engine, a cylinder cover, a seal cavity comprising the inlet valve of an inlet channel and the outlet valve of an outlet valve, and a burning control cylinder arranged on the cylinder cover and communicated with the seal cavity. The burning control cylinder is provided inside with a cooperating burning control piston and a piston rod connected with the burning control piston, a hydraulic element is connected with the piston rod, and the seal cavity is provided inside with a temperature-sensing piston and a pressure sensor. The volume and the shape of the blast chamber can be changed, which is propitious to highly effective and sufficient burning, remarkably decreases discharged harmful substance and increases the dynamic property and the economical efficiency of the combustion engine. The utility model is suitable for various spark-ignition and compression-ignition engines.
Description
Technical field
The utility model relates to a kind of firing chamber, particularly relates to a kind of internal-combustion engine intelligent combustion chamber.
Background technique
Traditional combustion chambers of internal combustion engines is the fixed volume Seal cage that is made of cylinder, internal combustion engine piston, cylinder head, intake valve and exhaust valve, all by load design commonly used.And in use regular meeting temperature, pressure, load, fuel etc. occur and changes, but because combustion chamber volume is constant, this just can produce high temperature malcombustion and high temperature unavoidably and pollute, or produces partial combustion and low temperature pollution during the little load of low temperature.And at present to generally adopting cylinder to regulate and control the method for burning outward in this kind firing chamber, very limited to the effect that solves partial combustion and pollution problem, can not adapt to the burning of different characteristic.
Summary of the invention
The internal-combustion engine intelligent combustion chamber that the purpose of this utility model is to provide a kind of volume of the bags and shape to change with combustion condition.
The utility model internal-combustion engine intelligent combustion chamber is to realize like this, it comprises the Seal cage that is made of intake valve in cylinder, internal combustion engine piston, cylinder head, the intake duct and the exhaust valve in the air outlet flue, and the control gas cylinder that is installed on the cylinder head and communicates with Seal cage.The control combustion piston that is mated is arranged in the control gas cylinder, and piston rod is connected with control combustion piston, and the hydraulic pressure components and parts are connected with piston rod, are provided with thermal transmitter and pressure transducer in the Seal cage.Wherein, the Seal cage that is made of cylinder, internal combustion engine piston, cylinder head, intake valve and exhaust valve is equivalent to traditional firing chamber.But the volume in sealing chamber generally should be less than traditional combustion chamber volume.That is to say, the intelligent combustion chamber is a seal space that is made of jointly cylinder, internal combustion engine piston, cylinder head, intake valve, exhaust valve and control gas cylinder and control combustion piston, and changes the volume and the shape in sealing space by the motion of control gas cylinder internal control combustion piston.During use, hydraulic pressure components and parts, control combustion piston, thermal transmitter all are connected with control box with pressure transducer and throttle.
The working principle of the utility model internal-combustion engine intelligent combustion chamber is, when the internal-combustion engine cold starting, import the electrical signal of control box into from throttle, thermal transmitter, pressure transducer, control combustion piston position and fuel etc., send integrated signal to the hydraulic pressure components and parts after control box is handled, hydraulic pressure components and parts application piston bar makes control combustion piston drop to extreme lower position.When internal combustion engine piston arrives top dead center position, intelligent combustion chamber volume minimum, and less than traditional combustion chamber volume, therefore, the temperature of the indoor mixed gas of intelligent combustion, increased pressure help the ignition burning of fuel; When the little throttle of low temperature (little load), the change of integrated signal makes hydraulic element will control the corresponding raising of combustion piston position, intelligent combustion chamber volume increases, but still less than traditional combustion chamber volume, so the indoor decapacitation of intelligent combustion keeps outside higher temperature and the pressure, can also reduce residual volume(RV), help abundant burning, make running steadily; When the high temperature maximum throttle, integrated signal reaches the hydraulic pressure components and parts, and the hydraulic pressure components and parts will be controlled the combustion piston and rise to the extreme higher position, this moment intelligent combustion chamber volume maximum, and greater than the traditional combustion chamber, temperature, pressure decrease, and can not produce Yin Wendu, overpressure and the malcombustion that produces.The detonation that occurs as ignition internal combustion engine, walk certainly, phenomenon such as surface ignition, or the soot that occurs of compression ignition internal combustion engine, noise etc.Because intelligent combustion chamber volume increases, increased air inflow simultaneously, significantly improved power and moment of torsion from face.
The advantage of the utility model internal-combustion engine intelligent combustion chamber is, variation by this combustion chamber volume and shape, the condition of various variations when satisfying burning, as the characteristic of fuel combustion, ignition method, temperature, pressure, engine load etc., help efficient, fully burning, significantly reduce harmful matter such as hydrocarbon, CO, NO
x, soot etc. discharging, improved the power character and the Economy of internal-combustion engine.Be applicable to the internal-combustion engine that uses each class A fuel A.Be particularly useful for rock gas, alcohols, biogas, hydrogen etc. and be difficult to get angry the internal-combustion engine of fuel.
