摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine capable of performing stable combustion, in the large quantity EGR operation of the internal combustion engine having a cylinder injection valve (a direct injection valve).
SOLUTION: An auxiliary chamber valve 38 is opened for only a predetermined period when put in a state of generating burnt gas in a combustion chamber 40 in an expansion stroke. Thus, the burnt gas is shut up in an auxiliary chamber 36 and a communicating part 37. Afterwards, fuel is directly injected into the combustion chamber from a fuel injection valve 51 in an intake stroke or a compression stroke, and at the same time, the auxiliary chamber valve 38 is opened again. Thus, the burnt gas shut up in the auxiliary chamber and the communicating part is jetted in the combustion chamber, and the vaporization of the fuel is promoted, and a flow of gas in the combustion chamber is strengthened. As a result of this, the strengthened gas flow changes to strong turbulence of the gas in the latter period of the compression stroke, and the mixing state of the fuel and air is improved. A combustion speed is also improved by the turbulence of the gas. Thus, the stable combustion can be performed in high EGR operation.

摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine improving lean limit. SOLUTION: A conductive part 21 is put into contact with an intake valve 11 and an exhaust valve 12. The conductive part 21 is connected to a high voltage power source part 20, and the high voltage power source part 20 is connected to a connecting rod 5. The connecting rod 5 is electrically connected to a piston 4 via a connecting pin 6. Consequently, electric potential difference arises between a valve surface 14 and the piston 4 and electric field is generated when high voltage electric potential of different polarity is applied to the conductive part 21 and the connecting rod 5 respectively at the high voltage power source part 20. Consequently, corona discharge arises when fuel positioned in the electric field burns in combustion of fuel in a combustion chamber 10. Flame propagation speed is improved by corona discharge and combustion is promoted. As a result, lean limit can be improved. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a fluid injection nozzle which promotes atomization of fluid vapor. SOLUTION: A substantially disc-like fuel chamber 35 is determined by a tip surface 25a of a needle valve 25, an inner wall surface 31 of a valve body 30, and a surface 33 of an orifice plate 32 opposed to the needle valve 25. Projections 33a are projected from the surface 33, on an outer peripheral side of an orifice 34. Fuel is flowed into the fuel chamber 35, from a gap between an abutting portion 25c and a valve seat 31a, and struck against the projections 33a formed on the surface 33. The fuel is flowed between the projections 33a while being bent, so that turbulance is generated in the fuel flow. When the fuel containing turbulance is injected from the orifice 34, atomization is promoted in respect to the injected fuel vapor, by the energy of turbulance. Since the fuel vapor is thus easily mixed with air within a wide range for increasing combustion efficiency of fuel, it is possible to reduce poisonous matters discharged into exhaust gas and suppress fuel consumption.

摘要： PROBLEM TO BE SOLVED: To provide a liquid jet nozzle accelerating the atomization of fluid spray. SOLUTION: An almost disc-shaped fuel chamber 35 is formed by the leading end surface 25a of a needle valve 25, the inner swall surface 31 of a valve body 30 and the opposed surface 33 with the needle valve 35 of an orifice plate 32. Fine unevenness 33a is formed to the opposed surface 33 and the fuel flowing in the fuel chamber 35 from the opening part of a contact part 25c and a valve seat 31a impinges against the fine unevenness 33a formed to the opposed surface 33 to generate disturbance in the flow of the fuel. When the fuel including the disturbance is jetted from an orifice 34, the fine atomization of fuel spray is accelerated by the energy of disturbance. By this constitution, fuel spray is easily mixed with air over a wide range and the combustion efficiency of fuel is increased and, therefore, a harmful substance discharged into exhaust gas and fuel consumption can be reduced.
