초록 ▼

An internal combustion engine includes a moving piston within a combustion chamber that is temporarily divided into two zones when the piston is at and near its minumum volume position. Fuel is confined to a first zone where the fuel is ignited to generate combustion wave energy that drives gas within the second zone in Helmholtz resonance through a restricted passageway. Air from the second zone is periodically expanded into the first zone through the passageway to improve the combustion process in the first zone before the piston moves substantially away from its minimum volume position.

In an internal combustion engine including a movable piston in a variable volume combustion chamber having an effective diametrical dimension D and defined in part by fixed walls and in part by a working force of the piston, intake and exhaust valve means for controlling flow of charge and exhaust products to and from the combustion chamber; and fuel and air supply means for preparing and supplying a charge to the combustion chamber; the improvement comprising, said combustion chamber is configured such that, at and closely proximate the minimum combustion chamber volume position of the piston, the combustion chamber is effectively temporarily divided into an ignition chamber having a volume VA and a resonating chamber having a volume VB with a temporary restricted connecting passageway means between said chambers, said temporary passageway being effectively removed as the piston moves away from its minimum volume position, said passageway means having a length L measured along a line connecting VA and VB, an average transverse dimension g measured across its width approximately perpendicular to the length L, a cross-sectional area S at its transverse dimension g, and a volume VP of S×L; the ignition of each charge producing periodic combustion wave energy of frequency FA which travels near the speed of sound CA within said ignition chamber at approximately the autoignition temperature of the charge in said ignition chamber; said passageway dimensions g and L being arranged to quench flame propagation between VA and VB during substantially the time the piston is at and closely proximate its minimum volume position; said resonating chamber and passageway means arranged to constitute a Helmholtz resonator having a resonant frequency FB at the temperature extant in VB while combustion is occurring in VA, with FA and FB being approximately equal to each other; the maximum linear dimensions of VB and VP being generally less than ¼wavelength of FB at the temperature extant in VB during combustion in VA; said intake and exhaust valve means and said fuel and air supply means being arranged to establish a charge distribution in the combustion chamber such that, at the moment of ignition thereof, substantially all the fuel of the charge is in the ignition chamber and substantially only air with an insufficient amount of fuel to support work-producing combustion is in the resonating chamber; and the relationships between S, VB and L being defined as: [Figure] where (using metric units): k is a Helmholtz correction factor numerically between 0.6 and 0.85; L has a minimum dimension not exceeding the minimum dimension of g; g is nominally initially determined by assuming that the transverse dimension g of the passageway is uniform along its width and is related to D in accordance with the formula: g=0.1072D+0.1143 within the tolerance range of +0.050 cm. and -0.25 cm.; and FB equals K/D Hz, where K has a numerical value between 43,000 and 51,000.
