摘要: A combustible mixture of air and minute fuel droplets is produced for supply to the cylinders an internal combustion engine. This formed by accurately controlling both atomization mass flow rate over substantially entire operating range These controls are accomplished introducing liquid into a stream intake uniformly distributing in followed passing through constricted zone increase velocity sonic. The sonic at divides that entrained throughout stream. area quantity introduced adjustably varied correlation with demands imposed upon Downstream from zone, accelerated supersonic without imparting substantial turbulent thereto. Thereafter decelerated subsonic produce shock where believed be further subdivided distributed before supplied engine cylinders. velocities occur gradually increasing cross-sectional corresponding conical section having apex angle about 6* 18*. Operation such results reduced levels undesirable exhaust emissions, also permits operation high compression ratio engines on relatively low octane good power economy characteristics. Additionally, misfire does not even when operated lean air-fuel ratios.
