Three dimensional transient simulation of air-fuel mixture process in PFI gasoline engine;

The settlement way of ooze water of reduction gearbox in dry drawing machine is put forward,and the problem of oil mixing with water is resolved,so the lubrication efficiency is raised,the service life of gears,bearings and machine components are prolonged,the maintenance work is decreased,the oil and electricity power consumption are cut down.

For the demand of the cigarette process revamping the Automatic Controller,the spraying humidifier system by gas-water mixing reminds constant pneumatic and hydraulic pressure,achieves no piecewise linear adjustment.

Study on drag reducing theory and technique of oil-gas-water three-phase flow;
