Some Recent Results Concerning the Reduction of Pollution by the Stratified Charge I. F. P. Process 650148
This paper describes the reduction in observed unburned exhaust products when a spark ignition engine is operated with the I.F.P. process of variable mixture strength.
The principle of the process is first explained; then the influence of the mixture strength on carbon monoxide and hydrocarbons in exhaust gases is shown. A comparison of normal carburetion processes and I.F.P. process, based on a stratification of the intake gases, shows how the extension towards the lean mixtures of the limit of the mixture strength results in the reduction of unburned products in the exhaust gases.
