Stratified charge fuel injection system for rotary engine

摘要

The improved stratified charge fuel injection system for a rotary engine has a fuel nozzle for injecting fuel into each engine working chamber coacting with an igniter at a common recess opening into the engine working chambers to ignite the fuel discharging from the nozzle. The improvement comprises heat retention means for the common recess so that the walls thereof become relatively hot and thereby promotes evaporation of the fuel discharging from the fuel nozzle.
