A/F and Liquid-Phase Control in LPG Injected Spark Ignition ICE 2000-01-2974

Many advantages are related to the use of LPG as fuel in SI injected ICE. Most of them regard the lower environmental impact with respect to gasoline.
The liquid-phase injection is one of the most important aspects of these engines, being able to guarantee the maintenance (and even an increase) of the more traditional engine performances (power, acceleration, driveability, etc) and to match the 3-way catalytic converter A/F specifications.
In this paper the transient phenomena occurring in an LPG injection system have been studied, focusing the attention on the problems related to A/F and liquid-phase control.
