LiquidSi is an LPG system that injects LPG in liquid phase directly into the engine. This results in higher performance and greater driveability than conventional LPG systems.

LiquidSi works well in extreme conditions. High or low temperatures, the autogas mix or humidity do not affect performance.

LiquidSi is maintenance friendly, can be installed on all modern multipoint gasoline engines, including turbo charged engines, lean burn engines and Euro5 engines. This results in an ultimately reliable system, giving you lots of driving pleasure and long-term fuel savings.
