The Prins Direct LiquiMax-2.0 system is used parallel to the standard fuel system for bi-fuel or mono-fuel operation. The Direct LiquiMax-2.0 system is a master-slave system.
The Direct LiquiMax-2.0 system is designed for engines with a direct fuel injection system. Direct Injection means that the fuel is injected under high pressure [20-200 bar] directly into the cylinder instead of injecting the fuel into the manifold (port injection). The Direct LiquiMax-2.0 system uses a modified high pressure fuel pump and fuel injectors of the petrol system to inject the liquid LPG under high pressure into the cylinder.
The Direct LiquiMax-2.0 alternative fuel system is equivalent to the original petrol injection technology and makes maximum use of the electronics and components already present. With the Direct LiquiMax-2.0 system the driver will experience no difference between driving on LPG or petrol.
Extensive research by Prins in cooperation with the Dutch university has shown that LPG fuel is a very suitable fuel in combination with a direct fuel injected engine. The motor efficiency by the use of LPG has increased significantly. This results in a CO2 reduction of an extra 10%. The increased engine efficiency is a result of the chemical and physical properties of LPG.
