In Holland (and most of Western Europe) mostly dual fuel systems are used. Even today´s modern systems start the engine on petrol, and switch over to LPG unnoticably once the vaporiser has warmed up. The vaporiser is plumbed in with the car´s cooling system. This works in cold climates too, although it might take running a few kilometers instead of a few hundred meters (like here) to heat up.
The latest technology is LPG liquid injection. Instead of vaporising the LPG, it is injected in the inlet manifold in liquefied form. This allows improved control of the fuel injection, which results in improved performance and optimum combustion. Because a liquefied petroleum gas system employs the original petrol engine’s computer, all the original characteristics are retained and the emissions are less harmful to the environment.
Holland and Italy are the home to the world´s leading LPG systems manufacturers, succesfully exporting their products across the globe.
