Abstract: The fuel used, such as LPG, evaporates at raised temperature. It is proposed that when the internal combustion engine is not running a part of the fuel supply pipes should be heated, so that the liquid fuel therein evaporates. When injectors leak only vaporous liquid will then enter the combustion chamber.
Abstract: A pressure regulating system with amplifier is provided for preparing the mixture of a gas with air for a combustion engine. The pressure regulating system comprises a first and second inlet conduit opening in a first chamber through which gas is supplied under constant pressure. The first inlet conduit is separated from the first chamber by a valve connected to a diaphragm. The second inlet conduit comprises an adjustable restriction, through which a constant small quantity of gas being delivered to the first chamber. The pressure regulating system also comprises an outlet conduit being directly connected to the first chamber and to the inlet of the user and a second chamber being separated from the first chamber by said diaphragm. To said second chamber a third inlet conduit, provided with an adjustable restriction, is connected, through which a constant small quantity of gas is delivered to the second chamber. The second chamber is also connected to the first chamber i.e.

Abstract: An evaporating pressure regulating device is provided, more in particular for evaporating fuel of a combustion engine for both controlling the temperature and pressure of the fuel comprising an inlet conduit, a pressure reducing device and an outlet conduit. The outlet conduit comprises a heater/evaporator provided downstream of the reducing device, and the device further comprises a control member, a controllable injection member for liquid fuel provided downstream of the heater/evaporator and at least one temperature sensing device. The injection member is controlled by the control member. The temperature sensing device is setting the control member.
