Definitions
- the gases used are mainly petroleum-based liquefied petroleum gas (LPG), a by-product of hydrogenation processes in petroleum refining, which consists essentially of propane and butane, and natural gas (CNG), which mainly consists of Methane is produced and obtained by extraction from natural gas sources. Since LPG and CNG contain no sulfur and lead compounds and have very good combustion properties with excellent mixture formation, pollutant emissions CO, HC, NO x and CO 2 are lower than in gasoline-only engines.
- LPG petroleum-based liquefied petroleum gas
- CNG natural gas
- Fuel still adequate lubrication of the valve seats can be achieved.
- the prerequisite for this is that distances and lengths of the intervals for supplying the first fuel type are selected such that, after the supply of the first fuel type has been discontinued, there is always sufficient lubricating action at the valve seats by the first fuel type.
- Intake pipe 5 in which a throttle valve 6 is included, gasoline is supplied to the gasoline injection valves 2.
- gasoline injection valves 2 are supplied to the gasoline injection valves 2.
- a cooler 7 is provided with water temperature sensor 8.
- the outline 9 of the motor vehicle and the wheels 10 are shown.
- the engine control unit 3 and the LPG control device 16 can likewise be integrated in a single control device, which is then programmed in a corresponding manner. LIST OF REFERENCE NUMBERS

Abstract
L'invention concerne un dispositif et un procédé pour faire fonctionner un moteur à combustion interne avec un premier et un second type de carburant. Le premier type de carburant présente un pouvoir lubrifiant suffisant pour les sièges de soupapes du moteur à combustion interne. Ledit dispositif comprend deux circuits de carburant associés au moins partiellement aux deux types de carburant, et au moins un dispositif de commande électronique qui commande le fonctionnement du moteur à combustion interne avec le second type de carburant. Le fonctionnement du moteur à combustion interne est commandé de telle façon que le premier type de carburant du moteur à combustion interne soit alimenté à des intervalles prédéterminés.
