    Abstract: PURPOSE:To improve consumption of liquefied petroleum gas (LPG) fuel and prevent the generation of knocking in an engine when gasoline fuel is used for the engine, by constituting a controller from LPG and gasoline fuel suppliers, fuel supply regulator and a variable compression ratio device. CONSTITUTION:When liquefied petroleum gas (LPG) is stored to a level above the prescribed amount in an LPG tank 8 under the low load operating condition, the signal of an AND circuit 26 opens the first opening and closing valve 15 and closes the second opening and closing valve 16, and LPG is fed to an engine 1 by the first fuel supplier 3. The signal of an OR circuit 29 is output to a variable compression ratio device 18, and the device 18 is controlled to be converted into high compression ratio operation, thus a fuel consumption characteristic is improved by LPG operation. At starting of the engine, a gate circuit 32 is closed, and the variable compression ratio device 18 is controlled to be converted into low compression ratio operation, causing the engine to easily start. When the engine is high loaded or a prescribed amount of fuel is not stored in the LPG tank 8, the signal of the AND circuit 26 is not output, opening the second opening and closing valve 16 and controlling the variable compression ratio device 18 to be converted into low compression ratio operation, and gasoline is fed by the second fuel supplier 4 to perform high output operation, improving the drivability. When a residual amount of fuel is short in a gasoline tank 12, LPG operation is performed in high compression ratio.

    Abstract: Embodiments described herein relate to systems and methods of operating internal combustion (IC) engines by combusting various fuel chemistries therein. Specifically, engines described herein can operate a wide range of fuel chemistries with varying molecular formulas. The chemical compositions of the fuels described herein make them more difficult to ignite than long chain hydrocarbons (i.e., fuels that include 6 or more carbon atoms in a molecule). In some embodiments, engines described herein can combust fuels that have the chemical properties of alcohols. In some embodiments, engines described herein can combust fuels that include hydroxide groups. Examples of such fuels include methanol and/or ethanol. In some embodiments, engines described herein can combust natural gas. These fuel chemistries are difficult to ignite, particularly at low temperatures and during initial engine startup. Systems and methods described herein address these ignition difficulties, particularly in diesel engine architectures.
