  • Internal combustion engine usable with a high vaporization heat fuel
    Patent number: 4522173
    Abstract: There is provided an alcohol internal combustion engine with direct injection and controlled ignition comprising a combustion chamber defined by a reciprocating piston and a flat cylinder head. The cylinder head supports a spark plug and an injector. In the dome of the piston is formed a cup disposed with respect to the intake valve so that the gases are set in rotation in the cup. The spark plug is placed in the cylinder head so that its electrodes are in the vicinity of the periphery of the cup where a rich mixture is produced by stratification at the end of compression. To further improve the stratification and the turbulence, favorable to complete and rapid combustion, a ramp may be provided around a fraction of the periphery of the cup.

  • Engine whose fuel is a product other than a petroleum product
    Patent number: 4216744
    Abstract: The invention relates to an injection internal combustion engine.The engine has a device for injecting fuel, preferably at high pressure, into the cylinder of cylinders, a device adjusting the injection advance in dependence on the load, and a controlled ignition device, the said engine being arranged to use a fuel other than a petroleum product, preferably an alcohol based product, and being characterized in that its dimensional characteristics are determined to supply a volumetric compression ratio between 12 and 20, preferably between 15 and 18 and in particular close to 16, and in that the device adjusting the injection advance is such that it supplies, at least for starting, a high value of advance, particularly of the order of 180.degree..
