Supercharging apparatus for diesel and multifuel engines
Abstract
Abstract SUPERCHANGING DEVICE FOR A DIESEL ENGINE COMPRISING A COMBUSTION CHAMBER AND STARTING MEANS FOR THE TURBOCOMPRESSOR PERMITTING THE SAME TO OPERATE AS A GAS TURBINE. SAID TURBINE, STARTED PRIOR TO THE ENGINE, ESTABLISHES IN THE INTAKE MANIFOLD SUCH CONDITIONS, RELATIVE TO PRESSURE AND TEMPERATURE, THAT INITIAL IGNITION BY COMBUSTION BECOMES POSSIBLE WITH A LOW VOLUME RATIO. THE TURBINE CAN ALSO SERVE FOR STARTING THE ENGINE AND FOR DRIVING AUXILIARY SERVICES. AFTER THE STARTING OF THE DIESEL ENGINE, THE COMBUSTION CHAMBER OF THE DEVICE CAN BE SHUT DOWN. THE ENERGY NECESSARY FOR THE TURBO-COMPRESSOR, TO ENABLE IT TO FURNISH A SUFFICIENT SUPERCHARGING PRESSURE UNDER ALL OPERATING CONDITIONS, IS THEN OBTAINED BY MODIFYING THE CROSS-SECTION OF THE DISTRIBUTOR OF THE TURBINE. ONE EMBODIMENT OF THE INVENTION INCLUDES A REGULATING SYSTEM WHICH MAINTAINS THE SPEED OF ROTATION OF THE TURBO-COMPRESSOR AND THE SUPERCHARGING PRESSURE AT A CONSTANT VALUE.
