TURBO-CHARGED INTERNAL COMBUSTION ENGINE

摘要

TITLE OF THE INEVNTION: TURBO-CHARGED INTERNAL COMBUSTION ENGINE A turbo-charged internal combustion engine having a torque characteristic adjusted to the torque hyperbola is provided and provides a substantially increased torque for a number of revolutions in the vicinity of zero and is characterized by a great output relative to the engine size. The internal combustion engine is provided with an auxiliary engine for a pre-charging blower that is connected in series to a charging blower driven by an exhaust gas turbine, and a primary engine. Both the auxiliary engine and the primary engine are in the form of a rotary piston diesel engine having a low compression and greatly differing respective outputs. The pre-charging blower is embodied as a volumetric compressor for providing a high start-up charge air pressure. A charge air pressure measuring device together with a charge air temperature measuring device is used for regulating the operational charge air pressure of the primary engine via an output control of the auxiliary engine. Further improvements of the output of the combusting engine are achieved by permanent glow plug ignition devices and continuously operating diesel fuel injection pumps. The internal combustion engine is especially suitable for directly driving a motor vehicle without a variable gear.
