20110239992Engine Control System For An Aircraft Diesel Engine - In an engine control system for an aircraft diesel engine for a propeller aircraft for controlling the injection valves, charge pressure valves, common rail pressure valves and propeller control valves actuated by non-redundant actuators, comprising a plurality of sensors and a regulating device connected thereto and to the actuators, two engine control units—first and second—which are each connected to a first and a second power supply and are each connected to the sensors, are provided and are interconnected by way of a serial bus and can be connected selectively to the actuators by way of relays that are supplied with power together with the first engine control unit. The two engine control units each have a diagnostic function for calculating the respective health levels (A and B), which are determined by the defects detected, can be exchanged by way of the serial bus and are compared to one another. If the health level (A) of the first engine control unit is below the health level (B) of the second engine control unit, the power supply to the relay is interrupted, so that the second engine control unit is automatically connected to the actuators by way of the relays that have released, and consequently a redundant engine control system for an aircraft diesel engine is created. The core of the invention is the automatically switchable connection of the two engine control units communicating with one another via relays depending on the calculated health level.10-06-2011

20110186007Method For Operating A Self-Compressing Aircraft Engine - Diesel engines are proposed as the drive unit for aircrafts that operate reliably and trouble-free even at great altitudes, wherein the combustion in the diesel engines at top dead center is moved up to an earlier point in time according to the flight altitude and the corresponding barometric pressure. In addition, the charge pressure may be set to a constant value, which is not dependent on the flight altitude, and furthermore, the quantity of fuel supplied may be adjusted to a minimum fuel quantity adjusted to the respective charge pressure.08-04-2011
