DA 40 D AFM
Airplane Description
7.9.7 TURBOCHARGER SYSTEM
The exhaust system contains a collecting line which collects exhaust gases from the outlets of the cylinders and leads them to the turbine of the turbocharger. Behind the turbine the exhaust gases are guided through the lower cowling to the exterior of the airplane. Excess exhaust gases bypass the turbine. The bypass is controlled by the ECU through the waste gate valve. A manifold pressure sensor behind the compressor allows the ECU to calculate the correct position of the waste gate valve. This prevents too high manifold pressures at low density altitudes. The intake air is compressed in the compressor which is driven by the turbine, and afterwards cooled down in the intercooler to increase power. Cooling the air increases efficiency through the higher density of the cooler air.

7.9.8 OIL SYSTEMS
The engine has two separate oil systems.
Lubrication system (engine and turbocharger)
The engine lubrication is a wet sump lubrication system. Oil is cooled by a separate cooler on the underside of the engine.
A dip-stick is provided to check the oil quantity through an inspection hole in the upper cowling. If required, oil can also be filled in there (for specified oil types refer to 2.4 -POWER-PLANT LIMITATIONS).
Gearbox and propeller governor system
The second oil circuit lubricates the gear and serves the governor system and the regulation of the propeller.
Gear oil quantity can be checked with the help of an inspection glass which can be reached through an inspection hole on the front side of the lower cowling.
CAUTION
If the gear oil quantity is too low, an unscheduled maintenance is necessary (for specified oil types refer to 2.4
-POWER-PLANT LIMITATIONS).

7.10 ELECTRICAL SYSTEM
Doc. No. 6.01.05-E Revision 3 26-May-2003 Page 7 - 39
7.10.1 GENERAL
The DA 40 D has 12 Volt DC system, which can be sub-divided into:
-Power generation
-Storage
-Distribution
-Consumers
Power generation
Power generation is provided by a 90 ampère alternator (generator) which is mounted on the bottom left side of the engine. The alternator is driven by a flat-belt.
The power output line of the alternator is connected to the 'battery bus' via a 100 A fuse, which is installed in the relay junction box mounted on the left-hand side of the firewall. The power output line also runs through the current sensor, which provides an indication of the power being supplied to the electrical systemby the alternator including the current for battery charging. The alternator has an internal voltage regulator which regulates the output voltage between 12 and 14 V. In the event of a main battery failure the field of the alternator is energized by a 12 V, 1.3 Ah sealed-lead-acid battery ('excitation'-battery) which is installed behind the instrument panel. The 'ENGINE MASTER'-switch connects the 'excitation'-battery to the alternator field via a 5 A fuse.
