1. The Seminole is equipped with two Lycoming Powerplants
O-360 engines the right is a LO-360
Carburete
d4
Cylinder
Horizontally Opposed
Air Cooled
Naturally Aspirated
Direct Drive
2. Typically manufacturers will use fuel injected for multi Fuel
Injection
engine aircraft for a few reasons:
Better Fuel Flow
Faster Throttle Response
Precise Control of
Mixture Better Fuel
Distribution Easier Cold
Weather Starts
3. Ignition is provided from the magnetos redundan- cy
Magnetos are rotating magnets that provide the and better
spark to ignite the fuel air mixture performanc
Typically on the left magneto there is a feature e
called an impulse coupler Total of 16
The impulse coupler provides the initial spark spark plugs
when starting the engine 8 per each
Magnetos are independent of the electrical engine and 4
system except for engine starting per each
magneto
- The Seminole has two magnetos per engine
The reason there are two per each engine is

4. Turbochargers are common in multi engine -The
aircraft due to: Seminole
Higher cruising altitudes which equates distributes
to: Being above the weather electrical
Higher true airspeeds power
A turbocharger uses exhaust gases to drive a through dif-
turbine which drives an impeller ferent buses
The impeller boosts the induction air to a B
higher pres- sure, which makes it possible to a
achieve sea level en- gine performance at t
higher altitudes t
e
5. Typical small multi engine aircraft will utilize r
either a 14 or 28 volt direct current system y
Most manufacturers choose 28 volt systems
because there is less power loss through b
wiring u
D.C. systems are preferred over A.C. systems s
because they are simpler and lighter
A
- The PA-44 is equipped with a 14 volt electrical
v
system which is made up of
i
Push type circuit breakers
o
A 12 volt, 35 amp/hr battery
n
Two 70 amp engine driven belt driven
i
alternators Voltage regulators
c
Over voltage
s
relays
