Propulsion Let’s explore the very basics of the types of engines and their systems
47
Reciprocating Engines
Internal combustion engine Converts chemical energy to heat energy to mechanical energy to drive propeller. Reciprocating action of pistons inside cylinders 3 ways to classify reciprocating engines Cylinder arrangement Cooling system type Lubricating system type
48
Reciprocating Engines
Cylinder arrangement Inline Even number of cylinders or all cylinders in a row. V Type Cylinders arranged in 2 rows or banks forming the letter "V" with an angle. Even number of cylinders.
49
Reciprocating Engines
Cylinder arrangement Opposed or O Type Engines 2 banks of cylinders directly opposite each other. Vertical or horizontally mounted. Most widely used in general aviation (GA). Radial Engines Consists of a row, or rows of cylinders arranged radially about a central crankcase. Odd number of cylinders 5, 7, or 9 per row. May have dual rows (9 cylinders in front and 9 in the back). Greatest drag of all cylinder arrangements.

52
Reciprocating Engines
Cooling system type Air cooled (fins around the cylinder) Very common Liquid cooled (radiator) Lubricating system type Wet sump system Entire oil supply is carried in engine. Example car engine. Dry sump system Independent oil system. Separate tank and tubing or hose to engine oil pump.
53
Reciprocating Engines
Most of the reciprocating engines used today are 4 stroke engines. 5 events of a 4 stroke engine in the order of occurrence. Intake Compression Ignition Power Exhaust

Reciprocating Engine Components
Crankcase Section Foundation of engine One piece or multi-piece construction Cylinder Two main parts of a cylinder are Cylinder head Intake and exhaust valves 2 spark plugs Cylinder barrel Connected to cylinder head and crankcase Pistons move up and down in the cylinder Has compression rings and oil ring

57
Powerplants Reciprocating Engines
1. The intake stroke begins as the piston starts its downward travel. When this happens, the intake valve opens and the fuel/air mixture is drawn into the cylinder. SUCK, SQUEEZE, BANG, BLOW.
58
Powerplants Reciprocating Engines
2. The compression stroke begins when the intake valve closes and the piston starts moving back to the top of the cylinder. This phase of the cycle is used to obtain a much greater power output from the fuel/air mixture once it is ignited. SUCK, SQUEEZE, BANG, BLOW.
59
Powerplants Reciprocating Engines
3. The power stroke begins when the fuel/air mixture is ignited. This causes a tremendous pressure increase in the cylinder, and forces the piston downward away from the cylinder head, creating the power that turns the crankshaft. SUCK, SQUEEZE, BANG, BLOW.
60
Powerplants Reciprocating Engines
4. The exhaust stroke is used to purge the cylinder of burned gases. It begins when the exhaust valve opens and the piston starts to move toward the cylinder head once again. SUCK, SQUEEZE, BANG, BLOW.
61
Powerplants Reciprocating Engines
The four-stroke cycle takes place several hundred times each minute. In a four-cylinder engine, each cylinder operates on a different stroke.
62
Powerplants Reciprocating Engines
Continuous rotation of a crankshaft is maintained by the precise timing of the power strokes in each cylinder. Continuous operation of the engine depends on auxiliary systems, including the induction, ignition, fuel, oil, cooling, and exhaust systems.
63
Powerplants Reciprocating Engines
The intake/exhaust valves, spark plugs, and pistons are located in the cylinders. The crankshaft and connecting rods are located in the crankcase. The magnetos are normally located on the engine accessory housing.
64
Reciprocating Engine Systems
Intake system Must allow the proper amount of clean air to enter the engine at all operating conditions. Normally aspirated (nonsupercharged). May be supercharged. Supercharger driven by engine Turbocharger (driven by exhaust gases). Carburetor heat system prevents ice from forming. Alternate air valve is used to select heat or no heat. 14 CFR Part 23 each reciprocating engine air induction system must have a means to remove and eliminate ice.

Components Ignition Switch in flight deck Controls left or right ignition systems, both, or shutoff. Magnetos (2 separate or dual in one magneto housing) Self‑contained magneto which supplies the electrical energy for the ignition system. Once engine starts, magnetos do not need an aircraft battery. Coils – step up electricity (step up transformer) May be located inside magneto or separate for each spark plug. Distributor – distributes spark to spark plugs. Spark plugs – two plugs per cylinder.

Questions / Comments
76
Turbojet Engine Manufacturers usually have core sections
Compressor Combustion Turbine Compressor (2 basic types) Axial flow (Air travels parallel with axis of rotation) Centrifugal flow Auxiliary Power Unit (APUs) Combustion Section Provides for proper mixing of fuel‑air mixture. Located between compressor and turbine section. Fuel added to air creates heat energy. Turbine Section Extract kinetic energy from expanding exhaust gases. Drive compressor section.
