#1 Pistons 2 25

The Operating Cycle use by most 4 stroke engines is known as the

• Benz Cycle

• Otto Cycle

• Diesel Cycle

• Brayton Cycle

Small piston engines used in aircraft ar usually

• Radial engines

• Inverted engines

• Horizontally opposed engines

• Inline engines

In an Otto Cycle engine, the ignition event occurs

• During the Power Stroke

• Before the Exhaust Stroke

• Just before the Power Stroke

• At the start of the Intake Stroke

Piston engine cooling is accomplished by two methods

• Liquid or Gas

• Air or Liquid

• Air or Oil Cooling

• Pressure and Vacuum

in order to improve the cooling of an air cooled aircraft engine this device is added

• Fuel/Oil heat exchanger

• Oil Cooler

• Belted Fan

• Radiator

This is used to adjust the amount of cooling air going through the engine

• Baffles

• Rubber seals

• Cowl Flaps

• Cooling fins

The engine component used to hold the crankshaft and other engine components is

• The Crankcase

• The accessory housing

• The cylinder base bolts

• The engine mount

The Crankshaft is usually made of

• Aluminum

• Bronze

• Steel

• Titanium

The Crankcase is usually made of

• Steel

• Cast Aluminum

• Wrought aluminum

• Composite materials

Crankshafts can be fabricated by this method

• Cast

• Forged

• Machined

• 3d Printed
