| Question | Answer |
|---|---|
| In ft-lb per second, what is one horsepower? | 550 ft-lb per second. |
| What is the equation for piston displacement? | V=A*H |
| What is Cylinder Compression Ratio? | Comparison of volume TDC and BDC |
| what ignites the fuel/air mixture? | the spark plug |
| What is the stroke? | Distance from Top Dead Center to Bottom Dead Center. |
| What is in the mixture that is ignited in the cylinder? | Fuel and air. |
| What stroke-cycle is most used in aircraft? | Four- Stroke Cycle. |
| what type of horsepower does the engine make before any other factors withdraw power | brake horsepower |
| What is the optimal air to fuel mixture ratio? | 15 to 1 |
| what are the five events of the otto cycle? | induction, compression, ignition, power, exhaust |
| What does it mean if exhaust gases are blue? | Oil is burning in cylinders |
| What is Manifold Pressure? | The average absolute pressure of the air or fuel/air charge in the intake manifold and is measured in units of inches of mercury(Hg). |
| Who built the first successful Piston Engine working on a four stroke cycle in 1876? | Dr. N A Otto |
| what are the advantages of fuel Injection? | 1) No throttle plate ice 2)Uniform delivery of mixture to cylinders 3)More efficient than carburetors |
| Greater piston displacement equals | Greater maximum HP an engine can develop. |
| spark plug | ignites fuel mixture by means of a spark |
| What is Pre-Ignition? | Fuel/Air mixture is ignited in advance of the normal timed ignition |
| What is the most common internal combustion system? | Four stroke |
| What is the order or a four-stroke cycle? | 1, 3, 2, 4 |
| 1. An internal combustion engine is an engine in which mechanical energy is produced by | combustion |
| What are the strokes of a four-stroke engine? | Intake, Compression, Power, Exhaust |
| What is Detonation? | Fuel/Air mixture detonates after a normal timed ignition and explodes instead of burning smoothly. |
| What are the functions of the carburetor? | Vaporizes Gas to the cylinder using a venturi. Meter fuel air mixture. |
| The 4 purposes of the piston are to | Draw in fuel, Compress Mixture, Transfer power and Expel exhaust. |
