Questions in this quiz (24)
1Q9. One of the main problems of the internal combustion engines is:
- AA. They are not powerful
- BB. The way to refrigerate them
- CC. They have never been used in aviation
- DD. None is correct
2Q10. One of the characteristics of star engines is:
- AA. All the cylinders are exposed to the air
- BB. Because of the A), cooling all the cylinders is easier
- CC. They normally use odd number ( to avoid deadtime in diametrally opposed cylinders)
- DD. All are corrects
3Q11. Two types of cylinder arrangements are:
- AA. In line and radial
- BB. In line and two-row
- CC. Only in line
- DD. Only radial
4Horizontal type of cylinder in line:
- AA. Are worse of vertical
- BB. Are better of vertical due to reduced length
- CC. Are less compact unit
- DD. They have more vibrations
5Q13. A great problem of vertical cylinder is:
- AA. The air that reaches the last cylinder is too hot
- BB. There is not any problem, they are easy to cool
- CC. None is correct
- DD. Vertical cylinders do not need to be refrigerated, they count with a heat radiation system
6Q14. The four-stroke cycle are:
- AA. Compression, power, intake and exhaust
- BB. Power, compression, exhaust and intake
- CC. Exhaust, intake, power, compression
- DD. Intake, compression, power and exhaust
7Q15. A way to aspiration in cylinders is:
- AA. Normally aspirated, that is called atmospheric
- BB. Supercharged/turbocharged
- CC. A) and B) are corrects
- DD. The only way of aspiration it is the atmospheric one.
8Q16. About the valve timing in Otto cycle:
- AA. Valves must open not exactly at TDC and BDC to improve the engine efficiency
- BB. Valves must close not exactly at TDC and BDC to improve the engine efficiency
- CC. Valves must open and close exactly at TDC and BDC to improve the engine efficiency.
- DD. A) and B) are correct
9Q1. Mark the wrong answer about ice formation on carburetors
- AA. Trottle / expansion ice: freezing of condensed water vapor of the air at or near the throttle
- BB. Static / adiabatic ice: when the ambient is very cold the carburetor can be frozen
- CC. Fuel / fuel evaporation ice: due to the cooling effect of the evaporation of the fuel
- DD. Impact / atmospheric ice: water in suspension in the atmosphere comes into contact with cold parts
10Q2. Carburetors work thanks to _______ effect
- AA. Venturi
- BB. Gravity
- CC. Coriollis
- DD. Magnus
11Q3. The numeration of cylindres in boxer engines:
- AA. Right cylinders are odd
- BB. It is established by the manufacturer
- CC. It is the same for all engines
- DD. Left cylinders are even
12Q4. Valves are made of...
- AA. Steel
- BB. Flexible material
- CC. Iron
- DD. Composites
13Q5. Name the different types of piston rings
- AA. Oil control, compression and oil scraper
- BB. Expansion and oil scraper
- CC. Oil control and oil scraper
- DD. None of them
14Q6. Types of pistons
- AA. Trunk pistons
- BB. Slipper pistons
- CC. Hammer pistons
- DD. A and B are correct
15Q7. What is the effect of holes in pistons?
- AA. It improves lubrication
- BB. It decreases combustion temperature
- CC. It improves refrigeration
- DD. A and C are correct
16Q8. Where do we find the sparks?
- AA. Crankshaft
- BB. Valves
- CC. Cylinder head
- DD. In the cone of the proppeller
17Q1. How does the injection carburetor work?
- AA. By pressure
- BB. By gravity
- CC. Both are right
- DD. Both are wrong
