marine engines Flashcards
1
Q
- an engine that uses compression ignition
- an engine that uses heavy fuel oil
- an engine that does not use spark ignition
A
Diesel Engine
2
Q
a constant temperature cycle (a cycle based on the Carnot theory) that would require much higher compression than what is needed for compression ignition
A
Diesel Engine
3
Q
- a constant temperature cycle (a cycle based on the Carnot theory) that would require much higher compression than what is needed for compression ignition proposed by _____________ in 1892
A
Rudolf Diesel
4
Q
Who proposed the idea to compress the air so tightly that the temperature of the air would exceed that of combustion?
A
Rudolf Diesel
5
Q
- engine has four strokes in one combustion cycle
A
Four-Stroke Diesel Engine
6
Q
- where the air/fuel mixture is taken into the combustion chamber
A
Intake-Stroke
7
Q
- where the gases are squeezed by the momentum of the piston
A
Compression Stroke
8
Q
- where the spark plug fires and the gases are ignited
A
Power-Stroke
9
Q
- where the piston comes back up, pushing the spent gases out of the combustion chamber
A
Exhaust Stroke
10
Q
- Almost all automobiles and large motorcycles use ____________ engines
A
four-stroke
11
Q
- combines the intake and exhaust strokes into the power stroke from the four-stroke engine which requires only one stroke each of up and down to complete the cycle
A
Two-Stroke Diesel Engine
12
Q
- have fewer moving parts and shorter cycle which make them cheaper and able to run at high RPM
A
Two-Stroke Diesel Engine
13
Q
- unfortunately, also provide a lot more pollution because the lubricating oil gets mixed in with the fuel and air and gets burned and expelled
A
Two-Stroke Diesel Engine
14
Q
- a part of an engine in which combustion of an oil takes place
A
Cylinder Block
15
Q
- fitted on top of a cylinder block and its function is to seal the working end of a cylinder and not to permit entry and exit of gases on cover head valves of an engine
A
Cylinder Head
16
Q
- a shaft which transmits the power developed by an engine to the various parts of the vehicle
A
Crankshaft
17
Q
- connects piston to the cannon shaft and transmits the motion and thrust of piston to crank shaft
A
Connecting Rod
18
Q
- controls the opening and closing of valve at proper timing
- placed at the top of bottom cylinder
A
Camshaft
19
Q
- used to control the inlet and exhaust of the internal combustion cylinder
A
Valves
20
Q
- placed in the cylinder and transmits thrust to the connecting rod
- transmits power to the crankshaft
A
Piston
21
Q
- hardened steel parallel spindles fitted through the piston bosses and the end bushes or eyes to allow the connecting rods to swivel it
A
Gudgeon Pins
22
Q
- provides the good sealing fit and less friction resistance between piston and cylinder
A
Piston Ring
23
Q
- used in spark ignition engine
- fitted on the cylinder head and used to ignite the air fuel mixture inside the cylinder at the end of each compression stroke
A
Spark Plug
24
Q
- usually used in compression ignition engine
- sprays the fuel into comustion chamber at the end of compression stroke
A
Injector
25
Q
- its main function is to supply the air fuel mixture and collects the exhaust gases equally from all cylinders
A
Manifold
26
Q
- serves as the lubricating system
A
Crank Case
