ICE
# Term Definition
1 Diesel engines require a speed Governor
limiter, commonly called ______,
to control the amount of fuel
being injected into the Cylinder.
2 Define Bore The Diameter of the Piston Cylinder
3 What is the Highest point of TDC (Top Dead Center)
piston travel called.
4 This term is known as the Compression Ratio
amount of space within the
cylinder when the piston is at
TDC as compared to the amount
of space when the piston is at
BDC.
5 A cycle refers to: Any operation or series that repeats itself.
6 In a four-stroke engine, how 2
many rotations of the crankshaft
are required to complete one
cycle?
7 What are the four strokes in a Intake, Compression, Power, Exhaust
four-stroke cycle engine? (Must
be in order)
8 Define stroke. distance piston travels from TDC to BDC.
9 This term is the order In which Firing order
each cylinder fires in a
multi-cylinder engine.
10 In a two-stroke diesel engine, 1
how many revolutions of the
crankshaft complete one cycle?
11 What is "heat of compression" When compression reaches heat of approx.
1000 F
12 What are two types of engine Fixed, Flexible
mounts
,ICE
# Term Definition
13 what component is the mounting sub-base
pedestal for the engine and its
driven machinery, where
alignment Is critical.
14 If you sound a foundation bolt Tight
and it sounds clear like a bell it is;
Loose or Tight
15 what is the function of the oil pan collects and supplies engine oil
16 what are the two functions of the 1. Provides seal for cylinder bore and sleeves 2.
cylinder head provides structure holding for exhaust valves
the fuel injectors, and necessary linkages.
17 Define Crankcase Encloses the crankshaft and crankshaft
counterweights and directs returning oil to oil
pan.
18 what component is used to Rigid Mounts
prevent misalignment between
propulsion machinery and
propeller shaft
19 What are four reasons for 1. reusing a permanently compressed gasket 2.
cylinder gasket leakage improper instillation 3. Instillation of damaged
or defective gasket 4. improper torque of
cylinder head
20 what component is a barrel or cylinder liner
bore which provides the engine
with the cylindrical structure
needed to confine combustion
gases
21 what are the three types of 1. dry 2. wet 3. water-jacketed
cylinder liners
22 cylinder blocks are usually made cast iron
from
23 what are the three types of 1.Fixed 2. semi-floating 3.Full-floating
piston pins
, ICE
# Term Definition
24 Creates seal between piston and Piston Rings
cylinder wall and reduces friction:
25 Structure in place that works to Piston Skirt
keep piston in proper alignment
26 Prevents Full-floating piston pin Snap ring
from moving
27 Connects piston head to Piston Pin
connecting rod
28 allows connecting rod to rotate Bearing (Type used is Friction bearing)
with reduced friction around
crankshaft
29 holds bearing and connecting rod bearing cap
rod onto crankshaft
30 pistons are cooled by 1. lubricating oil 2.air through intake 3. ring
transferring heat through: contact with cylinder wall
31 what component is directly piston crown
responsible for changing the
volume of the cylinder
32 what are the two types of Conventional and Fork and Blade
connecting rods
33 what are the two functions of the Up-stroke- prevents metal to metal contact by
oil ring on Upstroke and distributing oil to cylinder wall. Down-stroke-
Down-stroke wipes excess oil from cylinder wall preventing
oil from burning in cylinder
34 convex, concave, and dome are Piston crown
terms for what part of the piston
35 what holds the rings in place piston grooves
36 what keeps the spacing between Lands
the rings
