Internal Combustion Cycle
Four cycle process
Intake
Compression
Expansion
Exhaust
Known as Otto Cycle
Developed by Nicolaus
Otto in 1876.
History of the V8 Engine
Automobile manuf. wanted more power.
Achieved by more cylinders.
A straight-8 was deemed too heavy and
long to fit in ordinary vehicles.
Led to the design of the V-shape, which
allowed for a greater power to weight ratio.
Our Model
The model used is a ¼
scale replica.
Features:
Operating Valves
Moving piston
Functional Fan
16 valve push rod
Cylinder Block
Most complicated part of
the engine.
Attaches cylinder heads,
crankcase, engine
mounts, drive housings,
engine ancillaries.
Made of Aluminum with
cylindrically bored holes.
Crankshaft
Translates linear
piston motion into
rotation.
Can be forged or cast
from iron
Connects to the
flywheel to reduce the
pulsation motion of the
four stroke cycle.
Camshaft and Valves
Cams force the push
rods to open and close
the valves.
Valves are used to
open and close the
intake and exhaust
ports in the cylinder
heads.
Design Improvements
Make the exhaust
manifold streamlined
for better flow of air.
Replace Push rod
system with Dual
Overhead Camshaft
system. (DOHC)
Difficulties
48 Valve/Rocker/Cam connections
Complex protrusions
Difficulties in measuring parts
Tolerances lead to difficulties in assembly
The number of parts made the animation
process slow and tedious
