The document discusses the proliferation of plastics in internal combustion engines. It began when Henry Ford first used plastics for components like horn buttons and gears in his cars. Later, Matty Holtzberg experimented with plastic pistons and connecting rods and founded Polimotor to develop plastic-intensive engines using materials like Torlon, which can withstand high temperatures. The purpose is to reduce weight and improve fuel efficiency, with potential savings of 1-2% per 100 pounds reduced. However, some plastics emit gases that can irritate drivers.
3. Concept of plastic proliferation of cars was first invented by
Henry Ford.
For years Ford cars had been equipped with plastic horn
buttons, shift knobs, door handles and timing gears.
Ford was drawn to plastic for its cost- and weight savings
as well as its corrosion resistance.

4. After the Ford, Matty Holtzberg was the next
person who experimented on plastic car
components.
During the 1970s, he made and sold plastic pistons with
aluminium crowns to withstand combustion temperatures and
plastic connecting rods for racing engines.
In ’79, he founded Polimotor. (the name is shorthand for polymer
motor) to develop plastic-intensive engines.
The first Polimotor, a clone of the Ford Pinto 2.3-liter 4-
cylinder
5. Purpose of Proliferation:
a) Light weighting
The EPA says that for every 100 pounds taken out of the
vehicle, the fuel economy is increased by 1-2 percent. Based
on a gallon of gasoline costing $2.58, this translates to
savings of between $0.03-$0.05 a gallon. Of course, 100 lbs.
in a small hatchback is going to make a bigger difference
than those same 100 lbs. in aTahoe, so make reasonable
assumptions about what going lightweight can offer you.
6. weight data and fuel efficiency were
related as seen in Equation
η = a M-b + c
7. • For standard vehicles, efficiency equation is,
η = [ (3.01×107 ) / M2.140 ] + 4.54.
• For Hybrid vehicles, efficiency equation is,
η = [(2.21×103) /M0.545 ] – 12.03.

11. Plastics such as PVC, polypropylene,
polyurethane, ABS, HDPE,Torlon etc. And their
composites are generally used for this purpose.

17. • Test of strength: "Mr. Holtzberg campaigned a Lola
race car in the International Motor Sports Association's
Camel Lights series.
• race lasting up to five hours, the Polimotor engine
runs at 8,000 to 9,000 RPM. And theTorlon parts
don't melt.

19. Conclusion:
In this paper, the benefits of the composite
plastics in automotive industry were proposed. Various
composite plastics such as Torlon, ABS, these are used
for manufacturing various automotive parts such as door
knobs, car hood, bumpers. Henry Ford and Matty
Holtzberg were experimented and used the composite
Torlon in car engine. The engine so called as Polimotor.
Polimotor is a Polymer Motor.
Purpose behind the use Plastic engine is to reduce
weight and so increase the efficiency of the car. Also
there are some drawbacks of these engines. The main
drawback is that these engines emit some gasses which
cause irritation to the driver. Our on-going work focuses
on improving the composite plastic properties, which
will overcome the limitations of the present composites.
