- Give two examples and descriptions of products (and the companies
where they are produced) which are commercially available and directly related to the NCT
application your team has selected.
Mitsubishi Gasoline Direct Injection GDI Engine
The Gasoline Direct Injection (GDI)
system is the first attempt to use direct injection with gasoline, not diesel
fuel. It took 15 years to develop this compact engine, but in 1996 Mitsubishi
engineers Drs. Ando and Akira Kijima were finally able to present their GDI
prototype to the public. The difference between the GDI engine and the older
Otto-motors is that the fuel injection and mixing of gasoline with air take
place directly in the cylinder. This internal air/fuel mixture enables a more
exact regulation of the amount of fuel used. Since the GDI engine burns less
gasoline than carburetor engines and engines with indirect injection, it also
produces less CO2 and NOx. According to Mitsubishi, the new engine consumes 20
percent less gasoline and emits 20 percent less CO2, while its performance
increases by 10 percent. The GDI engine connects the advantages of standard
gasoline engines, quiet running and good performance,
with the advantage of a diesel engine, small consumption.
Mitsubishi is the first manufacturer to offer a gasoline engine with direct
injection in mass production and apply it to a variety of their new car models.
Approximately 37,000 GDI engines have been sold on the Japanese market so far,
and a car equipped with this new engine traveled 800 miles on only 17 gallons of
However, the NOx emissions did not meet the EPA requirements for the lifetime
of the engine in the U.S. market when this engine was first introduced. This
technology has been modified so that it meets the European Phase III regulations
that took effect in the year 2000, and which are similar to those of the U.S.
low emissions vehicle (LEV) standard.
TANAKA PureFire Engine
The PureFire engine is an engine
manufactured by TANAKAŠ Power Equipment Inc. that uses centrifugal force to allow
for more efficient fuel burning. It creates this centrifugal force through the use of
curved surfaces and high velocity fuel intake.

The curved surfaces come in two parts: the curved top and the U-shaped device on the
piston itself. The high velocity is created by using a smaller intake. In order for the
same amount of fuel to come in, the fuel has to come in faster. It is similar to putting
your thumb over a garden hose to make it spray water farther. As the fuel charge is
circulated through the crankcase it is prepared to maximize
atomization and be placed in "the optimum range of the spark plug for flame
propagation." (R Haslam)The curved dome contributes to
more efficient fuel burning by keeping the fuel separated in a smaller space. Thus
allowing the spark plug to ignite the high quality fuel completely and use the high
quality fuel to ignite the low quality fuel, in a chain reaction that leads to a cleaner,
more complete combustion. The U-shaped component also helps herd the fuel. The spark
plug is set at an angle to the piston, so it is easier to install and take out. With most
two stroke engines, having the spark plug in the center of the top would allow a more
complete ignition. This delivery design is a low cost alternative to fuel

The American Society of Mechanical
Engineers was founded in 1880 and is known today as ASME International. This nonprofit
educational and technical organization serves more than 125,000 members in almost 40
countries worldwide. ASME sets many industrial and manufacturing standards. ASME's members
work in all sectors of the economy, including government, industry, and academia.
ASME International's mission is to
promote and enhance the technical competency and professional well-being of its members.
Through quality programs and activities in mechanical engineering, ASME wants to better
enable its practitioners to contribute to the well-being of humans. ASME holds 200
professional development courses and 30 technical conferences each year.
As a member of ASME, one has
the opportunity to stay informed on new standards, inventions, and breakthroughs in
mechanical engineering. ASME also offers continuing education and training courses. They
offer a financial passport, which includes group insurance, auto and homeowner insurance,
and major credit card and banking privileges. Other benefits include discounts on car
rentals, receiving ASME's publication Mechanical Engineering, and
receiving discounts on mechanical engineering publications and journals.
ASME is involved with university
students majoring in mechanical engineering. Each year they try to recruit new student
members from the universities. ASME offers a membership discount of 50% to each
professional member who recruits a student. ASME offers grants and fellowships to graduate
students who are involved in cutting-edge research. ASME also offers scholarships and
loans to college students interested in a mechanical engineering degree.
Of particular importance to our project are the ASME student chapters located at the University of Central Florida, the University of Florida, the University of Miami, and one combined for Florida State University and Florida A & M
University. Also of importance to this project is that the Environmental engineering
Division of ASME has a few publications out citing the dangers of the chemical, MTBE. One
such publication is a letter to the EPA recommending that they take action on the MTBE
Also of particular importance to our project is the Internal Combustion Engine (ICE) Division of
ASME. This division was founded in 1921 to promote the art and science of mechanical
engineering of engines. This division encourages and fosters research and
development for mobile, marine, rail, generation, and stationary applications. ICE
has also summarized and published reliable data concerning these pursuits.
- Propose a new product or process based on the team's NCT
application, provide details regarding possible customer base, suggested retail price (per
unit) and projected sales of product for years 1 through 3.
Our proposed product is a two-stroke engine [CLICK here to see details]
that integrates the following three hamonized technologies. TANAKA's crankcase and
delivery system, mechanical logic gates, and a dynamic mechanical switch. to produce an
engine which has reduced emissions and fuel economy. Personal watercrafts, motorcycles,
snowmobiles, scooters, mopeds, small cars, and electric generators are all products that
would be improved if they utilized our engine. Our new engine would cost between $1500 and
$2000. The decline in jetski sales industry wide from 200,000 units in 1995
to about 70,000 units in the year 2000 would hopefully be reversed by the introduction of our product on the market.
This reversal in the trend would be attributed to the fact that many reservoir and other public waterways would be reopened
to personal watercrafts. Consumers would be interested in replacing their two-stroke
engine with our design because it is not only environmentally friendly but also more fuel
