CO2 Car

My CO2 car project.

1. Define the Problem

Create a CO2 car using White Box Learning

2. Brainstorming

3. Research and Generating Ideas


The most common power plant used in land transportation vehicles is the internal combustion engine. Internal combustion engines are used in the cars and trucks we use every day. These engines use a controlled explosion to create power. A four-stroke engine uses a piston and cylinder to draw fuel and air into the cylinder on its down or intake stroke. On the upstroke the air fuel mixture is compressed. At the top of this stroke, a spark ignites the fuel causing an explosion that forces the piston down, power stroke. When the piston comes back up the exhaust from the explosion is released. Hence the four strokes: 1) Intake, 2) Compression, 3) Power, and 4) Exhaust.


The guidance system provides information to the operator to help guide him/her to his/her destination. Speedometers in cars provide information about vehicle speed. Road signs help guide the driver by providing information about location and direction. Modern guidance systems are getting more sophisticated.


Accelerate, turn, stop - vehicles need subsystems to control motion. Throttle, steering and braking subsystems control the motion of land transportation vehicles. The throttle subsystem controls the power plant to increase or decrease speed. The throttle system provides the driver with a mechanism to control the amount of air-fuel mixture that enters the combustion chamber. This control allows the operator to accelerate or decelerate the vehicle by increasing or decreasing air-fuel mixture. For cars and trucks, the gas peddle provides this control.


The vehicle's chassis provides the structure that joins together the power, suspension, guidance and control subsystems. The chassis is designed to hold all of these subsystems while overcoming forces that could cause failure. Some of these forces include:

  1. Weight of the engine, suspension, people and cargo.
  2. Torsion or twisting forces created by the engine and drive train.
  3. Compression, tension, shear and torsion forces created by driving and road conditions (i.e. acceleration, deceleration, turns, bumps, potholes, etc.)
  4. Impact from accidents that could injure passengers.


The support subsystem is not part of a land transportation vehicle. Rather it is the components that provide the energy and infrastructure that keep vehicles operating. Cars need roads and maintenance for continued safe driving. They also need gasoline. As cars developed and improved, the infrastructure needed to support travel had to develop and improve as well. Road systems began to connect communities. Gas stations became frequent enough that great distances could be traveled.

4. Identifying criteria and specifying constraints

Materials List: Internet (

5. Exploring possibilities

6. Selecting an Approach

7. Developing a Design Proposal

9. Testing and Evaluating the Design, using specifications


10.Refining the Design

When I figured out about how much drag my cars had I shaped them out the most aerodynamic that I possible could and I also made it as light as I could without going against the criteria or constraints.

11. Creating or Making it

If I were to create this Co2 car as mass production then i would use cheap materials such as balsa wood, aluminum and laminating tube.
