The required size to race a CO2 car is is at least five feet eight inches tall and at least one hundred and forty pounds. Those are the minimum race car requirements.
Propulsion.
During the final stage of CO2 car production, finishing touches are added to the car, such as decals and paint. Quality checks are performed to ensure that the car meets performance standards. The completed CO2 car is then ready to race.
A CO2 car decelerates due to factors such as friction with the track surface, air resistance, and rolling resistance from the wheels. These forces act in the opposite direction to the car's motion, causing it to slow down.
Friction acts on all cars the same pretty much, model, rocket or tank. I am assuming this is a model race car though.The three important factors to look at are air resistanceRolling resistance (wheel to track and wheel to axle) I used to use no residue and no smell silicone dry sprayBody to track. How will the body of your car react if it touches the side of the track and can you use a Teflon coating? If not use the dry silicone spray and hope no one notices (it is cheating in most cases)Remember the old Nascar saying "If you ain't cheating, You ain't winning"
What is the distance used in a CO2 car competition What is the distance used in a CO2 car competition
the co2
Co2 cars arrived as early as 1947.. Douglas / Santa Monica plant engineers made and raced some of the first co2 jet cars for a little noon hour racing. Check out.. the Popular Science magazine issue Feb 1947 ( pages 102 & 103) for photos on this race. Some of the early co2 car kits were made by Monogram models in 1947/48 as well. There first co2 powered car kit was called the Hot Shot jet car. This was an instant hit, followed by the Terra jet, Aqua jet, Mono jet, and the Mid jet co2 car kits.
Petrol cars produce CO2 as a combustion by-product, so it might be said that whatever the fastest car in the world is the fastest CO2 car. There are no cars powered by CO2 - obviously - as any chemical reaction starting with CO2 needs energy to produce another substance. There might be a car somewhere powered by compressed CO2, but this will stop moving when it runs out of pressure. Consequently the fastest CO2 car is a parked car.
Aerodynamics of the car, the size of the wheels, the weight of the car, and the size of the CO2 cartridge.
Reducing mass and friction in a CO2 car can improve its overall speed and performance. With less mass to accelerate, the car can move more quickly, while reduced friction allows it to maintain momentum and travel farther. Both of these factors can help optimize the car's efficiency and competitiveness in a race.
