Ethan Brunet-Bailey Everything Leading Up to Nuclear Cars Engineering is why we have cars, electronics, and everything around us. The car that we have in 2016-2017 runs off of fossil fuels and some are electric. My goal for engineering in the next 150 years is to have a car that runs on the splitting of atoms. This will be a clean and reliable energy source for cars and will run for a long time and have massive benefits for the consumer. The car engines we use now function using what is basically a giant air pump. The spark plugs, gasoline, pistons, and everything else that is in the car work together to form the giant air pump. Air gets pumped into a tank and is filtered by the air filter then immediately mixed with fuel, either through a carburetor, or a fuel injection system.the air gets moved into a tank that gets mixed with fuel and creates a fire that allows this concoction to set on fire. The concoction of fuel and air gets pumped through the intake manifold, which is connected to the cylinder head. The cylinder head acts as sort of a gatekeeper between the intake and the combustion chambers. Most cars have four, six, or eight cylinders. If the cylinders all went off in sync, the engine would not run smoothly and wouldn t generate much power, so all of the cylinders are timed perfectly. In order for this to happen you need valves that need to open at a definite moment. In a car engine, these valves apply to the cylinder head, and they are opened and closed by the rotation of the camshaft, which then spins inside the engine, using oblong lobes to push the valves open. With its intake valve open, a cylinder is filled with a fuel mixture.
Then something is needed to distribute the spark to the combustion chamber. The cam shaft and the distributor work together and are connected by gears so that the distributor knows at all times which cylinder needs a spark. When the intake valve opens the distributor sends a spark through a spark plug wire to a spark plug. This makes a spark inside the cylinder, which causes an explosion. The explosion forces the piston downward, pushing it against the crank shaft, resulting in the crankshaft rotating. This rotation spins the transmission, which spins the drive shaft which spins the wheels making the car go. At highway speed the crankshaft will be spinning at a speed of about 3,000 revolutions per minute. http://usnews.rankingsandreviews.com/cars-trucks/best-cars-blog/2016/10/how_does_a_ Car_Engine_Work/ The way that I think the ocean powered engine will work is very simple. The car battery will be a strong and long lasting car battery so that it can pump about 12 to 13 volts of electricity into a container filled with ocean water. The ocean water reacts so that the particles from the salt and other particles in the ocean will turn into hydrogen and chlorine gas. The hydrogen gets pumped into the fuel tank of the car and gets pumped into the combustion chamber and then ignited with a spark from the spark plug. This will create an explosion that, if repeated several times every 10 to 15 seconds, all the way to maybe 40-50 times in between the explosions. It could go faster between explosions and can be controlled for how fast you want to go. This will be enough to turn the crankshaft and make the wheels turn. The more hydrogen getting pumped into the combustion chamber the faster the car will move because there is more force behind the explosion.
Nuclear cars will hopefully be a cleaner and safer way to improve the speed and make other aspects of the car run more smoothly. The combustion will be holding protons within as they spilt. When the protons split they make what is essentially a nuclear bomb inside of the combustion chamber. When the bomb goes off it will turn the crankshaft and make the wheels turn. With such a strong force behind the wheels it will save a lot of energy because people should be able to get across long distances with a single blast in the combustion chamber. Also if we can figure out a material that is affordable for most people and can contain a nuclear blast, people will save a lot of money on car parts that need to be bought and repaired because they won't be necessary to ignite the fuel. Stopping is a complication with this design but my idea implements a sturdy chamber that stops the explosion from getting to the crankshaft and also implements an emergency brake. The car would be dangerous with everyone going at such a high speed but we could use auto pilot technology so that accidents would be far less likely due to the removal of human error. These are my ideas for a cleaner and more efficient car engine. I think that these designs could help with profits also considering that some parts are not necessary. This however will take a while for the design to not be expensive to make. As the engines get cheaper and people start to rely on fuels that don t hurt the environment at all and if not very little. Many companies might start to make more money as well when the design is expensive. The big and major flaw with the nuclear design is that it is only going to work when everybody has a car that can reach those speeds. So we should stick with the other design. http://usnews.rankingsandreviews.com/cars-trucks/best-cars-blog/2016/10/how_does_a_car_en gine_work/
