vFertile Question: Is petrol car or EV car more cost and eco friendly?


Intro: All of us have been in a car and most of us will drive a car in our lives! We are all aware that cars cause pollution and can be expensive to run!. Due to this we have asked the question; 'Are petrol cars or Electric Vehicle (EV) cars more cost and eco friendly? After much research our thesis is that the EV car is more economical and environmentally friendly. Due to the refuelling being cheaper & and that its contribution to the pollution of the Earth is less than as a petrol car. We will explain further in our report.




Who and when were cars invented?

The first true car was invented and perfected in the late 1800s in 1885/1886. It was made in Germany by Karl Benz with the help of Bertha Benz, his wife. She helped test out the car but was referred to as a motorwagen back in the 1800s and was the first person to drive a long distance of 106 km. Later on, they were outdone by Americans as they continued to dominate the automotive industry.

1837 – First American patent placed on an

electric motor

Thomas Davenport, a blacksmith from Vermont, is awarded the first American patent on an electric motor


How do EV operate?

When you press the accelerator pedal in an EV, The transducer connected to the pedal sends the position to the processor. An EV battery supply only directs current, So then it is further connected to the inverter. The inverter further converts the direct current into an alternating current. The power supplied to the motor is then converted into mechanical energy therefore running the car.




How do Petrol cars operate?


When the driver turns the key into ignition, the battery sends power to the starter motor which then turns the crank shafts and they get the pistons into motion. While the pistons are in motion they get the engine fired up and ticks over a fan. The fan then pulls in air via an air filter. The filter is so dirt and other stuff gets into the engine so then the filtered air can go into a chamber with the petrol or diesel. When they are both in the same chamber they become a fuel-air mix and then are stored in that chamber. Once the driver presses the accelerator, the throttle valve opens, the gas-air mix then goes through an intake manifold and is distributed through the intake valves, then into the cylinders. Through this whole process, the camshaft controls the opening and closing of the valves. The distributor in the car makes the spark plugs spark which then ignites the gas-air mix resulting in an explosion. The following explosion causes a piston to move down which then causes the crankshaft to rotate.



The pros and cons of an EV




The Pros of a EV

The first pro is that it looks like by 2050 most cars on the road will be electric. Another pro of the pros is for the environment because EVs have zero emissions and this means EVs don't have fumes unlike petrol cars. They don't have emissions because they only run on electricity/power. Another big pro is the low running cost. Their running costs are very low because they run on power. Meridian says filling up an EV is like paying $0.30 cents for a litre of petrol. A fun pro is the Acceleration time on EV cars because their motor is so much more simpler than an internal combustion engine. The power you are using can be renewed unlike fuel so you are using a renewable energy source so if we run out of fuel EV could still keep going till the battery dies. You don’t have to replace as many things as a petrol car because as we said before EV motors are simpler so there is less that can go wrong.


The cons of a EV

The main con of EVs are the distance before you have to charge them a normal EV can go about 100-150 km before needing a charge and this leads us into the next con and that is the time it takes to charge the car it takes about 6 hours with the slow charge and about 30 minutes with the fast charging but you need to have a 480V input into the charger and the average output of a wall plug is 230V but with a normal EV charger you can use a 230V plug which most people use to charge there EV. There are not as many charging stations when you're on the road because most petrol stations don't have EV chargers. When you have an EV your battery has limited use because a battery can just go forever. The battery will die and not die because it is out of charge. It dies because it has been for too long and this happens with EV barrarys. by far the most important con they are silent


What are the pros and cons of petrol cars


The pros of a petrol car

The distance that you can travel before having to refuel, unlike petrol cars you have to refuel them as often because the petrol car has a bigger fuel tank than a battery. From one full fuel tank the average car can go 640km now that is a lot more than an EV. another pro of petrol cars is that they can be so cheap to buy because there are so many of them and that is another pro you have so much choice for what to buy because they have been around for a longer time than EV there are so many different types of petrol cars and different types of modals you can get anything from a granny car that is small to a big truck and anywhere in the middle. And the most important thing is you can make a very loud raket when driving a petrol car.




The cons of a petrol car

The first con of having a petrol car is that you will be paying a lot of money to buy the fuel to power the car. So you will have to pay for the car then you will have to keep paying for it. Another con is what it does to the environment: the vapor that the petrol gives off is very harmful to the environment.



How do they gather the resources to power or fuel the cars?



Petrol cars


For petrol cars people use byproducts that are produced by fossil fuels that are extracted from the ground and then turned into gasoline that fuels many different vehicles from land, air, and sea. To collect Fossil fuels, people set up things known as oil rigs to collect them. When oil rigs are set up and ready to be used a thing called a casing which is a large diameter concrete pipe which lines up the hole so that it doesn’t collapse and allows the mud that is being drilled to circulate. Then what is known as the pump sucks mud from mud pits and pumps it into a thing called the drilling apparatus which is connected by pipes and hoses. Mud gets returned through the mud-return line from the hole. It then goes through the shale shaker to separate rock cuttings from the mud. After going through the shale shaker it goes through the shale slide which conveys all the rock cuttings into a place called the reserve pit, The reserve pit is there to store the rock cutting separated from the mud.


EVS


There are three main ways to recharge an EV, one is with electricity, two is with hydrogen but that's only if the EV has a vehicle hydrogen tank, and three is with solar power. For electricity, they use many different methods to generate it. Some methods include using turbines, coal mining and nuclear fusion. For turbines, they move a large magnet around a wire. That movement then conducts electricity into the wire that then goes into a generator. They use nuclear fusion by heating up water that will later produce steam, that steam will then drive the electricity. When you charge a car with solar power, they use the sun’s energy to convert into a power source for an EV.


Some E-cars use hydrogen gas to then convert it into electricity for a fuel source. Hydrogen gas is less harmful or dangerous than other flammable fuels. It also doesn’t hurt the environment because the only byproducts it releases are heat and water. Hydrogen gas has greater safety benefits than gasoline and natural gasses. So the fuel source for some E-cars are safer than gasoline or diesel as it is not as harmful as them.




What car is more cost efficient, e car or petrol run car?


EV


Nowadays to buy a EV it costs quite a bit more than getting a petrol car and this is because there are so many less EV compared to petrol cars and this is because they are newer and haven't been around for as long. Now the cost to run them is very cheap to run an EV and this is because it is run on power and as we said before 1 full charge for an EV is about $3.00 for 100km. So this means it costs more to buy but you can pay it back with the money you would have spent on fuel with a petrol can. You can also save the bank because the can is simpler than a petrol car and that means there is less to go wrong.




Petrol cars

For a petrol car you can get them very cheap because of the amount of them that are out there but then it the opposite you pay less for the car but then you have to pay a lot for petrol for a toyota corolla witch is a 2.0-litre it costs $25 to travel 100km so you have to decide do you want a cheaper petrol car that you will have to spend more on to run or pay more but not have to pay to much to run it.



What car is better for the environment, the e car or petrol run car?




What is bad about EV


What is bad about EV for the environment is the first major thing and pretty much the only thing is the battery. These lithium-ion batteries (LIBs) are very bad for the environment and this is because you can recycle them and you can just get rid of them easily.


What is bad about petrol cars

Petrol cars are quite bad for the environment because they are run on petroleum and this is very bad for the environment. Another bad thing about petrol cars for the environment is they have more parts than EV so making the cars is harder. And you have to use oil to keep it running.







Theses = after some consideration we have come to the conclusion that EV’s are better for the environment and for your wallet and as you can see in our PMI table EV’s got a 9 while petrol cars got a 11
