What engine. It’s a good idea to understand how

What is a car? A car is wheeled motor vehicle that run primarily on roads. Cars came into use during the 20th century and has played a big role ever since. There are different types of cars such as electrical cars, hybrid cars, and gasoline cars. Although hybrid cars are slowly making their way to the top, gasoline cars are still the most common cars used today. Gasoline engine is an internal combustion engine with spark-ignition, designed to run on gasoline and similar volatile fuels. Just like the human body converts food to energy, a car converts gas into motion.  The gasoline that powers your vehicle doesn’t occur naturally. Gasoline is actually produced from a thick, dark substance pumped from underground which we call crude oil or petroleum. Crude oil is made up of a mixture of hydrocarbons that can be turned into a wide variety of products. The gasoline we use for automobile fuel is mainly made up of hydrocarbon chains with seven to eleven carbons. Hydrocarbons have different boiling points meaning the different chains can be separated out through a process known as distillation. Distillation is the process of purifying a liquid by boiling it and condensing its vapor. After distillation, the exact gasoline product that is desired is produced by various other processes.  Most gas stations offer three grades of gasoline: Regular, mid-grade, and premium. Generally, regular is 87 octane, mid-grade is 89 octane, and premium is 91 or 93 octane. Octane ratings indicate the gasoline’s resistance to pre-ignition. Pre-ignition is the premature combustion of the fuel–air mixture in an internal combustion engine. It’s a good idea to understand how pre-ignition works. Engines work by compressing a mixture of fuel and air and igniting it with a spark.  Gasoline was around before the invention of the internal combustion engine. For many years gasoline was considered a useless byproduct. Then in the first 2 decades of the 20th century horseless carriages in increasing droves came looking for fuel.  Researchers had found early on that the internal combustion engine ran best on light fuels like gasoline but distillation refining just didn’t produce enough of it.  The history of the automobile is a long and winding road. If you rewind the evolution of cars past GPS, past antilock brakes and automatic transmissions and even past the Model T, eventually you’ll get to the Benz Motor Car No. 1. In 1886, Carl Benz invented the three-wheeled automobile with a rear mounted engine, known as the “Motorwagen.” Benz also created his own throttle system, spark plugs, gear shifters, a water radiator, a carburetor and other fundamentals to the automobile. The first Motorwagen used the Benz 954 cc single cylinder four-stroke engine with trembler coil ignition. A trembler coil is a type of high-voltage ignition coil used in the ignition system of early automobiles. With it being the first car created it contained many new inventions. Carl Benz founded the company that would one day be called Mercedes-Benz in 1883, and they sold their first automobile in 1886.  At the beginning of the 20th century the automobile entered the transportation market as a toy for the rich. However, it became increasingly popular among the general population because it gave travelers the freedom to travel when they wanted to and where they wanted. As a result, in North America and Europe the automobile became cheaper and more accessible to the middle class. With the popularity of automobiles, it made a big impact to the economy during the Great Depression when unemployment rates were high. It also changed city life drastically by accelerating the outward expansion into the suburbs which helped businesses and industries. With other automobile-related phenomena, the trend is most noticeable in the United States but is rapidly appearing elsewhere in the world. What is a gasoline engine? A gasoline engine is any class of internal-combustion engines that generate power by burning gasoline or a gasoline mixture such as ethanol. Gasoline engines can be grouped into a number of types. The two basic engine types are piston-and-cylinder engines and rotary engines. In a piston-and-cylinder engine the pressure produced by combustion of gasoline creates a force on the head of a piston that moves the length of the cylinder in a reciprocating, or back-and-forth, motion. This force drives the piston away from the head of the cylinder and performs work. The rotary engine does not have conventional cylinders fitted with reciprocating pistons. Instead, the gas pressure acts on the surfaces of a rotor, causing the rotor to turn and thus perform work. One of the most important components to a gasoline vehicle is a fuel system. The function of the fuel system is to store and supply fuel to the engine. Although fuel systems vary from engine to engine, all systems are the same in that they must supply fuel to the combustion chamber and control the amount of fuel supplied in relation to the amount of air. Fuel is stored in the fuel tank and the fuel pump draws fuel from the tank, then travels through the fuel lines and is delivered it through a fuel filter to the fuel injectors. As the fuel is delivered, the final conditions for providing complete combustion are atomization and the spray pattern of the fuel. The main part of a car engine are the cylinders. Cylinders are the central working part of a reciprocating engine or pump, the space in which a piston travels. They’re made of super-strong metal and sealed shut, but at one end they open and close like bicycle pumps. At the top of each cylinder, there are two valves. These two valves are called inlet valve, and outlet valve, but they both have different jobs. The inlet valve allows fuel and air to enter the cylinder while the outlet valve lets the exhaust gases escape. On the top of the cylinder there is also a sparking plug, which is an electrically controlled device that makes a spark to set fire to the fuel. At the bottom of the cylinder, the piston is attached to a constantly turning axle called a crankshaft. The crankshaft powers the car’s gearbox which, in turn, drives the wheels. Although electric and hybrid vehicles are new right now, gas-powered vehicles seem to be the king of the road. Advocates of the environment have called for the lessened use of gas to power cars given that they are detrimental to the world we live in. Despite there are still advantages to a gas-powered car. The price of technology needed to power hybrid cars will continue to drop, but gasoline-powered vehicles are still cheaper than these newer kinds of cars. Hybrid cars takes a lot of research and development which means shelling out a lot of money as well. The technology behind gas-powered cars has been around for many and has seen improvements over the course of time as well.  Hybrid cars may also cost more to maintain given the kind of components used to build them. For instance, when an electric motor or battery pack needs to be replaced, one would most likely need to go to a specialist while breakdowns with gas-powered vehicles can be fixed by someone with a good knowledge of cars. With most gasoline cars, they cover wider distances than hybrid cars. Averagely a 20-gallon gas tank on a car has about an average fuel economy of 20 miles per gallon. This means that a gas-powered vehicle can travel about 400 miles before it needs to be refueled. This is different for hybrid cars because it depends on how much energy is consumed during travel. With hybrid cars there aren’t many charging stations like gas stations when you can find at various exits around the country. Although gasoline vehicles have benefits, it also has a few cons. Gasoline cars contribute to pollution and given the concern over global warming, most manufacturer are looking into redefining their cars on how they operate to make them more eco-friendly. Not only do cars cause a problem in our environment, they cause health problems to humans. Nearly one half of all Americans—an estimated 150 million—live in areas that don’t meet federal air quality standards. Passenger vehicles and heavy-duty trucks are the main sources of this pollution. According to the Department of Public Health, high levels of chemicals taken in from gasoline exposure like benzene may cause cancer. The inhalation of fumes can lead to confusion, dizziness, headaches and breathing difficulties. Gasoline cars rely on fossil fuel. The United States uses 28% of its total energy each year to move people and goods from one place to another. Since we can only get estimates of fossil fuel, there is no exact proof of how much more is there to use. As such, people are calling for alternative methods to be used now rather than later. There have been different alternatives made such as hybrid and electric cars running on roads. Another problem with that is hybrid and electric cars are more expensive than gasoline cars and not everyone can afford to own these hybrid and electric cars to help keep the environment healthy. It’s strange to think that things that we put in our cars can cause an oil implication. The Middle East holds an extreme degree of authority in the world due to the world’s dependency on the oil deposits found in that region. Finding an alternative resource can limit other countries power and bring more peace. Doing that will limit these foreign leaders and nations would not have such a stranglehold on the rest of the world due to oil. The engineering of cars has changed drastically from how we drive them, how we power them and even how we own them. Plug-in vehicles of any kind are just a silver of auto sales today. Eventually electric cars will take over the market. Companies like Tesla, Volkswagen and others are building electric car charging networks along America’s highways. These charging stations will help the last big concern most people have with electric cars, the ability to easily travel a distance greater than that of a single charge. Advances in computers, sensors and software are making real self-driving cars possible. Many luxury models can already pretty much drive themselves on highways and in stop-and-go traffic with minimal human intervention.  The future for electric vehicles is bright. Plummeting battery prices, longer-range models, and more charging stations are driving forward electric vehicle sales. With the auto industry investing billions to meet strong pollution standards globally. Electric vehicles benefit us and our environment in many ways. Electric vehicles will reduce harmful exhaust emissions is good news for our health. Better air quality will lead to less health problems and costs caused by air pollution. Recent findings have shown that several electric vehicles features can improve safety. Electric vehicles tend to have a lower center of gravity that makes them less likely to roll over. They can also have a lower risk for major fires or explosions and the body construction and durability of electric vehicles may make them safer in a collision.  Another alternative power vehicles are plug-in hybrid cars. The plug-in hybrid, gets some or most of its juice from electrical energy stored in the car’s batteries. Plug-in hybrid still uses a gasoline-powered engine, but the gas kicks in when the battery runs down. Some of the battery packs can be charged in standard electric outlets at home or work or in an electrical generator found in the vehicles. An electric car or electric vehicle gets its power from an electric motor instead of an internal combustion engine. Servicing a hybrid is one of the few downsides of owning this car. Not all service facilities have the equipment and expertise needed to service a hybrid, and so you will most likely need to have the car serviced by the dealer or manufacturer.  Just like the human body converts food to energy, a car converts gas into motion. The gasoline that powers your vehicle doesn’t occur naturally like water in a stream.  The gasoline we use for automobile fuel is mainly made up of hydrocarbon chains with seven to eleven carbons.  Octane ratings indicate the gasoline’s resistance to pre-ignition. Engines work by compressing a mixture of fuel and air and igniting it with a spark. Gasoline was around before the invention of the internal combustion engine.

As long as everyone knows the need to make our world a better place by reducing emissions and the amount of fuel cost caused by gasoline powered cars our world can be better.
