In our life, cars occupy much space. We use them many times to transport, to visit etc. The most important part for cars is engine. Engine is the main part of cars. There are many types of engine. It is generally used internal combustion engine for cars. This type engine works with gasoline, diesel and gas. People wonder that how they work, because when people look the engine, they think that it is complicated. It isn’t complicated. Some gasoline comes to piston space and is burned. The burning generates energy and gives a motion to pistons. This motion is circular motion and pistons convert it to linear motion.
It is short form of how engine works. For engineers, we need to know parts and systems of engine. Sparks, pistons, valves, spark system, burning time etc. are some parts and systems. Pistons convert circular motion to linear motion. Sparks helps to burn liquid fuel in the cylinders. Valves send liquid fuel to cylinders and after burning they send CO2 AND CO to outside. Next paragraphs they will be explained again and what is done on them will explained.
The working of engine is explained. The other important part for engine is their efficiency. Efficiency means ratio of power taken and power given. The efficiency of internal combustion engine is about 14 % - 26 % (U.S. Department of Energy). People can think that what happens to rest of power. 70 % - 72 % engine loses power (thermal, friction, pumping and combustion). 5 % - 6 % drive train loses. 5 % - 6 % parasitic loses. As can be seen, the efficiency of internal combustion engine is low, because of that most time people try to increase it. To increase efficiency of internal combustion engine has been an aim for people.
There are the some systems are used to increase e...

...im for people, because when engine has more efficiency, it spends low liquid fuel. It means saving resources. Also it helps to economy. In emerging technology, researches and experiments have been in progress. It looks it will continue forever.

If we increase the efficiency remarkably, we may be able to consume fewer fossil fuels and may be able to reduce carbon emissions into the atmosphere therefore saving Mother Earth. This will not happen shortly, but in the future when my great-great-grandchildren are in the working force designing these engines.
Driven in large part by global initiatives and the potential for stringent regulations, the past decade or two has seen a marked increase in the importance of improvements with respect to environmental standards, including emissions and increases in fuel economy. In 2002, Cummins Emissions Solutions was launched after the need was identified for an emission solution that would help engines meet future regulations. In 2006, Cummins pioneered a hybrid diesel-electric bus which reduced fuel consumption and greenhouse gasses by more than 30 percent and me...
Insert the key, turn, and vroom. And down the road you go. Most people take for granted the strange conglomeration of metal and plastic under that sheet of metal either in front or back of their vehicle. The engine as you may have guessed, is modern marvel- so to speak. They’re found in cars, trucks, boats, airplanes…All with various power outputs.

In Internal Combustion Engine Crankshaft play an important role to convert the reciprocating motion of piston in to rotational motion with the help of four link mechanism. Crankshaft is must be strong enough to take the downward force of the power stroked without excessive bending so mostly the life and reliability of engine is depend on the strength of crankshaft. In Internal Combustion engines, the transient load of maximum cylinder gas pressure is transmitted to crankshaft through the connecting rod, However Crankshaft convert reciprocating motion of the piston along with connecting rod to the
In an internal combustion engine, the fuel inside it is burned in the air at the top of its pistons. Most internal combustion engines are mainly used in small vehicles. In the 19th century external combustion engines were commonly used to power large steamships and trains. The combustion chamber of an internal combustion engine is limited in part. When the fuel is burnt in the combustion chamber, hot gasses can straight away push the piston down. Due to the pressure of the gas being high it quickly increases to follow the piston and to continue pushing on it. As the gas pressure goes low, the gas has then pushed the piston to its bottom place. The heat in an internal combustion chamber is made inside the engine, because it can quickly perform on the engine pistons. This then lets the internal combustion engine to be smaller and lighter than the external combustion. Due to this internal combustion engines are commonly used for mobile applications with low power. In an Internal combustion engine the increase of high temperature and pressure gases made by combustion applies straight force of the engine. Like the pistons, turbine blades or a nozzle. This force changes the component over a distance, which makes mechanical energy. ‘Internal combustion’ refers to an engine which the combustion is alternating.
We've all seen them before, the mysterious chunks of metal under the hoods of our cars. They start when we turn the key and take us where we want to go. But how does an engine work? Internal combustion engines are a very important part of everyday life. We use them in our cars, trucks, airplanes. boats, snowmachines, 4 wheelers, and heavy machinery. These pages will help familiarize you with the basic concepts of how an engine works, an understanding of engine output, and some information on how forced induction or "boost" increases power output.
In this report I will explain the fuel systems in an automobile. I will cover different parts and how they work. First thing to do is explain how the fuel system works. The purpose of the fuel system is to store and supply fuel to the cylinder chamber where it can be mixed with air then vaporized and burned to produce energy. The fuel, which can be either gas or diesel is stored in a fuel tank. A fuel pump draws the fuel from the gas tank through lines and brings it through a fuel filter. Next it goes to either a carburetor or fuel injector and then delivered to the cylinder chamber for combustion.
Diesel Engine - The Diesel Engine is an application of 2nd law of thermodynamics. It is similar to the Otto cycle, the fuel used is different which makes working of the engine different, thought output is rotational motion .the compression ratio is much high as compared to any other as no spark plug is used only adiabatic compression ration leads to burning of fuel [4].

Take a V-8 engine, for example. A V-8 engine has eight cylinders. Whenever the engine is running, the eight of these cylinders are working, burning fuel and air. Most cars, trucks and SUVs with V-8 engines have them because the cylinders of an engine usually has, the more powerful it is. That 's why V-8 engines in sports cars or heavy trucks are usually observed. But while people like V-8 engines, as they are fast and can pull heavy loads, most people are not doing things all the time.
Most cars use what is known to be called a four stroke combustion cycle which turns gasoline into movement. There are four strokes that are inside the engine. Which are the intake stroke, compression stroke, combustion stroke, exhaust stroke. The piston and the crankshaft work together by the connecting rod also the rod bearings which is the main components for the engine. The intake stroke is when the intake valves open while the piston is at the highest point while the piston moves down it takes in gasoline and air. Compression stroke is when the piston is moving up again to squeeze the fuel and air mixture , then the compression explodes making it more powerful. The combustion stroke is after the piston is done going from bottom to top of the stroke it ignites itself by the spark plug which sparks it and then inside the cylinder the gas is charged to make an explosi...
It runs by explosions of a fuel and air mixture that are ignited by a spark. Valves open and close allowing a fuel-air mixture to enter the combustion chamber.The spark ignites the fuel air mixture making a explosion that explosion moves the piston downwards .The explosion makes exhaust which needs to be taken out. The other valve opens and lets out the exhaust . That goes on in a cycle over and over making the pistons move making the back wheel
A steam engine is an external combustion that converts heat energy, in the form of steam, into mechanical energy. Steam is generated through combustion of a fuel, i.e. Coal, heating a boiler filled with water, which evaporates to produce steam that expands do drive a piston connected to a flywheel in a rotary motion. The flywheel then transmits energy created to a crankshaft which is used to provide power to machines, such as locomotives, fluid pumps, and machine tools. Waste steam is then expelled from the engine through an exhaust, or can be condensed and repurposed in some steam engine designs (Croft and Tangerman, 1939).
