Early Automobiles Vehicles have changed over time like many other things, but the engine that powers these vehicles has gone through the most changes. The internal combustion engine has become a huge part in everyday life. These engines have allowed people to travel across the country, generate electricity, and fly around the world. This engine has been a perpetual source of exploration ever since Henry Ford mass produced the first Model-T. Automobiles have evolved over time along with many other things; there are many fundamentals to learn about how the engine works, different types of engines, and the history of the gas engine. The first thing to learn is how the basic engine works. According to Nancy Hall, writing for the National …show more content…

7). The combustion increases the temperature of the exhaust gases, any residual air in the combustion chamber, and the combustion chamber itself. From the ideal gas law, the increased temperature of the gases also produces an increased pressure in the combustion chamber; the high pressure of the gases acting on the face of the piston cause the piston to move to which initiates the power stroke (para. 8). Unlike the compression stroke, the hot gas does work on the piston during the power stroke. The force on the piston is transmitted by the piston rod to the crankshaft, where the linear motion of the piston is converted to angular motion of the crankshaft. Hall’s article for NASA states that the work done on the piston is then used to turn the shaft (para. 8). Having produced the igniting spark, the electrical contact remains opened. During the power stroke, the volume occupied by the gases is increased because of the piston motion and no heat is transferred to the fuel/air mixture (para. 9). As the volume is increased because of the piston 's motion, the pressure and temperature of the gas are decreased. Heat that is left over from the power stroke is now transferred to the water in the water jacket until the pressure approaches atmospheric pressure; the
