railroad cars Technical - Essay ExampleAfter World War I, the United States became a refilling of economic growth, from new inventions to growth of an expanding road infrastructure.This economic growth helped accelerate the need for the automobile. The automobile diligence grew quickly because of many innovative inventions. In the 1950s innovation was getting greater speed through the frame of more powerful engines. In the 1960s innovation was building a sleek but performance impelled auto. In the 1970s, the automobile and gas shortage led many automakers to look for innovative ways to function emission and decrease gas consumption. The convergence of computer and auto industries helped improve gas mileage and clip protrude on emission. The last 25 years of the car industry has seen technical and design advances that increase standardization, platform sharing, and CAD design. Body styles find changed to include the hatchback, minivan and sport utility vehicle (Consumer Guid e p 10).Automotive engines are called internal combustion (IC) engine because the fuel that runs them is burned internally, or inside the engines. on that point are two types, reciprocating and rotary. Reciprocating means moving up and down, or back and forth. Almost all automotive engines are of the reciprocating type. In these engines, pistons moves up and down, or reciprocate, in cylinders. This type of engine is called piston engine. Rotary engines have rotors that spin, or rotate. The only such engine now used in automobiles is the Wankel engine. 1 )Types of Engine brass1.1 Car EngineThe main function of a cars engine is to make it move. Engines come in a range of strengths as well as speeds. All recent engines are made of vital parts. Car engines are built around cylinders (generally something from 2-12 of them, however usually 4, 6 or 8) in which the fuel is burnt. Super-strong metal and sealed shut, arte used to make these cylinders however at one end open and closes exa ctly equivalent bicycle pumps these consist of tight-fitting pistons (plungers) that may slide up as well as down in them. At the swipe of every cylinder, there are two valves. The inlet valve permits fuel as well as air to go into the cylinder the outlet valve lets the exhaust gases loose. At the very top of the cylinder, a sparking plug (or spark plug) is present, this is a device which is controlled electrically as well as makes a spark to put fire to the fuel. At the base of the cylinder, the piston is connected to a continually spell axle that is known as a crankshaft. The crankshafts function is to powers up the gearbox of the car which then drives the wheels. The capacity of an engine function is depends on the power or the horse power that it develops. This in turn is reliant on the ability of the engine. 2.)Diesel Engines In 1892, Rudolph Diesel, a German engineer developed the diesel engine engine. Unlike the gasoline engine, the diesel engine is capable of spontaneou s combustion of liquid fuel without requiring spark ignition. The key advantage of the diesel engine over the gasoline engine is its fuel economy as well as posture (en.wikipedia.org/wiki/Diesel_engine). Known as a workhorse the diesel engine became the engine of choice for heavy construction machinery, excavation
