COMBUSTION ENGINES 6.1 Introduction Perhaps the best-known engine in the world is the reciprocating internal combustion (IC) engine. Virtually every person who has driven an automobile or pushed a power lawnmower has used one. By far the most widely used IC engine is the spark-ignition gasoline engine‚ which takes us to school and work and on pleasure jaunts. Although others had made significant contributions‚ Niklaus Otto is generally credited with the invention of the engine and with the

Valuation of equity Example based on dividend discount model : Vardhman limited’s earnings and dividends have been growing at a rate of 18% per annum. This growth rate is expected to continue for 4 years. After that the growth rate will fall to 12 % for the next 4 years. Thereafter‚ the growth rate is expected to be 6 % forever. If the last dividend per share was RS. 2.00 And the investor’s required rate of return on verdhman’s equity is 15% what is the intrinsic value per share? Step 1: the

The Diesel Engine Diesel engines are very similar to the gasoline engine you may find in a car. They both are internal combustion engines‚ have a four stroke cycle‚ and convert chemical energy from fuel into mechanical energy. However‚ the manner in which the combustion stroke is attained sets these two engines apart‚ and although a seemingly meaningless change‚ a large change in efficiency results. (Diesel Engines vs. Gasoline Engines) The diesel engine was invented by Rudolf Diesel in 1892

WANKEL ENGINE The Wankel engine‚ invented by German engineer Felix Wankel‚ is a type of internal combustion engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons. Its four-stroke cycle takes place in a space between the inside of an oval-like epitrochoid-shaped housing and a rotor that is similar in shape to a Reuleaux triangle but with sides that are somewhat flatter. This design delivers smooth high-rpm power from a compact size. Since

Diesel Engines Diesel engines are everywhere; they are used in all sorts of vehicle platforms. From Volkswagen Jetta’s‚ to big eighteen wheel tractor trailer trucks. They provide more torque then a regular gasoline engine because of the long stroke of the piston. Most diesel engines make peak torque at very low rpm. Diesel engines do not have spark plugs. They develop combustion by heating up the air going into the cylinder‚ while the air is heated the fuel injector sprays into the bowl of
