Amit Kumar submitted a report on internal combustion engines. The report introduces IC engines and their parts. It explains how IC engines work through starting and operation. It describes the different types of IC engines based on number of strokes, ignition type, mechanical/thermodynamic cycle, and configuration. Diagrams of two-stroke and four-stroke engines are included. The conclusion discusses where high power-to-weight ratio engines like turbines are used, as well as common uses of reciprocating piston engines in land, sea, and air vehicles. It also summarizes the Otto and diesel cycles that govern gasoline and diesel engines respectively.

CONCLUSION
After this section I conclude that
 Where very high power-to-weight ratios are required, internal combustion engines appear in the form
of combustion turbines. Powered aircraft typically uses an ICE which may be a reciprocating engine.
Airplanes can instead use jet engines and helicopters can instead employ turboshafts; both of which are
types of turbines. In addition to providing propulsion, airliners employ a separate ICE as an auxiliary power
unit.
 Reciprocating piston engines are by far the most common power source for land and water vehicles,
including automobiles, motorcycles, ships and to a lesser extent, locomotives (some are electrical but most
use Diesel engines. Wankel engines are used in some automobiles and motorcycles.
 Most truck and automotive diesel engines use a cycle reminiscent of a four-stroke cycle, but with a
compression heating ignition system, rather than needing a separate ignition system. This variation is called
the diesel cycle. In the diesel cycle, diesel fuel is injected directly into the cylinder so that combustion
occurs at constant pressure, as the piston moves.
 Otto cycle is the typical cycle for most of the cars internal combustion engines that work using gasoline as a
fuel. Otto cycle is exactly the same one that was described for the four-stroke engine. It consists of the same
four major steps: Intake, compression, ignition and exhaust.
 PV diagram for Otto cycle On the PV-diagram, 1–2: Intake: suction stroke 2–3: Isentropic Compression
stroke 3–4: Heat addition stroke 4–5: Exhaust stroke (Isentropic expansion) 5–2: Heat rejection the distance
between points 1–2 is the stroke of the engine. By dividing V2/V1, we get: r, where r is called the
compression ratio of the engine
