# Otto Cycle Solved Problems

Today, most general aviation or private airplanes are powered by internal combustion (IC) engines, much like the engine in your family automobile.There are two main parts to engine operation: the mechanical operation of the engine parts, and the thermodynamics through which the engine produces work and power.

For the ideal four stroke engine, the intake stroke (1-2) and exhaust stroke (6-1) are done at constant pressure and do not contribute to the generation of power by the engine.

During the compression stroke (2-3), work is done on the gas by the piston.

As aerodynamicists, we are most interested in the thermodynamics of propulsion systems and high speed flows.

On this page we consider the thermodynamics of a four-stroke internal combustion engine.

We can calculate the work by determining the area enclosed by the cycle on the p-V diagram.

But since the processes 2-3 and 4-5 are curves, this is a difficult calculation.

For an ideal Diesel cycle with the overall value of k = 1.33, rk = 15, rc = 2.1, p1 = 97.9 k Pa, find i.

Thermodynamics is a branch of physics which deals with the energy and work of a system.

If we assume that no heat enters the gas during the compression, we know the relations between the change in volume and the change in pressure and temperature from our solutions of the entropy equation for a gas.

We call the ratio of the volume at the beginning of compression to the volume at the end of compression the compression ratio, r.
