Synopsis:

To provide information concerning fundamentals of internal combustion engines (ICE): principles of combustion, formation of pollutants, gas exchange, super- and turbocharging; description of tools for fuel injection, mixture formation, valve gears, combustion realization, exhaust aftertreatment, lubrication and cooling.

Requirements:

Syllabus of lectures:

1.Principles of ICE performance; laws of thermodynamics; conservation laws for open system; basic distribution of ICE. Operation and control of system engine/load. Main engine characteristics.

2.ICE cycles - HP (high pressure) phase (closed system) in real and idealized form. Idealized cycles, example of analytical efficiency calculation. T-s diagram, efficiency assessment. Carnot cycle, real limits of ICE cycles (T, p, v). Stirling cycle.

3.LP (low pressure) phase (charge exchange) - real and idealized form at 4 stroke engine. 2 stroke engines. Volumetric efficiency and cylinder charging. Indicated efficiency and pumping work. Mechanical efficiency.

4.Schemes of gas turbines and super-turbocharged engines. Gas turbine cycle (Ericsson-Brayton), heat regeneration. Adiabatic irreversible changes. Principle of turbine performance - momentum change at blades.

5.Fuels - chemical components of HC fuels. Raw oil processing. Stoichiometry of fuel/air mixtures. Burnt gas composition.

6.Thermochemistry of fuels - Hess and Kirchhoff equations, calorific value. Reaction mechanisms. Laws of chemical kinetics / Guldberg-Waage&Arrhenius. Reaction equilibrium. Dissociation of combustion products.

7.Adiabatic flame temperature. Chemical efficiency. Elementary processes in mixture preparation, combustion and heat transfer - air/fuel mixing, pre-flame reactions, ignition delay, premixed flame - deflagration or detonation, diffusion flame.
