engine combustion network

jet engine

In a 4-stroke internal combustion engine for example you have intake compression power and exhaust happening separately and you need spark plugs (or glow plugs) to ignite the fuel each cycle In a jet engine however instead of 4 independent cycles you have a constant flow of air through the engine

Why is the combustion temperature in a turbojet engine

Because the fuel-air mixture in a turbine is much leaner than what it would be for a stoichiometric combustion It needs to stay lean to restrict the maximum gas temperature inside the engine - higher temperatures lead to exponentially shorter lives of the turbine components

Internal combustion engine

An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit In an internal combustion engine the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine

Air Fuel Ratio in Internal Combustion Engine

Dec 28 2016Higher compression ratio and larger piston bore in an engine produce higher power and torque The higher compression in a combustion chamber makes the air and fuel particles compressed in larger density and in high pressure Larger piston geometry (bore) will let more air passing through the combustion chamber Both of these variables will create []
