Internal Combustion Engine- An internal combustion engine (ICE or IC engine) is a heat engine in which fuel is burned in a combustion chamber that is part of the working fluid flow circuit with an oxidizer (typically air). The following are examples of different types of heat engines found in thermodynamics: Despite the fact that all of the ideas come from Thermodynamics, each type of heat engine converts heat energy into mechanical work using a different principle. Heat engines have been classified according to the concept that governs their operation. Friction and drag also render some energy ineffective. Some heat is generally lost to the environment during this process and is not converted to work. Any system with a non-zero heat capacity can be used as the working substance, however, it is most commonly a gas or liquid. Using the qualities of the working substance, some of the thermal energy is turned into work throughout this process. The working material produces work in the engine's working body while transferring heat to a colder sink until it reaches a low-temperature state. A heat source produces thermal energy, which raises the temperature of the working substance. It accomplishes this by lowering the temperature of a working substance from a higher state temperature. A heat engine is a device that turns heat into mechanical energy that can then be utilized to do work.
