1. Fuel
ICEs burn a variety of fuels, including gasoline, diesel, natural gas, and propane. Steam engines typically burn coal, wood, or oil.
2. Combustion process
In an ICE, the fuel is mixed with air and burned inside the engine's cylinders. The combustion process creates hot, high-pressure gases that expand and drive the pistons. In a steam engine, the fuel is burned in a separate boiler to produce steam. The steam is then directed into the engine's cylinders, where it expands and drives the pistons.
3. Efficiency
ICEs are more efficient than steam engines. This is because the combustion process in an ICE occurs at a higher temperature, which allows for more complete combustion of the fuel. Steam engines also lose a significant amount of energy through the exhaust steam.
4. Power
ICEs are more powerful than steam engines. This is because they can operate at higher speeds and produce more torque. Steam engines are typically used for low-speed, high-torque applications, such as powering ships and locomotives.
5. Size and weight
ICEs are smaller and lighter than steam engines. This is because they do not require a separate boiler and they can operate at higher speeds. Steam engines are typically larger and heavier, which makes them less suitable for use in vehicles.
6. Emissions
ICEs produce more emissions than steam engines. This is because the combustion process in an ICE produces harmful pollutants, such as carbon monoxide, nitrogen oxides, and hydrocarbons. Steam engines produce water vapor and carbon dioxide, which are less harmful to the environment.
7. Applications
ICEs are used in a wide variety of applications, including cars, trucks, motorcycles, boats, and generators. Steam engines are typically used for powering ships, locomotives, and stationary machinery.
In summary, ICEs and steam engines are both types of heat engines that convert the energy of burning fuel into mechanical energy. However, there are several key differences between the two types of engines, including the fuel they use, the combustion process, efficiency, power, size and weight, emissions, and applications.
