How does a RC gas engine work?
RC (radio-controlled) gas engines are a popular choice for model airplanes, boats and cars. Unlike electric motors, gas engines use a traditional internal combustion process to generate power. So, how does a gas engine work?
Firstly, it’s worth noting that RC gas engines are compression ignition, much like diesel engines. This means that the fuel doesn’t ignite at a specific time due to a spark (as in a gasoline engine), but rather ignites spontaneously when it has been crushed or compressed to a specific point. This is why glow plugs are used instead of spark plugs in gas engines, which provide the necessary heat to ignite the fuel.
The actual timing of the ignition is controlled by a combination of the compression ratio (the ratio of the volume of the combustion chamber when the piston is at the bottom of its stroke compared to when it’s at the top) and the temperature of the glow plug. Gas engines typically have a compression ratio of around 8:1 to 12:1, much higher than that of a typical gasoline engine.
Once the fuel mixture (which usually consists of gasoline and oil) has been ignited, it creates a small explosion that pushes the piston down inside the engine cylinder. As the piston moves back up, it compresses the fuel mixture, starting the process all over again. The energy created by this cycle is transferred to a rotating crankshaft, which is used to power the model airplane, boat or car.
In summary, RC gas engines work by using a compression ignition process that’s controlled by a combination of compression ratio and glow plug temperature. While they may be more complicated than electric motors, gas engines offer a unique experience and plenty of power for model enthusiasts.
