Different Types of R/C Engines

R/C engines models are powered in a variety of ways. From the sight of radio control engines, there are on-road, off-road, aircraft, marine, and monster truck engines. In this post, we will list some of popular engines.

Usually, electric models use small motors, powered by battery cells. However, engines typically can only run on one type of fuel and require adaptations to adjust the air/fuel ratio or mix to use other fuels.

Gasoline/Petrol Engine
It is the most common internal combustion engine type. Gasoline is a liquid mixture created form crude oil. In a gasoline engine, a mixture of gasoline and air is sprayed into a cylinder, then the spark plug and some type of ignition system to ignite the gas-air mixture to produce power. Gasoline engines can be built to meet the requirements of practically any conceivable power-plant application, include motor cars, motorcycles, motorboats, aircraft and other small engines needs. But they are usually reserved for much larger planes than a beginner will be flying.

Gasoline engines are being developed to deliver more torque at the low end, it runs at higher speeds than diesels.

Gas Engine
In the US, due to the widespread use of "gas" as an abbreviation for gasoline, sometimes call gas engine a gasoline engine. But the true is, gas engine runs on a gas fuel (coal gas, producer gas, biogas or natural gas) and gasoline engine is working petrol (gasoline) and similar volatile fuels. Gas engine has long been a clean, economical, and readily available fuel.

Diesel Engine
Diesel engine or compression-ignition engine uses the heat of compression to initiate ignition to burn the fuel that has been injected into the combustion chamber. Thus, they require much more strongly in building and more expensive than gasoline engines. Diesel engine is known for its outstanding pulling power, longevity and fuel economy, hence its popularity in trucks, buses and boats.

Nitro Engine
Generally, nitro engines are very small, they offer use in small to medium size RC vehicles, and running on nitro fuel. The biggest difference between nitro engines and aircraft engines is the ability to sustain RPM. Nitro engines tend to break if run at full throttle for a full tank of fuel. Nitromethane is highly combustible substance that is generally only used in very specifically designed engines. The biggest problem is they have relatively short life-span.

Glow Engine
Glow engine is a common term in the hobby and sport of RC vehicles. A "glow engine" is what as a kid we used to call "gas engines", but the truth of the matter is, they do not burn gasoline. RC glow engines use nitro fuel, a methanol-based fuel with nitromethane and oil added. Most nitro R/C models use a 2- or 4-stroke glow engine, sized specifically for that model. Advantages include economy, easy starts and good power.
