There are several types of FS engines with unique features. They include:
Two-stroke engines
Two-stroke FS engines are popular in the RC world due to their high power-to-weight ratio. Unlike four-stroke engines, they complete a power cycle in two strokes of the piston, which results in a power impulse with each stroke. These engines also have a simpler design with fewer moving parts, which makes them lighter and more affordable. However, these FS engines tend to be less fuel efficient, and their emissions levels are higher than those of the four-stroke FS engines.
Four-stroke engines
Four-stroke FS engines have become a popular choice among RC enthusiasts, particularly in the model aircraft community. Although these engines are typically heavier and more complex than the two-stroke ones, they are known for their fuel efficiency and lower emissions. Also, four-stroke FS engines generate a lot of torque, making them suitable for larger and heavier RC models. Furthermore, the four-stroke FS engines are more reliable and require less maintenance than the two-stroke ones.
Electric engines
Electric FS engines use rechargeable batteries to power an electric motor. These FS engines are generally quieter and cleaner, producing no emissions. Electric engines also offer a consistent power delivery and require less maintenance. However, they have a limited run time and a shorter range compared to the combustion engines.
Gasoline engines
Gasoline engines are typically more fuel efficient than methanol-based engines. They generate a lot of torque, making them suitable for various RC applications. Also, gasoline engines tend to have a longer lifespan because they operate at lower RPMs compared to the other combustion-based engines.
Diesel engines
Diesel engines are known for their high torque and fuel efficiency. They offer longer run times and are more reliable compared to other engines. However, diesel engines tend to be heavier and require more maintenance than other FS engines.
The following are general specifications one can expect from FS engines:
Cylinder Arrangement
The engine has a vertical or horizontal row of cylinders that contains about one to six cylinders.
Ignition System
FS engines possess a capacitive discharge ignition (CDI) system or a inductive ignition system that support engine performance.
Cooling System
FS engines have a cooling system that controls the temperature of the engine. The control can be done with the help of air or water.
Fuel System
FS engines contain a fuel system that contains a fuel tank, fuel lines, and a fuel delivery system which is responsible for delivering fuel to the engine.
Lubrication System
The FS engine contains a lubrication system that reduces the friction between moving components within the engine. This is done by supplying oil to these components.
Crankshaft
The crankshaft in the FS engine converts the linear motion of the pistons into rotational motion so as to power the propeller or rotor.
Valvetrain
FS engines have a Valvetrain that controls the opening and closing of valves in synchronization with the movement of the pistons. The Valvetrain consists of valves, springs, and actuators.
Combustion Chamber
The combustion chamber is a chamber where fuel and air are ignited to produce power. The combustion chamber is designed to increase or decrease the compression ratio of the engine.
Engine Timing
The timing of the FS engine is controlled mechanically or electrically with the help of a timing system. This timing system ensures that the ignition and valve operation occur at the right time with respect to the piston movement.
Starting System
FS engines have starting systems with electric starters or manual starters, which are used to initiate the engine.
Exhaust System
The exhaust system in an FS engine controls the emission of exhaust from the engine to the atmosphere. The exhaust system also reduces noise produced by the engine while operating.
Performance Specifications
FS engines have performance specifications that include power output, torque, and engine speed, which vary depending on the engine model and size.
