Toyan FS-S100G 4 Stroke RC Engine Four Stroke  Gasoline Engine Kit for RC Car Boat Plane

A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction.
The principle used in a four stroke petrol engine is commonly known as Otto Cycle. It states that there would be one power stroke for every four strokes. Such engines use a spark plug which is used for the ignition of the combustible fuel used in the engine. Most of the cars, bikes and trucks use a 4 stroke engines.

Features:

1, Powerful Performance: While it starts, the rotate speed can up to 13500 RPM / Mins.
2, Fuel: The fuel for this Four-stroke Engine is Petrol, When you use gasoline above No.92, it needs to be proportioned to the oil. The oil is 2T (2-stroke engine oil, the type used for ordinary motorcycles).  The Mixture Ratio is 1:25 or 1:30 (2T : Gaoline).  A liter gasoline needs to mix with 40ml of oil.
3, Extra Accessories Needed for Operation: Spark plug + Start ESC Connector + Oil Tank + 30cm Oil Tube+ CDI Kit. (click  buy directly)
4, Priority Gift Option for Many Applications : The four-stroke engine can used on 1:10, 1:12, 1:14 scale car model or ship model and other equipment. Also, it can be used for classroom display as teaching Aids. Besides, it is ideal Gift for engine lovers.

Operation Methods:

1, CDI Connection Method:
One is power wire, Black wire should connected to the sensor at the bottom side of engine. The middle wire can connected to tachometer， which can show RPM. ( You can choose to connect or not, it won't affect the engine performance )
2, CDI can only be used with 7.4V battery
3, Connect three wire randomly. start the engine, if the engine is idling, exchange any two starter motor wire arbitrarily. (Don't worry, it won't cause any hurt to you)
4, For 11.1V battery is for starting motor. Connect the starter connection cable to 11.1V battery.
5, Then press start button.

Tips:

1, Do not touch the motor fan with your hands to avoid scratching.
2, Do not touch the cylinder department with your hands to prevent burns.

Working of a Four Stroke Gasoline Engine

A stroke is the movement of the piston from the top, to the bottom of the cylinder. the Four Stroke Petrol Engine uses a cycle of four strokes and petrol as the fuel. Each cycle includes 2 rotations of the crankshaft and four strokes, namely:
1.An Intake Stroke
2.A Compression Stroke
3.A Combustion Stroke also called Power Stroke
4.An Exhaust Stroke

Why Choose Toyan Four Stroke Engine instead of 2 Stroke Engine?

1, 4 stroke engine has higher torque at lower rpm as compared to 2 stroke engine.
2, More fuel efficient than 2 stroke engine.
3, It creates less pollution as no oil is burned during combustion.
4, 4 stroke engine lasts longer than 2 stroke engine as 2 stroke engines are designed for high rpm and at high rpm engines wears at faster rate hence less durable.
5, It has a separate oil chamber.
