Four Stroke Cycle Engines. A four-stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle.
Intake stroke:The piston moves downward to the bottom, this increases thevolumeto allow a fuel-air mixture to enter the chamber.
Compression stroke:The intake valve is closed, and the piston moves up the chamber to the top. This compresses the fuel-air mixture. At the end of this stroke, a spark plug provides the compressed fuel with the activation energy required to begin combustion.
Power Stroke:As the fuel reaches the end of it’s combustion, the heat released from combusting hydrocarbons increases thepressurewhich causes the gas to push down on the piston and create the power output.
Exhaust stroke:As the piston reaches the bottom, the exhaust valve opens. The remaining exhaust gas is pushed out by the piston as it moves back upwards.
What are four stroke engines used for?
The four-stroke engine is the most common types of internal combustion engines and is used in various automobiles (that specifically use gasoline as fuel) like cars, trucks, and some motorbikes
Why is 4 stroke engine better?
Two-stroke engines don't live as long as four-stroke engines. The lack of a dedicated lubrication system means that the parts of a two-stroke engine wear-out faster. Two-stroke engines require a mix of oil in with the gas to lubricate the crankshaft, connecting rod and cylinder walls.
.Small and powerful .It weighs 380g,CDI and spark plug kits are not included in the startup and need to be purchased separately. CDI and spark plug sleeves are common conditions, and CDI and spark plug kits of other similar products can also be used for this product.
.If you use gasoline above No.92, the gasoline needs to be proportioned to the oil. The oil is 2T (2-stroke engine oil, the type used for ordinary motorcycles), which is adjusted from 1:25 to 1:30. A litre of petrol needs 40ml of oil
.Working Principle: Using methanol as fuel. The process of moving from one end of the cylinder to the other when the piston reciprocates within the cylinder is called a stroke .The four-stroke engine is divided into an intake stroke, a compression stroke, a power stroke and an exhaust stroke .2 laps of oil needle factory debugging, 1.5 laps of auxiliary oil needle factory debugging, and the minimum idle throttle is 2.5mm

Starts well, good power, good on fuel. Works great on my car.
Looks like a solid engine . easy installed. Other then that it started from the first pull . great engine for the price paid
I love it
IGNITION MODULE. FAILED ???
THE ENGINE WORKED FINE !!!! .BUT THE IGNITION STOPPED WORKING !! ??
I HAVE ORDERED A REPLACEMENT, BUT DELIVERY IS VERY VERY LONG !!!!
CAN YOU IMPROVE THE DELIVERY TIME ????? !!!!!!
THANK YOU !! FRANK. LAUREANNO
4 Stroke RC Engine Gasoline Engine Model Kit for RC Car Boat Airplane - Toyan FS-S100G
Very good Engine it is a work of art
Engine it is a work of art and work very well is start very fast it is the best Engine I have and I do have a lot of nitro model engine thank all of you who designed the TOYAN engines
I expected this engine to be fun but I was disappointed
This engine is well built and has a lovely finish. I expected it to be fun to change the flywheel to see what effect it has on the engine speed and also fun
to see the small "generator" light up the bulb. Unfortunately the engine did not arrive with the extra flywheel nor was an allen key included, so the flywheel could not be changed. Also the bulb did not light up. When running this engine can only produce about 2.5V, so the 5V bulb is never going to work. A nice example of an alpha type sterling engine, but I cannot rate it more than 3 stars because of the missing items
The engine received was not the one shown on the website
This engine runs fantastic, the problem is that the engine they sent does NOT match the item in the picture. I specifically wanted a thermoacoustic stirling engine with an "extended" hot tube. What they sent was the standard "short" hot tube variety. I already have 3 engines of this style, if I wanted another I could have purchased the one from this site for $23.99 or $19.99. Instead, I paid $29.99. This engine comes with bearings in the flywheel mount so it runs exceptionally fast. It is a great engine overall, but unfortunately not the engine in the sales pictures. Based of performance this engine is "5 star", however Sterlingkit should never substitute engines without customer authorization first
Well I have built this little engine was fun to build took me from 11pm to round 7 am the next morning as I was taking my time going to put it on a stand then start it up just waiting for the stand/base for it
A nicely packed kit love how the box is wood and everything is packed in black foam trays instructions are online but the contents are in plastic box’s. Like screw’s nuts and everything else needed to build it
I sent you an email describing my research and asking to speak with your engineers about reversing the rotation. I have had no response. I am a retired electrical engineer researching chirality and Tesla's concepts on Aether and gravity.
