About Four-stroke engine

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.

  1. Intake stroke: The piston moves downward to the bottom, this increases the volume to allow a fuel-air mixture to enter the chamber.
  2. 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.
  3. Power Stroke: As the fuel reaches the end of it’s combustion, the heat released from combusting hydrocarbons increases the pressure which causes the gas to push down on the piston and create the power output.
  4. 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.



Features:

.Small size and large horsepower: Weighing 1150g, need 7.4V or 11.1V battery start, the battery needs to be T-plug, the female head is on the engine end, and the electric rotor is needed.

.Fuel:The electric rotor is a general-purpose product, using methanol fuel, this kind of fuel formula is generally: 20% castor oil, nitromethane 5-30%, the rest is methanol; this product does not require high concentration methanol fuel, and can be used at a concentration of 20-25%.

.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

.For Age: 14 years old or older; adapt to 1:10, 1:12, 1, 1:14 remote control car, remote control ship, remote control aircraft, etc., can also be converted into an educational kit for display and education

.Note:

runs big
Size: 7.5, Color: Camel
I am always a size 8 in boots, sandals, sneakers and read these ran large so ordered a size 7.5. They are still too big on me. I sent back for a 7 and I will update when I get those. They are very, very cute and comfortable! I love the cloth that goes over the foot!! That makes them seem a bit more fancy than regular flip flops. They also do sound like regular flip flops, so if you want a quiet sandal these are not for you. They are very cushioned and I can def feel the arch support. You will need to size down at least half size and maybe one whole size. The hardest thing for me was to pick a color! May have to get several pair! Just ordered my mom the dark blue and I know she will love them!!! Highly recommend, especially for the low price! Update: Got the 7 and are still too big. As I said, I got my mom the 6 so I tried them on and they are still a tad too big on me!!! BTW the sizes 8,7.5,7 and the 6 I can hardly see any difference whatsoever! They don't come in 5 1/2 so I am sending the 7 back for a 6 and keeping those just because they are so darn cute and comfortable! I also don't have a very thick foot so I wish the straps were a tad tighter, but I will deal with it. So, to sum up: Be sure to size down at least one size and maybe even two. Returns are easy, so maybe try a few different sizes! I haven't worn a size 6 since I was in about the 6th grade, so not sure what is going on with the sizing. Oh yeah, I did get three different colors and the sizing was the same with all three. HTH! Good luck!

Super comfortable from the first wear! Unique soles
Size: 10, Color: White Khaki
My husband actually picked these shoes out and bought them for me without my knowledge for a vacation we were going on. When I discovered he had bought me some sandals I assumed they would likely be super uncomfortable, too narrow, weird looking etc lol. I definitely didn’t give him enough credit. I absolutely love these shoes! They are incredibly comfortable! They match pretty much everything. The bow at the toes is so cute! The soles are a very cool sturdy and hard almost wood like material, while also feeling like a dream to wear. I ended up wearing them with my bathing suits, my shorts, my sundresses and even a couple of dressy outfits! I pretty much kept them on the whole vacation and ignored the 10 other pairs I wasted time and space packing. I don’t know what it is with these shoes but even o. Days we were walking really long distances at the beach or on days I was running all over the cruise boat from dusk til dawn, I never once felt uncomfortable in these and felt just the opposite in fact. I often get achey feet too; but it didn’t happen with these. Whether I was strolling the deck, dancing in the club, or standing waiting in long buffet lines, these shoes had me feeling fancy free and footloose.

The best sandals EVER
Size: 8, Color: White Khaki
These flip flops are so so so comfortable. I have bunions and a nerve problems so finding the right shoe is an issue for me. These are the most comfortable flip flops I have ever had the pleasure to wear. I cannot recommend enough how good and natural these feel. They are flexible yet supportive. So far on vacation they have walked miles with me and still in great condition. They are so naturally light weight. I will be buying again for sure

Most comfortable flip flops ever! From day 1!
Size: 7.5, Color: White Khaki
These are hands down the most comfortable flip flops ever. There is no 'break-in' period. The fabric is so soft you forget it's there and it doesn't rub between your toes at all. By the second full day of wear, the foam was starting to conform to the contour of my feet. They feel and look great. The bottoms have a nice triangle tread pattern on them instead of being totally flat so I'm hoping they will still get traction on wet floors like pool areas etc. I got them after nearly doing a split again in my old ones that were a safety hazard poolside.

Nice flip flops
Size: 7, Color: Grey
Nice looking flip flops. They feel good and well made, but I've only worn them for a few hours. The material that goes over the feet is almost too stretchy. I hope they don't stretch out more. I have wide feet and these fit great, true to size. I like the grey color.
