A 4 stroke gasoline internal combustion engine operates on a 4 stroke cycle, hence the name, "4 stroke engine". The first stroke is the intake stroke, the piston moves down the cylinder, which creates a vaccume, which draws in fuel and air from the induction system. The second stroke is the compression stroke. The piston starts at the bottom of the cylinder and begins to move up, compressing the air and fuel mixture. Just before the piston is at the top of the cylinder (top dead center), the spark plug fires, igniting the compressed air and fuel mixture. The resulting explosion causes the 3rd stroke, the power stroke. The force of the explosion pushes the piston back down the cylinder, turning the crankshaft. The 4th and final stroke is the exhaust stroke. After the power stroke, there is exhaust gas left in the cylinder. The piston moves back up as the exhaust valve opens, pushing the gases up the cylinder and out the exhaust. This cycle continues thousands of time per minute as the engine is running. If anyone was wondering, a 14 year old wrote this explanation.
It is called the compression stroke.

Remove all the spark plugs and turn the engine over by hand. Place your thumb over the #1 plug hole and you will feel the pressure on the compression stroke. A compression gage will also tell you when you are on the compression stroke.
The intake stroke is the first phase of the four-stroke engine cycle, during which the piston moves down the cylinder, creating a vacuum that draws in an air-fuel mixture through the open intake valve. This process prepares the engine for combustion by filling the combustion chamber with the necessary mixture. The intake stroke is crucial for efficient engine performance, as it sets the stage for the subsequent compression, power, and exhaust strokes.
It was considered to be the First modern Engine. By modern Engine, they mean the first four-stroke engine.
1886 - Karl Benz received the first patent (DRP No. 37435) for a gas-fueled car. 1889 - Gottlieb Daimler built an improved four-stroke engine with mushroom-shaped valves and two V-slant cylinders. 1890 - Wilhelm Maybach built the first four-cylinder, four-stroke engine.
With the middle cylinder, its in between the 2 cylinders causing it to become more hot. thats generally why that happens.
I had a 1974 Suzuki 750, it was a two stroke and I believe the first water cooled motorscyle. It was called a Water Buffalo. Honda 750 Fours were the hot bike of the day and this motorcycle would WALK away from them in a race. Mark Malatesta maico make a motorcycle with a single cylinder 700cc two stroke gas engine

when the piston moves up in two stroke engine first of all it covers the scavenge ports and then when it moves little bit up then cylinder lube oil is injected between the piston rings. when it further moves and compress the scavenge air and the temperature of the air inside the cylinder increases above the auto ignition temperature of the fuel oil. and before the piston reaches TDC the fuel is injected and hence the combustion begins.
