In a 2 stroke engine the piston itself is the intake/exhaust valve, instead of having separate valves as in the 4 stroke. The odd shape of the piston is the location of these valves.

Why deflected shape of piston in 2 stroke engine?

Well, isn't that just a happy little question! The deflected shape of the piston in a 2-stroke engine is designed to help optimize the combustion process. By carefully shaping the piston, engineers can ensure efficient fuel intake, compression, and exhaust, all working together in harmony like a beautiful painting coming to life. Just like adding a touch of color to a canvas, every detail in the design of the piston serves a purpose to create a masterpiece of an engine.

How does piston head shape affect engine performance?

The shape of the piston head can affect engine performance by influencing airflow turbulence, combustion efficiency, and heat dissipation. Factors such as the dome shape, valve reliefs, and overall design can impact compression ratios, power output, and fuel efficiency. A well-designed piston head can optimize combustion and help achieve better engine performance.


What is the main working cycle of a v8 engine?

Piston's seized in block?

Disassemble it as far as you can then take it to an automotive machine shop. They'll need to magnaflux and bore the engine and head(s) before you can trust it. They'll get the piston out and if the block isn't damaged beyond repair they can help get your engine back into shape.


What is the clearance between piston and cyclender head?

Piston is the device with a cup like shape that fit completely in the Cylinder.


When people say '' that thing got a hemi'' what does hemi mean when they are talking about cars?

A hemi refers to the shape of the cylinders in the car engine. For a car to work it must have an engine. Pistons sit in cylinders. The intake valve opens. A piston goes to the bottom of the cylinder creating a vacuum. It draws in air and gasoline. The intake valve closes. Then the piston compresses the air. Then a spark makes the air and gasoline burn. That pushes the piston down. Then the exhaust valve opens and the piston pushes the exhaust out. Those four steps make the engine work. At the top of the cylinder on a hemi, the cylinder has a hemispheric shape. For years, hemis, produced more power than other engines the same size.


What is mean engine V8 4.7 L?

The internal combustion engine has 8 pistons. Two rows or "banks" of 4 pistons at an angle to each other to form a "V" shape. The displacement of the engine (the size of the combustion chambers of all piston cylinders added together for the entire engine) is 4.7 liters.


What can you replace a piston with that is not a different piston but an object that is not a piston?

The general term for piston is cylinder, and a cylinder might be made to work in this application. But a cylinder used in this manner, that is, a cylindrical shape connected in a machine that is used in the same way will almost certainly be called a piston by most investigators.


What is the most important part of an engine?

Depending on the type of engine, piston, turbine, external, rotary, among others there are numerous components to an engine without which the engine will not function. For example a typical piston cylinder engine(from any car) will not work without any of the following components-piston, carburetor/fuel injection, con-rod, crankshaft, inlet/exhaust valves, camshaft, camchain/timing belt. An engine is a complex device that requires many finely balanced components to work in harmony. But to pick the most important, it would probably be the crankshaft which is present in any type of engine in some shape or form.


What determines piston stroke?

Both con-rod length and shape of the crankshaft affect piston stroke


Will it hurt if piston rods go back in different than before rebuild?

Yes, if piston rods are not installed correctly during a rebuild, it could cause engine damage, poor performance, or even complete engine failure. It is crucial to follow the manufacturer's specifications and ensure proper alignment and torque settings during reassembly.
