How to Find A Petrol Engine Engine

This is one of the more challenging tasks a petrochemical engineer will have to tackle.

You are looking for a gasoline engine that has an engine block that is both solid and water-cooled, as well as a piston and cylinder head that are both steel. 

A solid piston, the piston and its cams can withstand a great deal of pressure, while a water-dammed cylinder head can only withstand a very slight amount of pressure. 

Once you have all of that in place, you can look for the piston by finding the side of the cylinder head with the cylinder cap removed.

You can also find the piston head by lifting the cylinder out of the engine. 

If the cylinder is solid, you will need to use an external camshaft. 

It should be noted that many engines require a special tool, such as a socket, to remove the piston. 

You will also need to know the engine’s power rating.

If you have a car engine with a V-6 engine block, you may need to measure the engine pressure in order to determine how high or low the fuel pressure is.

You will also want to know if the piston has a camshank that is flush with the face of the piston, which will be necessary if the engine is to be water-damaged. 

In most cases, it is best to use a car shop to perform the test, and in rare cases, a professional carsmith to do the job for you. 

The following is a general guide on how to determine the engine block of a petrol engine.1.

Determine the size of the block.

This will determine how large the block is.

A small block is generally easier to measure, and usually has the correct dimensions. 


Measure the diameter of the valve.

For a standard cylinder head, measure the cylinder face with a pencil or ruler.

A smaller diameter will not necessarily mean a larger valve.3.

Measure out the pressure and cylinder pressure in grams. 

This will determine the pressure of the combustion chamber, and the cylinder diameter. 


Measure in milliliters.

For the valve diameter, measure from the base of the baseplate to the tip of the head.

A larger diameter will generally mean a smaller valve.5.

Measure pressure and the air flow in grams per square inch. 

An accurate pressure measurement will determine if the valve is dry or wet.6.

Measure air flow per inch in millimeters.7.

Measure a pressure reading in feet per square meter. 


Measure cylinder pressure by dividing the pressure reading by the diameter.

For example, if the cylinder pressure is 8.6 pounds per square inches, divide the pressure by 8.4 to determine pressure.9.

Measure displacement in inches.

For displacement in milliliter, divide by 10 to determine displacement in feet. 


Measure engine speed. 


Measure horsepower by multiplying the horsepower reading by 10.12.121212.
