1. Engine Capacity: Engine capacity, also known as engine displacement, is the total volume of all the cylinders in an engine. It is calculated using the formula:
Engine Capacity = (π/4) x B^2 x S x N
Where: - B is the bore of the cylinder (diameter of the cylinder) - S is the stroke of the piston - N is the number of cylinders in the engine
2. Compression Ratio: Compression ratio is the ratio of the maximum volume of the combustion chamber to the minimum volume of the combustion chamber. It is calculated using the formula:
Compression Ratio = (V1 + CV) / CV
Where: - V1 is the volume of the combustion chamber when the piston is at the bottom dead center - CV is the clearance volume (volume of the combustion chamber when the piston is at the top dead center)
3. Clearance Volume: Clearance volume is the volume of the combustion chamber when the piston is at the top dead center. It is calculated using the formula:
Clearance Volume = (π/4) x B^2 x S
Where: - B is the bore of the cylinder - S is the stroke of the piston
4. Piston Displacement: Piston displacement is the volume of the cylinder swept by the piston during one stroke. It is calculated using the formula:
Piston Displacement = (π/4) x B^2 x S
Where: - B is the bore of the cylinder - S is the stroke of the piston

Engine Capacity (Displacement)
``` Engine Capacity = (Bore Area × Stroke) × Number of Cylinders ```
Where:
- Bore Area = π × (Bore Diameter / 2)² - Bore Diameter = Diameter of the cylinder bore in mm - Stroke = Distance the piston travels from top dead center (TDC) to bottom dead center (BDC) in mm - Number of Cylinders = Number of cylinders in the engine
Compression Ratio
``` Compression Ratio = (Total Volume of Cylinder) / (Clearance Volume) ```
Where:
- Total Volume of Cylinder = Engine Capacity + Clearance Volume - Clearance Volume = Volume of the cylinder when the piston is at TDC
``` Piston Displacement = (Bore Area × Stroke) ```
Where:
- Bore Area and Stroke are defined as above

HOW CAN I RECOVER MY LOST BITCOIN
Hello to everyone. I'm so delighted to be able to share this story with you all. I was involved in a bitcoin trading scam, I came across a company website that promised a big return on investment. I put 850k USDT in an online cryptocurrency investment platform and I was scammed out of everything. When I went online, I found a piece advertising GEO COORDINATES HACKER hacking collective with a reputation for recovering cryptocurrency, that had received a lot of favorable feedback. I decided to get in touch with them, I contacted GEO COORDINATES HACKER, and submitted my case to the expert. My experience with GEO COORDINATES HACKER. A Certified Crypto Recovery Expert who helped me recover my funds. If you are a victim looking for a hacker to help you get your money back. You can have a chat with him on his Email:
