Peak pressure and boost pressure are the same?

In summary, peak pressure and boost pressure are both measures of pressure in the combustion chamber, but they are not the same. Peak pressure is the maximum pressure reached during the power stroke, while boost pressure is artificially increased by a turbocharger or supercharger. Both pressures are important for engine performance, with higher peak pressure resulting in more power and higher boost pressure allowing for more air and fuel to be burned. Both can be measured using specialized tools, but if either becomes too high, it can lead to engine damage and other issues. Careful monitoring and regulation of these pressures is crucial for optimal engine performance and longevity.

Hello,

I am doing my master thesis about "Means to improve the indicated efficiency in internal combustion engines",and this evening reading about Turbo-charging that doubt came up: talking in turbocharger terms,peak pressure and boost pressure are the same?

Thank you in advance for your help!Fernando

No, peak pressure and boost pressure are not the same. Peak pressure refers to the maximum pressure in the combustion chamber during the compression stroke. Boost pressure is the amount of air pressure delivered to the engine by the turbocharger.
 

1. What is peak pressure and how is it different from boost pressure?

Peak pressure refers to the maximum pressure reached in the combustion chamber during the engine's power stroke. Boost pressure, on the other hand, is the amount of pressure above atmospheric pressure that is created by a turbocharger or supercharger to force more air into the combustion chamber.

2. Are peak pressure and boost pressure always the same?

No, they are not always the same. While both are measures of pressure in the combustion chamber, boost pressure is artificially increased by the forced induction system, whereas peak pressure is a natural result of the combustion process.

3. How are peak pressure and boost pressure related to engine performance?

Peak pressure and boost pressure are important factors in determining an engine's power output. A higher peak pressure generally results in more power, while a higher boost pressure can also increase power by allowing more air and fuel to be burned in the combustion chamber.

4. Can peak pressure and boost pressure be measured?

Yes, both peak pressure and boost pressure can be measured using specialized tools such as pressure gauges or sensors. These measurements can provide valuable information about the engine's performance and can be used for tuning and troubleshooting purposes.

5. What are some potential issues that can arise with peak pressure and boost pressure?

If peak pressure becomes too high, it can lead to engine knocking or detonation, which can cause damage to the engine. Similarly, if boost pressure is too high, it can also cause engine damage or lead to other issues such as turbocharger failure. It is important to carefully monitor and regulate both pressures for optimal engine performance and longevity.
