    Forces Gas Peak
AI Thread Summary
To calculate peak gas force, the formula used is Peak gas force equals pressure multiplied by bore area. The maximum cylinder pressure for gasoline engines is not universally defined, as it varies based on engine design and operating conditions. Diesel engines typically have a maximum cylinder pressure of around 180 Bar, but this figure is not applicable to gasoline engines. The discussion highlights the complexity of determining pressure due to numerous influencing variables. Accurate calculations require specific data for the gasoline engine in question.

Hello, guys

I am fresh, I have a problem about my calculate. I know Peak gas force=pressure*Bore Area

however how to calculate pressure. I knew diesel car max cylinder pressure is 180 Bar, but I do not gasoline car max cylinder pressure.

Could you help me solve this problem?

Far too general a question. There is so many variables to consider. How do you 'know' that diesel max cylinder pressure is 180bar?
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'What type of toilet do I have?'

Thread 'What type of toilet do I have?'

I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...

Thread 'Thread No-Go plug gage allows 3 turns to enter. That's too many!'

After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
