Hi all,
My problem is a question from my coursework.
The question is;
We are to inject propane gas into the diesel engine of the Vauxhall Omega on a dyno run.
Calculate how much gas is required to give the engine 60nm more torque?
obviously i can appreciate some people may not want to answer the question for me and that's not what I am after, i know how to calculate torque from cylinder pressure using piston size, swept volume, clearance volume etc. BUT the problem i have is, i can't find any info on propane gas injection and the sort of numbers i will have to factor into my equations.
The car in question is also a 6 cylinder vehicle so calculations can be made for 10nm per cylinder.
Any help or guidance will be greatly appreciated
Many thanks,
Liam
