somehow the crankshaft will define the displacement of a specific engine because of its stroke , but if you can't have an accurate LOCUS or BANGO interference fit how you will be able to assess the crankcase volume if you don't have the crankshaft modelled FIRST because the crankshaft dynamics...

what I was meaning is you start with proportions based on feature to bore size ratio, if it is done on cad you float the model with these baselines numbers for each features proportions EX:( like a 3d model of a piston base on a preliminary sketch ) and THEN you crunch the numbers and lock the...

I think I found what I was looking for and it is a really interesting book about cylinder head modeling https://research.brighton.ac.uk/files/4754974/MichaelBates-ClearScan.pdf book title Parametric Design of Diesel Engine Inlet Ports author Michael C Bates there a lot of nice delicious...

just an update on the subject I started up about 3 weeks ago here's a few examples of what I was looking for are those proportion a form or parameterization if so what is the terms used so i can search more info on the subject i am looking for proportions in relation to the bore size (...

All EMD's engine 567, 645, 710 series uses cast steel piston and are floating trunk piston design with only one internal snap ring at the base of the skirt, these 2 cycle diesel engine don't have a intake suction phase like 4 cycles engines does so there's no almost tension on the piston and the...

yep I think I found a copy on the net :)

so now what I need is a non parametric engine design info than ill be able to understand the whole basic picture and yes I agree making a clean sheet engine on a drawing board is a pain BUT they manage to do it in the old days! not perfectly but in reliable way afterward by the way using a...

is there someone here in this thread answering my questions that actually design engine BEFORE the computer age, in slide rules , pencil and paper era ? just wondering because I am sure that major ICE engine have been design on a monitor screen since the mid 70's at least ?

if you take Keith Duckworth who design numerous racing engines for Cosworth I always wonder how he design them. today with all computer technologies and no slide rules or drawing boards, it is a kind of mystery on how they manage to design reliable engines that lasted under tough conditions. I...

AWESOME! finally I have a basic understanding of the process in sequence. so you rough the model by using a baseline parametric data of your internal ( rotating, reciprocating with stress analysis, flow dynamics and thermal analysis for the combustion including moving parts ) THAN you build...

so from what I understand for the cylinder head model drawings is first you start by modeling the combustion chamber and sparkplug location second you model the ports design(length, cross section and locations for both in and ex ) third you model the valves fourth you model the valve guides...

yep those special developement engines are called "Mono-cylinder Test Rig" these engine are use for evaluation purpose only for updating emission certification on diesel or gas industrial engines General Electric use to have one at its R&D center in Nyskayuna NY for evaluation homologation EMD...

yep the famous ford ECOBOOST with the oil pan covering half the cylinder block yep and interesting design no doubt or the STYER M14 and M16 engine are Monoblock and quite an unusual but interesting design no less here's a description https://steyr-motors.com.au/technology/monoblock/...

and what about the cylinder head feature design in which sequence like A then B then C and so on ? so I guess that the combustion chamber would be detail draw first then the ports positions then the cylinder block mounting bolt holes because the placement of the ports wont constraint with the...

I do understand the production side of an engine department with goals, objectives and criteria to meet before the homologations for production that I am aware of those issues my question pertains more to the sequence of event from the initial sketch drawing to the final first detail sets of...

https://www.calum-douglas.com/design/ here's a good link that is of interest I might buy the book when it will be available in that web page there's some really good info but does it have most of the answer that I am seeking for ? the above link is there as an example of what I am interested...

it is interesting to see the ping pong ball effect between different engineering department trying to figure out how the hell are all those parts going to fit together I am sure that there was plenty of Advils in reach to control head aches :) so from what I understand is that the...

ok I finally have a copy from John Manning’s book, Internal Combustion Engine Design, published by Ricardo, 2012. ISBN 978095732920-1 directly from Ricardo engineering :) here's a few question that I still not fully understand especially concerning the "Cylinder Block and Cylinder head"...

BigClive this is one of my taught is that most engine design features are coming either from a legacy prints or a reverse engineer competitor engine scanned in 3D than the features are extrapolated in a way to go around specific details to prevent any copyrights issues ex:( company A engine has...

so basically the time range of completion is when the whole assembly drawings are done from concept to detail blueprints I know casting drawings and detail drawings are two different things, so say the start to finish drawings are we talking about 4 months or a year I am trying to scale that...
