it would be unnecessarily shorter and often, so they are limiting more or less on the spine
Can you give me permission to sign it?Then,
We focus the project first on the data we can already obtain:
axc = 75mmx107mm (definitely point at 75mm to obtain a 1900 tdi definitely more affordable than a 2.2l), cylinder block type vr-vag 4 cylinders to v of 13°, double shaft balance, piston height (I had to change in the plan) 75,20 mm, nominal diameter 75mm, rod 32mmx68,3mm, segments 2.5 mm [- Aspirazione : 40 X 9 X 128,32] [- Scarico : 30 X 9 X 128,32].distribuzione a cascade d'ingranaggi, structure basamento closed-deck, tree motor plate with sequence of bursts - 4-1-3-2.ora, you have to pass as she says to the drawing of external structures but I have to do everything by hand because I do not know how to use programs cad...
calculating both cold and hot mechanics is an arduous enterprise, it is an enterprise for which you need years of experience in addition to graduation, that is, if you say you design a motor to a new graduate, you don't know how to do it, but it's normal that it is so.You're right about distribution, you know? Then, the intention is to calculate the structure on cold and hot mecchanics!
to tell the truth, in the disel is the engine itself the blast chamber.cut...
then, normally in the diesel does not give all this importance to the blast chamber because every particle of gas injected high pressure in contact with the compressed air creates its own flame front that advances, it is not like gasoline.
...
What I wanted to say and that you do not do a thorough study like in the case of gasoline. .to tell the truth, in the disel is the engine itself the blast chamber.
and that does not matter to him is a colossal baggianata.
If you want to get to almost 5000 laps with a disel without being asphytic or smoky it is better that you start simulating rooms with any sw you find around...
Did you size the engine shaft? Are you ready? do not forget that the race must be equal to 2 times the crank radius.You know what? I have to shorten the race!the average speed of the piston that results now is: 107x5000/30000 = 17,83(p.).too high.the shift to 100mm.
What I didn't understand is this: or do you want to thrive in the true sense of the term?I know, in fact established with precision the race, before it was 107, now I think to 100mm, then I step to dimensional the motor shaft. possibly flat, then, and to follow on the choice of the vr-vag as structure of the base. plane we arrive.
Ohhh...:4425:Hello little engineer,
in the sea of numbers you have given, there are no big contradictions, since in the end your design is a collection of features with an approach to search for the excellent.
In reality, when designing, there is not so much the problem of performance research, especially in systems of which we already know everything (or much better), as in the engines of this type, but we look for the excellent according to a series of constraints.
These constraints are usually the cost of design, production, maintenance and recycling. thinking about the great production, there are also aspects of ease of recovery of raw materials and components (often also relationships with suppliers), durability of the components (today you plan to finite duration, others the spare parts would not sell).
returning to more mechanical aspects, another aspect and where and how to use such motor, which are usually the main constraints that the good mechanical designer must consider.
these therefore would be the constraints that you should give (at least some of these), in order to evaluate the goodness of your project (at least on paper), if you want to invent something new, focus on some components and search for a different solution, identifying the merits and defects.
good work and good healing.

because the wankel is too unique and you can't make it diesel!then why not a wankel.. .
Come on, I'm kidding!
Who said that?because the wankel is too unique and you can't make it diesel!
