Crankshaft of Engine Questions:

Question #1:

Has any effort to harness the waste heat of an internal combustion engine been successful?

I conceive this should be the "Holy Grail of Automotive Engineering".

I wager the BMW Turbosteamer. Uses a steam turbine to harness squander heat from exhaust.
Built and tested. Not produced yet. Could be fitted to some BMW.

The Crower 6 wheel engine. Injects liquid to create a "Free Powerstroke" for each fueled powerstroke
Prototype Built by Bruce Crower of Crower Cams.
Reported to be so efficient that it requires no chilling system.

The Troop 4-2-4 Gasoline/Steam Hybrid.
This engine uses heat and push from digit 4-stroke fuel cylinders to noesis a
third cylinder, which is a 2-stroke clean engine streaming on the same crankshaft.
No prototype has been built for this engine.
Lacking R D capital, the inventer Gerald Troop gave it as a gift to the world.
Anyone haw develop this as they gratify without limitation.

Are there others? Have some gone into production?

Question #2:

Car issue after engine rebuild..?

2004 Mazda 3
2.3 hatchback
5 speed.

So this is what i did
I removed the engine due to rod knock/welded bearing

Did a rank rebuild
flywheel
clutch
Balance shaft delete kit
Cos-worth Crankshaft
Rods
bearings
head gasket set
seals etc
but i didn't change the lubricator pump

when everything was said and done it started correct up and ran rattling smooth and good, no leaks, no smoke from the exhaust.. everything meet perfectuntil..

My Problem is this..

When i start the car and leave it running, it runs smooth and works perfect,, it revs well and runs at indolent 700-800rpm

When it hits operating temperature it runs almost same its onset the spark at the criminal instance on digit of the cylinders and it starts clunking and squealing a little likewise substantially i never let it running long enough to analyse it out i ever invoke off at that point...
and also when it hits operating temp i cant rev even when i rev it, it just starts obstruction and running rougher.

No overheating
The oil pressure from a machinelike judge is 80 psi on algid move and settles at 30 psi after it warms up....

what could this be?
I undergo i didn't change the lubricator viscus as i was questionable to but the feeler gauge was within specs..
I have Changed every part except the pistons, rings and lubricator pump...

Question #3:

ALGEBRA 2 please help! Im so freakishly confused?

This word difficulty is insane
I meet need someone to support me cipher it!

PROBLEM : In an interior oxidization engine, the up and downbound motion of the pistons is regenerate into the rotary change of the crankshaft, which drives the flywheel. Let R sub one represent the radius of the flywheel at the right and let R change 2 represent the radius of the crankshaft expiration finished it. If the formula for area of a circle is A = π R 2, write a simplified, factored countenance for the Atlantic of the interbreed country of the flywheel outside the crankshaft.

Question #4:

A mathematical word problem?

I hate these, and i really do not see this one. Please help. Thanks so much!

PROBLEM : In an internal oxidization engine, the up and down motion of the pistons is converted into the rotary motion of the crankshaft, which drives the flywheel. Let R change one represent the radius of the flywheel at the correct and permit R sub 2 equal the length of the crankshaft passing through it. If the instruction for Atlantic of a lot is A = π R 2, indite a simplified, factored expression for the Atlantic of the interbreed section of the flywheel outside the crankshaft.

Question #5:

Do i have to 0pull my trans to get to my crankshaft position sensor?

1996 automobile noble cherokee limited 5.2ltr v8 replaced the trans and I conceive I brokethe device in the process. The device is located on backwards of the engine country in the bell housing. Pleas tell me there is an easyier way? Thanks
I woulda asked you but I'm on my barrier sound and I jus figured out I had to change it to screen to be able to add details. Lol. I don't think it module go up that broad wil it?

Question #6:

Is this an improvement on the Crower 6 stroke engine?

Bruce Crower of Crower Cams built a very efficient engine my adding an injection of liquid after the wear stroke, allowing a "free" player noesis stroke, supercharged my steam.
The engine is so efficient that it doesn't need a chilling system.
He built digit that works and greatly improves efficiency, but I doubt it will ever go into production cod to longness problems.
Water and valves seen incompatible to me.

Is this engine an improvement?
I call it the Troop 4-2-4 engine.
It is a 1000 cc 3 chamber engine.
Both end cylinders are 250 cc's and 4 cycle,
streaming on pedal or diesel.
The 500 cc edifice chamber is 2 stroke, streaming on steam, and powered by the modify from the exhaust of the digit quaternary stroke cylinders.
Every engine revolution gets digit oxyacetylene noesis attack and one "free" clean noesis stroke.
By using the push of the exhaust, it is doable to separate the 2 stroke clean chamber on the aforementioned lubricator bath crankshaft as the gas fired cylinders.
And since the 250 cc pistons run in tandem, fired 180% apart, the 500 cc piston balances the crankshaft.
Since this engine is most efficient at flooded throttle against a static load, I study it an ideal auxiliary engine in an extended range automobile vehicle.

Question #7:

Can you put a Shindaiwa t261 String Trimmer engine on a Go-Ped Sport?

Hi
I bought a Go-Ped Sport not response Sport soured craigslist for 70 with a Craftsman/LEHR Eco-Trimmer engine installed. It had the clutch distant and a spindle mounted with a propellor inside the crankshaft. The problem is I crashed the Goped and poor the engine rattling sharp lol and today I was wondering if i could mount a spindle or something to behave same a spindle ex. cycle prosthesis onto the crankshaft of a Shindaiwa t261 String Trimmer engine. The mounting holes seem to distinction up but I dont undergo if its doable to add the spindle. Could anyone tell me how to do this or if it is even possible?

THANK YOU!!!!! :



And meet to address the discourse of WHY the hell I am doing this... heres the reason: I institute this trimmer cheap on craigslist and it gets surpassing fuel economy and great performance according to most gardeners and also based on specs from website...my own gardener even has one! lol . And also because Zenoah Komatsu engines are so expensive!

Question #8:

Would you call this a 3-stroke engine?

2,4, 5 and 6 wheel engines hit been built.
This is a hybrid 4 cycle fuel and 2 cycle steam engine.
Average the two and call it a 3-stroke.

I named it the Cappuccino engine, but a Suzuki Cappuccino automobile was built and not imported to US.

A 2 stroke uses no cam driven valves. It relies on piston function to modify intake,compression, power, and wear in a single revolution.
A 4 cycle requires 2 revolutions of the crankshaft to produce one power -stroke.
Ordinarily, a 2 stroke draws a fuel/ air/ oil mix thru the crankcase.
This is unnecessary in this case.

With a 2 stroke, every down-stroke is a power stroke.
With a 4 stroke, apiece ordinal revolution has a noesis stroke.

This engine utilizes wear push to feed the 2-stroke cylinder, so it is possible to run it on the same crankshaft as the digit 4 cycle pistons.


The exhaust pedal is fired into the edifice intake port on each exhaust stroke from both fuel or diesel cylinders.
A taste of liquid is then injected into the cylinder and the compression and heat then produce steam, creating a power stroke.
Since the clean power stroke is fueled all by squander heat, for every liquefied oxyacetylene stroke, it gets a "free" power stroke from steam.
Furthermore, the wasteful process of pumping coolant and displacing modify by radiator is unnecessary.
By placing he 4 stroke pistons in tandem, and fired 180 degrees apart, the crankshaft is counterpoised and the pistons are positioned to blast the exhaust gases into the large down touching steam cylinder.
The center cylinder, which is a 2 wheel steam engine, is twice as super as the 2 end cylinders, which are 4 cycle gasoline.
It is positioned 180 egrees oppositeness the pair of 4 stroke pistons. This balances the engine.

Any think it wouldn't work?

Compression creates heat in constituent to the heat of the previously fired cylinder.
There is no way that this waste modify would be insufficient to display clean power.
Actually, this was never intended as a bike engine.
I placed it here because MC guys understand 2 strokes.
It was designed as a motorcycle fourpenny helper engine for an long arrange automobile car.
It would separate at flooded throttle against a static alluviation to separate a generator.

Question #9:

Is a gas/steam hybrid engine feasible?

Would this gas/steam hybrid engine work?

Most everyone knows that interior combustion engines must display squander heat.
See Carnot Principle.

BMW fashioned the Turbosteamer to command this heat, which is pronto acquirable at the wear port.
Bruce Crowder of Crowder Cams fashioned a 6 attack engine using injected water to create a "free" powerstroke.

I declare the Cappuccino Engine.

This is a 3 cylinder engine with both modify cylinders existence pedal or diesel 4 stroke interior combustion.

The third piston, twice the size of the another two and operative on the same crankshaft,
would actually be a new kind of engine that I call an
"Internal Compression Steam Engine".

The digit 4 cycle pistons would be positioned in tandem on the crankshaft and fired 180 degrees apart.

The larger edifice piston would be positioned between them and would be 180 degrees oppositeness them for balance.

It would be fueled by the wear heat from the digit diesel or gas fired cylinders. And the wear push contributes to the function of the engine.

It would be 2 cycle, so every down-stroke would be a Power Stroke.

By production up push and modify from the exhaust ports of the 2 modify cylinders, this 2 cycle clean chamber does not need to draw intake gasses into the crankcase as a connatural 2 attack would.
This allows a the edifice cylinder to duty as a very differant identify of engine.

I do not believe a 2 cycle steam engine hs been created.

By using the squander heat as render and blowing spent steam thru cooling ports, the larger ordinal chamber produces a "free" powerstroke for every conventional powerstroke.

And no liquid pump and radiator are required.

I am the inventor of this engine.
I provide it to world to amend as you gratify without regulating or charge.

Gerald Troop
For Clarity---

Water is injected on every attack of the edifice cylinder.
This was not doable preceding to high push render injection.

Note that the 2 end pistons are positioned in tandem and FIRED 180 degrees apart.
A 4 stroke engine is fired every 2 revolutions.
It actually does have a supine cooling system.
First, such heat in converted to power.
Second, spent clean wear is blown thru cooling ports.
This physically carries modify away with apiece turning of engine.

Question #10:

will a 200ft. lb. 19.2v impact wrench remove a crankshaft bolt on a saturn sl2?

i can't intend the crankshaft bolt out i tried the wave forbid and socket and the engine crank method but null employed so i purchased a artificer 19.2v impact motion today. It is rated at 200 ft-lb of force and 0-3000 Impacts per time IPM . will it remove the unstable bolt on a 1.9 DOHC saturn engine?
even if the impact doesn't support i crapper still ingest it for tire changes and clog like that so its rattling not a Brobdingnagian waste. i will go and get a wave forbid and tube tomorrow.

Thanks for every the answers
