MASTER and SLAVE Connecting Rods

Normally, there are to connecting rods besides each other, but this setup allows a slave con-rod to be mounted as a part of the master connecting rod.

Hello! How are you enjoying summer, guys?

[@EliasSilva-ff7us]

I am from South America and here it is winter.

[@pabitrikalita3940]

We are greatly enjoying summer ,usually I go for long rides in my Suzuki 2 stroke, hope you are also enjoying your summer

[@John-Laird]

Better now that I've watched this video. ;)

[@Damien.D]

Pretty hot here in France, nice to get some fresh air (ie cooler than the outside, and more gasoline tasty) in the garage, in the basement. How's your recovery? (by the way I could watch radial engine cut out displays for hours. Which i actually did at Safran/Gnome&Rhone private museum. Conrods of these engines looks like octopuses, these are pretty "organic" engines).

[@fidelcatsro6948]

Equal in torque for what matters (ie, black lives)

[@Vaettr205]

This is actually happening in music production. Instead of saying master/slave (ie master/slave midi relationships or master/slave tracks) everything’s changing to parent/child. I don’t think anyone’s making a huge fuss yet, I think companies and developers are just future-proofing their products

You forgot another way of putting two connecting rods to a single crankpin. The blade and fork!!! Imagine putting your spoon in between the teeth of your fork. While it may not be as simple as the side-by-side design, it had a slightly shorter block length-wise since it had no offset heads to worry about. Which also helps in simplifying the cam drives. A few notable examples of this are the Harley v-twins, rolls Royce Merlin, and the Merc DB601. One of the few downsides of the blade and fork engine is the increase complexity in con-rod production, and oil circulation issues in between rods.

[@ferrumignis]

I'd like to see that done on a radial engine...

[@electric7487]

The EMD 2-stroke Diesels have used fork&blade rods since they were first built in 1938.

[@randomdriver]

I never thought it before about the stroke length being a different in these types of engines. Learning always something new!

[@calvinnickel9995]

The timing is also different. On a radial the master rod big end transcribes a circle, but the articulating rod ends transcribe an ellipse. This means that the intervals between each TDC and BDC aren’t evenly spaced. Radials use what are known as a “compensated cams” with unevenly spaced lobes for proper ignition timing.. while valve timing is set so it’s an average for all cylinders (since radials use planetary gears and cam rings which share lobes between all cylinders rather than camshafts).

[@calvinnickel9995]

This is what give the radial it’s unique lumpy sound.

[@electric7487]

Yep, all slave rods that are not 180° apart from the master rod will have slightly longer strokes than the master rod. The Soviet T-34 tanks have a 60° V12 that has a master/slave arrangement, eith a 180mm stroke on the master side and a 186mm on the side with the slave rods. The GE 7FDL locomotive engines are at a 45° angle and also use master/slave rods. I know that the pistons on the master rods have a 267mm stroke, but I'm not sure what the stroke of the slave rod pistons are. Maybe something like 277mm?

[@phil955i]

Are we allowed to call them that these days? Careful you don't start a riot ;-)

[@Triplex5014]

I know that SACM MGO engines have master and slave rods and because of the shorter stroke on the slave rod pistons, thinner head gaskets are used to give the same compression ratio. SACM MGO engines are found in older French diesel locomotives.

[@VeraTheTabbynx]

[@nicolasbiette5573]

[@elekl4621]

You should do one about different displacements within one engine, if it exists...

[@alexmonje2682]

I also read that using master and slave conrods produce diferent primary and secondary forces between banks, so you are eliminating rocking couple between banks (but not in the same bank) but creating inbalance of the forces, thats the reason why is not used in most V shaped engines (also because is cheaper to have equal conrods molds when casting)

I'm surprised that we don't have more radial engined things other than airplanes. The engine design seems like it would have efficiencies that other engine layouts don't have.

Can this technology be used for boxer engine

[@VisioRacer]

Interesting question. I think it could, but the pin would be 180° from the master rod, I mean at its bottom.

[@pabitrikalita3940]

@@VisioRacer thanks bro, I think if someone is building a 2 cylinder boxer racing engine then he can use this as this will not only provide very smooth power delivery but also eliminate rocking coupling, thankyou bro for replying my comment it really means a lot to me
