@d4a Imagine how precise the worm gear drive positioning would have to be to keep all the planetary gears, and therefore the crank, in line so there isn't any offset and induced warping.

Absolutely agree with the pros and cons of the engine - relatively simple and easy to build and fit in a future 911, but the balancing problem is there. I am not into Porsches, especially 911s (probably because the main thing for the every new 911 is - how much Porsche can change it without changing it), but the patent looks like it's absolutely feasible and can be executed.
@budthecyborg45752 сағат бұрын
If you only have efficiency gains at high load then this is the least useful upgrade versus hybrid power. Hybrid assist allows you to generate high torque for acceleration without using high boost pressure, thus the rich fuel mixture is avoided and a hybrid engine already doesn't have the problems that the six stroke aims to solve. Basically this is just an elaborate way to lower emissions on performance cars without using a hybrid drivetrain, which is an admirable goal since this should have lower long term maintenance cost, but the added up front cost means this engine will probably never be deployed in passenger cars.

The main issue I see with this design is the wear on the crankshaft gears. Everything else is kinda fixable, you could have another either electric or camshaft actuated intake valve before the bdc2 intake holes to prevent the need for the piston to be half the length of the zylinder, you could run different intake pressures to precisely measure how much air would get replaced during scavenging, so for example run a turbo for the main intake system and a compressor for the bdc2 intake system. But I really can't think of any material that can withstand the forces transferred on these gears at a few thousand rpms realiably over a longer period of time. Plus, the wear of these gears ends up directly in the oil, plus, to service them you have to replace the entire bottom of the engine, the crankshaft itself, all the additional parts like connecting rod bearings etc...
@lasskinn4742 сағат бұрын
there's other problems like you need to have forced induction anyway so that the exhaust doesn't exit through the extra intake ports - or vacuum at the exhaust side, it doesn't just happen automatically. the benefits are largely unproven as well and sound quite sketch for efficiency, everything would need to make up for the losses in the gears. the "more power" is kinda irrelevant without anything actually to back it up and like said it needs forced induction anyway (at all rpm's not just at low like d4a says, they become the exhaust ports of a 2 stroke engine at the bottom if there is no positive pressure higher than the crankcase pressure)

It should more or less balance out for 3 cylinders, not unlike 3-phase electricity. However, it would balance still better for 3 pairs of cylinders, which you mentioned :) Two question, though: first, you modeled the 180° offset. In 4-stroke design it's the only one. However, in 6-stroke you can also consider a 540° offset. Would it balance better or worse? Second is not as much a question as a vague concern. The five-lobe structure of this hypocycloid is bugging me, telling that there should be something going on with five-way division. Any thoughts on this?

Seems this design was done by mechanical specialists not by alternation of load guys. The design parameters to adjust the 3rd and 4th stroke-scavenging are the exenter, the liner scavenging cross section, bore size and maybe some sophisticated kinematic lengthening the 2nd BDC duration (not added to the patent yet). At BDC on full load one can still expect 3-15 bar of exhaust gas pressure, the time to release it by the exhaust valve a part of it, which is high enough that the scavenging can act on boost pressure level depends not only on the alternation of load setup, the turbine and compressor map matching but also on engine speed and load. These are the chains around the combustion process design, to get the scavenging done. It's very likely there will be an additional demand for intake boost for a wider range of engine speed and load. For an daily driver you can thing of an mechanical compressor, or you need a high voltage battery driven compressor to feed just the demanded energy in it. This 6-stroke-engine my work for single operation point applications like combined heat and power (generator, one speed, one load point) or range extender (one speed and some load variaty), but the challenge to get it done for an full mobile application is costly and the result is likely more inefficient then a 4-stroke-contender. A Porsche application, if they don't jump into the CHP business, may be a range extender system to hybridize a BEV applicaion. I have my doubts we will see Euro 7 matching 6-stroke-engines from Porsche. By the way, in Germany we don't shorten or bend the Sir name, we may shorten the name. That's why Ferndinand Prosche may got called Ferdl, but not Porsch. You may call it Porsch and everyone understand it in the english speaken areas, but it's disgusting for me to bend someones Sir name like you like it best. The name of the Company is Porsche. No bending, no shortening, no trivialization, it's only Porsche. I work on Porsche race engines from 60'ies to 80'ies, from B6's to V16's, from 2 Liter to almost 7 Liter, these are amazingly engineered 4-stroke-derivates, very robust, quite innovative for their time and dominating in performance and endurability almost all racing classes. I appreciate that and take my hat off for these engineers and mechanics running these to great success and today's position of Porsche, they never would had if Motorsport's would not have that successfully. Motorsport was Ferdinand Porsche's main driver for the engineering, innovation and performance of his products, since his first engine/car. If you honor that, call it Porsche, if not, call it what ever you call it.

I love this concept and how they're pushing ICE. I wonder how oil blow by and consumption is going to be with this design. Wouldn't the ports at the bottom of the cylinder allow oil to get into the combustion chamber? They've obviously thought about this, but I'm curious about their solution for it. Either an extra set of valves and an acceptable amount of oil burn, or some wild piston rings that do something tricky when going past the ports. Cool Stuff.
