The Elio Engine

The two-step valve lift system sounds kind of like the step timing system they came out with for diesel engines. Not exactly the same thing but same basic idae

In the interview with Paul Elio at the factory it was report they had cleared one of three hurdles with the loan.

So the Engine Block is now assembled. The next few tasks sound more like I expected, volumetric, pressure and leakage checks.

TekTalk: Now that we have the majority of these parts machined, we are ready to put together our first prototype and test it using a dynamometer. The first step before going on a dynamometer will be to make sure the engine is ready to run. This involves making sure the engine spins freely, holds water, does not leak and maintains proper oil pressures. The next step in the process allows us to run the engine through a variety of simulations to test force, power torque and combustion behavior, and test how the Engine Control Unit performs. These simulations will include both city and highway driving conditions to see how the engine performs at various loads

I would expect the conference on the 7th to see the full engine, but Dyno testing maybe delayed until afterward. It would be much nicer to see some Dyno results for that actual conference, since those industry people consider it 'proof in the pudding' validation. Hopefully by the 7th is enough time for at least one test run, unbolt and airship to the conference!

Here is the fully machined and test fitted engine:

Does it look to you like it has sleeves?

It looks that way because it does.

It has been reported to us that this initial prototype engine uses traditional steel liners and does not have any variable lift or timing mechanisms installed. This is apparently done to run the engine at a baseline level and then add variables to it as development and testing continues to measure the resulting differences in the engine performance.

It has some nice attributes compared to both Turbo and regular super chargers. But one problem, using electric 100% would mean an efficiency of 7% (for the power used by the booster), the same as the typical serial hybrid cycle. So this is slightly more for power rather than efficiency. That is to say it could make a 300hp get the same efficiency as say maybe a 200hp. But , IMO, the lower the HP application the benefit may be less interesting.

But if it had a turbo feed in parallel to electric then it could be suitable for even higher efficiencies, and very-very efficient while also controllable even from dead start. Such a system may even be trimmed to do a little 'bottoming cycle' based on the exhaust gasses.

Just some Imagineering.

So we have an Engine at least enough now in one place to call it one. I wonder if it will stay sleeved or not. Next big day is when they drop it in the P4 and run it around the block a few times.

I don't think that is going to happen. The P4 is too busy being the guest of honor at all the events. LOL They will need a different vehicle for that. :-) Z
