Has the internal combustion engine peaked?

Diesels are maxed out, modern diesels are way over complicated thanks to emissions controls.

The gas engine is probably pretty close as well.

Now even Europe is turning against diesels.

Diesels have been absolutely ruined. The days of a reliable, efficient mechanical injection diesel are gone. Now it's some emissions-[censored] loaded p-----g contest for torque bro contest thing.

Yup, this will be a large step forward in efficiency when perfected.


Seems like it should satisfy the greenies. Very low NOX and soot emissions.
 
Pretty much, the last diesel car I'd buy is a 2005 E320CDI. Proper I6, mechanical, 40mpg...

These days a new E class diesel with all the [censored] on it can't beat it.
 
Seems like Toyota has achieved remarkable thermal efficiency with gasoline engines. I'd guess the 40% limit is about it for the small gasoline ICE.

FWIW, the largest diesel engine in the world peaks at 51.7%. The theoretical ideal is 56%. However, those engines are so large, they are naturally efficient by virtue of size, thermal loss and friction related issues.

As stated hcci will be a jump in the right direction, pneumatic or solenoid driven valves will allow for infinite variability of valve timing
CNG is also great for the ice. Super clean burning, oci can be stretched even further. The CNG civic was even fun to drive. The Honda insight engine was full of little tweaks for efficiency. And it did well.

Weight and epa mandates are what's killing fuel efficiency

With ever increasing pressure for stricter emissions worldwide, have ICE's reached its peak?

Could hybrids still work, or are we basically looking at all electric cars in the near future?
Self serving remark. Go back for some more Federal grants, Musk. Maybe, someday, you'll turn a PROFIT without the Feds propping you up.

EPA and the safety Nazis.

The demise of the ICE has been talked about for a long time. At this moment it’s still far from imminent.

It might be surprising what could be done with fuel efficiency if emission and safety requirements were frozen for a dozen years or so. When you are required to spend money developing solutions to new emission and safety requirements on a continual basis, it diverts resources away from other things like fuel efficiency.

Like it or not, we have what we have in the way of vehicles largely because of government regulations. If the auto industry was left to it’s own, the product offerings could be much more varied.
 
Both diesel and gas engines have had emission equipment for years. Blaming the VW scandal on engine design peaking is stupid. They could have installed the proper emission equipment but that would have made them more expensive and not as competitive with the competition and gas. Cheating to stay competitive.

I know where we could mine hydrogen. It's mixed with a little helium but we need that too.

I mean it's right there in plain sight. I can see it now.

It's a little cloudy here, can't see it. It's a little hot & far away, though! I thought most hydrogen was derived from electrolysis from water? Or is it from natural gas?

Most hydrogen is produced from hydrocarbons. Deriving it from the oxide is a pretty big thermodynamic hill.

The current Tesla EV's, Model S and X, are to generate revenues for next vehicle Model 3. This Model 3 is supposed to cost about $35k and will be in production by mid-late 2017. This Model 3 is the car that will show if Tesla will be able to survive or not.

EV is new therefore infrastructure are not as abundant as gas/diesel stations. Tesla is expanding their fast charge stations in US and some oversea countries. There are some destinations(hotel, restaurant, shopping center ...) with chargers onsite. As EV sale increases more charging stations will be built. As of now, EV is not as convenience as gas/diesel vehicle for long trip. But thing will change in future.

His electric car business is running at a loss, but carbon credits are pure profit for him. Tesla is the overhyped prostitute of Wall Street.

Do you know profit margin of Model S ? Compare with other luxury makes/models ?

Musk knows all the revenues that he can get with an EV, he started Tesla with a business plan just like every other investor, total revenues minus total cost is profit (or lost if spending is more than taking in).

The reasons that Tesla is reporting losses are cost of expending his company is more than revenue from Model S.

If you take into account cost of developing a new vehicle (Model X for Tesla) is in billion(s) dollars, also cost of building Mega-Factory to make battery is billions dollars. You will see why Tesla is and will be loosing money the next few years.

Tell me a current large corporation that didn't loose money the first few years when they started. Did FedEx make money the first 3-4 years ? Did Amazon earn a profit the first 5 years ? and do Amazon have any full year profit after 15 years ?

When did Tesla receive Federal grants ? How much were those grants ? As far as I know Federal didn't grant Tesla 1 penny.

Tesla received Federal loan guaranty in around 2008-2009, they paid it all back plus interest more than a year ago. They did much better than all Federal guarantied loans to all other companies that last 20-30 years.

_______________________________________________________

As far as I know, Tesla didn't break any law, everything they do so far are not immoral nor unethical. They did every according to standard business practices.

They are stand out from the crows because their products are better than anyone can imagine just few years ago. They are the leader in EV segment, they set the bar very high for anyone to follow. The best traditional car manufactures don't have any answer to Model S as of today, only have some vehicles on drawing boards to compete with Tesla 2-3 years later.

With this you should applause Tesla, a new/star up company that set the stone for Mercedes-Benz, BMW, Audi, Porsche, GM, Ford, Toyota, Nissan ... to follow. Without Tesla do you think that big luxury German car makers would be able to plan for an EV with 300 miles range ?

I figured we'd already have pneumatic or hydraulic valve actuation by now.
Once valve timing isn't limited by a cam it opens up a whole new world of possibilities.
You could have stump pulling torque right off the line,and spin it to the moon
Once the cam is eliminated what will be an engines limiting factor. Piston speed,vibration?
 
HTSS-TR, good points, but I think many of the folks commenting are still lamenting the move to fuel injection so I expect it to fall on deaf ears.

As far as electric go, well no matter what electrics just don't have the range. Battery technology is moving rapidly, but it is still a LONG way from packing as much energy into a space than gasoline.

As a fanatical fan of everything that makes motivation through contained explosions, I am looking forward to electric cars. Can you imagine the fun of a sports car with individually driven electric motors at each wheel? It will probably be tamed down to keep it from pulling your eye balls out o the side of your head.

Name an auto maker that hasn't been propped up by the Feds. US, Japanese, and European makers have all had help. Why single out Tesla?
