Not Yamaha related - yet.
A few months ago, Koenigsegg's FreeValve announced the development of a camless engine together with Qoros Auto. Now, the technology has made its debut at the 2016 Guangzhou Motor Show.
Using the company's Pneumatic-Hydraulic-Electric-Actuator, instead of the traditional camshaft-based method, the unit is the world's first FreeValve engine intended for mass production.
According to Koenigsegg, the 1.6-litre turbocharged engine will develop 230 hp and 320 Nm of torque, offering a 47% increase in power, a 45% increase in torque, and a 15% percent increase in fuel savings compared to a similar traditional engine. Moreover, the unit is 20 kilograms lighter, more compact, and (presumably) cheaper to manufacture, as it misses a throttle body, a camshaft, the timing gear, pre-catalytic converter systems, direct injection systems and so on.
"FreeValve technology has taken many years of testing and refinement but the results are extremely satisfying. This production-intent engine offers Qoros significant savings in emissions, cost, and weight. It also offers groundbreaking benefits to vehicle owners in terms of a near 50% increase in both power and torque, while actually reducing fuel consumption", said Urban Carlson, CEO of FreeValve AB.
The engine was showcased on a Qoros 3 hatchback, as the Chinese car maker will use a fleet of test engines to further develop the technology.

Nice breakthrough for motorcycles. How about a 350 lb FZ10 with 200 hp and gas mileage in the 50s?

Interesting technology. Hopefully it will carry into all internal combustion engines.

jalopnik.com/what-its-like-to-ride-in-a-car-with-the-camless-engine-1529865968As much as I like internal combustion engines, I feel the future will be electric motors. The ability to make instant torque with 100+ mpg equivalent fuel mileage is just a better technology. Tesla model S is rated at 700+ horsepower and 100mpg. Gas engines just can't compete sadly. Personally I'm torn as person that actually enjoys driving/riding. The sound of gas engine, the feeling of nailing a downshift into corner will all be gone with electric.

Don't forget about the energy and resources to produce the battery, the energy to power it and the energy to recycle it. There is also polution connected will all of that, so it's not simply pure, clean, cheap energy. Like the scientific expression "energy in equals energy out".
And I totally agree with the sound. I watched a video of the latest average speed record for motorcycle at Isle of Mann running an electric motor. I wouldn't care if he averaged 500 mph, it was boring. RPM changes, upshifts, downshifts in a gas engine are adrenaline producing music to the ears.

Personally I'm torn as person that actually enjoys driving/riding. The sound of gas engine, the feeling of nailing a downshift into corner will all be gone with electric. I agree that alternative energy engines will be the future as well. However, the issue at hand is the batteries themselves. Once we can have the range of 1000 miles on a charge, and or the charge time in under 1 hour from empty to full, we are as far as we are going to go for now. That being said, one issue with silent vehicles is the safety concern of being unaware. I believe the industry is covering this as we speak with intelligent cars getting better every year at detection and notification. Once they nail that down, I believe they will put almost all r&d into alternative energy. I'd say the forward thinking in this way is evident by the introduction of a couple production electric cars and bike, then almost halted completely, and the boom of intelligent safeguards immediately following. |

Also, electric cars have been around almost a century, which is old tech. I think there is a smarter technology we haven't discovered yet. People in the 1930's would have never believed in the technology of today, just like we can't imagine technology of the future. People can charge things wirelessly now, which is pretty amazing to think about. All the engines and their modes of energy currently will be the equivalent of the steam engine in the next 20 years if the money is put into the right r&d. It's going to be exciting!

The law of energy conservation says, in summary, that some energy will always be lost in energy transfer. This is almost always due to heat. So, yes, energy in, energy out. Some of the out is heat that is lost in the atmosphere.
My my wife has a BMW i3. The all electric one with no "range extender" gasoline motor. The two year lease is up in April.
excellent car.
zero maintenance.
fast as hell to 93 mph.
About 100 miles per charge if the eco mode is used and you don't exceed 56mph.
70 miles with normal driving.
We've spent $280 in electricity for 11,000 miles of service.
This equals 40 miles per dollar. (39.285) Even at $2.00 per gallon of gasoline, that's 80 mpg. 120 mpg if gas were $3.00 per gallon.
It's a 2015 model. The 2017 model already gets about 20 miles more range. I think range performance will continue to increase each year.
Charging is still an issue unless you can find the 30-minute quick chargers. There aren't many.
in my opinion, the real issues are the stupid CARB regulations.
Example. The range extending (REx) i3 has a 650cc BMW twin cylinder engine buried in the rear lower compartment. Its sole purpose is to charge the battery. If you keep gas in it, it will go unlimited miles because the REx charge out paces the kw consumption. Even with the battery at 6% and using the REx exclusively, the mileage is over 40mpg mpg.
The fuel tank is an unfortunate 2.1 gallons. Why? Because CARB prohibits a car from being called an EV if the the fossil fuel range exceeds that of the battery.
The problem is that these EV cars came with federal tax rebates (and some states too.). These rebates only applied to EV cars, not LEV cars (low emission vehicle.)
So, an otherwise very efficient vehicle with great performance and excellent reliability is handicapped by stupid rules that don't promote technical advancement.
This reminds me of the early sixties Ford OHC engines that literally lapped other vehicles on stock car tracks (That's the old name for NASCAR for you younger readers.)
Solution? Ban it, let the Japanese run away with the tech and leap 30 years ahead of US auto technology........
And Oula. We have the FZ-10!

Im with you on the batteries being the limiting factor, but most auto makers are using metal nickel halide batteries, Tesla is using Lithium Ion. Toyota has just now started using Lithium batteries to. With the lithium batteries the range is into the 300 miles, and they are able to do a quick charge in 45 minutes.
Toyota is pushing hard with it's fuel cell tech, but I personally don't think it'll go mainstream. They installed it in a camry size car, when i asked a FTS about the weight he told me it was around 5,000lbs. Thats just insane for a tiny car.

And, how much of a premium was the lease payment on your wifes car compared to the gas model? Add that on to the cost of running it 11,000 miles and recalculate. Not being a wise guy, but that is a valid piece of the equation. |

Not being a wise guy, but that is a valid piece of the equation. There is no gas model of the i3. Only the EV (all electric) or the LEV (same electric car with range extender.). It is a ground-up new design electric car; not a car modified to electric power. The REx model costs $8,000 more than the full electric model. More importantly, we got a $7500 federal tax rebate and a $5000 state tax rebate. That only applied to EV cars. Not tax credit, a tax rebate. So the purchase/lease price was very similar to a similarly equipped 328 sedan. |

But. My point wasn't to promote this BMW, or even the ownership of electric cars, only to share some real-world facts. I think they have their place, but advancement in battery and charging technology is necessary before they can replace current technologies.
The major downsides of non-Tesla electric cars is the range, charge time, and location of charging stations. I live in Savannah. The nearest cities are Jacksonville 120 miles south, and Charleston 100 miles north. We can't reach either on a single charge, and the charging stations are sparsely located. Even then, it's a four hour wait at a normal charging station.
My wife uses it around town, and going to work and back. She rarely needs more than 70 miles per day. It's charged in our garage at night. So, it's a local commuter car.
Also, without the tax rebates, we wouldn't have made this experiment. Overall though, it's an impressive tecnology within it's limits.
BMW apparently believes in the tech. They have a purpose-built factory just for the i3.

Okay. No non- electric comparable. We see these premiums in other places like hybrids. Didn't you have leases available on non- electric BMWs for similar model packages?
Totally agree with what you say. Bottom line is electrics are getting there, but still have a ways to go.

Totally agree with what you say. Bottom line is electrics are getting there, but still have a ways to go. Yes. The premium exists, but was offset entirely by the tax rebates. That's the only reason we considered this car. The 328 with similar features had the same net price once rebates were applied. So we made money on the fuel savings. If a non-premium car company were to make a similar model, it would be a winner. As I is, thenNissan Leaf is too entry level. |

Thank you so much for your contributions!!! ~Brian Thanks. I have no reason for rudeness. I don't think Tigershark does either. Just a discussion between reasonable adults. We did however get off track from the original solenoid fired valves. That's just badass. With a bit more R&D, they'll find they can make the valve openings any shape they want. This will in turn allow extremely oversquare stroke/diameter dimensions, that will then lead to super extreme rpm. Imagine your average family sedan screaming down the highway at F1+ RPM. |
