ICE_engines

Someone stated in a post earlier that ice engines have not advanced since the ply duster was sold on the market in 1970. A Japanese company has come out with a 1.5 liter 3 cylinder turbo gas engine that can vary its compression ratio between 8 to 1 and 14 to 1 depending on driving conditions. This engine is rated @ 201 horsepower and mileage is rated at combined 33 mpg. You can order this engine in certain models of Rogue suv's made by this company for 2023 model year. It has been road tested and is has been released to the market and is being manufactured now. I don't know how durable it will be. Seems like engineers working for auto companies realize ice engines are going to be in consumer demand for quite some time with these new technologies coming out for ' old ' engines. Do you think there have been any advancements in ice engine design since 1970 ?

There have been plenty of advancements since 70. Engines were worn out at 100,000 then. They don't use a drop of oil at that stage now and it isn't because of the oil. It's all due to the electronics and fuel injection both of which are still being improved.

They are going to have to beat 33 to impress me. The wife's ten year old Fusion gets 27 in town and 40 on the interstate.

Fuel management has improved immensely in diesel trucks too.i have a friend that used to change his oil at my shop,and I would get his oil to burn.He ran 150,000+ miles a year,and would change his oil at 10,000.He had dual Luber Finers on the outside,and held closer to 15 gallons than the normal 11.I got over 200 gallons of oil from him every year.His new truck only holds 7 gallons,and the change interval called for is 50,000.My oil supply was going to be cut to 21 gallons a year.He's not waiting to get to 50,but he's not changing at 10 anymore either.I have no idea what kind of powerplant he has in the new truck,but the used oil comes out golden.

Ah not All were wore out . I put a 168 and change on my 68 383 Road runner and i can say she got run hard and was NOT and oil burner 71 Duster 340 another one that got the bag run off it and a 178k and change and still would put the fear of god into a sane person . , Yes working in dealerships we saw OIL burners BUT not due to being wore out , valve guides oil being sucked past intake gskt. , but when you opened them up you found vary little ridge and still saw cross hatch in the walls . Take a 385 block ford engine when ya treat one of them puppys well they can run a couple hundred thousand miles as my 88 F 350 did with 287k on it , That one got the wheels run off it with about 50% of the time pulling a 28 foot gooseneck that 90% o the time was overloaded. . Yea in the mid to late sixtys F E block fords had and issue with drinking oil , many were pulled down and reringed but that was NOT the issue here it was intake gskt. sucking oil as there was always oil running past it and seeping in . Then there was and unannounced recall when ya got in and F E not to pull the engine down and rering but to replace intake gskt. Just a couple drops of oil per mile turns into a Qt every 400-600 miles as so we were told . Factory engine tolerance varied . piston rings were just plain old cast iron and compression ratio's were MUCH higher qand engines ran at higher RPM driving down the road . Say you had a car with 14 inch tires with a 28-9 inch rolling height and a 3.23-25 gear in say third in a slush box or forth in a gear box at 45 Mph you were turning 2000 RPM at 70 MPH you were now turning around 32-3400 RPM and getting with the program up in the triple digits your running 55-56000 rpm , Now today on the War Dept's new jeep Cherokee at 75 MPH it is turning just around 1850 and sill had a gear or two to go UP but let it drop five it drops one and now is running at 2000. as this is where it like to be between 1850 and 2000. But back in the OLD days you would be between 35 and 45 MPH . A OLD gas tractor from back in the OLD days would eat around 2 Qt's of oil a day working hard. The OLD Detroit's in semis would between leaking and burn a Gallon a day . Between oil changes and back then we changed oil about every two weeks you could plan on one barrel a month . darn good thing it was Cheap at under a buck a gallon and sometimes as low as 45 cents a gallon when ya bought a pallet of four drums and you picked it up . Nobody really cared . Just pull the dip stick and OH it NEEDS and you dumped . with the semi and the old 318 when you fueled at night while the tank was filling you just automatically went and got a gallon and DUMPED .a half day on Saturday took a half gallon . They burnt oil and leaked oil even after a rebuild , but it might take a month to start leaking after and out of Chassis . But the inframes ya may get the heads and valve covers not to leak for a month or two but they still drank oil. It did not matter who did the rebuild if it was your vary first or ya did three a week .

You must have had some real knuckle-draggers on that crew if they couldnt build a dry Detroit out-of-frame.

What is a ICE engine? Had diesel gasoline and LP. Sure never thought about runniung one on ice.

ICE stands for Internal Combustion Engine

Thank you. Really aggravets me when posters are to lazy to really say in topic what they are talking about

Fuel injection and variable valve timing are 2 big advances that I can think of. And using synthetic oil has made a big difference too.

It is actually an IC engine. An ICE engine would be an internal combustion engine engine. No real advancements in the underlying technology of IC engines since the time of Benz and Ford around 1900. It is simply a matter of containing a rapid combustion (through valves and a piston) to convert expansion into a rotation. Everything else is a refinement of the existing concept.

The same could be said of electric vehicles. Note that they were around even before internal combustion engines.

Very true. I had to look that up. In 1832 Robert Anderson invented a very crude EV. 1870's they became more practical. @ 1890 the first sucessful EV was by William Morrison. First internal combustion engine was by a Belgian inventor in 1863 fueled by a turpentine deriative. This info was from the all knowing Google!

An I C gas engine that continuously adjusts its compression ratio between 8 and 14 to 1 is pretty advanced engineering. Maybe even revolutionary. I know of no other auto , truck or tractor company that has engineered an engine that does that. That engine even thou from a foreign owned company (nissan) is made right here in the U S in Tennessee. There are other advancements that tractor vet hit upon such as piston ring metals & close tolerances in machining and cylinder wall coatings that are engineering advancements also.

Mrs Ford drove an electric car if i recall. I believe Mrs Oliver (keeping it Antique tractor) did as well.

I work for a very large automotive supplier. We have made a lot of different parts that are very central to the internal combustion engine and have for over 100 years.

listening to management talk they are all in on Electric. we have the capability but are a bit behind other companies. a bit concerning. my division will still be around as we make other components like cooling and HVAC fans and power windows and seat ect ect that you need regardless of the power origin of the car.

As i've stated in other posts. I think its all (carbon neutral/green) a BIG scam but one that seems to have stuck for now. when it doesn't work and people start going hungry or freeze it will change and/or fade away but in the mean time watch out. at this point in history electric cars are NOT green!!!!

Continental had VCR engines in the seventies, but never heard any more about them until now. They build engines for military and aircraft and dont offer anything to the general public these days.

Do you think there have been any advancements in ice engine design since 1970 ?

I remember my old cars could pass anything on the road except for a gas station.

Any advances? Heck yes. Just look at the improved mpg and how long the engines last.

What engine did the Belgian invent? Internal combustion covers a few different things... turbine, rocket, ramjet.... according to The Story of Power, published by GM in 1955, the four cycle engine was invented by Nicholas Otto.

Need convincing? Drive a 2.0 four cylinder from 1975 and then one from 2022.

So you get 201 HP but at what engine speed are they getting this HP. I'm betting it is much higher RPM's than the older slower engines were at to get it. Like my semi. It gets to peak torque at 1200 RPM and Peak Hp at 1600 RPM Newer engines may run a bit slower but they shift them and run them only about 300,000-500,000 miles then trade them. The old V-8's ran wide open at about 4400 and ran engine speed on road at around 2000 these new engines are gutless wonders unless they wind up to about 3000 just to gain speed in less than 10 miles to attain road speed. Just under powered puddle jumpers.

Around 1860 Belgian inventor Etienne Lenoir created the first commercially successful internal combustion engine, a 2 stroke engine that ran at 100rpm. 1876 Nicolaus Otto created the first modern 4 stroke I/C engine. But I also found that in 1823 Samuel Brown patented the first I/C engine, a gas vacuum engine. All of this info was aquired by doing a Google search on the subject

Saab built a variable combustion ratio engine in the late 1990 s and tested it, but never offered it to the public.
On the subject of “ICE engines”, another example seen a lot on this forum is “VIN number”. VIN is an abbreviation for Vehicle Identification Number, so there’s no need for the extra “number”
