Single piston engines

Yeah, it is.

Another term for it would be peak horsepower.

But still, people can develop 1 HP. Period.

In determination of power, there is no requirement that the power be maintained for any period of time.

If the only cars sold were the midget cars, you can bet they price will need to more than doubled ;)

What's you point? Even if only two trucks out sold the Camry, how would that effect the jist of what was posted, that being that buyers do not choose to buy the midget or small cars that are currently available?

Crosly never made the engine, they like K&F used Continental engines.

The Japanese manage to do it quite well with "kei cars". They are limited to about 600cc engines, small, fuel sipping, agile little cars, trucks, and vans. And most sell for under 750,000 yen (under $7500 roughly)

Point 1: The world is changing. Things are not the same in the car industry as they were when you worked for Ford. Just because GM and Ford were #1 and #2 in car sales for many years, that does not mean that they will ever be again.

Point 2: The facts and numbers are readily avialable. It took me 1 minute to double check this. And, that Camry and Accord outsold the Ram last year was posted here a few times. To maintain your argument, you need to check your facts.

I'm not going to follow you in one of your circles. The fact is as I pointed out, the best selling vehicles in the US are trucks, not cars and the best selling cars are not small cars. Americans still buy millions more domestics than imports. both cars and trucks. Toyota is millions of vehicles away from being number one in the US. You however are free to believe whatever you chose.

The fact is that you changed my post without indicating that fact. That is intellectual dishonesty.

And, I think that getting your facts wrong, especially when they are so easy to check, makes you look like an idiot.

Forget 1-cyl. They have balance/vibration problems making them unsuitable for autos. I doubt there are even any serious mot'cycles with 1-cyl anymore (there were years ago).

The closest I've seen to what you describe was the NSU Prinz:

'Twere a -very- tiny german car with a 2-cyl. 600cc air-cooled 'cycle engine (RWD). I drove one in '64: it rattled a bit but was perfectly functional around town.

I 'spect the reason such a car is now totally impractical is because of the grand proliferation of "The Great American Pigmobile": no visibility from such a tiny car, and they'd likely kill ya. It has become a "cultural" thing.

You free to believe whatever you choose, I could not care less. What you choose to believe however will not change the fact that the best selling vehicles in the US are trucks, not cars and the best selling cars are not small cars.

Gee, you told us last time. You're like a broken record. And, old enough to know what that means.

It seems you seldom understand what is said the first time, because you are too busy picking through everybody's posts for something with which you can disagree, rather than digesting what was posted, thus requiring others to be repeat things for you LOL

I am not disagreeing with an opinion. You get the facts wrong, and I am pointing this out.

You've got to take more effective mind-reading classes, man. I understand perfectly well what you are saying. What you offer is rarely worth the effort of digesting.

I can tell you used to be a manager. You get the facts wrong, but somehow, it is someone else's fault.

Don't have a cow man! (I said that last time, but you seem to have deleted this - another intellectually dishonest move. I mean, gee, don't be so stupid as to remove stuff from a post when I know darn well what I said, and I can easily verify it.)

You're just so funny Mike.

The very definition of horsepower is ALL ABOUT TIME...:

"33,000 ft·lbs per MINUTE" is one horsepower.

A boiler horsepower is used for boilers in power plants. It is equal to

33,475 Btu/h (9.8095 kW), which is the energy rate needed to evaporate 34.5 lb (15.65 kg) of water at 212 °F (100 °C) IN ONE HOUR.

There is no measurement of horsepower w/o the time factored in.

Right, and if you do 1/60th of the work (550 ft-lbs) in one second, then you still are developing 1 HP. The ft-lbs is the amount of energy needed to life

550 lbs 1 ft or 1 lb 550 ft.

Power is work divided by time. The time is not specified. If a 150-lb person climbs 7 1/3 feet of stairs in 2 seconds, during the 2 seconds he has an average power output of 1 HP (assuming your 33,000 ft-lbs per minute is accurate). Now assume that the same person climbs 220 ft (a 22 story building) in 1 minute. That's a lot. This like 1 story every 3 seconds. He would be doing 33,000 lb ft work working (lifting a 150 lb object 220 ft) in one minute.

1100 lb-ft / 2 sec = 33,000 lb-ft / 60 sec. You don't need to maintain the same power output for a full minute for it to be the same power output.

Look at what you wrote. 33,475 Btu/h = 9.8 kW. A watt is also the unit for electrical power. A 100 W lamp uses 100 W of electricity whether it is on for 1 second or 5 years. There is no requirement that a light bulb remain on for particular period of time to achieve a particular power rating. That is because the amount of power developed is not related to the duration of power generation.

Correct. The power is the work divided by time it took the work. And I (227.5 lb) climb a stairwell that is 145 ft high in 1 minute, I will do

33,000 lb ft of work, which is one HP sustained for 1 minute. If I climb a stairwell that is 2.42 ft high in 1 sec, I will be doing 1/60th of the work (550 ft lb) in one second. The rate (550 ft lb per second) is equal to 33,000 ft lb per minute (550 ft lb per s times 60 s per minute = 33,000 ft lb per minute).

So, I can reasonably sustain 1 HP of work for a few seconds (maybe climb a 7 ft staircase in 3 seconds), but, until I get in better shape, I doubt I can sustain 1 HP for a minute. If I try, I might be riding in the back of a 300 HP vehicle (an ambulance).

You're embarrassing yourself in front of the world on an archived forum, that people will be able to read, for some years to come...

I'd stop digging such a big hole if I were you.

Does my car's engine not put out a true 150 hp on a dynamometer if I only run it for 10 seconds? One second? Or even a handful of crankshaft revolutions? How long do you think you need to produce a particular horsepower reading before it becomes 'real' enough for you?

If you think through your answers you might see where you've screwed up. Or else you're trolling and I should take this hook out of my mouth.

Well, how about that 1 hp human powered bike. That's all I'm talking about here, 1 hp just cannot be usefully sustained by a human for practical transportation. 2-3 minutes just won't get you to work on a bike. That's all.

Your car's engine can have instantaneous HP way beyond 150. It just won't last long.
