Does anyone care to elaborate on the little horsepower vs big horsepower debate?eg;truck HP vs car HP.Are we clear on the difference between force and power?Should we go to a better system for expressing power output?KWs for example?it does get a little confusing(by the way thanks Carolyn)-Kevin

Sorry kmccune you still have the definitions muddled. If you push on a wall and it doesn’t move that’s force. If you push on a wall and it does move that’s work. Force times distance. How fast the wall moves is power. Force times distance/ time. Switching from HP to KW won’t help. Underneath the pri…

It seems to me that the manufacturers are marketing horsepower numbers that are only momentarily produced. The Yanmar and the 300 horsepower Cummins engines are built to deliver their rated power continuously until they are worn out and that might easily be in excess of 10,000 hours. The DKW and the…

Gee thanks guys(I do know that a hydraulic jack can produce a lot of force .but scarcely any power-a starter motor is a torque monster with scarcely any horsepower) probaly its just me,but it seems that some of these descriptions are a bit gray-Kevin

Isn’t horsepower just part of the image. And image sells cars. The ad men make a great deal of color out of gray data. Mostly green.

That's can make for a great deal of fun but for reliable transportation such technology is somewhat of a hindrance. Hey, 100hp/L can be reliable. Look at the S2000 :wink:

The simple answer to your question is definitely not. Starting at the beginning, if you put 1 liter of ideal fuel air mixture at atmospheric pressure in a sealed container and ignite it, the heat released by combustion will raise the temperature and pressure inside the container. Measure the heat r…

Thank you MTraveler,that was really helpful-Does anybody know anything about the the so called adibatic engine? Kevin

Horsepower is a very real concept, but it is one that most people have absolutely no understanding of when they talk about their “300 HP” cars. Think about this scenario. A hypothetical car will go 25 mph at 2000 RPM in a certain gear. In a lower gear, it will go 25 MPH at 4000 RPM. Well, you th…

Hey, 100hp/L can be reliable. Look at the S2000 ;) Honda: When horse power per liter maters more than miles per hour :stuck_out_tongue:

well, let me ask this,does say 100 hp take the same amount of gas basically,regardless of engine configuration?-Kevin
