Answer 1

ps is "pferdestärke".

"German word for horsepower, meaning the metric horsepower. The symbol ps is used for horsepower in both the Japanese and German automotive industies."
http://www.unc.edu/~rowlett/units/dictP.html
metric horsepower
a unit of power, defined to be the power required to raise a mass of 75 kilograms at a velocity of 1 meter per second. This is approximately 735.499 watts or 0.986 32 horsepower. The unit is known in French as cheval vapeur, in Spanish as caballo de vapor, and in German as Pferdestärke.

So 18ps =17.75 Hp

PS

This unit (German: Pferdestärke = horse strength) is no longer a lawful unit, but is still commonly used in Europe, South America and Japan, especially by the automotive and motorcycle industry. It was adopted throughout continental Europe with designations equivalent to the English "horse power", but mathematically different from the British unit. It is defined by the Physikalisch-Technische Bundesanstalt (PTB)[1] in Braunschweig as exactly:

1 PS = 75 kp·m/s = 0.73549875 kW = 0.9863201652997627 hp (SAE)

The PS was adopted by the Deutsches Institut für Normung (DIN) and then by the automotive industry throughout most of Europe, and is always measured at the wheels, as opposed to most factory horsepower figures, which are rated at the crank (which is measured right off the motor, not accounting to any drivetrain loss, which is especially considerable in an All wheel Drive configuration).

In the 19th century, the French did not use this German unit, but had their own, the Poncelet. In 1992, the PS was rendered obsolete by EEC directives, when it was replaced by the kilowatt as the official power measuring unit, but it continued to be used for commercial and advertising purposes, as customers were not familiar with the use of kilowatts for combustion engines.

Answer 3

Engine HP (also called brake-horsepower) is measured with a dynamometer. Essentially the operator puts a higher and higher load (through friction braking) on the engine, until the engine stalls. The operator is allowed to adjust RPM or fuel to try to keep the engine turning. The more friction braking the engine takes, the higher the horsepower. In a way it's like using successively heavier drags in tractor pulls. See the source for an in-depth article.

Answer 4

PS is the German measurement of Horesepower. In German the PS stands for Pfeldenstrasse

Answer 5

I've never seen it before. If you can present a description of the engine (Otto? Diesel? something else?), the size and number of cylinders, and typical operating speed, a good guesstimate could be made.

Answer 6

sounds like Pounds per square inch if the i is missing unless is metric which i m not familar with that one either.what kind of motor? gas ,electric ,model engine,
