Abstract: The
effective thermal efficiency character of internal combustion water
power device is studied through experiment. The device integrated
traditional combustion engine and plunger pump technique, made directly
use of the rectilinear motion of plunger for outputting water power.
The optimal effective thermal efficiency working zone and optimal
effective thermal efficiency curve are defined and compared with
traditional internal combustion engine driving plunger pump. The
effective thermal efficiency in total working conditions of the device
is higher than traditional internal combustion engine driving plunger
pump by 13.63%～74.45%. The working conditions in same effective
efficiency level of the device is Wider than internal combustion engine
driving plunger pump system. The highest effective thermal efficiency in
different throttles of internal combustion water power device is between
19.91% and 28.88%, corresponding rotational speed is about 1400 r/min.
