Definitions

  • the present disclosure relates to a system for measuring output of a large-sized low-speed two-stroke engine and a method for measuring output of a large-sized low-speed two-stroke engine, more particularly, to a system and method for measuring output of a large-sized low-speed two-stroke engine, the system and method being able to more accurately measure output of an engine by removing a torsion error and an explosion angle error of a crankshaft.
  • a ship engine monitoring device is rising as necessary equipment for maintenance of ship engines.
  • ship engine monitoring devices necessarily require a technology that minimizes measurement errors to perform precise and accurate measurement on engines, and to this end, various measuring technologies have been developed.
  • An indicator for measuring the output of ship engines is representative of the measurement technology of ship engine monitoring devices and is classified into a mechanical type and an electronic type.
  • a mechanical indicator has been generally used for ships in the related art, and is mounted on a test cock of an engine and performs measurement by drawing the pressure of a combustion chamber on paper and then calculating the area using a measurer called a planimeter.
  • the mechanical indicator has a problem that there is an error of around about 10% between the actual state of an engine and the measurement result due to the proficiency of the person who performs measurement and an error of the measurer.
  • An electronic indicator measures the output of a ship engine, unlikely the mechanical indicator, by drawing a volume diagram through sampling on pressure for one cycle of the engine using digital equipment and by automatically calculating the area.
  • the electronic indicator samples pressure for one cycle of an engine through a time-based method or an angle-based method.
  • Sampling based on the time-based method is a method of collecting pressure values in accordance with a set time unit for one cycle of an engine and sampling based on the angle-based method means a method of collecting pressure values in accordance with a set angle unit for one cycle of an engine.
  • sampling based on the time-based method has a problem of causing a large top dead center (TDC) error because it ignores an instantaneous speed change of an engine.
  • TDC top dead center
  • sampling based on an angle-based method that collects pressure values using an angle sensor (encoder) that is installed at an end of a crankshaft is usually applied in the related art.
  • ship engine monitoring devices of the related art measure the output of an engine using an electronic pressure measurement technology employing the sampling technology based on the angle-based method for accurate and precise measurement.
  • a TDC error of 1 degree causes an about 10% error in the output of the engine, so it is very important to measure a TDC when measuring the output of an engine and previous researches recommend a TDC error within at least 0.1 degrees.
  • ship engine monitoring devices of the related art do not consider errors in torsion of a crankshaft and in explosion angle of cylinders when measuring the output of a large-sized low-speed two-stroke engine. That is, ship engine monitoring devices of the related art match a Z-pulse (a signal generating a pulse one time for one revolution) of an angle sensor mounted at the end of a crankshaft opposite to a flywheel with the actual TDC of a first cylinder, so accurate measurement is possible for the first cylinder.
  • a torsion error and an explosion angle error of the crankshaft are not considered for the other cylinders, so the error between the actual output of the engine and the measured output exceeds a reference error range.
  • the flywheel of an engine is disposed opposite the first cylinder where an angle sensor is set, ship engine monitoring devices of the related art determine that rotation occurs relatively early due to torsion by rotation, so they recognize the position of a TDC to be placed before the actual position. Accordingly, the calculated output value is larger than the actual output value of the engine.
  • WO 2004 048762 A1 discloses the determination of the actual top dead center (TDC) of a predetermined reference cylinder and corrected using a known loss angle.
  • DE 10 201 1 083471 A1 discloses a deviation of the expected TDC based on the measured TDC of the reference cylinder that is caused by torsion of the crankshaft. This torsion is detected using at least two cylinder pressure sensors in the first and last cylinders.
  • US 2016 146132 A1 discloses angle deviation of cylinders caused by torsion of the crankshaft and that the cylinder pressure detection becomes more accurate if the exact position of the piston in the respective cylinder is known.
