DS-3000 Series Combustion Analysis System

A comprehensive combustion analysis system that will help research and development to increase fuel efficiency in smaller engines.

With the ongoing research and development for improving combustion technologies (HCCI, EGR, etc.), new power sources (HEV and PHEV) and new fuels (biodiesel and natural gas), demand for the development of more fuel-efficient and smaller engines is rising. The DS-3000 series combustion analysis system meets this growing demand with powerful hardware. This instrument is modular and so can be customised to suit your exact requirements. Please get in touch with us to discuss your needs and for purchasing information.

Features

  •  Supports multiple types of fuels (liquid fuel, gas fuel)
  •  Trend monitor and calculation of maximum cylinder pressure and IMEP in real time
  •  Trend display in real-time
  •  Supports start / stop combustion testing
  •  Enable measurement without an encoder
