Diesel engine testing

Australia’s market-leading experts in diesel engine testing.

CMTS is NATA-accredited and licensed by the NSW Resources Regulator to carry out raw diesel exhaust gas and particulate analysis.

Overview and background

There is sufficient evidence to link exposure to diesel exhaust to an increased risk of cancer.

In an underground mining environment, workers may be potentially exposed to diesel exhaust fumes where diesel powered equipment operates. Mining regulators and mine operators actively seek practical measures to reduce human exposure to diesel particulate matter via engine testing.

Targeted engine maintenance can drastically reduce diesel engine emissions, but workshop employees must have the tools to reliably identify high emitters and to validate the effectiveness of emissions-related maintenance.

Diesel analysis

The analysis and reporting is undertaken in strict accordance with NSW regulations on the monitoring of diesel engine pollutants. Our fleet of fully equipped mobile laboratories enable the work to be carried out onsite, providing timely and accurate analysis for the following components:

  • carbon monoxide (CO)
  • carbon dioxide (CO2)
  • nitrogen dioxide (NO2)
  • nitric oxide (NO)
  • diesel particulate matter (DPM)

The key features of the diesel engine testing services include:

  • NATA accredited, ISO/IEC 17025
  • DTI NSW licensed for diesel exhaust analysis
  • ISO 9001 Quality System
  • NATA endorsed reports issued
  • fully equipped mobile laboratories
  • both surface and underground testing of engines
  • accurate and timely analysis resulting in minimum downtime for the machine database for each engine maintained
  • historical graphical data for engine emissions provided to assist in maintenance scheduling

Initially established for NSW coal industry

Widely utilised across a range of operations

This service is now widely utilised across a range of operations including the Queensland coal industry and in metalliferous mines operating diesel equipment as well as in general industry and road tunnel projects. We have also been actively involved in research programs for the testing of new generation engines, dynamometer engine programs and particulate filtering technologies.
