Komatsu Ltd is set to produce a new range of engines that are compliant with the latest emission regulations in Japan, North America and Europe.
The Japanese construction manufacturer will begin commercial production of its latest models this month.
The new regulations, which come into force this year, were originally announced in 2004, and demand significant reductions in nitrogen oxide (NOx) and particulate matter (PM) emissions. Both sets of emissions must be reduced to one tenth of the levels stipulated by the previous regulations.
In response, Komatsu has developed and adopted a high-pressure common rail fuel injection (HPCR) system, a high-efficiency exhaust gas recirculation (EGR) system, a variable geometry turbocharger (VGT) system, and a diesel particulate filter (DPF). In addition to refining the above technologies, Komatsu’s in-house team has developed a new selective catalytic reduction (SCR) device.
Komatsu collaborated with engine manufacturer Cummins Inc to develop a new line-up of engines with applications ranging from small construction equipment to large mining machinery.
The firm says that it will continue to take advantage of in-house development and manufacturing capabilities for other key components, such as hydraulic devices and control systems, in order to mitigate environmental impact and improve fuel economy.
