One of the support pillars that UT serves to customers is the Application Engineering support, by providing equipment owners with knowledge about equipment character and operation methods to achieve optimum production rates and operating costs. Similarly, this reflects the purpose of observing the fuel consumption of PC200-8 operated in Padalarang.

 

Fuel Economy
Komatsu has been developing and manufacturing construction equipment since 1931, and diesel engines since 1935. Supported by such experience, the ecot3 technology was developed, aiming to preserve the environment sustainability (ecology) as well as customer productivity (economy). What makes Komatsu equipment successful is its strong technological capabilities and power that integrates into efficient machinery.

 

PC200-8 excavator which will be launched on January 21st, 2010 is supported by Komatsu SAA6D107E engine technology and PC200-8 hydraulic total electronic control system which is capable to control the fuel supply through High Pressure Common Rail (HPCR) that is electrically controlled and therefore producing optimum results. See the picture below.

 

The HPCR (High Pressure Common Rail) fuel injection system feeds the fuel into high-pressure pump, to be stored it in a pressure vessel called "Common Rail", and then injects the pressurized fuel into cylinders which are controlled by computer (controller).

 

With conventionally used mechanical injection pumps, since the injection pressure is low, it would be difficult to meet the standard requirements of both NOX emission reduction and performance improvement.

 

Since HPCR fuel injection system is not only capable for high-pressure but also providing optimum quantity and multi level injection, it produces better combustion, resulting in reduction of fuel consumption. Hence, output performance is improved and noise is reduced.

 

Field test results shows that the ratio of production to fuel in PC200-8 with E work mode is amounted to 5.23 lcm/ liter, which is 16% higher from P work mode of 4.5 lcm/ liter. This is due to the type of work in PT Nyalindung which is relatively simple so that UT Engineering team recommends to set the working mode at Economy Mode.

 

Another advantage of PC200-8 is the usage of KOMTRAX for remote monitoring system of fuel consumption and fuel consumption test monitored direct from PC200-8 cabin panel. Fuel consumption is the largest cost, averaging nearly to 60% of heavy equipment operational costs. That is why fuel consumption monitoring is essential.

The fuel consumption monitoring system through KOMTRAX will protect the equipment from cases of fuel stealing. Customers can check fuel condition contained in the fuel tanks as well as fuel consumption within certain period of time. This is shown in the January 2010 fuel consumption report of PC200-8 which are working in Padalarang grit mining, Bandung (see picture above).

Aside from being monitored through KOMTRAX, fuel consumption can also be checked directly on PC200-8 cabin monitor. The facility allows operator to verify fuel consumption in a short time units (litres/hour). This feature can be accessed through PC200-8 fuel consumption menu. For verification, operators simply need to press the start and stop button, then the results will be displayed right away, as shown in this picture.
