ENGINE TECHNOLOGY
The Cat CEM is an exhaust aftertreatment package consisting of a Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR)catalyst, using a urea water solution (UWS), known as Diesel Exhaust Fluid (DEF), and control systems. The CEM reduces both particulate and NOx emission using passive and active regeneration, dosing, burner and dosing/burner combinations during normal engine operation. All components are isolation mounted on a rigid supporting cradle for long service life in the most severe applications.
The Cat NOx Reduction System (NRS) captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.
Mechanically actuated Electronic Unit Injection (MEUI-C) multiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, generating fewer emissions and optimizing fuel combustion. This translates into more work output for your fuel cost.
Regeneration is the removal of soot from the Diesel Particulate Filter (DPF). The Aftertreatment Regeneration Device (ARD) utilizes the Cat Regeneration System (CRS) to efficiently and automatically regenerate the DPF. The DPF traps both particulates and ash; the ash is removed at regular service intervals.
When set to automatic, regeneration will occur without any interaction from the operator. The three modes of regeneration shown below allow the articulated truck to adapt to specific site conditions in the most efficient manner. Automatic: “On-the-go” regeneration is initiated when the engine control module determines conditions are acceptable. The articulated truck is not required to stop working. Automatic: Low idle regeneration is initiated when the machine is in a reduced operating mode for a predetermined period of time, and a number of conditions are met. The system is designed so that the operator can interrupt regeneration at any time. Manual: A manual regeneration is initiated by pressing the regeneration switch for five seconds. The machine must be brought to a non-operating mode in order to perform a manual regeneration.
In the case where we want to be able to continually monitor the route Caterpillar 730C, we need to apply the solution Car Track. This is necessary due to the fact that, unfortunately, this factory-mounted machine does not have any GPS transmitter. Car Track however is a completely free solution. Just stock up on phone type smartphone running Google Android or Windows Mobile and install the free app Car Track. When you install a smartphone in the cab of the machine will have the opportunity to watch the route in real time on the web from anywhere with internet access. You will be also view previous routes and share saved others. This solution will facilitate the construction company if we have a machines.
