Cat Common Rail - The Benefits With Cat Common Rail, the injection pres- sure is independent from load and speed. Utilizing injection maps the injection characteristics are optimized for every engine operating point. For areas that are especially emissions- sensitive, soot emissions at low engine load remain well below the visibility limit. Furthermore, during normal load operation N0X emissions can be reduced without sacrificing fuel consumption. Depending on application, as well as operating conditions, engines equipped with Cat Common Rail fuel system technology can positively impact the transient response. In general, the Cat Common Rail fuel system enables vessel operation with- out visible soot throughout the whole operating range. In addition to that, the fuel system is capable of multiple injection. Multiple injection allows optimal combustion and low emissions at all loads. Characteristic of Cat Common Rail is the approach of using the fuel (whether it's heavy fuel oil, marine diesel oil or diesel oil) as the control fluid for the injector, thus avoiding the added complexity of a separate control fluid system. During the development, the retrofit aspect of the complete system has been emphasized. As a result, the Cat Common Rail fuel system can be retrofitted to existing M32C engines. This means increased customer value to reach future environmental regulations.

CCR_2011_Layout 1 16.01.12 16:51 Seite 2 Cat Common Rail – Fuel System Cat Common Rail – Technology From its introduction the MaK long-stroke generation of main diesel engines has been recognized for good performance and reasonable fuel consumption, alongside outstanding reliability and long component life. MaK engines are compliant with current emission regulations without the need for additional aftertreatment. To fulfil the upcoming emission legislations the development of new combustion process supporting technologies is necessary. Caterpillar has chosen “inside the engine” measures as the...
