s possible. This retains valuable energy with- n the exhaust gas so that it can be utilized vhere it is needed, in the turbocharger. As a special feature, the split-circuit cooling system for engine and intake-air cooling com- plements the turbocharger system and acts as an "intelligent" cooling system, keeping the engine coolant, oil and intake air at the opti- mum temperature under all operating condi- tions. When idling or at partial throttle, for example, the temperature of the intake air is raised to ensure smooth and complete combus- tion without white smoke. At full throttle, max- imum cooling of intake air maximizes engine performance. All of this is achieved with a cool- ing system that is fully integrated within the engine and optimized for minimum space requirements. The Series 4000 The motivating force behind the development of the Series 4000 engine was the need for a compact, high-performance diesel engine in the output range above 700 kW, according to MTU. Generously proportioned access ports in the crankcase reportedly make it possible for all servicing operations to be carried out without having to remove the engine, even in cramped conditions. On the "front" end of the engine, for example, there is an integral service block posi- tioned for best accessibility to suit the particu- lar application, significantly simplifying all standard service operations. The electronic engine management system provides advanced information of the service work required. The pistons (steel crown, aluminum skirt) are fitted with wear-resistant, chrome-ceramic coated piston rings which, in combination with the plateau-honed cylinder liners, are designed for low oil consumption and long service life. The cylinder heads, with integral coolant pas- sages, are designed for maximum combustion pressures of up to 200 bar and have a specially stiffened base. The manufacturer said that exceptionally good fuel consumption is achieved using a com- pletely new common-rail injection system. Whereas the injection pressure in conventional systems is virtually incapable of change over the engine operating range, both injection pres- sure and injection timing can be freely pro- grammed with the common-rail system. The high pressure pump and electronically controlled injectors are fully integrated in the electronic control concept, providing low con- The crankcases of MTU's new Series 2000 and 4000 were opti- mized for casting and production in conjunction with the suppli- ers. MMC CL0SE&MMPUNG SAMPLING MADE SIMPLE! MMC's new Closed Sampling Tape has its own built-in sampling port. Take a look. The sampling port is located at the base of the barrel. Just put the tape in place on any one of a wide range of existing MMC deck valves, twist the collar and you're ready to go. (There's even a handy adaptor to make it fit non-MMC valves.) Its closed construction keeps emissions from escaping into the atmosphere so you're in compliance with all applicable vapor-control regulations. A return hose assembly even directs vapors displaced from the sample bottle back into the system. The sample bottle is then quickly and neatly removed, and capped for testing and/or laboratory analysis. One final point: It's all made in the USA by MMC, a name you've learned to trust for over 50 years. MMC (Europe) Ltd.
