mechanical engines for underground mining: the N45 MSS X and the N67 MNT X. The engines can be config- ured to meet mining applications including man trips, roof bolters, per- sonnel carriers and service centers. The N45 MSS X is an inline, four- cylinder diesel rated 99 hp, while the N67 MNT X is an inline, six-cylinder configuration rated 175 hp. Enhanced by low ventilation rates, (4000 and 6500 CFM, respectively) these mechanical engines are designed for day-to-day underground operations. For marine applications, FPT NAhas introduced the N67 560 diesel. Specifically for marine use, the N67 560, model N67 ENT M56, is a six- cylinder, four-valves-per-cylinder, inline engine, with a power range of 450 to 560 hp at 3000 rpm, depending on applications. With a displacement of 6. 7 L, the N67 560 marine diesel en- gine is seen as especially applicable for high-performance pleasure crafts. An increased bore and stroke of 104 mm x 132 mm allows for greater power. FPT said the N67 560 engine has total fuel system control due to its high-pressure common rail injection system, and meets current EPA emis- sions regulations. The engine has a dry weight (without marine gear) of 1430 lb. The N67 560 is turbocharged with an air-to-water aftercooler. In general, FPT NA said the N series engines provide access to every part of the engine, thus reduc- ing maintenance time. Plus, with 40% fewer components, the engines fea- ture low lubrication oil consumption. The N series also has a noise level below 91 dB(A), the company said.
Emissions Technology
The design of FPT’s industrial en- gine range features multivalve sys- tems, fixed or variable geometry tur- bochargers, mechanical injection sys- tems, high-pressure common rail sys- tems or electronic control fuel injec- tors, as well as internal recirculation of oil vapor to prevent air emissions. FPT NA said the current range of Tier 3 engines will evolve toward Tier 4 interim with the introduction of new technologies to reduce emissions. Solutions will vary by engine family. More specifically, for the F family, FPT proposes external exhaust gas recir- culation coupled with a diesel particu- late filter. For the C and N engine fam- ilies, FPT will adopt an SCR system. FPT will also apply technologies such as common rail upgrades, high- pressure direct injection systems and a double turbocharger system to its own engine systems.
