Pressure Transmitter controls common rail fuel pressure.

Press Release Summary:




With pressure rating of 2,500 bar, Model MBS 6300 controls pressure of fuel injected into cylinder of common rail diesel engines. Thin-film unit is fully welded so there are no seals at pressure element, enabling transmitter to handle over 10 million pressure cycles. With MBS 6300 installed, stable fuel pressure is ensured, resulting in minimized emission rates of soot and NOx at all engine operating points.

Control Common Rail Fuel Pressure with the New Danfoss MBS 6300



As regulations to limit greenhouse gas emissions get tougher, fossil fuel burning industries have to modify the way their fuel burning systems operate. For the operators of industrial diesel engines, engine modifications such as electronically-controlled fuel injection systems are helping cut fuel consumption and reduce soot, nitrogen oxide (NOx) and other harmful exhaust emissions. Always ready to help OEMs and their customers reduce their greenhouse gas emissions, Danfoss has developed a pressure transmitter for common rail diesel engines that will launch in late 2010.

High fuel pressure, low exhaust emissions

Modern industrial diesel engines have to deliver high performance - often in harsh conditions. Highly compressed hot air is used to ignite or combust diesel, but if combustion is inefficient, the quantity of exhaust gases rise. Controlling the pressure of the fuel injected into the cylinder helps reduce these emissions. And that's just what the new Danfoss MBS 6300 pressure transmitter is designed to do.

Coming to market in late 2010, the thin-film MBS 6300 is designed specifically for common rail applications. The new MBS 6300 is designed to handle up to 2,500 bar pressure in the harsh environments of an engine room, the MBS 6300 offers excellent high pressure and vibration stability in a compact design. Fully welded, there are no seals at the pressure element, enabling the MBS 6300 to handle over 10 million pressure cycles. In addition, a low total error band over a wide temperature range and a choice of output options and approvals make it a truly versatile common rail component.

Stable fuel pressure for less soot and NOx

Common rail systems give continuous and load-independent control of injection timing, pressure and volume. And, with the MBS 6300 installed, stable high fuel pressure is ensured, regardless of operating conditions. And it's this pressure stability that results in lower emission rates of soot and NOx at all engine operating points - even without pilot or post-injection.

However, to meet increasingly stringent regulations on emissions, common rail systems are being produced with higher and higher pressure levels, placing more pressure on system components. Depending on engine construction and size, pressures currently range from 1,200 to around 2,500 bar. But Danfoss has factored the increase into the MBS 6300 design, and can support future common rail pressure requirements.
