By integrating a temperature sensor into each heating area, the temperature of each heating area may be monitored and controlled individually. By providing multiple heated surface and multiple heater stages, rapid and complete fuel vaporization is provided. The generated fuel vapor may be used for any number of exhaust after-treatment processes, such as in exhaust fuel injection, diesel particulate filter burnout by igniting the vapor to perform fast warm-up of a nitrogen oxide absorber, or as an oxidation catalyst.Type: ApplicationFiled: April 25, 2008Publication date: October 29, 2009Inventors: Oscar A.

Publication number: 20090239426Abstract: The invention relates to fuel system for gas driven piston engine in a marine vessel, which gas is stored in at least one fuel storage tank in the vessel as liquefied gas. The fuel feeding system comprises a separate fuel feed tank in which the gas is in liquid phase and at elevated pressure. The gas is also in liquid phase in the fuel storage tank, in which, however, prevails only the hydrostatic pressure caused by the liquid gas.Type: ApplicationFiled: June 1, 2007Publication date: September 24, 2009Applicant: WÄRTSILÄ FINLAND OYInventors: Oskar Levander, Tuomas Sipilä
