A fuel reformer suited for mounting on a vehicle is provided. A raw material gas containing methanol and water is vaporized at a vaporization section 30. The vaporized gas flows horizontally to a reforming section 60 with monolithic catalyst 70. The reforming section is divided into two sides, a front side 62 and a rear side 64, with an interconnecting pipe 66 bent at 180 degrees, for connecting the front and rear sides. By making the material gas flow horizontally, even when the reformer is mounted to a vehicle which has a larger space in its horizontal direction than in its vertical direction, especially a small passenger car, the contact time period between gas and catalyst can be extended. By bending the reforming section by 180 degrees, the size of the reformer can be reduced so that the reformer is suited for mounting on a vehicle having limited space. Because the vaporization section 30 and the CO reducing section 80 can be placed adjacent to each other, by using heat generated at the CO reducing section, the heat loss during pre-heating of the methanol and water can be reduced.

Disclosed is an improved analytical method that can be utilized by hydrogen filling stations for directly and accurately calculating the end-of-fill temperature in a hydrogen tank that, in turn, allows for improvements in the fill quantity while tending to reduce refueling time. The calculations involve calculation of a composite heat capacity value, MC, from a set of thermodynamic parameters drawn from both the tank system receiving the gas and the station supplying the gas. These thermodynamic parameters are utilized in a series of simple analytical equations to define a multi-step process by which target fill times, final temperatures and final pressures can be determined. The parameters can be communicated to the station directly from the vehicle or retrieved from a database accessible by the station. Because the method is based on direct measurements of actual thermodynamic conditions and quantified thermodynamic behavior, significantly improved tank filling results can be achieved.

The fuel injector 10 has a ball valve 32 and a valve seat body 41. A fuel jet opening 41c formed in the valve seat body 41 is closed when the ball valve 32 contacts a sealing surface 41b of the valve seat body 41, while being opened when the ball valve 31 separates from the sealing surface 41b of the valve seat body 41. A stainless steel base material and a Sn plated film softer than the base material form a smooth surface 42 on the sealing surface 41b of the valve seat body 41.

In a combustion unit, a fuel collision member is disposed between a fuel injection valve and a combustion chamber. The fuel collision member is positioned so that, a part of fuel injected from said fuel injection valve is introduced into the combustion chamber while colliding with the fuel collision member, and the other part of fuel is directly introduced into the combustion chamber without colliding with the fuel collision member. Thus, fuel introduced into the combustion chamber is atomized while being introduced into the combustion chamber in a wide range.
