Abstract:
A fuel reformer for a vehicle engine may include a housing including an inlet at a first end and an outlet at a second end of the housing through which exhaust gas flows, a reforming catalyst disposed between the inlet and the outlet to reform exhaust gas, a mixing chamber providing a space for mixing fluid between the inlet and the reforming catalyst, a fuel injector injecting a same fuel to be supplied to the engine into the mixing chamber, and an air injector coupled to the housing to supply air into the mixing chamber.
Abstract:
A volume measuring structure of a cylinder head and a piston for an engine includes: a cylinder block configured to form a frame of an engine and include a cylinder in which a piston reciprocates to generate power; a cylinder head configured to be mounted on the cylinder block to form a combustion chamber along with the cylinder and include an ignition plug which ignites the engine and a valve which opens and closes intake and exhaust passages; a first pressure sensor configured to be mounted in the cylinder block to determine a volume of the cylinder block; and a second pressure sensor configured to be mounted in the cylinder head to determine a volume of the cylinder head.
Abstract:
A thermoelectric generation device using engine waste heat includes: a thermoelectric element including a sheet-type graphite layer having thermal conductivity; first heat transfer bodies joined to the graphite layer at intervals and having thermal conductivity and electrical conductivity; second heat transfer bodies disposed between the first heat transfer bodies at intervals and having thermal conductivity and electrical conductivity; first pellets of a P-type thermoelectric material joined between the first and second heat transfer bodies alternately with second pellets of an N-type thermoelectric material. The second pellets are joined between the first and second heat transfer bodies alternately with the first pellets. In particular, at least one of the first pellet or the second pellet is joined in a line-contact to form an angle with an inclined portion of the adjacent heat transfer body and to form a surface-contact when the graphite layer is curved.
Abstract:
The present disclosure relates to a generator for an internal combustion engine. The generator for an internal combustion engine includes: a heat protector configured to cover an exhaust manifold in which exhaust gas flows to absorb heat energy emitted from the exhaust manifold; and a thermoelectric module configured to be disposed on the heat protector to generate electric energy from heat energy absorbed by the heat protector.
