Abstract
This invention relates to a fuel-supply device for methanol engines. The constant-temperature-heating methanol reforming system comprises an electrically controlled methanol nozzle, a reforming chamber, and multiple reforming columns in the reforming chamber. Catalyst layers are set on the surface of the reforming columns as well as the inner wall of the reforming chamber for promoting methanol reforming. A PTC constant-temperature-heating element is set out of the reforming chamber, and connected with one end of a spring leaf. The other end of the spring leaf is connected with an electrode, which is fixed on the reforming chamber by an insulating block. This invention solves the problems of the difficulty of methanol cold-start as well as the emission of harmful formaldehyde intermediate during methanol combustion. In this invention, methanol is firstly introduced into the constant-temperature-heating reforming system to generate H2 and CO, which are then supplied to the engines for combustion. This invention thus has such advantages as no formaldehyde emission, better cold-start performance and little exhause pollution.
