This is a system for generating hydrogen on-board the vehicle from compressed natural gas (CNG) in select ratios to create hydrogen-enriched CNG (HCNG) fuel for use in internal combustion engines. The on-board generation of hydrogen is comprised of a reforming system of CNG fuel with direct contact with exhaust gases. The reforming system controls for production of HCNG fuel mixtures is based on specific engine operating conditions. The vehicle's engine controls and operating parameters are modified for combustion of selective ratios of HCNG fuel mixtures throughout engine operating cycle. The reforming system controls and engine controls modifications are also used to minimize combustion emissions and optimize engine performance.

A reactor as a heat treatment device includes heat transfer structures removably placed in first flow channels, a first information acquisition unit connected to the inlet side of the first flow channels to acquire information for specifying a temperature and a flow rate of the first fluid which are reference conditions after lapses of time, a second information acquisition unit connected to the outlet side of the first flow channels to acquire the information for specifying the temperature of the first fluid after each lapse of time, and a control unit that calculates a heat exchange amount after each lapse of time in accordance with the temperature and the flow rate specified according to the information acquired by the first information acquisition unit and the second information acquisition unit, so as to estimate a service life of the heat transfer structures in accordance with the heat exchange amount.
