A vehicle control device applied to a vehicle including an internal combustion engine and an electrically heated catalyst which is warmed by applying a current, and includes a catalyst carrier supporting a catalyst and a carrier retention unit that retains the catalyst carrier and has an electrical insulation property. The control unit performs a control of suppressing a supply of an unburned gas from the internal combustion engine to the electrically heated catalyst so that the carrier retention unit is maintained at a lower temperature than the catalyst, when a condition for performing a fuel cut of the internal combustion engine during a deceleration is satisfied. Therefore, it is possible to suppress a rapid cooling of the catalyst, and it becomes possible to maintain a temperature of the carrier retention unit at a lower temperature than a temperature of the catalyst.

Catalyst Protection Against Hydrocarbon Exposure

Номер: US20160084135A1
Принадлежит: Caterpillar Inc

A system to protect an after treatment system from the effects of hydrocarbon accumulation on a catalyst. An engine system microprocessor using software estimates the amount of hydrocarbon accumulation on the after treatment system based on engine system parameters and other parameters. The accumulated hydrocarbons can cause an exothermic event if the catalyst temperature is allowed to ramp up too quickly. Similarly, accumulated hydrocarbon can temporarily reduce after treatment system performance. In the case of SCR, the microprocessor can control a reductant injector to modulate the amount of reductant being injected into the after treatment system to control the amount of ammonia slip. Alternatively or in addition to, the microprocessor can communicate with proper electronic control modules to modulate the engine system parameters such as engine speed, fuel, and back pressure to control engine exhaust flow temperature during operation of the engine system.
