Control of hybrid vehicle to ensure exhaust pollution does not rise while fuel supply is cut during energy recuperation mode of vehicle, uses monitoring of catalytic converter temperature to control blocking of external air

摘要

The supply of fuel to the engine is monitored (50) and the temperature of the catalytic converter (66) in the exhaust is measured (68). If the fuel supply is interrupted and the converter temperature falls below a set threshold, the flow of external air in the exhaust system is reduced (28,12).
