Abstract (en)
[origin: WO2019229027A1] The invention relates to a method for managing the lightoff of a 3-way catalytic converter placed in an exhaust line of a petrol engine, said engine comprising cylinders each provided with at least one exhaust valve. The main characteristic of a method according to the invention is that it comprises the following steps: – a step of calculating the enthalpy H of the exhaust gases, making it possible to determine the amount of heat supplied to the catalytic converter, – a step of determining a threshold enthalpy value S that signals the lightoff of the catalytic converter, – a step of halting activation of the catalytic converter when the calculated value of the enthalpy H reaches the value of said threshold enthalpy S.
