Title:
内燃機関の触媒早期暖機制御装置
Document Type and Number:
Japanese Patent JP4310917
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To control catalyst early warming-up with high exhaust temperature rise effect while ensuring the stability in combustion. SOLUTION: In a hybrid vehicle, the correction of an ignition timing lag is executed combinedly with the correction of the increase of a power generating energy of a generator motor 12 for raising a catalyst temperature corresponding to a target catalyst temperature rise characteristic in controlling the catalyst early warming-up, and an intake air amount (throttle opening) is increased and corrected to compensate the lowering of the engine output due to the correction of the ignition timing lag and the correction of the increase of the power generating energy. Whereby the ignition timing lag is corrected within a range not impairing the stability in combustion, and the exhaust temperature is raised, and the insufficient exhaust heat can be ensured by increasing and correcting the power generating energy (increase of intake air amount). That is, the exhaust heat insufficient only by the increase and correction of the power generation energy can be secured by correcting the ignition timing lag, and the correction amount of the ignition timing lag causing the impairing of the stability in combustion can be reduced.
