Summary:To suppress an output of an engine from being excessively limited when an exhaust of particulate materials from the engine is required.SOLUTION: A vehicle includes an engine and a control device for controlling the engine within a range of upper-limit power or less when an exhaust of particulate materials from the engine is required to suppress. When the exhaust of particulate materials is required to suppress, the control device delays an ignition timing of the engine on the basis of a rotation speed of the engine and a load ratio thereof, in comparison with a time when an output of the particulate material is not required to suppress, and sets upper-limit power on the basis of the ignition timing.SELECTED DRAWING: Figure 5 【課題】エンジンからの粒子状物質の排出抑制が要求されているときに、エンジンの出力を余分に制限するのを抑制する。【解決手段】エンジンと、エンジンからの粒子状物質の排出抑制が要求されているときには上限パワー以下の範囲内でエンジンを制御する制御装置と、を備える車両であって、制御装置は、粒子状物質の排出抑制が要求されているときには、粒子状物質の排出抑制が要求されていないときに比してエンジンの回転数および負荷率に基づいてエンジンの点火時期を遅くすると共に、点火時期に基づいて上限パワーを設定する。【選択図】図５
