    摘要： In a hybrid vehicle of the invention, in the event of specification that an exhaust treatment catalyst is in a preset adequate state at step S112, combustion control of an engine starts after a decrease of an intake pipe pressure P to a preset reference negative pressure Pref and reduction of an intake air flow into a cylinder of the engine by engine motoring. In the event of specification that the exhaust treatment catalyst is not in the preset adequate state but in an inadequate state at step S112, on the other hand, the combustion control of the engine immediately starts, prior to the decrease of the intake pipe pressure P to the preset reference negative pressure Pref. The hybrid vehicle of the invention allows an early start of the combustion control in a lower catalyst temperature condition that lowers the catalytic conversion power of the exhaust treatment catalyst and in a higher catalyst temperature condition that causes accelerated deterioration of the exhaust treatment catalyst in exposure to the air. The early start of the combustion control effectively reduces the potential shocks on a start of the engine, while preventing the potential troubles, for example, the worsened emission and the accelerated deterioration of the exhaust treatment catalyst, arising in the course of engine motoring due to the inadequate state of the exhaust treatment catalyst.

    摘要翻译： 在本发明的混合动力车辆中，在步骤S112中规定废气处理催化剂处于预先设定的适当状态的情况下，发动机的燃烧控制在进气管压力P降低至预先设定的基准负压 通过发动机起动来减少进入发动机气缸的进气流量。 在规定废气处理催化剂不处于预设适当状态但在步骤S112处于不充分状态的情况下，发动机的燃烧控制在进气管压力降低之前立即开始 P到预设参考负压Pref。 本发明的混合动力车辆能够在较低的催化剂温度条件下早期开始燃烧控制，其降低排气处理催化剂的催化转化率，并且在较高的催化剂温度条件下，导致废气处理催化剂暴露于 空气。 燃烧控制的早期开始有效地减少了发动机起动时的潜在冲击，同时防止了在发动机运转过程中引起的排气处理催化剂的恶化和加速劣化等潜在的问题， 废气处理催化剂的状态不足。

    摘要： The start control procedure of the invention lags an open-close timing VVT of an intake valve, restricts a throttle opening TH of a throttle valve, and starts cranking an engine with a lower torque Tlow. When a pressure Pf of a fuel supplied to in-cylinder fuel injection valves reaches or exceeds a preset reference value, which is greater than a sum of an in-cylinder compression pressure Pin and a closed valve position-retaining pressure Pcv of the in-cylinder fuel injection valves, the start control procedure cranks the engine with a standard cranking torque Tset. The start control procedure then starts advance of the open-close timing VVT of the intake valve, cancels the restriction of the throttle opening TH, and starts fuel injection from the in-cylinder fuel injection valves. This arrangement enables the fuel pressure Pf to quickly rise to or above the sum of the in-cylinder compression pressure Pin and the closed valve position-retaining pressure Pcv, and thereby effectively prevents the in-cylinder fuel injection valves from being inadequately opened.

    摘要翻译： 本发明的起动控制程序滞后于进气门的开闭正时VVT，限制了节流阀的节气门开度TH，并开始以较低的转矩Tlow启动发动机。 当供给到缸内燃料喷射阀的燃料的压力Pf达到或超过预先设定的基准值，该预设基准值大于缸内压缩压力Pin与内燃机燃料喷射阀的关闭阀位置保持压力Pcv之和时， 气缸燃油喷射阀，起动控制程序用标准起动转矩Tset曲柄发动机。 起动控制程序然后开始进气门的开关定时VVT的前进，消除节气门开度TH的限制，并开始从缸内燃料喷射阀的燃料喷射。 由此，能够使燃料压力Pf快速上升至缸内压缩压力Pin和关闭阀位置保持压力Pcv的总和以上，从而有效地防止缸内燃料喷射阀的打开不充分。
