Description
本発明の自動二輪車は、エンジンと、前記エンジンに供給する吸気を加圧する過給機と、前記過給機からの吸気を貯留する吸気チャンバとを備え、前記エンジンは、クランクシャフトを回転自在支持するクランクケースと、前記クランクケースの前部から上方に延びるシリンダと、前記シリンダ内部の燃焼室に燃料を噴射する直噴インジェクタと、前記直噴インジェクタに燃料を供給するポンプとを備え、前記過給機は前記クランクケースの上方で前記シリンダの後方に配置され、前記吸気チャンバは前記過給機および前記シリンダの上方に配置され、前記吸気チャンバの下方に前記直噴インジェクタが配置されている。 The motorcycle of the present invention includes an engine, a supercharger that pressurizes the intake air supplied to the engine, and an intake chamber that stores the intake air from the supercharger, and the engine rotatably supports a crank shaft. comprising a crankcase, a cylinder extending upward from a front portion of the crankcase, and direct injector for injecting fuel prior Symbol combustion chamber in the cylinder, a pump for supplying fuel to the direct injection injector that, the The supercharger is arranged above the crank case and behind the cylinder, the intake chamber is arranged above the supercharger and the cylinder, and the direct injection injector is arranged below the intake chamber. ..
吸気入口46aと吸気ポート60とが、シリンダヘッド46に形成された内部吸気通路69により連通されている。排気出口46bと排気ポート62とが内部排気通路71により連通されている。吸気入口46aから内部吸気通路69および吸気ポート60を介して、吸気が燃焼室45に供給され、燃焼室45で燃焼される。燃焼後の排気が、排気ポート62および内部排気通路71を介して排気出口46bから排出される。排気出口46bに排気管50が接続され、排気管50はエンジンEの下方で集合され、車体後方のマフラ(図示せず)に接続されている。 The intake inlet 46a and the intake port 60 are communicated with each other by an internal intake passage 69 formed in the cylinder head 46. The exhaust outlet 46b and the exhaust port 62 are communicated with each other by the internal exhaust passage 71. Intake air is supplied to the combustion chamber 45 from the intake inlet 46a via the internal intake passage 69 and the intake port 60, and is burned in the combustion chamber 45. The exhaust after combustion is discharged from the exhaust outlet 46b via the exhaust port 62 and the internal exhaust passage 71. An exhaust pipe 50 is connected to the exhaust outlet 46b, and the exhaust pipe 50 is assembled below the engine E and connected to a muffler (not shown) at the rear of the vehicle body.
一方、スロットルボディ72に、上流側インジェクタ75以外の吸気系部品76の少なくとも一つが設けられている。本実施形態では、スロットルボディ72の上部に、吸気系部品76の少なくとも一つが設けられている。吸気系部品76は、スロットルボディ72(吸気管)における吸気側動弁機構68寄りの部分に設けられている。本実施形態の吸気系部品76は、スロットルボディ72(吸気管)に取り付けられる部品である。吸気系部品76は、例えば、スロットル弁74の駆動装置、各種センサを含む。 On the other hand, the throttle body 72 is provided with at least one of the intake system components 76 other than the upstream injector 75. In the present embodiment, at least one of the intake system components 76 is provided on the upper portion of the throttle body 72. The intake system component 76 is provided in a portion of the throttle body 72 (intake pipe) near the intake side valve mechanism 68. The intake system component 76 of the present embodiment is a component attached to the throttle body 72 (intake pipe). The intake system component 76 includes, for example, a drive device for the throttle valve 74 and various sensors.
吸気通路における直噴インジェクタ80よりも吸気流れ方向上流側に、上流側インジェクタ75が設けられている。2つのインジェクタ75,80を設けることにより、自動二輪車やエンジンEの特性に応じて噴射量、噴射タイミングを調整して多様な制御を実現できる。例えば、エンジンの高回転状態など、直噴インジェクタ80の燃料噴射量では、気筒内の混合気に含まれる燃料が不足する場合、上流側インジェクタ75により燃料を追加噴射してもよい。また、上流側インジェクタ75がスロットル弁74の下流側に燃料F1を噴射しているので、スロットル弁74で絞られて流速が大きくなった空気によって燃料F1が燃焼室45に導入されるから、レスポンスを向上させることができる。 An upstream injector 75 is provided on the upstream side in the intake flow direction with respect to the direct injection injector 80 in the intake passage. By providing the two injectors 75 and 80, it is possible to realize various controls by adjusting the injection amount and the injection timing according to the characteristics of the motorcycle or the engine E. For example, when the fuel injection amount of the direct injection injector 80 is insufficient, such as in a high rotation state of the engine, the fuel contained in the air-fuel mixture in the cylinder may be additionally injected by the upstream injector 75. Moreover, since the upstream injectors 75 is injecting fuel F1 to the downstream side of the throttle valve 74, because fuel F 1 is introduced into the combustion chamber 45 by air throttled flow velocity is increased by the throttle valve 74 , The response can be improved.
