Claims (1)
気ポンプと、シリンダの排気ポートをクランク軸
の回転に同期して開閉する排気ロータリバルブと
、エンジンの燃焼室内に燃料を直接噴射するイン
ジエクタとを備えた筒内直噴式２サイクルエンジ
ンにおいて、 クランクケース内にセパレータを有するブロー
バイ通路を掃気ポートに連通し、上記セパレータ
より掃気ポート側のブローバイ通路中に、掃気の
流入を阻止する逆止弁を介設してなる筒内直噴式
２サイクルエンジンのブローバイガス還流装置。[Scope of claim for utility model registration] A scavenging pump that pumps intake air to the scavenging port of the cylinder, an exhaust rotary valve that opens and closes the exhaust port of the cylinder in synchronization with the rotation of the crankshaft, and a scavenging pump that pumps the intake air into the scavenging port of the cylinder, an exhaust rotary valve that opens and closes the exhaust port of the cylinder in synchronization with the rotation of the crankshaft, and a scavenging pump that pumps the intake air into the scavenging port of the cylinder. In an in-cylinder direct injection two-stroke engine equipped with an injector, a blow-by passage having a separator in the crankcase is communicated with a scavenging air port, and scavenging air is prevented from flowing into the blow-by passage on the side of the scavenging air port from the separator. A blow-by gas recirculation device for an in-cylinder direct injection 2-stroke engine that includes a check valve.
