Abstract: 【課題】比較的高温になるバックプレートを効果的に冷却することができ、PCVを備える内燃機関に適用された場合にディフューザ壁面のデポジット堆積量を低減することができる過給機を提供する。【解決手段】過給機60のコンプレッサハウジングCHは、冷媒が通過する冷却通路ILを備え、バックプレートBPは、コンプレッサハウジングCHの部分であって前記冷却通路ILの壁面の一部又は全部を構成している部分と一体成型で構成されている。従って、高温となっているベアリングハウジング90から伝達される熱によって加熱されているバックプレートBPの熱を、比較的効率良く冷却することができ、第2ディフューザ壁部72bの温度上昇が抑制される。よって、ディフューザ部DFを通過するオイルミスト粒子OMの油分の蒸発が抑制され、粘着性を有するオイルミスト粒子OMへと変化し難く、堆積デポジットの量を低減することができる。【選択図】図2

Abstract: PROBLEM TO BE SOLVED: To suppress changes in an EGR gas amount due to a change in exhaust valve opening timing.SOLUTION: The control device of an internal combustion engine includes an internal EGR mechanism. The internal EGR mechanism recirculates exhaust gas to each cylinder of the internal combustion engine by temporarily opening an exhaust valve during the intake stroke of each cylinder of the internal combustion engine. When valve opening timing of the exhaust valve during a period from an expansion stroke to an exhaust stroke is advanced, the mechanism accordingly advances the valve opening timing of the exhaust valve in the intake stroke for exhaust gas recirculation.

Abstract: PROBLEM TO BE SOLVED: To provide a stop control device for an internal combustion engine capable of preventing a variation of a restart time.
SOLUTION: This stop control device for the internal combustion engine is provided with a flywheel, a magnetic material, an electromagnetic force generation means, and a control means. The flywheel is formed of a non-magnetic material and connected to a crankshaft of the internal combustion engine body.

Consequently, a piston can be stopped always at constant position in a cylinder. A time until the ignition of fuel injected into a cylinder during restarting, namely, the variation of the restart time of the internal combustion engine body can be prevented.
