CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

A control device predicts whether temporary reduction occurs to a charging efficiency of fresh air in an in-cylinder gas by an influence of an EGR rate of the in-cylinder gas, which increases later than increase of a charging efficiency of the in-cylinder gas, if a first arithmetic operation is applied to calculating a target throttle opening degree based on a target charging efficiency which is increasing, in a case of shifting to an acceleration operation, by using a prediction model expressing dynamic characteristics of an internal combustion engine. When it is predicted that temporary reduction occurs to the charging efficiency of the fresh air, the control device calculates the target throttle opening degree by a second arithmetic operation by which an increase speed of a throttle opening degree is restrained more than by the first arithmetic operation, instead of calculating the target throttle opening degree by the first arithmetic operation.

INTERNAL COMBUSTION ENGINE

Oxygen injection system

The design and construction of past oxygen injection systems having an oxygen mixer to inject oxygen into an air intake pipe required the use of oxygen in a highly pressurized state. The use of high pressure oxygen required precise pressure control in order to maintain safety. Additionally, the high pressure tank used for storing the oxygen was not space efficient due to the large volume occupied by the oxygen in the gaseous state. The present invention overcomes these problems by utilizing oxygen in the liquid state. Liquid oxygen is stored within a more space efficient storage tank. A solenoid is signaled through an electronic control unit to open under specific operating conditions allowing liquid oxygen to flow from the storage tank. Upon leaving the storage tank, the liquid oxygen is converted to a gaseous state where it flows through an oxygen supply pipe so that the oxygen can be injected by an oxygen mixer into an air intake pipe for mixing with ambient air.

Fuel injection control device for internal combustion engine

An internal combustion engine includes a direct injection valve that directly inject gaseous fuel from an injection hole into a cylinder by separating a needle from a seat, and a blow-by gas treating device that recirculates blow-by gas from a crankcase to an intake passage. The control device executes a suction process of suctioning gas in the cylinder into an injection hole of the direct injection valve when the blow-by gas is being recirculated by the blow-by gas processing device.

内燃機関の燃料噴射制御装置

【課題】気体燃料を噴射する筒内噴射弁が備えるシートの摩耗を抑える。【解決手段】内燃機関１０は、ニードルをシートから離間させることにより噴孔から気体燃料を気筒内に直接噴射する筒内噴射弁８４と、クランクケース１９から吸気通路へのブローバイガスの還流を行うブローバイガス処理装置とを備えている。制御装置１００は、ブローバイガス処理装置によるブローバイガスの還流が行われているときに気筒内のガスを筒内噴射弁８４の噴孔内に吸入する吸入処理を実行する。【選択図】図１

内燃機関制御装置

【課題】内燃機関を搭載する車両の燃費を向上させ、内燃機関の損傷を防止する内燃機関制御装置を提供する。【解決手段】内燃機関制御装置２０のインジェクタ２１は、エンジンの燃焼室に燃料を噴射可能である。酸化促進剤供給部２２は、燃焼室に酸化促進剤を供給可能である。アクセル開度検出部２３は、アクセルペダル１０の操作量であるアクセル開度Ｒｃを検出可能である。回転数検出部２４は、エンジン回転数Ｎを検出可能である。噴射量演算部３１は、アクセル開度Ｒｃおよびエンジン回転数Ｎに基づいて、燃料噴射量Ｑｆを演算可能である。燃焼方式設定部３２は、エンジン回転数Ｎおよび燃料噴射量Ｑｆに基づいて、エンジンの燃焼モードＭｃを設定可能である。供給量演算部３３は、燃焼モードＭｃに基づいて、酸化促進剤量Ｑｏを演算可能である。【選択図】図２
