    Abstract: A combined ignition and fuel supply system for an internal combustion engine is described. The system comprises an ignition unit and a blending/dosing device (10) comprising a valve and equipped with an entrance duct (12) for the combustive agent, usually air, an entrance duct (14) for the fuel and an exit duct (16) for the fuel-combustive agent blend. The exit duct (16) is hydraulically connected to an aspiration manifold (18) which introduces the fuel-combustive agent blend into the cylinder (20) of the engine. Downstream of the valve of the blending/dosing device (10) and upstream of the cylinder (20), there is at least one pressure sensor (22) used to identify the pressure value of the fuel-combustive agent blend inside the aspiration manifold (18), in order to optimise fuel consumption and/or improve performance, varying the advance in relation to the pressure value in the aspiration manifold (18) and the engine revs.

    Abstract: The present invention relates to an arrangement and a method for estimating a fuel mixture's content of a supplementary fuel. A combustion engine (1) is provided with a so-called common rail system with a high-pressure pump (6) and an accumulator tank (7) for storage of the fuel mixture before it is injected into the engine (1). The arrangement comprises a control unit (9) adapted to determining the pressure change (Δρ) in an accumulator tank (7) within a period of time (Δt) on the basis of pressure values from a pressure sensor (7a), to providing information about a corresponding pressure change (Δρ 0 ) on a reference mixture with a known content of the supplementary fuel within a corresponding period of time (Δt) and to estimating the fuel mixture's content of the supplementary fuel by comparing the pressure change (Δρ) on the fuel mixture with the pressure change (Δρ 0 ) on the reference mixture. Conducting said estimation in operating situations where the high-pressure pump (6) pressurises a maximum volume of the fuel mixture while at the same time no fuel is injected into the engine results in estimation with very good accuracy.

    Abstract:  ディーゼルエンジンの圧縮行程において、筒内温度が750Kに達するまでに燃料噴射が終了するように、インジェクタから気筒内に微小燃料噴射量の噴射を行う。筒内温度が750Kに達した時点から900Kに達するまでの期間中、燃料の燃焼に伴う熱エネルギ量を低温酸化反応エネルギ量として積算する。微小燃料噴射量での総燃料が燃焼した場合の熱エネルギ量を総エネルギ量とし、総エネルギ量に対する低温酸化反応エネルギ量の割合をエネルギ割合として求める。このエネルギ割合をセタン価判定マップに当て嵌め、このセタン価判定マップから燃料のセタン価を抽出する。
