An internal combustion engine, ICE, system for a vehicle includes an ICE operable on a main fuel component containing hydrogen gas or hydrogen liquid, said ICE having at least one combustion chamber; an exhaust gas aftertreatment system, EATS, arranged in an exhaust gas circuit downstream the ICE…
The condensed water processing device determines (S2) whether the pH of condensed water stored in the condensed water tank is smaller than a threshold value (t). When the pH of condensed water is smaller than the threshold value (t), the supply quantity of urea water being supplied to the upstream…
The condensed water treatment device obtains (S1) the storage water quantity (QW) of a condensed water tank, and drains (S4) condensed water in the condensed water tank when the storage water quantity (QW) is larger than a threshold value (tu) and also urea water is supplied to an exhaust passage…
A condensed water treatment device determines whether a storage water quantity Qw of condensed water generated in an EGR cooler and stored in a condensed water tank is equal to or less than a lower limit t1 (S2). When the storage water quantity Qw is equal to or less than the lower limit t1, the…
The invention relates to a water injection system (1) for an internal combustion engine (6), comprising a water tank (2), at least one pump (3) and at least one water injector (4), wherein water can be pumped from the water tank (2) to the water injector (4) by the pump (3) and water can be…
In a stratification operation, O 2 is injected from an oxygen injector 24 during valve opening of an intake valve 26. Therefore, the injected O 2 flows into a combustion chamber 14 immediately after the injection, and forms a layer having a constant spread in the combustion chamber 14 (A in Figure…
The device (1) has a condenser (2) that is arranged for condensing a water vapor contained in an exhaust gas of an internal combustion engine into water in an exhaust gas system. The water is collected in a collecting container (3) of a water injection system for the re-injection to a combustion…
A combustion chamber (CC) to which a reactant and a working gas whose specific heat ratio is higher than that of air are supplied and in which the working gas can expand following a reaction of the reactant, a circulation path (20) capable of re-supplying the working gas into the combustion chamber…
