The invention relates to a water injection device (1) of an internal combustion engine, comprising a water tank (5) for storing water, at least one water injector (6), a pump element (3) for pumping water out of the water tank (5) into the water injector (6), and a blocking element (11) which is arranged in a region (8a) between the pump element (3) and the water injector (6) and which is designed to keep a system pressure between the blocking element (11) and the water injector (6) at a level such that the water located in the region (8a) is prevented from evaporating. The invention further relates to an internal combustion engine which comprises a water injection device (1) according to the invention.
摘要:
An internal combustion engine includes a combustion chamber. The chamber includes a body that is movable in the chamber to vary the chamber volume and contains a catalyst. First valving is operable to admit an intake gas into the chamber and second valving connected with an aqueous fluid supply system is operable to admit an aqueous fluid and a steam reforming fuel into the chamber. A controller is configured to cause the second valving to admit a aqueous fluid and an amount of the steam reforming fuel into the chamber and when a predetermined condition exists in the chamber during compression of the intake gas to absorb heat generated by the compression of the intake gas in the presence of the catalyst to promote a steam reformation process to separate hydrogen from the steam reforming fuel or the aqueous fluid.
摘要:
A method for driving an internal combustion engine is a method for reducing nitrogen oxides in emissions of the internal combustion engine, and includes a process of introducing air, which has a low oxygen concentration and contains no emissions, into the internal combustion engine, and a process of mixing humidifying water with a hydrocarbon fuel and injecting the mixture into a combustion chamber of the internal combustion engine as an emulsion fuel.

An apparatus including a reciprocating internal combustion engine with at least one piston and cylinder set and an intake stream; at least one liquid atomizer in fluid communication with the intake stream operable to provide a plurality of liquid droplets with a diameter less than 5 μm to the intake stream; and a controller where the controller is able to adjust an index of compression for the engine by: calculating a wet compression level in response to an engine operating limit and adjusting the at least one liquid atomizer in response to the wet compression level.
摘要:
The invention relates to a method for determining the viscosity of a fuel/water or water/fuel emulsion in a fuel line, comprising the following step: measuring the viscosity of the emulsion by way of a first measurement method, characterized by the following further steps: measuring the water content of the emulsion; determining the viscosity of the emulsion by allocating the value measured by way of the first measurement method to a value, which has been predetermined by way of a second measurement method, for an emulsion having a water content corresponding to the measured water content, wherein the second measurement method is more precise than the first measurement method.
