The present invention relates to an internal combustion engine with hydrogen direct injection. The engine derives from a traditional diesel cycle engine but is modified and optimized to be powered by hydrogen. Some main characteristics of the injection, ignition and combustion systems of direct fuel injection engines are modified. In particular: the piston and specifically the combustion chamber, the “lay-out” of the injector and the lay-out of the spark plug. The invention is applicable to various types of engines with different bores, cylinder head arrangement, rotation speeds and type of mission. The components can be customized accordingly, while maintaining the commonalities with the corresponding components of traditional diesel engines.

The invention relates to a reciprocating internal combustion engine with direct injection operating according to a modified Otto or Diesel cycle in order to re- duce the operating temperature, when maximum power is not required, with a consequent reduction in heat loss. The engine subject of the invention absorbs minimal power in the suction phase and makes it possible, when maximum power is not required, to increase the compression ratio and consequently the efficiency. The engine subject of the invention provides, for each cylinder, the use of two check valves in the suction pipe and a motorized inlet valve whose opening cycle varies according to the required power. According to a variant of the engine subject of the invention, the latter allows the replacement of the re- sidual burnt gases present in the combustion chamber of each cylinder with air and recirculated gases, pre-loading one of the two check valves mentioned above. The engine subject of the invention therefore allows the replacement of the residual burnt gases with air in order to further reduce the operating tem- peratures of the engine at the same required power, or to increase its filling, and therefore the power, at the same operating cycle.

The invention involves a system and method for providing a liquid fuel or a liquid and gaseous fuel to a diesel cycle or Otto cycle engine for operation of the engine. The system includes a primary electronic control module (ECM) which monitors engine sensors and contains least one three-dimensional (3D) fuel map for the liquid fuel and one for gaseous fuel. A gaseous fuel injection assembly is provided for the injection of the gaseous fuel to the engine. The gaseous fuel is transported on the vehicle in a liquid form and converted to a gaseous fuel via a fuel phase converter utilizing the air being drawn into the engine by the combustion process. The liquid fuel is warmed while the incoming air is cooled to increase air density of the air being drawn into the engine, thereby increasing engine performance and lowering the emissions output of the engine.

This invention is about a hydrogen-generating device, with low energy consumption and high electrode durability, for diesel cycle engines. The hydrogen-generating device comprises: an electrolysis cell made of aluminum, containing heat exchanger fins on the outside, an electrolytic solution, two electrodes; a hydrogen transport system to be injected into the engine's air intake system; an electronic module for direct voltage control, used in electrolysis, of the electrode polarity alternation time, of the volume of hydrogen in a mixture of constant hydrogen / oxygen composition to be injected into the engine in a variable manner, thus injecting a quantity of up to 10% of the hydrogen:oxygen mixture, in the ratio of 65:35, per liter of diesel consumed, in a volume / volume ratio.
