The Diesel cycle is a combustion process of a reciprocating internal combustion engine. In it, fuel is ignited by heat generated during the compression of air in the combustion chamber, into which fuel is then injected. This is in contrast to igniting the fuel-air mixture with a spark plug as in the Otto cycle (four-stroke/petrol) engine. Diesel engines are used in aircraft, automobiles, power generation, diesel-electric locomotives, and both surface ships and submarines.
Direct injection internal combustion reciprocating engine and thermodynamic cycle according to which said engine can operate
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.

Hydrogen generation device for optimising combustion and reducing the emission of pollutants in diesel cycle engines
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.
