An Otto cycle is an idealized thermodynamic cycle that describes the functioning of a typical spark ignition piston engine. It is the thermodynamic cycle most commonly found in automobile engines. The Otto cycle is a description of what happens to a mass of gas as it is subjected to changes of pressure, temperature, volume, addition of heat, and removal of heat. The mass of gas that is subjected to those changes is called the system. The system, in this case, is defined to be the fluid (gas) within the cylinder. By describing the changes that take place within the system, it will also describe in inverse, the system's effect on the environment. In the case of the Otto cycle, the effect will be to produce enough net work from the system so as to propel an automobile and its occupants in the environment.
Gaseous and dual fuel intake system for diesel and gasoline engines
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.

Pressure control method and device of an intake manifold of an otto cycle internal combustion engine
Method of controlling a pressure in an intake manifold (IT) of an Otto cycle internal combustion (E) engine, equipped with a throttle valve (TH) and an electric actuator (Act) arranged to control a target position (αdes) of a shutter (SH) of the butterfly valve and a pressure sensor (Sns), the method comprising a control procedure (CTRL) of the actuator as a function of a first pressure error between a value of target pressure ( Pd.es ) and an estimated pressure value (Pcalc), in which the estimate of the estimated pressure value (Pcalc) is a function of a second error (Ectrl) between an average value (Pmeas_filt) of the measured pressure and an average value ( Pcalc_filt) of the estimate (Pcalc) of the pressure value.
