Fuel control system

The invention is concerned with a method of deriving mechanical work from a combustion gas in internal combustion engines and reciprocating internal combustion engines for carrying out the method. The invention includes methods and apparatuses for managing combustion charge densities, temperatures, pressures and turbulence in order to produce a true mastery within the power cylinder in order to increase fuel economy, power, and torque while minimizing polluting emissions. In its preferred embodiments, the method includes the steps of (i) producing an air charge, (ii) controlling the temperature, density and pressure of the air charge, (iii) transferring the air charge to a power cylinder of the engine such that an air charge having a weight and density selected from a range of weight and density levels ranging from below atmospheric weight and density to heavier-than-atmospheric weight and density is introduced into the power cylinder, and (iv) then compressing the air charge at a lower-than-normal compression ratio, (v) causing a pre-determined quantity of charge-air and fuel to produce a combustible mixture, (vi) causing the mixture to be ignited within the power cylinder, and (vii) allowing the combustion gas to expand against a piston operable in the power cylinders with the expansion ratio of the power cylinders being substantially greater than the compression ratio of the power cylinders of the engine. In addition to other advantages, the invented method is capable of producing mean effective cylinder pressures ranging from lower-than-normal to higher-than-normal. In the preferred embodiments, the mean effective cylinder pressure is selectively variable (and selectively varied) throughout the mentioned range during the operation of the engine. In an alternate embodiment related to constant speed-constant load operation, the mean effective cylinder pressure is selected from the range and the engine is configured, in accordance with the present invention, such that the mean effective cylinder pressure range is limited, being varied only in the amount required for producing the power, torque and speed of the duty cycle for which the engine is designed.

Internal combustion engine and working cycle

A method of operating an internal combustion engine, including at least one cylinder and a piston slidable in the cylinder, may include supplying pressurized air from an intake manifold to an air intake port of a combustion chamber in the cylinder, selectively operating an air intake valve to open the air intake port to allow pressurized air to flow between the combustion chamber and the intake manifold substantially during a majority portion of a compression stroke of the piston, and operably controlling a fuel supply system to inject fuel into the combustion chamber after the intake valve is closed.

Air and fuel supply system for combustion engine

A fuel intake system for a supercharged automotive engine having at least one engine cylinder with first and second fuel intake ports and exhaust port comprises first fuel intake passage communicated at one end to the first fuel intake port and at the other end to the supercharger through a first throttle valve, and a second fuel intake passage communicated at one end to the second fuel intake port and at the other end to the supercharger through a second throttle valve. These intake and exhaust ports are adapted such that the first fuel intake port opens at a timing preceding the closure of the exhaust port and the second fuel intake port opens after the opening of the first fuel intake port.

Plural intake system for supercharged engine

Engines and methods of controlling an engine may involve one or more fluidically driven actuators associated with engine intake and/or exhaust valves. In some examples, the actuators may be placed in flow communication with high pressure fluid from one source and/or low pressure fluid from another. Timing of valve closing/opening and use of an air supply system may enable engine operation according to a Miller cycle.

Combustion engine including fluidically-driven engine valve actuator

Device for the permanent atomization of liquid fuel into Diesel engines comprising a volumetric pump interposed in the engine air induction pipe, whereby pipes for delivering liquid fuels and additives, such as oil, open through jets into said air induction pipe, upstream of the volumetric gear pump operated simultaneously as a pump and as an atomizer.
