Abstract:
The present subject matter describes a cylinder head assembly (100) of an internal combustion engine. The cylinder head assembly (100) comprises a combustion chamber, a cylinder head (105), a fuel supply device (115) for supplying fuel to the combustion chamber and an intake pipe (110). The cylinder head (105) has a plurality of intake ports (215) for injecting fuel into the combustion chamber. The intake ports (215) include a first intake port (215b) and a second intake port (215a). The intake pipe (110) connects the fuel supply device (115) with the intake ports (215). The intake pipe (110) includes a plurality of intake passages (120) that aligns with corresponding intake ports (215) for supplying fuel to the intake ports (215). The fuel supply device (115) supplies the fuel to the first intake port (215b) and thereafter to the second intake port (215a) based on throttle input.
Abstract:
An internal combustion engine is configured with combustion chamber pressure sensing and exhaust gas recirculation apparatus. Exhaust gas recirculation control includes closed-loop controlling exhaust gas recirculation apparatus in accordance with a predetermined control target. Adjustments to the control target are made based on combustion chamber pressure information.
Abstract:
An internal combustion engine (100) having a combustion chamber (102) and a fuel delivery system (106) for delivering fuel into the combustion chamber (102). The fuel delivery system (106) includes a fuel entry (116) proximate the combustion chamber (102), a combustion compression wave reflection conduit (112) connected to the combustion chamber (102) proximate the fuel entry (116), and a movable member (114) located proximate the reflection conduit (112) for at least partially opening and closing a path (120) through the reflection conduit (112).
Abstract:
An apparatus and method of enhancing fuel combustion by organizing an amount of transformed water with a high level of stored energy into a geometric arrangement such that a central cavity is created that substantially surrounds a segment of a fuel line leading to a combustion device such as an internal combustion engine. The fuel passes within the space surrounded by the transformed water and becomes imprinted with a molecular clustering as a result of water memory transfer at a lower level of stored energy. This process alter the properties of the fuel allowing it to be utilized with a higher level of efficiency and with lower emissions of pollutants such as hydrocarbons and carbon monoxide.
Abstract:
A method of controlling combustion of an air-fuel charge in a piston engine having at least one combustion chamber comprising, (a) mixing at least one hydrocarbon fluid fuel and no more than about 10,000 ppm of at least one combustion initiating additive to thereby produce a fluid fuel mixture; (b) combining the fluid fuel mixture with a gaseous medium containing oxygen thereby producing an air-fuel charge; (c) supplying the air-fuel charge to the at least one combustion chamber; (d) compressing the air-fuel charge with a piston in the at least one combustion chamber; and (e) igniting the air-fuel charge with at least one light source.
Abstract:
Fuel-powered actuators are described wherein actuation is a consequence of electrochemical processes, chemical processes, or combinations thereof. These fuel-powered actuators include artificial muscles and actuators in which actuation is non-mechanical. The actuators range from large actuators to microscopic and nanoscale devices.
Abstract:
The present invention concerns a device for fuel injection intended for an internal combustion engine with a wide range of speeds of revolution and with high requirements for rapid response such as, for example, the engine in a motor cycle, and a method of controlling fuel injection to such an engine. In the invention according to the present application the fuel injection to an internal combustion engine comprising an intake pipe (1) with at least one intake valve (2) and one or more injectors is controlled in such a manner that a first fuel injection in order to obtain a well prepared air/fuel mixture occurs early in the working cycle of the engine following the closure of the intake valve and a second fuel injection in order to obtain an optimal amount of fuel for the cycle, a process known as "transient compensation", occurs late in the working cycle before closure of the intake valve.
