Title: Improvements to operations of engines
Inventor: PETER RICHARD MARTIN
IPC: F02D15/02
Filed: 2017-02-02
Abstract: A method of improving the efficiency of an internal combustion engine 1 having a piston 15 configured for reciprocating movement within a cylinder 16. The rate of movement of the piston 15 along the cylinder 16 with respect to a combustion chamber is at least reduced during at least a part of the first 90 degrees of each combustion stroke. The reduction is applied to each cycle of the engine such that the path of the piston 15 during each cycle of the engine is cyclic but not sinusoidal for at least part of the first 90 degrees of the combustion stroke. The combustion is also enhanced by providing a primary hydrocarbon based fuel for igniting in the combustion chamber. A secondary hydrocarbon based fuel is also introduced into the combustion chamber, the lower flammability limit (LFL) being higher than the LFL of the primary fuel. The concentration of the secondary fuel is less than or equal to its LFL relative to the amount of air in the combustion chamber. Combustion of the primary fuel causes the temperature and pressure of the secondary fuel to increase and experience pyrolysis and chemical decomposition.

Title: Systems and methods for dynamic range enhancement using an open-loop modulator in parallel with a closed-loop modulator
Inventor: Ramin Zanbaghi
IPC: H03F3/217
Filed: 2015-10-20
Abstract: An integrated circuit may have two signal paths: an open-loop modulator (22) with a digital-input Class-D amplifier and a closed-loop modulator (24) with an analog-input Class-D amplifier. A control subsystem (20) may be capable of selecting either the open-loop modulator (22) or the closed-loop modulator (24) as a selected path based on one or more characteristics (e.g., signal magnitude) of an input audio signal (DIG_IN). For example, for higher-magnitude signals, the closed-loop modulator (24) may be selected while the open-loop modulator (22) may be selected for lower-magnitude signals. In some instances, when the open-loop modulator (22) is selected as the selected path, the closed-loop modulator (24) may power off, which may reduce power consumption.
