摘要： A variety of methods and arrangements for improving the fuel efficiency of internal combustion engines based on skip fire operation of the engine are described. In one aspect the skip fire decisions are made on a working cycle by working cycle basis. During selected skipped working cycles, the corresponding cylinders are deactivated such that air is not pumped through the cylinder during the selected skipped working cycles. In some implementations, the cylinders are deactivated by holding associated intake and exhaust valves closed such that an air charge is not present in the working chamber during the selected skipped working cycles.

摘要： A method for enhancing engine brake horsepower. The method includes generating an engine brake horsepower by compressing air in a cylinder of an engine. Additionally, fuel is injected into the compressed air in the cylinder. The injected fuel is combusted in the compressed air in the cylinder prior to the piston reaching the top dead center position in the at least one cylinder. The compressed combustion products are also released before the piston passes the top dead center position. The combustion of the fuel during the engine braking event allows the engine braking to be a throttable event. Further, the quantity of fuel introduced into the cylinder for combustion may be adjusted so that the engine braking horsepower remains relatively consistent despite changes in engine speed.

摘要： The present invention relates to system and methods for improving efficiency of an internal combustion engine. This system may include a fuel processor. The system receives instructions for a desired engine output and operating conditions. The system may then determine an operational state corresponding to the desired output. The operational state includes designating the cylinders into one of three categories: working, deactivated and passive. The number of working cylinders is calculated by dividing the desired output by the power provided by one cylinder operating at substantially optimal efficiency. Then the system substantially disables fuel flow to and air flow to the deactivated cylinders, substantially disables fuel flow to and firing of the passive cylinders, and substantially regulates fuel flow to, air flow to and firing of the working cylinders. Firing of the working cylinders is synchronized with engine speed to reduce unwanted engine vibrations. The number of working, passive and deactivated cylinders may be continually altered in response to changes in desired output or operating conditions.

摘要： A variety of methods and arrangements for improving the fuel efficiency of internal combustion engines are described. Generally, an engine is controlled to operate in a skip fire variable displacement mode. Feedback control is used to dynamically determine the working cycles to be skipped to provide a desired engine output. In some embodiments a substantially optimized amount of air and fuel is delivered to the working chambers during active working cycles so that the fired working chambers can operate at efficiencies close to their optimal efficiency. In some embodiments, the appropriate firing pattern is determined at least in part using predictive adaptive control. By way of example, sigma delta controllers work well for this purpose. In some implementations, the feedback includes feedback indicative of at least one of actual and requested working cycle firings. In some embodiments, the appropriate firings are determined on a firing opportunity by firing opportunity basis. Additionally, in some embodiments, an indicia of the current rotational speed of the engine is used as a clock input for a controller used to selectively cause the skipped working cycles to be skipped.
