Abstract: A split cycle internal combustion engine comprising a compression cylinder accommodating a compression piston; a combustion cylinder accommodating a combustion piston; a crossover passage between the compression cylinder and the combustion cylinder arranged to provide working fluid to the combustion cylinder; a controller arranged to determine a peak temperature of combustion in the combustion cylinder based on a received indication of a peak temperature of combustion in the combustion cylinder; and a coolant system arranged to regulate a temperature of the working fluid supplied to the combustion cylinder; wherein, in response to determining that the peak temperature of combustion exceeds a selected threshold, the controller is configured to control the coolant system to regulate the temperature of the working fluid supplied to the combustion cylinder so that a peak temperature of combustion in the combustion cylinder is less than the selected threshold.

Abstract: A vertical wind-driven electricity generation device is described, which, in one embodiment, utilizes a segmented Savonius rotor and which is easily handled, transported, assembled and maintained, even by a single person. The blades of the rotor are segmented into a plurality of modest size blade segments, each of which comprises two, low height, helically-curved blade portions. The blade segments are preferably of the same height and diameter. The rotor is mounted on a central vertical shaft connected to a generator. When the plurality of blade segments are installed on the device's central shaft, the overall blade configuration functions as an unitary Savonius rotor. Flow of gas (normally air in the form of wind) causes the rotor to move, turning the shaft and rotating member of the generator to rotate, causing the generator to produce electricity.

Abstract: A vertical wind-driven electricity generation device is described, which utilizes a unique segmented Savonius rotor and which is easily handled, transported, assembled and maintained, even by a single person. The blades of the rotor are segmented into a plurality of modest size blade pair segments, each of which comprises two (or optionally, three or four) low height, helically curved blade portions. The blade pair segments are preferably of the same height and diameter. The rotor is mounted on a central vertical shaft connected to a generator. When the plurality of blade portions are installed on the device's central shaft, the overall blade configuration functions as an unitary Savonius rotor. Flow of gas (normally air in the form of wind) causes the segmented Savonius rotor to move, turning the shaft and rotating member of the generator to rotate, causing the generator to generate electricity.
