20170167365 | HIGH PRESSURE ENERGY STORAGE THERMAL ENERGY POWER MACHINE AND WORK-DOING METHOD THEREFOR - Disclosed is a high-pressure energy storage thermal energy power machine. A gasifier is arranged on an exhaust duct on a cylinder head of an internal combustion engine. The gasifier is provided with gasifying plates in the direction of parallel air flow. Gas holes are arranged on the gasifying plates. The bottom portion of the gasifier is provided with a working medium inlet. Gasifying plates are distributed with gaps. Gas holes are distributed in an array on the gasifying plates. An energy storage chamber is arranged on the cylinder head. The gasifier is connected to the energy storage chamber. The energy storage chamber is connected to a high-pressure valve. The high-pressure valve is arranged on the cylinder head and above the cylinder block. The ratio of the volume of the energy storage chamber to the volume of the cylinder of the internal combustion engine is 1:1-3. | 2017-06-15 |
20170167366 | AN INTERNAL COMBUSTION ENGINE - An internal combustion engine includes a first low-pressure cylinder housing a first low-pressure piston, and a first high-pressure cylinder housing a first high-pressure piston, the first high-pressure cylinder being arranged in upstream fluid communication with the first low-pressure cylinder for providing exhaust gas into the first low-pressure cylinder. The internal combustion engine further includes a second low-pressure cylinder housing a second low-pressure piston, the second low-pressure cylinder being arranged in upstream fluid communication with the first high-pressure cylinder for providing compressed gas into the first high-pressure cylinder, and a second high-pressure cylinder housing a second high-pressure piston, the second high-pressure cylinder being arranged in downstream fluid communication with the first low-pressure cylinder for receiving compressed gas from the first low-pressure cylinder, and further arranged in upstream fluid communication with the second low-pressure cylinder for providing exhaust gas into the second low-pressure cylinder. | 2017-06-15 |
