Title:
DEVICE AND METHOD FOR CONTROLLING OUTPUT POWER OF CYLINDER IN BATCHES IN INTERNAL COMBUSTION ENGINE, AND ENERGY CONSERVATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/073144
Kind Code:
A1
Abstract:
A device and method for reducing energy consumption when an internal combustion engine has a small load, comprising two or more throttle valves (1, 3), each throttle valve (1, 3) controlling some of the cylinder air intake; each throttle valve (1, 3) has behind itself an intake manifold, an air sensor (2, 4), oil nozzles (5, 6, 7, 8), an exhaust gas recirculation valve (9, 10), and a cylinder. When the internal combustion engine operates at a medium rotational speed and has a small load, some of the cylinder air intake is increased while ensuring that the total output power of the internal combustion engine meets the requirements, thereby enabling the internal combustion engine to enter an optimal working condition; the throttle valves (1, 3) of the rest of the cylinder are closed, the oil injection is stopped, and the exhaust gas recirculation valves (9, 10) are opened to the maximum, thereby keeping the movement resistance of pistons at the minimum and the temperatures of components inside of the system moderate, and preventing motor oil from being sucked into the cylinder.
