Engine cycle ignition energy-saving device and engine and cycle ignition method thereof

Abstract

The invention discloses an engine circulating ignition energy saving device. The engine circulating ignition energy saving device comprises a nozzle, a heat insulation cavity and an ignition valve. The nozzle is arranged above the combustion chamber and communicates with the communication chamber. The heat insulation cavity communicates with the nozzle through a channel and is used for storing high-temperature and high-pressure gas generated by the combustion chamber. The ignition valve is arranged in the channel and used for controlling opening and closing of the channel. When the ignition valve is opened, the high-temperature and high-pressure gas enters the combustion chamber and is used for igniting mixed gas in the combustion chamber. An engine circulating ignition device is adopted, the high-temperature and high-pressure gas generated through combustion in the combustion chamber can be stored, and when ignition is needed for an air cylinder, the high-temperature and high-pressure gas can be released to achieve space ignition. Meanwhile, the ignition nozzle is designed into the heat insulation cavity with the adjustable volume, a whole engine is equivalent to a changeable compression ratio engine, and the comprehensive performance of the engine is improved. The invention further provides the engine.

Description

technical field [0001] The invention relates to the field of engines, in particular to an energy-saving device that utilizes high-temperature and high-pressure gas to realize engine cycle ignition. Background technique [0002] The engine's combustion chamber is used to convert the chemical energy of the fuel into mechanical energy. The ignition of fuel in the combustion chamber of a gasoline engine depends on several factors: the temperature of the combustible mixture, the type of igniter, the ignition energy, the fuel-air ratio, the input point of ignition energy and the mixing state of the combustible mixture, etc. The combustion chamber of a gasoline engine needs an igniter to Breakdown the combustible mixture to generate electric sparks to trigger the combustion process. At present, gasoline engines generally use spark plug igniters. The ignition system generates a high-voltage pulse that is applied to the spark plug, and a transient high-voltage electric field is gener...
