摘要: | 本发明公开了一种发动机判缸方法及系统以及汽车发动机,属于汽车发动机启动技术领域;方法包括:步骤S1,对汽车发动机中的一个气缸执行少喷油操作,并记录相应的喷油时刻;步骤S2,判断气缸内是否发生预设的燃烧欠缺现象,并记录相应的欠缺时刻;步骤S3,判断欠缺时刻与喷油时刻之间的时间距离是否小于一预设阈值,并在时间距离小于预设阈值时确认汽车发动机的相位错误;步骤S4,对汽车发动机的相位进行变更,随后退出。上述技术方案的有益效果是:解决现有的汽车发动机在判决其相位是否正确时所采用的硬件判决方式过于复杂的问题,并且降低发动机判缸的成本。 | ||
摘要(英文): | The invention relates to a kind of engine cylinder detection method and system of the automobile engine and, which belongs to the technical field of automobile engine is started; the method includes : the step S1, to the automobile engine the implementation of one of the cylinders in operation few blows, and record the corresponding injection time; step S2, judged whether there is in the cylinder the lack of combustion of the pre-phenomenon, and record the corresponding lack of time; step S3, the lack of time and the judging time distance between the fuel injection time is less than a preset threshold value, and the preset threshold is less than the distance between the time that the phase errors of the automobile engine; step S4, the phase of the change of the engine, then exit. The above-mentioned technical scheme has the advantages of : solving the existing automobile engine the judgment whether the phase of the correct hardware judgement way the problem of too complex, and reduce the cost of the cylinder detection of the engine. |
