injection pulse meaning in English

注入脉冲

The start of pulse injection , injection - pulse numbers , injection period of each pulse and the dwell time between injection pulses are controlled by a fircri injector system
它通过电控高压共轨喷油器控制燃油多次喷射，从而控制燃油预混合气的形成和着火时刻。
The last or main injection pulse is set around tdc . when the diesel spray impinging on the combustion wall , the bump around the combustion chamber wall can strip off the wall jet and form a secondary spray in combustion chamber , so the fuel and air can mix well and homogenous
在主喷射时刻，利用燃烧室壁面的bump迅速剥离壁面射流，在空间形成二次射流，二次射流进入燃烧室空间后，再一次与空气混合，形成相对均匀的稀混合气。
A mathematic model initial injection pulse - width is set up according to the quality ’ s continuousness and the energy conservation law . we can get the initial injection pulse - width map graph of the motorcycle ’ s efi system , and the results showed well consistent with the stand experimental results which had applied to the domestic 125ml motorcycle gasoline engine
根据气体状态方程和能量守恒定律分析建立了基本喷油脉宽的数学模型,并运用在国产125ml摩托车汽油发动机上,仿真得出此发动机电控汽油喷射系统的初始喷油map图。
