Flash frequency was changed when engine speed changed. The closer engine speed to the switch speed set, the faster flash frequency is .The lower engine speed is than switch speed set, the slower flash frequency is.

14：发动机燃气调试介绍

The introduction of engine gas adjustment

①影响发动机运行状况的参数很多，调试者应先查看原车有

无故障码，如有故障码应及时清除；

There are many parameters of engine running condition affected, adjuster should check whether the original vehicle has diagnostic trouble code, if it has, adjuster should clear it in time.

②检查机械部分的装配，应按照改装工艺规范施工，保证系

统的良好匹配性。

Check the assembly of mechanical parts and construction standard in according to technology of modify, ensuring the good match with system.

③改装工艺保证的前提下，软件上调试的主要参数就是修正

比例和修正偏移了，推荐调试步骤如下：

Ensuring the technology of modify, the main parameter corrected by the software is constant percentage and offset injection time. The steps recommended as follows:

(1)：首先将修正比例设为115%，修正偏移设为0.0ms；

At first the constant percentage set as 115% and the offset injection time set as 0.0ms.

(2)：怠速调试：启动发动机，记录在燃油模式的燃油喷射时间，然后将车切换到燃气模式观察燃气模式下的燃油喷射时间，并观察汽车怠速的运行情况，若怠速抖动且燃油喷射时间比油模式大得多，则表明混合气偏稀，应该加大偏移修正；若怠数抖动且燃油喷射时间比油模式小得多，表明混合气偏浓，应该减小修正比例，直到发动机比较稳定。

Trim at idle: Start the engine and record the petrol injection time in the petrol mode, then switching to the gas mode, watching the gas injection time in the gas mode and the running condition at idle. If vibrating at idle and petrol injection time is more than petrol mode’s, it shows the gas mixed is thinner and the offset injection time set should increase. If vibrating at idle and petrol injection time is less than petrol mode’s, it shows the gas mixed is thicker and the offset injection time set should reduce until the engine is stable.

(3)：高速调试：将发动机启动，记录发动机在燃油模式时，发动机转速在3000转/分的燃油喷射时间，然后将车切换到燃气模式观察在燃气模式下的燃油喷射时间和发动机的高速运行情况，若高速动力不足且燃油喷射时间比油模式大得多，则表明混合气偏稀，应该加大修正比例；若高速动力发梗且燃油喷射时间比油模式小得多，表明混合气偏浓，应该减小修正比例，直到发动机比较稳定。

Trim at high speed: Start the engine and record the petrol injection time in the petrol mode when the rotational speed is 300r/m, then switching to the gas mode, watching the gas injection time in the gas mode and the running condition at high speed. If the power is shortage at the high speed and the petrol injection time is more than petrol mode’s, it shows the gas mixed is thinner and the constant percentage set should increase. If the power is excessive and the petrol injection time is less than petrol

mode’s, it shows the gas mixed is thicker and the constant percentage set should reduce until the engine is stable.

(4)：重复步骤⑵、⑶，直到发动机在整个模拟运行中都比较好。

Repeat the step(2)、(3) until the engine runs better in the entire simulation.

(5)：进行试车操作，并微微调节以上设定的参数，力求达到较好的动力性和经济性。

Has a test run and adjust the parameters set above a little to reach the better power and economy.

15：最小脉宽为燃气喷轨的最小喷射宽度。

Minimal impulse is the minimal injection width.

16：MAP修正

MAP corrector

17：标定表:当发动机过排放测试时进行微调节的表格，在大多数要求动力性和经济性的调试中，可以关掉此项，降低调试的复杂程度。

Calibrate: The table adjusted weakly of the emission test. In the most of trims which need power and economy, cancel the item to reduce the complexity of the trim.

18：喷轨类型决定了ECU的对喷轨的驱动参数，此项的设置应谨慎，以免喷轨被错误的驱动而导致ECU或喷轨损坏。

The type of injections decides the driver parameter of injection. To set this item should be careful to avoid ECU and injection for injection driver damaged by mistake.

19：L0、L1、L2、L3、L4为在燃气模式或强制燃气模式下
