(1)六缸、十二缸燃气机装置磁电机、设定点火提早角的办法(以调整机组点火提早角至40°曲轴转角为例)①盘转飞轮,至一缸处于紧缩冲程上止点位置的0刻度,再倒回40°,即,指针指示320°。此时,齿轮箱联轴器的凹槽倾斜方向肯定。

(1) Magneto of six-cylinder and twelve-cylinder gas engine, method of setting ignition advance angle (taking adjusting ignition advance angle of unit to crankshaft rotation angle of 40 degree as an example): (1) disc flywheel, 0-scale of one cylinder at the top dead-end position of compression stroke, and then back to 40 degree, that is, pointer indicating 320 degree. At this time, the groove inclination direction of gearbox coupling is certain.

②转动磁电机的驱动器,使转轴上旋转的短红刻线对准磁电机正面面板上的CCW线。此时一,磁电机驱动器的倾斜方向肯定。

(2) Turn the driver of the magneto to align the short red markings on the spindle with the CCW lines on the front panel of the magneto. At this time, the tilt direction of the magneto driver is certain.

③装上磁电机,此时,发起机点火提早角近似为40°。

(3) When the magneto is installed, the ignition advance angle of the initiator is approximately 40 degrees.

留意:装置磁电机时应确保其驱动器与齿轮箱的联轴器啮合到位。

Note: When installing a magneto, ensure that its driver engages with the coupling of the gearbox in place.

④用拖动法检查点火提早角的实践值,调整至需求的数值。

(4) The practical value of ignition advance angle is checked by dragging method and adjusted to the required value.

⑤十二缸燃气机磁电机调整位置到极限状况需求调整锥齿轮(倒齿)。办法为:

Adjusting the position of 12-cylinder gas engine magneto to the limit condition requires adjusting bevel gears (inverted teeth). The methods are as follows:

a.松开齿轮箱侧面察看盖上的紧固螺钉,取下察看盖。

A. Loosen the fastening screw on the side of the gear box and take off the cover.

b.松开衔接盘与齿轮箱固定的6个紧固螺钉,将小锥齿轮连同传动轴一同抽出,使两个锥齿轮脱离啮合。

B. Loosen the six fastening screws fixed by the connecting disc and the gearbox, and pull out the small bevel gears together with the transmission shaft, so that the two bevel gears are separated from meshing.

c.转动小锥齿轮(每倒一个齿点火提早角改动约12°),使联轴器凹槽方向与磁电机衔接盘的倾斜方向分歧。

C. Rotating the bevel gear (the ignition advance angle of each inverted tooth is changed about 12 degrees), the direction of the coupling groove is different from the inclination direction of the magneto connecting plate.

d.将小锥齿轮装回原处,使两个锥齿轮重新啮合,盖好察看盖。

D. Install the small bevel gear back to its original position so that the two bevel gears mesh again and cover the inspection cover.

e.装上磁电机,复查点火时间。

E. Install the magneto and check the ignition time.

(2)四缸发起机装置磁电机、设定点火提早角的办法(以调整点火提早角至32°为例)。

(2) The method of setting the ignition advance angle by setting the magneto of the four-cylinder starter (taking adjusting the ignition advance angle to 32 degrees as an example).

①工作原理

Principle of operation

4缸燃气发起机(4-190)点火系统由磁块、感应线圈、磁电机、点前线圈、火花塞构成。点火次第为1-2-4-3。

The ignition system of 4-cylinder gas engine (4-190) consists of magnetic block, induction coil, magneto, pre-point coil and spark plug. Ignition order is 1-2-4-3.

飞轮上分别在160°、340°位置处镶嵌有两个磁块。在飞轮旁装置有内侧、外侧两个感应线圈。外侧感应线圈衔接1、4缸,内侧感应线圈衔接2、3缸。

There are two magnets embedded in the flywheel at 160 and 340. There are two induction coils beside the flywheel. The outer induction coil connects 1 and 4 cylinders, and the inner induction coil connects 2 and 3 cylinders.

发起机工作时,飞轮上的磁块每当经过感应线圈时,获取一个信号,并把此信号传送给磁电机。磁电机按此信号提供的次第发出点火电能,经过点前线圈变压,由火花塞点火。

Whenever the magnetic block on the flywheel passes through the induction coil, it obtains a signal and transmits it to the magneto when the engine is working. According to this signal, the magneto generates ignition energy in the next order, which is ignited by the spark plug through the pre-point coil voltage change.

当外侧感应线圈次获取磁块信号时,1缸点火,旋转180度后,内侧感应线圈获取磁块信号,2缸点火。飞轮再旋转180度后,外侧点前线圈获取磁块信号,4缸点火,再旋转180度后,内侧感应线圈获取信号,3缸点火。

When the external induction coil acquires the signal of the magnetic block for the first time, one cylinder ignites, after 180 degrees rotation, the inner induction coil acquires the signal of the magnetic block, and two cylinders ignite. After the flywheel rotates 180 degrees again, the front coil of the outer point obtains the signal of the magnetic block, four cylinders ignite, then rotate 180 degrees, the inner induction coil obtains the signal, and three cylinders ignite.

②设定办法

(2) Setting methods

a.盘转飞轮,至一缸处于紧缩冲程上止点位置的0刻度,再倒回32°,即指针指示328°。

A. Turn the flywheel to a cylinder at the zero-scale of the top dead-end position of the compact stroke, then turn back to 32 degrees, i.e. the pointer indicates 328 degrees.

b.转动磁电机衔接塑料盘,使倾斜方向与法兰内转盘的倾斜方向分歧,将磁电机装好。

B. Rotate the magneto to connect the plastic disc, so that the tilt direction is different from the tilt direction of the rotating disc in the flange, and install the magneto.

c.挪动两个感应线圈,对准飞轮上的磁块,并使两个感应线圈处于同心直线上,固定感应线圈。此时,发起机点火提早角近似为32°。

C. Move two induction coils, align the magnetic blocks on the flywheel, and make the two induction coils in a concentric straight line, fix the induction coils. At this time, the ignition advance angle of the engine is approximately 32 degrees.

d.检查点火提早角的实践值,并调整至需求的数值。。

D. Check the practical value of ignition advance angle and adjust it to the required value.
