Soviet generator revival (2 stroke/military)

220 Volts AC 50 Hz - this is a standart voltage, not 240 or any other. Gas engine. Oil to gas ratio 1:25.

It's certainly two-cycle gas. There's no fuel injector there is a carb. The intake and exhaust are on opposite sides of the cylinder with no valves. There is no provision to fill or drain oil in the crankcase. The thing low on the front of the exhaust side is a magneto. On the intake side is some sort of governor with a push rod to the throttle plate.

Perhaps it had specific use in the military back then?

lines are vulnerable and and there's electrocution danger

On the money thanks!

Correct 100% today had a chance to look at it well.

Here we go many more pics..
Gas 2 cycle.
if you look at side bottom of crankcase, what are those “drain like” plugs?

3000 rpm 1.5kva. Seems if so to only have been test run perhaps at production

1:25 with moder full synth oil or go less at say 1:32 or 1:40?

 

[Peandas]

Seems like the drain and fill plug are to be filled with I guess a gearbox oil, as it is seperate from the crankcase and runs governor and ignition point

Oil SAE 50 API CB 1:33 for summer- this is correct ratio.

Двигатель «2СД»​

Двигатель 2СД-М1 на мотоблоке

2СД — серия двухтактных бензиновых стационарных двигателей, унифицированных по деталям цилиндро-поршневой группы и коленчатого вала с двигателями мотоцикла «Минск». Двигатели имеют воздушное охлаждение. Выпускались Петропавловским заводом малолитражных двигателей. Основное топливо — бензин А-72, топливо допустимое Б-70 или А-76. Масло для топливной смеси MC-20 в пропорции 1:33 по объёму. Свеча зажигания экранированная А10Н с резьбой M18×1,5 или неэкранированная с резьбой M14×1,25 через переходник. Рабочий объем — 123 см3, температура эксплуатации −50 … +50 градусов, допускалось использование эфира для зимнего пуска. Угол опережения зажигания −8 градусов для низкокачественных топлив, −4 градуса для нормального. Номинальные обороты 3000 об. в мин. Мощность номинальная 0.75-1.0 квт. Имели следующие модификации:

• 2СД-М2 — модификация с измененным пусковым механизмом.

Thanks for the advice. Would a modern full synth at 1:33 harm it?

это очень полезно, особенно с точки зрения времени. спасибо, что разместили это. вы случайно не знаете, где я могу купить на него запчасти в россии, украине или европе?

2сд-м2 + youtube....and use subtitles...

On the first page....your 2nd picture...

On the plate from left to the right it is written..

1)Izključeno = dissconnected
2)Uključeno = connected
3) dont know....my father reads only Serbian letters....which are different from Russian
4)Provjerba = test (that small black button)

That additional "sparkplug" or better glow plug....is most probably the one to start that engine on a cold day....on diesel/lamp oil/acetone....

 

[Kamele0N]

1:25 with moder full synth oil or go less at say 1:32 or 1:40?

Most probably it has bronze bushings on its con rod...so stay with 1:32...

 

[Kamele0N]

4) provjerba ohmmetra = you test a scale on its Ohm-meter

Yes...looks like some kind of PTO shaft....

Put some 15w40 HDEO in there....

The oil answer is almost always 32 to 1, or 4 ounces of oil per gallon. The best quality oils are EG-D or FC-FD (FC and FD are equally good with regard to wear) . TCW-3 is not as robust and won't provide as much protection for air cooled engines.

Our two stroke oil testing showed that anything less than 32 to 1 increased wear, regardless of oil brand or choice. Although it's good to note that 50 to 1 is perfectly appropriate for low stress engines, such as 1HP outdoor power equipment.

On another note, many generators can be easily changed over to 120V and 60HZ. Just raise the RPM to 3600 AND use an appropriate, modern voltage regulator designed for a 120V recreational vehicle style generator. These can often be found for $15 or so.

Yes, with a modification like this, you won't get rated watts, due to cutting the voltage in half, but you might be surprised at just how well it will do. Raising the RPM from 3000 to 3600 will help output. A 1500 watt 220V 50HZ generator will make about 1000W at 60HZ, 120V.
