Warsaw is capital city of Poland, of course we were part of the Eastern Bloc, but not of the Soviet Union. In addition, WFM motorcycles with engines based on RT125 were produced in Warsaw. SHL motorcycles were produced in the city of Kielce. We also had another plant producing WSK motorcycles in the city of Mielec, the engines of which were also based on the RT125 design. It is estimated that about 3 million motorcycles were produced based on the RT125 engine in Poland. In 1962, the SHL M11 production license was sold to India. Motorcycles were produced under the Rajdoot brand until 2005. Over 4 million of these motorcycles were produced in India.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2164874096778415414.post-19213417705333040502022-01-08T14:47:30.095-07:002022-01-08T14:47:30.095-07:00The best on this subject that I have found.

The output potential from ...I agree with anonymous. The output potential from a supercharged opposed piston engine with a 15-25 degree phase lag is very high. Add in direct injection to prevent any possible overscavenging, and its fuel conunption should be very good for its power output. Now, if only it were possible to reduce oil burning caused by oil leaking past the cylinder ports, this would be a real winner. I understand that Achates power is working on this problem. I really hope they are successful.Nicodemushttps://www.blogger.com/profile/09127272986757650550noreply@blogger.comtag:blogger.com,1999:blog-2164874096778415414.post-3733379630751511272015-07-31T16:13:34.589-06:002015-07-31T16:13:34.589-06:00I believe there is a future for 2 stroke superchar...I believe there is a future for 2 stroke supercharged engines when using direct fuel injection.With supercharging the intake mixture can bypass the crankcase. The lubrication stays in the crankcase while the supercharged air flushes the cylinder, afterburning exhaust gases and with fuel injection it is possible to adjust precise amounts of fuel at the right moment, i,e. before pressure in the cylinder requires expensive high pressure injection pumps.High power to weight ratios are possible at lower cost than with a 4 stroke engine.
