I have put together a 4 cylinder peugeot diesel and an 8 kw alternator.At first it was direct coupled to run at 1500 rpm but didn't have enough grunt when i struck an arc with my mig welder. I then put in a lay shaft the engine runs at 2275rpm alternator at 1500rpm. same problem engine allmost stalls under heavy load. At this speed the engine is producing max torque 70 lb ft the alt should only need 33 lb ft. pls help
The alt is what RPM you will set the engine atMost 120-240 volt are 50 HRX and run at 1800or 3600 so if it's the 3600 back end your using the wrong engineUnless you use a pulley and belt to get the correct RPMMY 8K Diesel marine ONAN direct drive 3cyc runs at 1800 Rpm If your over loading the genset than no engine will workwhat is the load your pulling as 8K is 80 amps Max single 240V or 40 amp double 120V
