It is an interesting project of a very powerful, reed valve engine. It uses as base engine the robust and reliable Zenoah 32cc engine with a completely new billet machined crankcase and a new crankshaft with longer stroke. The Zenoah 32cc is an engine with which we have a lot of experience, it is an engine with a very good quality and very tested. The engine is made to work at high revs. To reduce the engine RPM a little, this version has a crankshaft with a higher stroke. This makes a total displacement of 34cc.
A Löweheiser Electronic Injection with a 14mm body has been mounted. We have done some tests in which we get extremely low consumption with gasoline. In addition tests have been done with heavy fuel, in our case with Jet-A1 but it will work the same with JP-5 and JP-8.
The engine features:
- Base Zenoah 32cc engine with custom billet crankcase
- Stroker crankshaft with total stroke of 30mm (+2mm)
- Custom induction system with reed valve
- Custom throttle body with integrated mini size servo.
- Lightweight Löweheiser ECU
- Compact tuned exhaust (optional)
- Tested with heavy fuel (Jet-A1)
- Cold start and cold operation capability to -25°C
