14 Liter displacement V8 YAMZ engine, on producer-gas (wood-gas)
1800 RPM irrigation pump, appr. 170 kW (would be 140 kWe / liter at 1500 RPM) * custom-sized turbocharger specifically for producer gas ** it was very difficult to achieve 40kWe / 4liter (10 kWe /liter) on a turbo 1500 RPM genset, because the turbine an compressor efficiencies are trash ~40 kW. ** Much better => easier around 170 kW range. ---- Trigger * primary trigger: 24-2 HALL type recommended with [Honeywell 1GT101 HALL sensor] * since gear-driven camshaft is good enough, second trigger is not required ---- Standard analog inputs * CLT Coolant temp * MAT Manifold Air Temp * EGT (exhaust gas temp before turbine) * MAP Manifold Air Pressure: 400 kPa absolute * TPS throttle position sensor * Wideband oxygen ---- Extra analog inputs (0-5V) * Oil temp * Oil pressure * EBP: exhaust backpressure ( before turbo, 400 kPa absolute) * externally measured startup-mixture Extra digital inputs: * Oil pressure switch * Coolant temp switch * Oil-level switch (too low) note: It's easier if we keep the number of analog inputs + digital inputs <= 7 (or max 8 with EGT). ---- Frequency input: * target RPM: 500-1800 RPM, 0-60 Hz, eg. 30 RPM /Hz * ... ---- PWM Outputs: * Throttle * Boostcontrol, WASTE GATE control * mixture-valve (PWM command to leadscrew valve controller) ---- Frequency outputs: * tach output 0-2000 ---- On/OFF outputs * "fuel valve" (fuel-pump output can be used, shuts down if engine stalls) ---- Ignition outputs * 8 power-IGBTs for passive ignition transformers Firing order ? |
