It’s myth-busting time and no, unfortunately, I don’t mean with Adam and Jamie but it might be just as scientific. Strap in.
Your Integrel alternator is so powerful it will put too much load on my engine and either damage it or cause me to lose power whilst motoring!
Our Integrel alternator can create between 3kW and 9.5kW of power dependent on the RPM of the engine and the “spare power” available at any given point in the engine’s power curve.
But what do we mean by “spare power”?
Through research, we have discovered a gap between the power required to rotate the propeller(prop load) and the optimum (most fuel-efficient) engine power, at any given RPM. We utilise this gap in power by adding a variable electrical load to the engine to bring the total load (propulsion and generation) closer to the optimum engine load line.
What makes it variable? Aren’t alternators set to one power output?
The Integrel alternator/generator is kept at optimal efficiency without overloading the engine by our innovative Integrel Smart Controller. This Smart Controller detects the engines RPM and prop load, and then uses this data to vary the Integrel generator’s output amps. It also recalculates engine power available for generation every 10mS, allowing both propulsion and generation to be delivered at close to optimum engine efficiency across most of the engine rev range.
Won’t an extra load damage my engine?
Because of the high power output of the Integrel generator, several
measures are taken to protect the engine and to prioritise propulsion:
• No power is generated until the engine temperature is above 30C.
• Power ramp-up is gradual and slows further as any control limit is
• The generator output is set to zero when a gear change or any rapid
transient is detected; power ramp-up only recommences when the system
is satisfied that the engine is back in a steady state.
• Crankshaft side loads and load angles are kept within permitted limits.
• Crankshaft torsional vibration is managed with an automotive spring
In Conclusion; no power is lost whilst motoring and no additional load is added to the engine. Myth busted.
