Cold-Start Ignition Engines are equipped with dual-fuel system, fuel feed is switched from diesel to test fuel during starting sequence

Engine Loading – Power, Durability, Efficiency Engines are loaded by dumping current from generator into resistor bank. Increased resistance = increased power output Peterson Test leads to accelerated engine wear

Emissions Testing Real-Time analysis of CO, CO 2 , SOx, NOx, and Combustibles
