ENVIRONMENTAL ENGINE CONTROLS UPDATE 
ANSWERING INDUSTRY NEEDS


In this issue:

  • PROGRAM DATA: RAISING ALTERNATIVE FUELS PERFORMANCE TO DIESEL LEVELS
  • NEW PRODUCT UPDATE: DIGITAL INJECTOR test data looking great for new wiz kid on the block!

PROGRAM DATA : SBIR Phase II report -Advanced Fuel Injection & Valve Train Technologies

AN ENABLER FOR ALTERNATIVE LIQUID FUELS
“This proprietary technology platform is well suited to further optimization of the engine performance”

V8 Engine Dynamometer Test Results with Alternative Fuels:
  • Controls enable Jet A fuel to match diesel performance
  • Sturman technology platform increased the engine torque by up to 7%
  • Engine cylinders were balanced within 2% or less (IMEP) variation
  • B20, B50 and B100 performance improved to meet diesel engine torque values
  • We reduced torque loss for 100% biodiesel from 9.5% to 1.6% using Sturman controls
