Diesel-Blend – LPG/CNG

 

Diesel-Blend Dual Fuel Demonstration VehicleAnother cost saving option for fleet operators and high mileage diesel users is to run their vehicles on a cheaper fuel blend.

The Select-A-Map ECU was also developed to enable common rail diesel engines to run on a blend of at least 2 fuels, the most common being Liquid Propane Gas (LPG) or Compressed Natural Gas (CNG). It is compatible with most existing makes of LPG or CNG liquid and vapour systems that are designed to operate with multipoint petrol injection vehicles when used in diesel blend applications.

LPG substitution ratios of up to 40% are normal whilst using CNG ratios of above 50% can be substituted on much lower price fuel giving savings of typically between 10-25%.

The SELECT-A-MAP Diesel Blend ECU has many features and benefits not previously available including a choice of maps to suit the type of secondary fuel being used (LPG or CNG) and different operator requirements. Precise control of each fuel via two separate maps allows ethe perfect mixture to be achieved without any increase or decrease in overall engine power.

The Select-A-Map system acts as a universal interface when used with an LPG or CNG gas system, providing the gas system with simulated conventional petrol fuel injection signals that enable any standard gas system to be used in a dual-fuel / diesel-blend application. This unique approach means that the Select-A-Map can be used with virtually any gas system to create a diesel-blend system. Manufacturers of compatible gas systems include (but are not limited to) Prins, Vialle, BRC, OMVL, Zavoli, Eurogas, Bi-Gas, Romano, Tartarini, Landi Renzo, KME, Stefanelli, Necam, Koltech, LPG Tech, Altesa, Stag, E-Gas, Lima, Impco, Mercury, AG, GSPK, XL-R8, Star Gas, Leonardo, Emma-Gas, Bedini, Lovato, Calor, Calorgas, Autogas, Icom, Valtek, Majic, AEB, Stako, GWZM and Pharos.
