Baytech's MPFI System

The CNG and propane engines incorporate Baytech's sequential Multi-Point Fuel Injection technology for gaseous fuels. Baytech's engine calibration software optimizes closed-loop fuel control, spark advance and other engine parameters to achieve high performance and low emissions. Engine diagnostics functions are accessed through the vehicle's diagnostic port with the same scanner tools used for gasoline diagnostics.
