Fuel Injected EFI Cars using HHO Part 2
www.hydrowaterpower.com www.hydrowaterpower.com Others promote installation of an adaptor that will recess the oxygen sensor to make the readings less lean than what the CPU would normally receive. Be advised that it’s still possible that these modifications will not correct the problem if the vehicle continues to have long periods of idling with the HHO running. If a switch were installed onto the throttle disabling the HHO during periods when the throttle is at idle position, or if the driver were to switch off the unit manually during engine idle periods, mileage figures will probably be improved. It’s best to not have the HHO running on EFI vehicles during engine idle otherwise mileage will be negatively affected. Another potential problem with EFI vehicles concerns how the HHO is brought into the engine’s intake. If the HHO is vented into the engine via of a vacuum line, especially a vacuum line that is vented to open air, a very lean condition will be recorded at engine idle. This condition not only will affect the fuel delivery information by the CPU, but could be severe enough for the “Check Engine” light to come on. If HHO is delivered through a vacuum line care must be taken to make sure there are no vacuum leaks, otherwise turning the HHO unit off via of a switch will not correct problems with poor fuel mileage. www.hydrowaterpower.com www.hydrowaterpower.com
