Case Studies
The AquaTune Water Injection System has helped many owners pass previously failed DEQ emissions tests. In an effort to show you how our system can help your car run "clean and mean" we've presented some actual emission before and after reports. Here's a brief break-down of the terminology used in the studies and reports:
- CO's: using too much fuel
- HC's: hydrocarbons, running poorly or misfiring or too much carbon
- NOx: too much heat in combustion chamber creating a noxious gas that is harmful to the environment
1977 Cadillac
Fixed emissions problem
This vehicle didn't pass because the engine was not running efficiently enough, it was burning too much fuel. All that was done was to install the water injection system. Now note the consequent reduction in both HC's and CO's.

After
1994 Toyota Tercel
Emissions, and excess oil burning eliminated
This test had to be aborted because the vehicle was burning oil excessively past the engine rings. After the water injection system was installed the vehicle was allowed run for two hours and the smoke emissions were cleared up and the rings cleaned up.

After
1990 Dodge Caravan
Fixed emissions problem
Please note the emissions on NOx and CO's. This customer had been told that he needed to replace the CAT converter and a major tune-up. Estimated amount for these repairs was $800. The water injection system was installed and the vehicle passed the emissions test easily.

After
1990 Dodge Voyager
Fixed emissions problem
Different vehicle but, essentially the same problem as the Dodge Caravan in that this vehicle was failing on the NOx. The water injection system was installed, the vehicle passed the emissions test and the customer saved approximately $600 in repairs.

After
1997 BMW, M3 3.2L
Fixed emissions problem
Before, NOX reading as it was certainly borderline from passing. The After reading shows the dramatic drop in the NOX.
