AquaTune Emissions 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 four 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
1. 1977 Cadillac
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. (click your Back button to return from

2.1994 Toyota Tercel
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. (click your Back

3. 1990 Dodge Caravan
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. (click

4. 1990 Plymouth Voyager
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. (click your Back

5. 1997 BMW, M3, 3.2L
Before, NOX reading as it was certainly borderline from passing. The After reading shows the dramatic drop in the NOX.. (click your Back
