On 8/8/2010, chocokorn asked, ‘Tutuo ba ang nuvitron’?

More than 4 years later, we are presenting the nuvitron, which was ‘fondly’called nuvi-nuvi (I love this name). ‘Any device without a dyno test is BS’. The dyno test is nothing compared to a drive cycle test. Our test vehicle was an 18yo Toyota FX which could hardly cope-up with the tremendous stress that it had been subjected. No old engine should undergo the tremendous load that a test vehicle is subjected to. I consider the drive cycle test an engine torture test. One thing I learned about the test; the engine should be 5yo or whereabouts, e.g., an Isuzu ’06 Crosswind’ diesel.

A drive cycle test is the only test recognized by governments all over the world as proof that a particular car/fuel saving device has the emissions and fuel consumption that the maker claims. The three standards are US EPA, European and Japanese drive cycles.

The drive cycle route is an urban route with its acceleration/deceleration, idle condition and then the accelerating/decelerating, idle, etc. It’s like traversing EDSA, only much difficult. That is why the 18yo FX could only muster a 4.8% savings.

However, on the constant speed test, the vehicle showed an almost unbelievable result. If the car is cruising at 40kph, the savings is 24%, at 60kph – 68% savings and at 80kph – 90%! Average savings could be 30-40% or more. These shows that if installed on a genset, fuel savings could be substantial.

The Toyota FX can now be called a super fx due to it’s super economy.The concerns of a motorist is fuel economy, power increase and emissions, in that order.

The EPA has tested 104 fuel-saving devices for the last 20 years and found 7 that had slightly improved fuel economy (6% max). EPA drive cycle test mode: FTP (for emissions, HFET (for fuel economy).
