ITO ANG NUVITRON! Drive cycle test results

[pyramid00]

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).

If you think that dyno test is NOTHING compared to a drive cycle test, why don't you just do the dyno testing as well. It should pass in flying colors in the dyno test wherein an X amount of fuel should yield Y amount of HP before and after. The only reason I can see why you don't wanna do the dyno test is that your product will just fail with flying colors.

i'm sorry, that's not what i meant. ok, take 2. a dyno test cant be compared with a drive cycle test because a dc test is too taxing for an old engine. in fact, i requested to test the devices on any jeep plying around UP but the director refused saying that the jeep may not be able to withstand the stress that an old engine will undergo.

It is our intention to test the device at Speedlab in the future and then again an emission test at VRTL so that the series of testing will be complete; economy test at vrtl, dyno test at speedlab and emission test at vrtl. I've read in a thread that niky mentioned a P5k/hr dyno test at speedlab. Maybe, the dyno test will be on a izusu crosswind.

btw, testing will not be done on a euro 4 engine esp a obd2 compliant engine. the upstream and downstream 02 sensors will just signal the ecu to dump more fuel via the injectors. of course, this conditions will be 'cured' by efi enhancers for gasoline engines and map enhancers for diesel engines. Medyo madugo ang activiting ito. Gagastos ka sa fuel savers + sa mga enhancers. Hindi ko alam kung available ang mga ito dito. You best bet for tuning ecu controlled/obd2 compliant engines? Engine tuning with chips.

Anyway, we installed the devices on a toyota innova diesel and the owner said that he is getting 14k/l on the highway. The bad part is that he does not know the baseline.

[niky]

14 km/l on the highway?

I typically get between 12 - 16 on the highway when I drive the company Innova (and, mind you, I've never hypermiled it... I believe 20 is entirely possible). 14 is neither terrible nor extraordinary.

-

Also, 90% savings at 80 km/h on the Tamaraw? So... was it doing 1 km/l beforehand and 10 km/l after, or was it doing 10 km/l beforehand and 100 km/l after? Just curious.

Nice one, Niky but we're just wasting time with this thread.

I get 15km/l fron my Innova on highway. All stock.

They are trying to phase out older vehicles for the very reason why fuel management, engine horsepower and Torque have been greatly improved on newer models. Manufacturers have seen the reality of these issues that's why they included these improvements and continue to develop more efficient vehicles. The main issue here is the lack of proper vehicle maintenance that leads to problems like pollution, accidents, etc. Even if you give them fuel saving devices if they don't maintain their vehicles religiously then what's the point of saving an old clunker altogether when the truth is those jeepney and bus operators don't give a hoot about their commuting patrons be it comfort, convenience nor life itself as evidenced by the series of accidents that have been caused by poor vehicle condition and the lack of their driver's concern for safety. At todays traffic conditions fuel saving devices don't do much justice as witnessed by a lot of our tsikoteers for the very simple reason that these need to operate at constant or efficient load before they can do their job. Who can run efficiently on a jerky 10-30kph traffic pace plus the fact that it takes forever to get from point A to point B w/c in my case from Marikina on a good day takes 2.5hrs and probably 3-3.5hrs on a worst day per way to Makati. Worst I find myself driving or in my car at least 5-7 hrs a day so not much work gets done so I am not entirely saving anything if I am not productive. Giving those traffic starters fuel savers won't improve our lives nor the air around us. To the TS, if you want to help improve our lives come up with something that will encourage or change the way our commuting public look at the transport industry like what the E-vehicles or their contemporaries have done. Just my two cents!

Ilocano ata si TS.
Nakita ko yung word na "pagsayaatan" sa reply nya. Meaning.....ikabubuti.

Cool lang tayo mga erap. Baka ma lock itong thread.

[Walter]

It should be locked.

[Ry_Tower]

It should be locked.

I second the motion. These kind of threads should have no place in a forum. This is not a advertisement. Bayad na lang sila sa tsiot for a formal ads. Yun ang tama.

[yebo]

And don't just lock the thread. BAN THE TS! Kung pwede nga padalhan ng virus yang inutil na yan e! Virus na tunay ha, hindi yung sa computer!

lets talk about digital:

5 - square waves - fast rise,fast decay, 50% duty cycle, (e.g. 10 hz, there are 10 pos and 10 neg, we utilize the pos pulses and the neg pulses are damped by a diode) alam niyo naman ito, i'm sure. what's the fuss about the digital term?

ts, ikabit mo nalng sa katawan mo yang device mo at lock na itong thread ng sa gayon "maka-save" kami ng time sa pagbasa sa kalokohan mo.

“THE BEST WITNESS IS THE EVIDENCE; the vrtl drive cycle test results said it all.”

The DC test comp said that an engine was tested and it exhibits a fuel savings of x % * 40, 60 and 80kph. The bottom line is that the devices save fuel.

This DC test result is posted as a public doc for the sake of record. Some ts won’t accept it. They have their own reasons. To those who believe it, salamat po. Hindi ako ang paniwalaan niyo but the testing results..

Sa emission lang yan, iba pa rin usapan sa hp, torque at fuel consumption. Gamitin mo sir utak minsan. Paano mo dadayain ang dyno para sa torque, hp at fc? Yung sa emission madali lang, nilagyan lang ng accelerometer sasakyan, at detected na kungmay actual motion sasakyan. Sir, wag mo gawin tanga tao dito.

[pyramid00]

korek kayo,sir, vvti, i was referring about the emission tests of a vehicle na naka kabit sa dynamometer during emission and fuel consumption test during the drive cycle test. case in point, the vw cheating device. i was not referring about the dyno test na gaya sa speedlab.
