Context

Dynacert, based at 101-501 Alliance Ave., Toronto, Ontario, Canada, M6N 2J1 , mandated FPInnovations  PIT Group to conduct testing to evaluate the impact on fuel consumption and emissions of  the   HydraGen™ technology. This testing program was based respectively on the TMC Fuel Consumption Test Procedure – Type II, RP 1102A (TMC 2016a), and CFR (Code of Federal Regulation), Title 40 Part 1065, Engine Testing Procedures, Part 1065 - Subpart J PEMS Testing (CFR 2008).

 

This report presents the tests of contract 942 -02 - Addendum 3, as well as the first phase of the testing for contract 942-02, which was originally presented in Contract Report 942-02 (Surcel 2017).

Technology

HydraGen™ technology is designed for on-road applications with Class 6 - 8 vehicles. According to the manufacturer, HydraGen™ is a portable, safe and reliable aftermarket unit that produces hydrogen and oxygen on demand, from the electrolysis of distilled water. The addition of hydrogen and oxygen gases through the air intake would improve the combustion resulting in a more complete fuel burn which would deliver increased fuel economy, increased torque, lower emissions, and extend engine oil life. The system runs directly from the vehicles power system providing for high electrical efficiency and shuts off when the truck key is off.

 

Methodology

Test site

The tests were performed at the Transport Canada Motor Vehicle Test Centre located at 100 rue du Landais, Blainville (QC), Canada, J7C 5C9, which is presently operated by PMG Technologies (Figure 1).

 

Figure 1. Test site with radar checkpoints and weather station positions.

 

The fuel consumption tests were conducted on the BRAVO high-speed test track, a high-banked, parabolic oval, with the length of 6.66 km (4.15 miles). The emission measurements were performed on the ALPHA low-speed test track, a parabolic oval with the length of 6.88 km (4.28 miles).

Fuel consumption test procedure

The test procedure was based on TMC Fuel Consumption Test Procedure – Type II, RP 1102A (TMC 2016). The tests were conducted in test conditions according to this recommended practice, which aims to obtain results that can be considered representative of actual service conditions: this applies to load, weather, wind, etc.

 

The fuel consumption tests were conducted on the BRAVO high-speed test track. The length of a test run was 15 laps (100 km), with departure and arrival at the same position along the track.

According to the TMC Fuel Consumption Test Procedure – Type II, RP 1102A (TMC 2016), the test compared the fuel consumption of a test vehicle operating under two conditions versus an unmodified control vehicle. Fuel consumption was accurately measured by weighing portable tanks before and after each run. The repeatability of the scale measurements was periodically checked during the tests using  a set calibration weight. Figure 4 shows the installation of the portable tanks.

 

Figure 4. Installation of the portable fuel tanks.

 

Control and test vehicles had the same general configuration and were coupled to the same semi-trailers for the baseline and test segments. The vehicle weights remained the same throughout the entire test segment. The vehicles were in good working condition, with all settings adjusted to the manufacturer's specifications.

 

The test consisted of a baseline segment (using non-modified vehicles) followed by two test segments (the technology being tested, the HydraGen™, was used on the test vehicles while the control vehicle stayed in its original state). For all segments, the representative results were the ratio between the average fuel

 

consumed by the test vehicles and the average fuel consumed by the control vehicles (the T/C ratio). Results were expressed with a confidence interval of 95%, which was determined from the variation in the measured fuel consumption data relative to the nominal value and number of data values obtained. The fuel savings (F_S) and fuel improvement (F_I) were determined by analyzing the measured fuel data and reflect the changes resulting from the modification being tested on the test vehicle. These nominal values consisted of the percentage difference between the baseline segment ratio (T/C)_b and the test segment ratio (T/C)_t:

Driving procedure

Each day, prior to testing, all vehicles were warmed up for the same amount of time (minimum one hour) at the test speed.

The driver’s influence on the results was practically eliminated by conducting the tests on a closed circuit and by strictly controlling the driving cycle as follows:

Ÿ  A fixed idling time was used.

Ÿ  Drivers started with maximum acceleration.

Ÿ  A cruising speed of 105 km/h (65 mph) was set.

Ÿ  Drivers steered as close as possible to the painted line at the right side of the track, without touching it.

Ÿ  Drivers maintained a constant driving speed using the cruise control.

Ÿ  After the established test duration was complete, drivers stopped using the cruise control at the designated point.

Ÿ  During deceleration, drivers used only the service brakes and did not accelerate.

Ÿ  Once at the finish point, the trucks idled before the engines were turned off. All the vehicles in a test run idled for the same duration during the run.

The time interval between two consecutive trucks remained the same in order to avoid the effects of turbulence caused by other trucks and to prevent multiple trucks from being at the same place and time on the track. The driving cycle was controlled with two radars (Figure 1). A radar speed sign displayed the speed of oncoming vehicles using highly visible LEDs, and was checked by the test drivers at every lap. The other device was a radar gun, operated by the test personnel, and placed on the opposite side of the track. Drivers received instructions by two-way radio, to ensure that the speed of the vehicles and the distance between the vehicles on the track remained constant. The duration of the runs was also checked. The vehicles were also instrumented with global positioning system (GPS) units, which were used for checking vehicle speed and distance.

 

Emissions measurement procedure

Dynacert requested emissions measurements, which were performed on the test tractor C6 (2243) using the Horiba OBS-2200 portable emission measuring system (Figure 5), based on CFR (Code of Federal Regulation), Title 40 Part 1065, Engine Testing Procedures, Part 1065 - Subpart J PEMS Testing (CFR 2008).

The emission measurements were performed on the ALPHA low-speed test track. The length of a test run was six laps (41.3 km), with departure and arrival at the same position along the track.

The tests can be characterized by the following:

-          Two test segments: baseline segment (the test vehicle was not using the HydraGen™ technology) followed by a final test segment (the test vehicle using the HydraGen™ technology).

-          Each test segment consisted of one warm-up run followed by three valid measurement runs;

-          The runs were conducted at a constant speed of 80 km/h, with a standard acceleration and braking protocol;

-          Standard emission test: measurement of carbon monoxide (CO), carbon dioxide (CO₂), mono- nitrogen oxides (NO_x), and total hydrocarbons (THC), in g/km.

 

For the purpose of the track emission tests, the test tractor was coupled with the Taylor RS-125K Towing Dynamometer for both baseline and final emission measurement tests, which assured controlled road load and also provided the electric power for the Horiba OBS-2200.

Discussion

Road tests and track tests are subject to variations in conditions between runs, and controlling or accounting for these variables as much as possible is an important part of ensuring accurate results. Air density varies with temperature, relative humidity and barometric pressure, and changes in air density affect aerodynamic resistance. It has been proven that the air density can be computed from measurements of ambient temperatures, humidity, barometric pressure, and wind speeds and directions (Surcel et al. 2008). These parameters were measured at the test site (Figure 8) and these data were verified using climate data from the Mirabel weather station, located 12 km from the test  site (Environment Canada). Figure 9 presents the variation in air density during the testing. The maximum differences in air density between the baseline segment and the first and second test segments during the tests was 0.076 kg/m³ (6.14% variation), and respectively 0.013 kg/m³ (1.06% variation).

 

Figure 8. Measurement of environmental conditions at the test site.

 

The test results may also be higher or lower than average conditions depending on the wind velocity and direction, for aerodynamic device testing in particular. The elevation height for the wind measurement   was 19.36 feet (5.90 m). The wind speed data was corrected to the elevation of 10 feet (3.05 m), using the scale factor of 0.9099. As shown in Appendix A and Figure 10, Figure 11 and Figure 12, the mean wind speed and the maximum wind gust speed observed during the tests were within the limit of 40.2 km/h (25 mph), and respectively 48.3 km/h (30 mph) (TMC 2016a.) However, using a closed-loop parabolic oval (shape of the test track) minimizes the effects of wind yaw angle.

The only possibility for minimizing the influence of varying ambient conditions on test results is to use unchanged control and test vehicles (with the exception of the modification being tested on the test vehicle), with the assumption that both vehicles will be equally affected by these variations. For this purpose, the test and control vehicles were of the same general configuration and confirmed to be in proper operating condition prior to and during the tests. The trailers were matched to each test and the control vehicles remained matched with their respective tractors throughout the entire series of tests. The vehicles in a pair had similar odometer readings (i.e. at the beginning of test segment 153 973 km for the test tractor and 151 349 km for the control tractor).

 

The temperature of the fuel in the tank was randomly checked during the tests and never exceeded 48°C (118 °F); the maximum temperature value suggested by the practice is 71 °C (160 °F) (TMC 2016a). Fuel temperature was controlled given that the portable tanks used for fuel consumption measurements have   a large capacity (144 liters, 38 US gallons), the test run duration was short (1 hour) and the return of the fuel into the tank is made by splashing.

 

To minimize measurement uncertainties, the only measured parameter used to calculate the test results was the weight of the portable tanks. Other parameters, such as vehicle speed, distance and time, were recorded for information purposes only. In order to avoid potential problems related to the instruments, two recently calibrated scales were available on-site. For each run, the portable tanks were weighed using the same portable scale. Furthermore, the scale was checked against a known weight of 120 kg before each series of weighing (Figure 13). The portable scale was not moved between the initial and final weighing for a given test run.

 

Figure 13. Scale checking using a calibration weight set.

 

In order to eliminate the influences of traffic and variations in driver response, testing took place on a closed-loop test track at a fixed speed of 105 km/h (65 mph), with a standard acceleration and braking protocol for all drivers. In addition, travel speeds were monitored throughout the tests using radars, and drivers were instructed by radio if it became necessary to adjust their travel speed. Moreover, the vehicles were instrumented with GPS, and GPS data was used to confirm vehicle speed. The drivers’ influence on the results was thus eliminated by strictly controlling the driving cycle.

 

Vehicle spacing was 0.8 km (0.5 mi.), which is within the limits stipulated by the practice (0.4 • 1.2 km,

¼ • 3/4 mi.)) (TMC 2016a).

Distance measurement was not a factor because for each run, all vehicles departed and arrived at the same point after travelling the same number of laps and following the same path along the track.

Summary

Table 5 presents the fuel consumption test results obtained for the HydraGen™ technology from Dynacert, expressed for the confidence level of 95%3.

Table 5. Summary of test results

 

Test segment	Test 1	Test 2
Test date	August 22, 2017	October 31, 2017
HydraGen™ brake-in mileage	11 495 km	24 181 km
Test results
Fuel savings	0.879 % ± 0.611 %	5.530 % ± 1.009 %
Fuel improvement	0.887 % ± 0.616 %	5.854 % ± 1.068 %

 

 

Emission measurements are showing significant decreases in emission levels between baseline and final test segment measurements, of almost half for carbon monoxide (CO), total hydrocarbons (THC), and for mono-nitrogen oxides (NOx). Emissions of CO₂ where practically unchanged between baseline and final measurements.

 

 

 

Disclaimer

This result refers only to the vehicle and specimen of technology tested according to the procedure and conditions described in this report. FPInnovations cannot guarantee the reproducibility of this result in particular operating conditions.

The representative of Dynacert observed the three segments of the tests performed on the product and validated the use of the HydraGen™technology on the test vehicle prior to the beginning of said tests. The representative of Dynacert also acknowledged that the tests he observed were conducted in conformity with the test protocol.

 

 

 

 

 

 

 

 

 

 

 

 

 

3 To calculate fuel savings, the difference between the the baseline segment ratio and the test segment ratio is divided by the baseline segment ratio, whereas for the fuel improvement, the same difference is divided by the test segment ratio.
