I’ve long been skeptical of products promising significant fuel economy improvements, especially when improvements approach 10 percent. I’ve gone on record that I would write about them only if they prove their claims with tests strictly following SAE J1321 and TMC RP1102 procedures conducted by an independent test facility.
Hy-Drive Technologies, 888-359-5697, hy-drivesaves.com, had the test done by Professional Services Industries, Portland, OR.
Hy-Drive makes an on-board hydrogen generator that uses electrolysis to separate hydrogen and oxygen in water. The hydrogen is injected into the air intake. The laws of physics state that by burning the hydrogen, you recover less power than you use extracting it. But when burned with diesel, the hydrogen evidently improves combustion efficiency of the fuel, resulting in a better burn for improved fuel mileage and lower emissions. The tests yielded about a 10 percent average improvement.
From being a skeptic, I’ve become a believer. So far, Hy-Drive is the only manufacturer to present test results.
Despite better maintenance, loose wheel incidents still occur, often with disastrous results.
As temperatures change, metals expand and vibration can loosen wheel nuts. When surface rust or corrosion occur, further wheel end vibration loosens nuts.
Some devices show when loosening has happened, but the Zafety Lug Lock, 888-381-2355, www.spectraproducts.ca, actually prevents hub-piloted lug nuts from backing off.
Made of polymer, shaped to fit over two adjacent wheel nuts with a corrugated connector bar between to absorb any differential vibration, four or five locks are used per wheel, depending on configuration. They hold the corners of the nuts to keep them from backing off. During inspection, you can easily verify that all nuts are in proper position.
For most drivers, accurate weights on each axle set are essential data. To save time and money at commercial scales and to avoid fines, on-board scales continue to grow in popularity.
Right Weigh Load Scales, 888-818-2058, rwls.com, introduced the E-Z Weigh digital scale that calibrates quickly and easily in two operations. Just get an empty scale weight, push a button and enter the axle or tandem weight. Push one more button and the weight is locked in. Then get loaded, either fully or partially, and repeat the process.
With two established set points, the E-Z Weigh computes any weight on the air suspension and displays it on an easy-to-read, bright LCD display. It mounts in about 10 minutes, reads in pounds or kilograms, and costs less than $300. Accuracy is within 250 pounds.
Hendrickson, 800-356-6737, hendrickson-intl.com, introduced the Aero Clad bumper, starting with models for the International ProStar. The two-piece molded bumper increases ground clearance and improves cooling air flow. Its high strength eliminates the need for structural backing while saving weight. Other models will follow.
The biggest buzz and the longest lines were at the Bose display. That’s Bose, the audio company. They finally released their truck seat, the Bose Ride, 800-721-2673, bose.com, using noise-cancellation technology, the same technology used in their Quiet Comfort head sets. The seat uses 3,500 watts (a high-end stereo is 200 watts) to measure cab movement and, within milliseconds, move the seat to counter any harsh movements of the truck. Imagine driving into a 4-inch deep pothole and not feeling it.
The seat is expensive, just less than $6,000, but Bose sold a number of them at the show. Through November, installation is free. Crowds lined up to try the seat on a motion-duplicating platform mounted in their trailer. LL
