Testing: Chassis Dynamometer Efficiency Comparisons |
AUTOMOTIVE PROTOTYPE CHASSIS DYNAMOMETER TESTED PASSES AUTOMOTIVE LIFE CYCLE ANALYSIS INCREASES BOTH HIGHWAY AND CITY MILEAGE RATINGS HELPS TO DECREASE EMMISSIONS OPERATES ON AVERAGE 20 DEGREES COOLER THAN A RING & PINION LARGE AFTERMARKET POTENTIAL |
The SpinCo automotive prototype operated at 900 less engine RPM as compared to the ring & pinion gear at highway speeds (55mph to 70mph) with overdrive off. |
Testing was performed on a DynoJet Model 248x which has a timing accuracy of +/- 1 microsecond, a RPM accuracy of +/- 0.1 RPM, and a speed accuracy of +/- 0.01 mph. Data from the engines computer (PCM) was gathered using a lap top computer and ProScan software. Dynamometer results and PCM/ProScan data were matched according to run and then compared. The results are as follows: With the SpinCo gear installed the engine required less rpm under all driving conditions in first gear to achieve the same speed as compared to the ring & pinion. The on-board computer (PCM) calculated between 10 to 30% less engine load for first gear testing. With the SpinCo gear installed the engine required less rpm under all driving conditions in second gear to achieve the same speed as compared to the ring & pinion. The on-board computer (PCM) calculated between 20 to 30% less engine load for second gear testing. With the SpinCo gear installed the engine required less rpm during all tests in drive to achieve the same speed as compared to the ring & pinion. The on-board computer (PCM) calculated 14% less engine load for tests performed in drive. |
