ACCELERATION PERFORMANCE OF HIGHWAY DIESEL TRUCKS

LEVEL ROAD ACCELERATION PERFORMANCE MEASUREMENTS OF RANDOMLY SELECTED INTERCITY DIESEL TRUCKS ARE PRESENTED. THE RATIO OF GROSS COMBINATION VEHICLE WEIGHT TO GROSS ENGINE HORSEPOWER IS CORRELATED WITH ACCELERATION PERFORMANCE. TEST RESULTS ARE PRESENTED IN GRAPH FORM DISPLAYING DISTANCE VS. TIME, SPEED VS. TIME, AND DISTANCE VS. SPEED FOR WEIGHT TO POWER RATIOS OF 100, 200, 300, AND 400 POUNDS PER HORSEPOWER. THE EFFECT OF HIGH TORQUE RISE ENGINES WITH 5 SPEED TRANSMISSIONS AS WELL AS TRANSMISSION SHIFT TIME ON ACCELERATION PERFORMANCE IS ALSO REPORTED. A GRAPHICAL DETERMINATION OF PASSING TIME AND DISTANCE FOR A LOW SPEED PASS MANEUVER IS ALSO PRESENTED, BASED ON ACTUAL ACCELERATION PERFORMANCE DATA. /HSL/
