CAT C-16 / C-15 Diesel Engine Specs for Heavy-Duty Trucks

Caterpillar C-16 Truck Engines offer a wide operating range and high torque rise which promotes the use of transmissions with fewer gears. Even with this built-in feature, heavy/specialty haulers must remember their trucks should be geared to achieve the appropriate compromise between startability and desired road speed. Typical loads of 80 000 Ib or less are less affected by improper drive train specing than are heavy haulers. In general, either application shares one similar recommendation - gear fast/run slow is essential for good fuel consumption. If any of the following conditions are present, special attention should be given to proper transmission and axle specifications. A complete Caterpillar Truck Engine Pro (TEP) C-16 analysis is available from your local Caterpillar or truck dealer.
