LEHT8893-00 (8-08) ©2008 Caterpillar All rights reserved. Performance is based on SAE J1995 standard conditions of 29.61 in. Hg (100 kPa) and 77° F (25° C). The curves shown are for a standard engine without fan, but equipped with air compressor and fuel, lubricating oil, and water pumps. RATING DEFINITIONS AND CONDITIONS GEARING CONSIDERATIONS The C15 On-Highway Diesel Engine offers 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. The general principal drivers should follow is that of the “gear fast, run slow”strategy to achieve optimal performance. For the best balance of performance and fuel economy, spec axle ratios and tire sizes according to the following: • 80,000 lb GCW or less Less than 1750 lb-ft: 1400 rpm @ 65 mph (105 km/h) 1750 lb-ft and above: 1325 rpm @ 65 mph (105 km/h) • 90,000 lb GCW or more 1500 – 1600 rpm @ cruise speed Multi-Torque: • 80,000 lb GCW or less 435-hp, 1550/1750 lb-ft: 1325 rpm @ 65 mph (105 km/h) 475-hp, 1650/1850 lb-ft: 1325 rpm @ 65 mph (105 km/h) Maximum recommended engine speed at cruise is 1500 rpm. The minimum startability requirements are 10% for pick-up and delivery, 14% for linehaul, 20% for on/off highway, and 25% for off-highway. At peak torque rpm in top gear, the recommended gradeability is 1.8% (1.5% minimum). At cruise speed in top gear, 1.0% is the ideal gradeability. To optimize your truck’s performance characteristics, a computerized spec’ing tool called Design Pro is offered by your Caterpillar dealer. It calculates effects of various driveline variables on engine operation such as transmissions, axles, and tires. This analysis allows you to verify that your truck’s driveline specifications are best suited to your application. ELECTRONIC FEATURES ■ Real time clock with date and time stamping of critical events ■ Electronic self-diagnostics ■ Electronically tabulated total fuel consumption, hours, idle time, and miles ■ Battery backup ■ Quick stop recorder ■ Compatible with Caterpillar Electronic Technician (ET) ■ Cold weather startup strategy and electronic idle control functions ■ ECM storage of operational, maintenance, diagnostic codes and diagnostic data ■ J1939 compatible ■ Customer selectable, re-programmable operational parameters: - Adjustable low idle rpm - Automated Transmission compatibility - Cooling fan control - Cruise control with exclusive Soft Cruise - Customer password protection - Engine Monitoring System — warning, derate, or shutdown - Enhanced theft deterrent and secure idle (Cat Messenger or Pocket Tec required) - Fleet Information Software capability - Idle shutdown timer & override - Maintenance monitor [miles (km) or hours] - OEM parameter lockout - Progressive shifting and gear down protection - Vehicle speed [mph (km/h)] limiting and protection ■ Programmable Power Take-Off (PTO) functions: - Adjustable maximum engine rpm speed - Adjustable minimum engine rpm speed - Adjustable ramp rate up or down between PTO set speed(s) - Adjustable rpm “bump” intervals - Adjustable speed control [mph (km/h)] of vehicle while in PTO mode - Limit engine torque to driven equipment - Multi-speed PTO set speed capability - Kick-out vehicle speed limit - Selectable PTO configuration for “in cab” or station of remote operation
