The 793F has a Cat C175-16 quad turbocharged air-to-air aftercooled diesel engine that has enhanced power management capability for maximum hauling performance in your most demanding mining applications. The C175-16 is a 16-cylinder, four-stroke design that uses long, effective power strokes for optimum efficiency. Is compliant with U.S. Environmental Protection Agency emission requirements. The 20 percent net torque rise of the C175-16 provides unequalled lugging force during acceleration on steep grades and in rough underfoot conditions. Torque rise effectively matches transmission shift points for maximum efficiency and fast cycle times. High displacement, low rpm rating and conservative horsepower ratings mean more time on the haul roads and less time in the shop. The Cat Common Rail Fuel System is an electronically-controlled system senses operating conditions and regulates fuel delivery for optimum fuel efficiency. This precise and flexible fuel system gives the engine the ability to meet emission regulations without sacrificing performance, reliability or durability. The flexible core design of the MESABI radiator means easier serviceability along with long life and high durability. You have two starter options: The tank on the standard air start system is ground level serviceable, while the electric start option allows the air system to be totally removed from the truck.
