Mô tả chi tiết sản phẩm

DESIGN The 3512C HD is a 12-cylinder, four-stroke design that uses long, effective power strokes for more complete fuel combustion and optimum fuel efficiency. EPA COMPLIANT Where applicable, the 3512C engine is compliant with U.S. Environmental Protection Agency emission requirements. ALTITUDE COMPENSATION Designed for maximum operating efficiencies at altitudes under 4267 m (14,000 ft). HIGH TORQUE RISE The 23 percent net torque rise 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. ENHANCED LIFE High displacement, low rpm rating and conservative horsepower ratings mean more time on the haul roads and less time in the shop. OIL RENEWAL SYSTEM Optional oil renewal system extends engine oil change intervals from 500 hours to 4,000 hours or more to increase machine availability and reduce costs. VIBRATORY PLATE COMPACTORS Computerized system electronically protects the engine during cold starts, high altitude operation, air filter plugging, high exhaust temperature and engine overspeed (ARC). Optional Engine Pre-Lubrication builds up oil pressure before cranking providing additional wear protection. FUEL EFFICIENCY The engine provides additional retarding by running against compression on downhill hauls. During retarding applications the engine ECM does not inject fuel into the cylinders for exceptional fuel economy.
