Product Details:

ATLAS COPCO TCD2012 refers to the Deutz TCD2012 series water-cooled inline diesel engine specially configured as the original power unit for Atlas Copco portable air compressors, mobile drilling rigs and other off-road construction equipment. This engine family includes four-cylinder and six-cylinder variants, adopting Deutz DCR common rail fuel injection system and EMR3 electronic engine controller, featuring turbocharging and charge air cooling for stable power output and low fuel consumption. The four-cylinder version has a displacement of 4.04 L while the six-cylinder version reaches 6.06 L, with power ranging from 66 kW up to 155 kW according to different tuning options, meeting EU Stage IIIA and US EPA Tier 3 off-road emission standards. It is designed for long-hour continuous operation under severe working environments with heavy dust, strong vibration and wide temperature fluctuation. It provides reliable cold start performance at low ambient temperature, and the service points are arranged on a single side for convenient routine overhaul. Users can carry out fault diagnosis, parameter reading and calibration by professional Deutz diagnostic software. Built-in protection functions include overspeed, low oil pressure and overheating protection to avoid irreversible engine damage during unattended running. We can supply complete engine assemblies as well as separate spare parts including cylinder head, crankshaft, fuel injectors, sensors and cooling components for Atlas Copco mobile equipment overhaul. It is widely used as the matched driving power for Atlas Copco Mobilair portable compressors, rock drills and construction machinery.
