cummins engine turbocharger , Iran

The Cummins engine turbocharger is designed as a hot gas type with floating bearings (full floater). The turbine wheel is manufactured from superalloy Inconel 713C with continuous temperature resistance of 950 degrees Celsius. The turbine wheel diameter in the HX35 model (for 6BT) equals 56 millimeters and in the HX40 model (for 6CT) equals 60 millimeters. The compressor wheel is manufactured from aluminum alloy 2618 with hard anodized coating and a diameter of 50 to 76 millimeters. The compressor pressure ratio in standard models varies between 2.2 and 3.5 bar. The maximum rotor speed in smaller turbochargers reaches 150,000 revolutions per minute. The floating bearings are placed on a 4340 steel shaft with radial clearance of 0.025 to 0.060 millimeters. The turbocharger lubrication system is cooled with oil pressure of 2.5 to 5.0 bar and a flow rate of 3 liters per minute.

The exhaust gas temperature entering the turbine is controlled between 650 and 750 degrees Celsius at rated conditions. The mass air flow rate in the HX35 model is approximately 0.35 kilograms per second and in the HX40 model reaches 0.45 kilograms per second. The adiabatic efficiency of the compressor at the design point is 76 to 78 percent. The turbo lag response time from throttle to full boost pressure is approximately 1.2 to 1.8 seconds. The maximum boost pressure in fixed geometry models reaches 2.2 bar absolute. The combined water-oil cooling system controls the temperature of the turbine housing. The oil returns to the engine after passing through the bearings and dissipates heat. The turbine housing is cast from heat-resistant alloy cast iron with 18 percent nickel and 5 percent chromium. The service life of a Cummins turbocharger under standard conditions is estimated at approximately 15,000 operating hours.You can order and buy cummins engine turbocharger from Iran by contacting us through whatsaap and email.
