Niitsu Turbo wants you can learn more about our enthralling turbochargers products. As a diesel turbochargers manufacturer and exporter ourselves, we wish to help the general public to grasp on basic knowledge on turbochargers. The history of turbochargers has interesting findings to its roots dated back to 1885. Know more about the basic technology behind the turbocharger comparing to conventional internal combustions among engines. Learn more on the advantages that turbochargers offer in terms of engine performance, fuel consumption and carbon dioxide emissions. Understand what it takes for the technology to breakthrough into mass production in today's era. Furthermore, you will find information on diesel turbochargers care and maintenance as well as diagnostic aids often overseen.

  • Fully synthetic oils and mineral oils do not mix. In severe cases they can coagulate.
  • When engine's oil pressure is low, the turbocharger will be the first component to fail in engine.
  • The most common contaminants found in the oil are 'free floating' carbon deposits, fuel and the left over from excessive combustion.
  • Common diesel turbocharger with rotor speeds of 200,000 R. P.M. will have an approximate blade speed on the compressor wheel of 850 miles/hour.
  • Many operators assume, quite wrongly, that if they run an engine with dirty or contaminated oil, the oil filter will remove any foreign matter before it reaches the engine and more importantly the turbocharger.
  • 4 seconds of oil delay will contribute to journal and thrust bearing wear. Delay of just 8 seconds can cause irreparable damage. The damage is not immediate but will take place fully in few days.
  • The average temperature of the exhaust gas, at the entry point to a diesel turbo, is 800 degrees centigrade. A petrol engine can reach 1000 degrees, glowing bright yellow. Hot enough to melt window glass.
  • Latest turbocharger impellers can rotate up to 220,000 revs per minute comparing to the ones on Boeing 747 at about 7,000 revs.
  • Airflow into the compressor impeller in a turbocharger can reach a travelling speed of mach 1.
  • The "hot end" turbine blades in a turbocharger are made from a high nickel content alloy, as used in jet aircraft engines. A blade will travel in the region of 820 mph at average engine speed, and the exhaust gas entering it will be supersonic
  • Turbochargers have the ability to accelerate from 20,000 revs per minute to 150,000 revs per minute in just a mere second.
