ANALISA PERBANDINGAN PERFORMANSI SINGLE DAN DOUBLE TURBOCHARGER PADA CUMMINS ENGINE K50 SERIES
Abstract: Application
development engine in the heavy equipment is currently lead to the development
of environmentally friendly technologies but with a better performance without
changing the size or dimensions of the engine. Performance comparison analysis
between Cummins engine applications which use single and double turbocharger to
the performance, efficiency and fuel comsumtion required to provide a reference
for users of heavy equipment unit (customer). This research was conducted at
PT. Altrak Balikpapan branch in 1978 as a distributor of Cummins engines
Indonesia. The research object is the Cummins engine type "K50"
series with KTA-50 engine models and KTTA-50. Achievement of maximum engine
power in the can with the provision of 100% load at 1900 rpm engine speed,
which amounted to 1798 HP at KTA-50 and 1993 HP at KTTA-50. The increase in the
value of the torque which can be different from the values of engine power,
because the maximum torque is not in a position rated speed but at 100% load at
1500 rpm engine speed. This position is often referred to as the peak torque
and the maximum torque values in may of 1487 lb.ft at KTA-50 and 1656 lb.ft
at KTTA-50. The result of the calculation is theoretically found also that with
the increase in engine power then an increase in fuel consumption linearly. The
thermal efficiency of the engine KTTA-50 amounted to 42.29% larger than the
engine-50 summit that only 42.23%.
