Reliable and durable

Cummins

‘K50 series’ diesel engine with strong

regrindable crankshaft, high strength connecting
rod, low pressure fuel lines, STC (Step Timing
Controls) injectors and high volume coolant system
make ‘K50 series’ generating sets, more reliable
and durable. Engines have clocked millions of hours
operating in some of the world’s most demanding
conditions. Current engines are regularly upgraded
with new technologies for better performance and
economy. The ultimate proof of superior
performance and reliability is the fact that Cummins

entities worldwide source these engines from
Cummins India for their markets.

Unmatched warranty
