EFI Retrofit on Penzadieselmash D50 Engine

HEINZMANN has successfully finished the conversion of Ukrainian TEM2 locomotive in field use from conventional to electronic fuel injection control.

The challenge:
The electronically actuated E-PPN Injection Control Valves were used instead of the hydraulic-mechanical speed governor of the Penza D50 combustion engine: 6 cylinders in line, 620 kW at 750 rpm, turbocharged.

The solution:
By means of HEINZMANN's turnkey solution, fuel consumption of the locomotive was reduced by over 14 % and operating characteristics as well as maintenance requirements were improved. At the heart of the PLN extension kit is the electronically actuated LAVINIA E-PPN Injection Control Valve which provides new qualities to conventional mechanical fuel injection systems (PLN). Together with the high-performance MVC 01-20 controller it optimises the combustion process in a map-controlled approach. Smooth engine running, reduced engine loads and improved emissions behavior are achieved via balanced injection quantities across all cylinders.
