Military Adaptation of Commercial Items: Laboratory Evaluation of the Code E-436 Engine
Abstract
The engine was installed in a dynamometer test cell at US Army Tank- Automotive Command (TACOM) and conventional dynamometer testing procedures were used to determine basic engine characteristics. The characteristics determined were full load performance, fuel economy at full load and part load, engine oil consumption, and engine heat rejection. During pre-endurance testing, the Code E-436 engine produced 378 observed kW (506.4 BHP) at full load, at rated speed of 2,600 RPM. The maximum torque during full load operation was 1439 Nm (1061 1b-ft) at 2,400 RPM. Minimum brake specific fuel consumption at full load occurred at 2,200 RPM and was 217 g/KWH (0.356 1b/BHP-HR). After the NATO endurance Test the engine produced 375.1 observed kW (503.0 BHP) at full load and rated speed. The maximum torque was 1423.8 Nm (1050 1b-ft) at 2400 RPM. The total lube oil consumption during the 400-hour NATO endurance was 19.7 kgs (43.4 lbs). Following the endurance test visual and dimensional inspection of the engine revealed all major engine parts to be in excellent condition except for pistons. Five out of eight pistons developed cracks in the pin bores. Though the engine completed the endurance test (400 hours) and was operated for a total of 582 hours, the engine is considered as having failed the 400-hour NATO test due to piston failure.
