- SS is Difficult to machine for high finish
- Galling or friction welding when moving up and down(like piston & cylinder; valve stem & gland etc)
- Most of the engines work in the range 400 to 900°C and it is called Sensitization zone and SS will lose Chromium and SS becomes steel and start rusting and cracking.
- Stainless steel has high thermal expansion(1.6times steel/CI) and low thermal conductivity(SS has low thermal conductivity , 25% of CS. The bore area will have high temperatures and high thermal expansion and distortion and mis-alignment of cylinder piston and engine bore are expected.
The electrohydraulic control mechanisms of the ME engine replace the following components of the conventional MC engine: Chain drive for camshaft Camshaft with fuel cams, exhaust cams and indicator cams Fuel pump actuating gear, including roller guides and reversing mechanism Conventional fuel pressure booster and VIT system Exhaust valve actuating gear and roller guides Engine driven starting air distributor Electronic governor with actuator Regulating shaft Engine side control console Mechanical cylinder lubricators. The Engine Control System of the ME engine comprises: Control units Hydraulic power supply unit Hydraulic cylinder units, including: Electronically controlled fuel injection, and Electronically controlled exhaust valve activation Electronically controlled starting air valves Electronically controlled auxiliary blowers Integrated electronic governor functions Tacho system Electronically controlled Alpha lubricators
