MAJOR CAUSES OF ENGINE BREAKDOWN OR SUDDEN STOPPING.

 MAJOR CAUSES OF ENGINE BREAKDOWN OR SUDDEN STOPPING.

1) Overheated engine 

2) Chocked catalytic converter 

3) Electrical issues in the Ignition System.

4) Inadequate Transmission Fluid leading to increased friction in the gearbox.

5) Loose engine Bolts. 

CAUSES OF ENGINE BREAKDOWN.

- Engine overheating.

As the fuel burns the Chemical Energy is changed to Heat Energy. The engine further changes the Heat Energy to Mechanical Energy which propels the car.

If this Heat in the Engine bay goes beyond the normal range, the pistons and the engine start expanding. Engine expansion compresses the cylinder decreaing their diameter and hence icreasing the friction between the the piston and the Cylinder Walls as the piston moves up and down.

Eventually if the temperature keeps rising the piston is tightly held by the cylinder walls and its unable to move again and this  leads to a sudden engine stop.

CAUSES OF ENGINE OVERHEATING.

1) Defective Radiator Cap.

2) Leakage in the cooling system 

3) Condensed Engine coolant 

4) Blockage to coolant circulation delivery galleries.

5) Low Engine Oil level.

6) Broken or Defective Water Pump.

Super alloy and its amazing components

 Composition: OF super alloy

These alloys are referred to as iron-base, cobalt-base or nickel-base super alloys. They contain nickel, chromium, cobalt and molybdenum as major alloying elements; Most super alloys have a maximum service temperature of about 1000°C for non-load bearing components.

Iron base super alloys generally contain composition of 32% to 67% iron, from 15% to 22% chromium and from 9% to 38% nickel.

Cobalt-base super alloys generally contain composition of 35% to 65% cobalt, 19% to 30% chromium and up to 35% nickel. Cobalt (Co) is white-colored metal that resembles nickel. These super alloys are not as strong as nickel-base super alloys in this they retain their strength at higher temperatures.

Nickel-base super alloys are the most common of the super alloys and they are available in a variety of compositions. The composition of nickel is from 38% to 76%; they also contain up to 27% chromium and 20% cobalt. Common alloys in this group are the Hastelloy, Inconel, Nimonic, Rene, Udimet, Astroloy and Waspaloy series.
