THE PROGRESS OF THE CAR ENGINE part1

The car engine as we know it is one of the most engineered items that man has developed since approx 1900 AD

 

It comprises of two parts:

 

  1. The “Top Part” which is everything above the engine block
  2. The “Bottom Part” – the engine block (the forgotten part which is below the top half )

 

From 1900 AD the engine has need improvement continuously to fit the needs of the people:

 

  1. Change to 4 cylinder to give more power
  2. Battery spark ignition and starting
  3. Automatic advance and retard of ignition – better economy and power
  4. Multiple carburettors – more power – less economy
  5. Superchargers – more power – less economy
  6. Turbo-chargers – more power – better economy
  7. Polishing and grinding ports – performance
  8. Greater than 4 cylinders – more power – less economy
  9. Overhead valves – more power – better economy
  10. Fuel injection – more power – better economy
  11. Electronic fuel injection – more power – better economy

 

By this time it was about 1980 AD where it was obvious that Pollution was also a factor!

 

Attempts to improve this were added:

 

  1. Exhaust recirculation
  2. Fuel tank breathing
  3. Crankcase ventilation
  4. Catalytic converters
  5. Try using Diesel engines more
