• Main Theory
• Four stroke Principle
• Four stroke are implemented, the first being the
  induction stroke, the second comprises the
  compression and ignition stroke, the third is the
  combustion stroke, lastly is the exhaust stroke.
• 2. Air/Fuel Mixture
• 14.71 ,ratio of air particles per fuel
  molecule, is actually what is called
  stoichiometric - or the ideal air/fuel ratio, at
  which temperatures are controlled and fuel
  economy is optimized
• 3. Ignition Timing
• The ignition point is dependent on the engine
  speed, and load

• Project Aim
• The design and implementation of an electronic
  circuit, which is able to optimize the ignition
  of the fuel mixture inside an engine.
• To design and develop a software system which is
  able control and optimize the firing angles so
  as to improve the ignition timings.

• Pressure Curve in the Combustion Chamber
• for Different Ignition Points
• Ignition(Za) at correct timing
• Ignition(Zb) too soon(ignition knock)
• 3. Ignition(Zc) too late

Software To Control the Ignition Controller and
Optimize the Ignition Timing The table below
contains the firing angles at different loads
and revolutions/sec of the engine
