    • Shown here is the battery ignition system.there are others like magneto ignition systems and various other ignition methods.the battery is connected to primary winding via ignition switch which when turned on completes the circuit.now there are breaker points in the circuit that is operated using a cam connected to the engine. This essentially determines the ignition timing.when the breaker points come into contact the current flows into the primary winding inducing a magnetic field in it.Now when the breaker points open the current flows into the capacitor. Now the primary winding induces a current in the wire which flows in same direction of primary current. Hence this helps in charging capacitor to a higher voltage than battery .now current starts flowing from capacitor and not the battery. This reverses the magnetic field in the primary winding.the sudden reversal induces a high voltage in secondary winding which then carries current to distributor.the distributor decides the time at which each spark plug must activate
       
    • I feel that electric cars are the  next revolution that is going to happen in automotive industry.this is because wide sources of energy is available that can be converted to electricity efficiently.Moreover the rapid improvement in battery technology with promotion of nano cell technology will the pave the path for these vehicles.Emissions will hence decrease when multiple renewable energy sources are used. Second, electric cars make less noise and are going to be more economical in future.they have fewer moving parts thus avoiding wastage of energy and leading to high efficiency.
      The electric cars don't require any power train units like gearbox thus enabling a single pedal drive.This will make the driving of a car simple.Just imagine a car with just one pedal and no gears to shift.it is phenomenal
    • What is the Length of the crankshaft????
    • The flywheel does not store force; it stores kinetic energy. This is the source of energy to keep the crank turning during the compression strokes when the cylinder pressure is retarding crank rotation.
      Imagine that you start a small, single cylinder engine, such as a lawnmower engine, With the lawnmower blade in place, the engine runs just fine, but in many cases if you remove the blade, the engine will not run at idle speed. Why? Because the blade acts as a part of the flywheel, storing energy for the compression stroke. If you remove the blade, there may not be enough energy stored to complete the compression stroke.

    • Flywheel is storing device because during ignition strokes its stored a power and due to suction stroke there is no power generated in engine so these type energy for rotation is provided by the flywheel.....
