INTRODUCTIONThe basic requirements

INTRODUCTION
The basic requirements for reciprocating engine ignition systems are similar, regardless of the type of engine.
All ignition systems must deliver a high-tension spark across the electrodes of each spark plug in each cylinder of the engine in the correct firing order.
At a predetermined number of degrees ahead of the top dead center position of the piston, as measured by crankshaft travel in degrees of rotation, the spark occurs in the cylinder.
The potential output voltage of the system must be adequate to arc the gap in the spark plug electrodes under all operating conditions.
The spark plug is threaded into the cylinder head with the electrodes exposed to the combustion area of the engine’s cylinder.

PENDAHULUAN
persyaratan dasar The untuk sistem pengapian mesin reciprocating yang sama, terlepas dari jenis mesin.
Sistem pengapian All harus memberikan percikan tegangan tinggi di elektroda setiap busi di setiap silinder mesin di urutan penembakan yang benar.
At jumlah yang telah ditetapkan derajat di depan posisi pusat mati atas piston, yang diukur dengan wisata crankshaft dalam derajat rotasi, percikan terjadi di dalam silinder.
The potensial tegangan output dari sistem harus memadai untuk busur kesenjangan di elektroda busi di bawah semua kondisi operasi.
The busi threaded ke kepala silinder dengan elektroda terkena area pembakaran silinder mesin.
