Ignition Coil 118257

Ignition Coil (Part No.: 118257)

Function:

The ignition coil (Part No. 118257) is a crucial component in the engine's ignition system. Its primary function is to act as a high-voltage transformer. It steps up the low voltage from the battery or generator (typically 12V or 24V) to a very high voltage (thousands of volts) required to create a powerful spark at the spark plug.

Key Features & Purpose:

This high-voltage spark is essential for reliably igniting the air-fuel mixture within the combustion chamber. The coil ensures precise and strong ignition, which directly impacts engine performance, fuel efficiency, and emissions control. A properly functioning coil is vital for stable engine operation, smooth starts, and complete combustion.

Usage & Handling:

Replacement: It is used as a direct replacement for faulty coils in gas engines.

Installation: During use, it must be correctly installed on the engine block or ignition module as per the engine's specific configuration. Electrical connections must be secure and clean.

Maintenance: The coil is typically a maintenance-free component but requires periodic visual inspection for physical damage, cracks, or carbon tracking. It should be kept clean and dry.

Testing: If ignition issues arise, the coil's primary and secondary resistance can be measured with a multimeter against OEM specifications to diagnose failures.

In summary, the  ignition coil 118257 is a vital part responsible for generating the spark needed for combustion, ensuring the engine runs reliably and efficiently. Correct installation and routine checks are necessary for optimal function.
