Spark plugs play a critical role within the ignition system of petrol vehicles, with two main functions. One is to ignite combustion to start the engine and the other is to move heat away from the combustion chamber. While installing spark plugs should be a relatively straightforward task for any skilled technician, applying the right torque is not so simple and requires particular care and attention. This article outlines the recommended way to apply torque to a spark plug installation and the consequences of under and over-torque.
The basics of a glow plug are easy to explain. They are essential for ignition in diesel-powered engines (as opposed to spark plugs in petrol engines); they heat the air/fuel mixture in the engine so it ignites easily under compression; they are built to be long-lasting and work reliably no matter what happens. However, occasionally external factors or faults with other components can lead to issues with glow plugs. Owing to their rarity, these can easily be missed or wrongly identified.
All ignition systems for modern petrol engines use ignition coils for the same basic function: to create the high voltage required to produce a spark at the spark plug. Aftermarket professionals will be familiar with their purpose and basic attributes – but they may not know about the in-depth scientific principles they rely on. Here, we explain how electromagnetism is at the heart of an ignition coil’s essential role…
Especially when working with mechanical ignition systems, it’s crucial to understand ignition coil charge-up and dwell time. This guide will give you everything you need to know about how charge-up works for different ignition systems and engine speeds – and how common ignition problems can arise.
When it comes to wiper blades, they’re an overlooked yet essential feature on cars. Wiper blade replacement can also be delayed, and common signs of worn wiper blades can be missed too.
