Your diesel filter water separator explained
Did you know that condensation in your diesel engine can get into your fuel system, contaminating your diesel? This is a less of a problem for petrol cars, as diesel engines (unlike petrol engines) don’t have vapor pressure to displace air. In other words, as the fuel tank heats up, the air expands and is forced out. Unfortunately, when the tank cools down, humid air is sucked back into the tank and water condenses on the cooler tank walls.
Everything you need to know about diagnosing your ignition coils
The ignition coil (also known as a spark coil) is one of the most important elements of the ignition system used with a gasoline engine. The ignition coil generates an electric charge converting the low voltage into high voltage. High voltage, which in the final phase is converted by a spark plug into a spark - which ignites the fuel-air mixture accumulated in the combustion chamber.
How to check and replace a lambda sensor?
A lambda sensor, or oxygen sensor, is a vital element in your car’s emissions systems, ensuring that your fuel mixture has the right amount of oxygen for efficient and environmentally-friendly combustion. In this blog post, we’re going to briefly look at what a lambda sensor is, how it works, when you should check it and how to replace it.
How to fit spark plugs
Without spark plugs, your petrol engine won’t start or run. But, for the engine to run smoothly they need to be maintained at regular intervals (your owners’ manual will tell you how often this is needed). Warning signs that your spark plugs need to be replaced include difficulty in starting the car, a rough sound when idling, misfiring, reduced engine power and increased fuel consumption.
How to test glow plugs
Glow plugs ensure your diesel car starts – no matter how cold it is. Located in every cylinder of your engine, they ensure your car burns fuel efficiently, with minimal polluting gases. But, what can you do if you start to suspect that your glow plugs aren’t working as well as they should be?
