How are spark plugs and fuel injectors used?
Spark plugs are used in Spark ignition engine(petrol) to ignite fuel and air mixture in combustion chamber while fuel injectors are are used in combustion ignition engine (Diesel) where in the fuel is sprayed with help of fuel injectors into combustion chamber, however modern petrol engine are also using CRDI…
What happens if you have a bad fuel injector?
In several situations, a leak in a vehicle’s fuel injector can lead the fuel/air mix to become so rich that it burns out the car’s catalytic converter in the long run. It may not be that easy to diagnose a clogged fuel injector as they are similar to bad coil, bad spark plug, or broken spark plug. Maybe one cylinder or more fails to fire.
What kind of spark plug is used in a diesel engine?
In Spark Ignition engines (petrol) spark plug is used and in Compression Ignition engine (diesel) fuel injectors are used.
What causes a fuel injector to leak over the engine?
So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an injector will leak is if, the injector body or nozzle cracks.
How does the fuel injector work in a diesel engine?
The fuel injector is fitted on the Diesel Engine or CI Engine. (In Diesel engines don’t require any spark plug and the required heat to, Ignite the fuel is generated due to compression of air). This component generates the spark with the help of DC current.

What’s the difference between a spark plug and a fuel injector?
In term of price point, Spark Plug is available comparably less price then Fuel injector. The Fuel Injector is a costly component. So these are the difference between Spark Plug and Fuel Injector, I hope you are able to understand the difference between these.
