Diesel does not require a spark to combust.
a petrol engine uses petrol which is highly combustable, so it can be ignited by a spark. that is why petrol engines have spark plugs. diesel is an oil based fuel, and takes higher temperatures to ignite, it cannot be as easily ignited by a spark and sometimes cant at all, so diesel engines have no spark plugs and the fuel is ignited under extreme heat due to pressure.
i have no idea!!! sorry to whoever posted this, but im looking 4 the answer too! A Dodge diesel doesn't use spark plugs. Diesel engines fire on compression. wow i cant believe there is two of you out there.... heres your signs.
They are located at the end of the spark plug wires.
if you cant find the spark plugs then you probably shouldn't be working on your car if you cant answer the question maybe you shouldnt leave answers like these
You cant
you have to buy new spark plugs then take the old ones out with a spark plug wrench and put new ones in that's it pretty simple i cant believe you didnt know that lol
Ok first off, most cars today use gasoline engines and not diesel engines so that has to be addressed as a factor (you cant run a diesel engine on spark plugs they use GLOW plugs) so assuming you are using a gasoline engine and not diesel then we can continue SO assuming you are using a gasoline engine that uses SPARK plugs in the first place I do not understand the question. BUT, Im assuming once again that you are wondering whether the different brands and or changing them out will yield better mpg The answer to that is yes on all counts. New spark plugs provide a better spark than older ones and as such increase the ratio of fuel actually burned inside the engine and not wasted. So it increases the mpg there The difference between brands are many and the materials each brand uses also varies. But your car comes with normally piss poor plugs to start with so picking a relatively cheap and well made product can give you the same results as your typical run of the mill OEM product. I would take the extra money and buy a more higher end model but not the most expensive ones. The reason is that the higher end spark plugs last longer in between changes, increase horsepower, increase mpg, and are made from better quality. They are better all the way around. I hope that answered your question
A Petrol engine use petrol that it ignites to cause an explosion in the cylinders, where the diesel engine works by compressing the mix of diesel and air, expose this to heat to make it explode but over a longer time. So a diesel engine has no spark plugs. The diesel needs pressure and heat, while petrol is explosive, will explode. So the two cannot be used together.
the spark plugs are set down inside the valve cover. you have to remove the 4 "box" looking tops of the spark plug wires, and use a good long extension to get to them.
You cant chance the spark plugs with out removing the manifold sorry dude i have tried every possible way there is and its not going to happen :(
While diesel engines do use fuel with the highest percentage of ethanol (Grain alcohol), they do not use 100% ethanol.
You broke a plug wire- don't care if you cant see it... I CAN!
