Should spark plugs rotate?
The plugs should be rotated when reinstalled. This balances the electrode wear so that the plug center electrode and side electrodes wear evenly, prolonging the life of the plug.
How often should I change the spark plugs in my car?
However they should be inspected every 30,000 miles or so, which will give you an idea of the health of the engine. Consult your car’s manual, which should list the recommended intervals for changing your spark plugs. If you can’t find a recommendation, it’s worth removing them and checking their condition.
Why do spark plugs need to be changed in a diesel engine?
Without the spark plug the petrol engine wouldn’t be able to run. Spark plugs are not used in diesel engines, which fire instead by simply compressing the fuel in the cylinders; no additional spark is necessary. Why do spark plugs need to be changed? Spark plugs need to be maintained properly if the engine is to operate smoothly.
Where are the spark plugs on a four cylinder car?
In general each cylinder has one spark plug (there are cars with two spark plugs per cylinder, but these are in the minority). So a four cylinder car will have four spark plugs. They can generally be found on the top, or side of the engine, sometimes under an engine cover, and sometimes not.
Why do spark plugs need to be maintained?
Spark plugs need to be maintained properly if the engine is to operate smoothly. Neglect them and you could experience a number of problems. For example, starting the engine may become a problem; you might have to turn it over several times before it fires, and this may flatten the battery over time.
How is a piston connected to a rotary engine?
Before you get your head around the concept of the rotary engine, let’s review the basic workings of the normal piston-combustion engine. The piston is connected to a crankshaft via a connecting rod, and as it moves up and down it makes the shaft rotate.
How is the piston connected to the crankshaft?
The piston is connected to a crankshaft via a connecting rod, and as it moves up and down it makes the shaft rotate. Opposite the crankshaft is a combustion chamber with valves that let in fuel and air, and let out exhaust gasses.
Why does a Honda engine spin at 10, 000 rpm?
• Due to the nature of the engine they are internally balanced – the rotors act like spinning counterweights, phased to cancel each other out. This means there are less vibrations, so the engine is smoother and will spin to higher revolutions (10,000 rpm is by no means unheard of) without damage.
