If your car stalls when you are trying to turn it on, there could be a problem with spark plugs or damaged spark plug wires. The battery is most likely the culprit if your car has no power and won't start at all. Typically hopefully! If you notice that the engine is making rattling, pinging, or knock-like noises, your spark plugs might be to blame. It might be time to have them replaced — no one likes driving a sluggish, fuel-guzzling car.
In any car care matter, it's always best to follow the Manufacturer Suggested Maintenance Schedule. Review your vehicle's suggested maintenance schedule to see when to replace your spark plugs. You can typically get 80, miles on them before they need replacing. Blog Categories Blog Home. Changing spark plugs could be a good idea when Your check engine light comes on. The explosions provide the force to move the pistons up and down. Each cylinder contains an exact combination of fuel and air.
As the piston rises inside the cylinder, the spark plug ignites. The electrical arc creates the pressure to move the piston back down the cylinder and turn the engine.
The series continues to repeat as you drive your vehicle. Spark plugs could last up to a few years depending on the miles you drive and your engine maintenance habits. In this stroke, the piston compresses the air-fuel mixture in preparation for ignition during the power stroke below. Both the intake and exhaust valves are closed during this stage. Combustion: Also known as power or ignition. This is the start of the second revolution of the four-stroke cycle.
At this point the crankshaft has completed a full degree revolution. While the piston is at T. This stroke produces mechanical work from the engine to turn the crankshaft. After that, the main factor is the enlargement of the gap due to electrode wear and the rise in the required voltage is smaller.
The electrode progressively wears, causing the spark gap to increase, along with the increasing number of spark discharges.
When the gap exceeds a certain limit, the sparking performance deteriorates, which may prevent stable ignition of the gas mixture. When this happens, the horsepower of the engine falls, the fuel economy deteriorates and also the quality of the exhaust gas is adversely affected, so it is necssary to replace the plugs. The physical service life for a spark plug can be thought of as the number of kilometers driven until the spark plug begins to misfire. Misfiring causes not only wastage of fuel, but also irregular engine vibration and output drop.
In particular, for vehicles with emissions controls, misfiring can damage the catalytic converter, so using a spark plug all the way to the end of its physical service life is inexpedient economically.
