It’s critical to measure the gap to make sure that your spark plug lasts long and provides maximum efficiency in your engine. Pre-gapped means that the device is pre-measured to work in different engines. Most lawn mower manufacturers claim that their plugs are pre-gapped, but this doesn’t mean that the gapped plugs are still in place or that the plugs are gapped to your mower’s engine. High cylinder pressure needs a higher voltage for the spark to happen. Spark voltage or electric pressure corresponds to the distance the spark can cross at a given environment and air pressure between the spark plug gap. Also, fuel with high alcohol content needs small spark plug gaps and a lower A/F ratio. That makes it difficult for the spark to occur. For example, when the engine is under load, the pressure in the combustion chamber is high due to air aspiration. Note that the shape, size, and style of the spark plug corresponds to various factors for the best engine and spark plug performance. Likewise, a too-small gap means the spark lacks enough space to generate the required power to ignite the fuel, something that leads to high tailpipe emissions and low power. That means if the gap is too large, the spark produced in the center electrode won’t travel to the ground electrode completely, which means the system needs to work harder to ignite the air/fuel mixture. The gap has an effect on the exertion and operation by the ignition system to start the mower’s engine. So, what happens when spark plugs are not gapped properly?Ī lack of having the right gap on the spark plug leads to cylinder misfires, premature wear, and ignition system stress.
#ARE SPARK PLUGS PRE GAPPED MANUAL#
You’ll find the recommended gap specification on the mower’s manual or on the emission sticker.Ī lawn mower’s engine operation and efficiency depend on the accuracy of the gap. The distance of the gap on a spark plug depends on the amperage and voltage generated by the ignition coil. Why is the Gap on the Spark Plug Important? You can use a gap tool to reset the correct distance, although you should note that the ground electrode will eventually wear out, necessitating replacement. It’s the anode that has the post and the tongue, which is the center electrode and ground electrode. This node is found inside the cylinder housing when the spark plug is fixed into the motor. The anode is a small post covered by a metal tongue on a single end of the spark plug. The gap increases when the anode gets thinner. Faulty gaps can also form when there’s regular use that eats away part of the ground electrode. The engine heat causes the ground electrode to move. Dropping the spark plug on its ground electrode can cause the gaps to be misadjusted. That causes the ground electrode to move.
Handling and shipping are some reasons that lead to spark plugs getting bumped. It needs to be set to a specific width for the power generated to ignite the fuel. It’s the gap found between the center and ground electrodes, which is the post and tongue.
The gap on the spark plug depends on your lawnmower engine. This cycle repeats as the lawnmower continues working on your lawn. The action of the fuel pushing the pistons drives the wheel on a mower and generates electricity for the spark plug. It’s this fuel that pushes the piston, leading to the activation of the lawnmower blade. The plug creates a tiny open electrical charge inside the cylinder, which ignites the fuel.
#ARE SPARK PLUGS PRE GAPPED CODE#
Note that this is not a perpetual motion as some mowers use a battery, while others require you to pull a start code to generate the energy to start the motor.Īfter the motor powers on, it generates electricity to power on the spark plug. Spark plugs are devices that operate on the electricity produced by a running engine. Read on to learn more about the spark plug gap, what it is, and why the gap is essential when working with a lawnmower. That’s why it’s recommended to check the gap before installation. However, by the time the mowers get to the distributor, parts guy, or wholesaler, the spark plugs may not be where they were when leaving the manufacturer’s place. Most lawnmower spark plugs are pre-gapped before being released to the market. Most lawnmowers have engines that need this gap to function effectively. Lawnmowers are designed to make your work easier, but a slight change in the spark plug gap can affect how your machine functions.
