3 Facts About Engine Misfire for Future Pros with Careers in the Auto Industry
January 11, 2017
An automobile misfire is a little like a skip in the normal, healthy purr of the engine. The engine’s rotation hiccups, recovers, hiccups again, and continues on in this cycle. The result can mean many kinds of performance issues for cars, higher operating cost, and a fairly pricy repair bill.
When working in automotive careers, you will almost definitely run into a few misfiring cylinders when dealing with gasoline-powered cars. Here are a few facts you might find useful, or at least interesting, when faced with this situation.
Pros in Careers in the Auto Industry Know Misfires Are Typically Caused By One of Three Things
For an engine cylinder to fire correctly, the following must happen. First, a mixture of fuel and air must enter the cylinder. Next, the cylinder must provide a spark. The ignition of the air and fuel mixture causes a small explosion, which propels a piston. The force of this propulsion creates the torque an engine needs to move the automobile.
When there is a misfire, it usually means that one of three things has occurred. Either a cylinder’s air, fuel, or spark is missing, or too weak to cause the reaction needed for the engine to function correctly. Depending on which element is missing, this can indicate a problem with any number of parts. If you work on automobile repair, you may find that faulty fuel injectors, spark plugs, wiring, valves, or multiple other components can be responsible for engine misfire. All of these are involved in the process of delivering air and fuel to the cylinders, and then igniting them once inside.
Automobile Performance Is Affected In Multiple Ways by Engine Misfire
Misfiring cylinders affect engine performance in multiple ways. When working in careers in the auto industry, you can expect to see cars with misfiring cylinders shake fairly forcefully, stall, and have worse fuel efficiency. This means that people who continue to drive with this sort of issue will typically experience a higher cost for operating their vehicle.
Another common problem is that misfiring vehicles often emit more pollutants than normal, and there are laws regarding what vehicles are allowed to emit. Exceeding the limit can mean extra paperwork to clear the misfiring car with the government.
Most of your customers will likely understand the importance of getting a misfire fixed. For those who don’t, being able to explain the above issues may help you convince them just how important repairs can be.
Those With Careers in The Auto Industry Find that Misfire Repairs Can Get Quite Expensive
Depending on the cause of the problem, an issue with a misfiring cylinder can be fairly expensive. For something like a faulty spark plug, repair work should only cost somewhere in the range of $150 to $400. For something more serious, like a blown head gasket, costs can shoot up into the thousands of dollars.
If you work in automotive maintenance or repair after attending an automotive school in Montreal, you will be able to identify the kinds of issues that can cause a misfire. Be prepared for a strong reaction if the problem will be very expensive to correct, and be sure to be patient with customers who may be frustrated or confused that their vehicle—which may seem to be working okay—needs so much work.
Engine misfires can be caused by defects in many different parts, and result in multiple hits to a car’s performance. Be sure to be patient and understanding when dealing with customers who have this problem, as it can be quite expensive to fix.
