An engine's cylinder misfires when ignition occurs at the wrong time or not at all. Because the engine's moving parts must be in exact locations at the moment of the spark, incorrect timing often results in loss of power or a choppy ride.Know More
A car's gasoline engine converts fuel into mechanical energy through combustion. A mixture of gas and air are heavily compressed by pistons in the engine's cylinders. The spark plugs then ignite this volatile mixture, causing it to expand violently and move the pistons outward. The piston's back-and-forth movement is harnessed and used to move the vehicle.
But, with so many moving parts working in concert, any number of issues can destroy the precise timing necessary and create a cylinder misfire. While dirt and bad wires can affect the spark plug's ability to create ignition on time, other steps can also be compromised. For instance, bad injectors can change the composition of the fuel mixture, possibly creating a weak explosion that cannot properly move the piston. A broken piston, on the other hand, cannot move at all.
Fortunately, however, many of these issues can be avoided with preventative maintenance and keeping the engine properly tuned. Additionally, requesting a trouble-code scan annually can help detect problems before they become serious.Learn more about Car Parts & Maintenance
A proven method of removing a stuck car key is to have the driver gently rock the steering wheel back and forth while pulling the key out of the ignition, according to Popular Mechanics magazine. The rocking motion releases pressure on the ignition's locking pin.Full Answer >
An engine misfire occurs when one or more of the cylinders inside the engine doesn't fire correctly. It is caused by an interruption of the air-to-fuel ratio inside the combustion chamber in the cylinder.Full Answer >
Fix a cylinder misfire by determining where it is occurring, diagnosing the problem and replacing defective parts. Use an engine scan tool to help isolate the problem cylinder and likely cause of the misfire. The time to complete the process depends on the cause of the misfire.Full Answer >
The ignition temperature of a given substance is the measure of the minimum temperature at which the substance ignites, without the presence of an external spark or flame. Because of the fact that the material auto-ignites at this temperature range, it is also referred to as the substance's auto-ignition temperature.Full Answer >
