Pinging in an engine is the result of the air and fuel mixture within an engine cylinder igniting incorrectly, explains Cars Direct. This may be caused by using gasoline with an insufficient octane rating, carbon buildup within the cylinder itself or improperly functioning spark plugs.Know More
When the fuel/oil mixture within an engine cylinder combusts, it normally does so in a progressive fashion rather than igniting all at once. This allows the force of the ignited fuel to provide controlled pressure on the piston, resulting in even thrust. If the ignition stutters or the gas ignites all at once, this creates a pinging sound and puts undue stress on the piston and cylinder, reducing performance and decreasing the life of the engine.
High-octane gas is designed to prevent preignition of the air/fuel mixture. Using a higher-octane gas than normal can reduce pinging. Carbon buildup on the cylinder wall can also cause improper ignition and pinging. All U.S. gasoline contains detergents. Adding a detergent to fuel often helps clear out accrued deposits; additive detergents can be found at automobile supply stores. Faulty spark plugs can also cause improper ignition. If pinging persists, visit a mechanic to verify all spark plugs are in proper working order.Learn more about Engine
Poor maintenance often leads to engine trouble. Neglecting to check the oil is a common cause of engine issues, according to ABC News as damage can occur from very low oil levels. Oil can also degrade substantially and stop providing adequate engine lubrication.Full Answer >
When the Check Engine light on a car is illuminated, it indicates the onboard diagnostic computer has detected a problem with the vehicle's emission system. The problem is due to a variety of conditions, ranging from a loose gas cap to serious engine problems.Full Answer >
A boxer engine is a four-stroke engine that has its pistons move simultaneously toward and away from one another on a horizontal plane. Each pair of pistons that lie next to each other has a motion that resembles a boxer throwing his fists, hence the name of the engine.Full Answer >
Driving a car with no oil in the engine, letting dirty oil stay in the engine and using ethanol gasoline are actions that can destroy a car's engine. General poor maintenance can destroy an engine over time.Full Answer >
