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
Engine braking is a method of slowing a vehicle down without using external braking mechanisms, such as friction brakes or magnetic brakes. Engine braking refers to the braking effect caused by the closed-throttle partial vacuum in petrol engines when the accelerator pedal is released.Full Answer >
A stroker engine has an increased piston stroke over the factory engine, which leads to more displacement and subsequently more torque. This is achieved by increasing the throw of the crankshaft, increasing the length of the connecting rod, and decreasing the compression height of the piston.Full Answer >
Engine knock can be caused by an incorrect air/fuel mixture within one or more cylinders. The knocking sound is the fuel burning unevenly and creating shock waves at the wrong times. The waves can damage the cylinder wall as well as the piston.Full Answer >
EcoBoost is a line of engines developed by Ford Motor Company, which they began manufacturing in 2010. EcoBoost engines use a combination of direct fuel injection, variable camshafts and a turbocharger to provide increased fuel efficiency without sacrificing anything in terms of torque, horsepower or overall performance.Full Answer >
