Techron is a patented fuel additive developed by Chevron Corporation and sold in its fuel operations (including Texaco and Caltex).It contains a polyether amine-based detergent, which is purported to dissolve deposits in automotive engines and prevent them from building up.
Engine knock is caused by a cool flame, an oscillating low-temperature combustion reaction that occurs before the proper, hot ignition. Lead quenches the pyrolysed radicals and thus kills the radical chain reaction that would sustain a cool flame, preventing it from disturbing the smooth ignition of the hot flame front.
A ceramic engine is an internal combustion engine made from specially engineered ceramic materials. Ceramic engines allow for the compression and expansion of gases at extremely high temperatures without loss of heat or engine damage. [1] Proof-of-concept ceramic engines were popularized by successful studies in the early 1980s and 1990s.
The National Highway Traffic Safety Administration is investigating reports of alleged engine failures in GM's 6.2-liter L87 V-8, an engine used in a wide variety of trucks and SUVs.
When small pieces of metal chip off gears in the aircraft due to wear, it can generate dangerous metal debris that can damage engines. The gearbox has been under scrutiny in various Osprey ...
The U.S. National Highway Traffic Safety Administration is upgrading a probe into Ford's BlueCruise technology following reports of collisions.
If detonation is allowed to persist under extreme conditions or over many engine cycles, engine parts can be damaged or destroyed. The simplest deleterious effects are typically particle wear caused by moderate knocking, which may further ensue through the engine's oil system and cause wear on other parts before being trapped by the oil filter.
An illustration of several key components in a typical four-stroke engine. For a four-stroke engine, key parts of the engine include the crankshaft (purple), connecting rod (orange), one or more camshafts (red and blue), and valves. For a two-stroke engine, there may simply be an exhaust outlet and fuel inlet instead of a valve system.
