In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front.
Mercedes-Benz USA, LLC), which alleged the M272 engines are equipped with defective balance shafts gears which "wear out prematurely, excessively and without warning, purportedly causing the vehicles to malfunction, the check engine light to illuminate and the vehicle to misfire and/or stop driving." [5] The suit further alleged that Mercedes ...
In the case of highly supercharged or high compression multi-cylinder engines, pre-ignition can quickly melt or burn pistons since the power generated by other still functioning pistons will force the overheated ones along no matter how early the mix pre-ignites. Many engines have suffered such failure where improper fuel delivery is present.
Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
Animation of the 1-2-4-5-3 firing order MAN B&W 5S50MC 1,865 litre marine diesel engine. Straight-five engines are typically shorter than straight-six engines, making them easier to fit transversely in an engine bay. [1] They are also smoother than straight-four engines, [1] and are narrower than V engines [2] and flat engines.
The M177 was the first variation released in the Mercedes-AMG C63. [5] In contrast to the M178, this version of the engine uses wet-sump lubrication. In the C63 and GLC63 applications, the turbos are single-scrolled, whereas in E63 and S63 are twin-scrolled and different exhaust manifold.
Jeep, Chrysler, and Ram all have an oversupply problem, with the three brands having more than 100 days of supply at the end of summer compared to the industry average of 77, according to Cox ...
Atlas is a name for a family of modern inline piston engines for trucks from General Motors, used in the GMT355 and GMT360 platforms. The series debuted in 2002 with the Oldsmobile Bravada, and is also used in the Buick Rainier, the Chevrolet TrailBlazer and Colorado, the GMC Envoy and Canyon, the Hummer H3, Isuzu Ascender and i-370, and the Saab 9-7X.
