Cylinder drain cocks can be manual or automatic. One type of automatic drain cock contains a rolling ball which allows water to pass, but blocks the flow of steam. [3] The ball occupies a horizontal cylinder slightly larger than the ball, allowing liquid water to flow past the ball.
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.
Siamesed cylinders are engine cylinders arranged in such a way that they have no channels between them to allow water or other coolant to circulate. [ 1 ] [ 2 ] Cylinders are generally arranged in this manner when the engine block is of limited size or when stability of the cylinder bores is of concern, such as in racing engines. [ 3 ]
It’s even possible to get a turbo 2.0 L 4-cylinder in some models. “The beauty with Lexus products is they are essentially Toyotas,” Holubetz said. “A lot of their drivetrains are built on ...
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.
The Grenadier sports respectable street cred, pairing a 3.0-liter six-cylinder engine from BMW with an eight-speed ZF gearbox. (Ratcliffe sourced the powertrain prior to forming the F1 partnership ...
Besides leakage noise, indicated percentage of leakage will sometimes vary with regulator pressure and orifice size. With 100 psi and a .030" orifice, a given cylinder might show 20% leakage. At 50 psi, the same cylinder might show 30% leakage or 15% leakage with the same orifice. This happens because leakage flow is almost always very turbulent.
