describing the motion of the intake and exhaust valves in relation to the piston moving up and down in the cylinder. This month we'll examine the parts, collectively known as the "valvetrain ...

Superior Air Parts' service bulletin pertains to cylinders rebuilt or overhauled with Superior intake valves found on Continental 470-series engines, which are used to power a variety of aircraft ...

As a vehicle's engine operates, the intake and exhaust valves open and close rapidly while the pistons move up and down in the cylinder. These mechanical actions require a constant supply of hot oil ...

Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need ...

Big cylinder heads with properly sized ports and larger valves along with more efficient intake manifolds and headers are all parts intended to minimize these flow losses. The problem with big ...

One of the critical parts of an engine that enables the creation of energy is the valvetrain. The valvetrain is the mechanism that controls the intake valve, which lets the oxygen and fuel into ...

The anticipation of Ford Racing Performance Parts' (FRPP) new Three-Valve intake manifold has been huge, to say the least. When rumors first started about it, a buzz quickly grew on the Internet ...

The 300hp 4.6-liter engine found under the hoods of S197 Mustangs is certainly the most potent bullet of any GT. The bottom end is virtually identical to the previous generation's modular engine ...

Separating the crankcase from the intake manifold ... a replacement interval. The valve is an inexpensive, easily replaced example of the dozens of parts that can elicit a check engine light ...

Valve overlap—that crucial interval when both the intake and exhaust valves are open, expressed in degrees of crankshaft rotation—is typically a fixed parameter and always a compromise.

The intake valve for both the 2.7- and 3.0-liter EcoBoost features part number JT4E-6507-AB in the automaker's parts system. Both engines are part of the Nano family, which came out for the 2015 ...
