: A Carnot cycle as an idealized thermodynamic cycle performed by a Carnot heat engine), illustrated on a TS (temperature T–entropy S) diagram. The cycle takes place between a hot reservoir at temperature T H and a cold reservoir at temperature T C. The vertical axis is the system temperature, the horizontal axis is the system entropy.
Hydraulic tappet. A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower.
In the extraction of petroleum (and other heavy-duty fluid handling contexts), a choke valve (or "choke") is an adjustable flow limiter that is designed to operate at a large pressure drop, at a large flow rate, for a long time. A choke is often a part of the "Christmas tree" at the wellhead . The most familiar choke design is a solid cylinder ...
The temperature range lies between the minimum and maximum operating temperature of the element. Elements can cover temperatures ranging from -15 °C to +120 °C. Elements may move in proportion to the temperature change over some part of the range, or may open suddenly around a particular temperature depending on the composition of the waxes.
An aftermarket fuel pump was a common modification made to the Ford's original spartan engine design. Even by the standards of the day, the engine was in many ways a half-manufacture when it came to thermal efficiency and other running characteristics which could lengthen the unit's life span and improve the car as a whole. The Model T ...
Air-cooled engine. Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator, coolant reservoir, piping and pumps.
Variable valve timing ( VVT) is the process of altering the timing of a valve lift event in an internal combustion engine, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical ...
These text files can ultimately be any text format, such as code (for example C#), XML, HTML or XAML. T4 uses a custom template format which can contain .NET code and string literals in it, this is parsed by the T4 command line tool into .NET code, compiled and executed. The output of the executed code is the text file generated by the template ...
