A timing chest or valve chest is a compartment on an internal or external combustion engine (e.g. gasoline or steam engine) which provides access to the tappets and valves. The chest is fitted with an inspection cover sealed with a gasket .
On engines that use a carburetor (e.g. in older cars, lawnmowers and power tools), a mechanical fuel pump is typically used in order to transfer fuel from the fuel tank into the carburetor. These fuel pumps operate at a relatively low fuel pressure of 10–15 psi (0.7–1.0 bar).
The process is very similar to a dental drill used by a dentist. These tools are able to dig faster, operate in a much higher temperature environment, deliver longer downhole life, and produce a better and straighter hole quality than a conventional mud motor. In many applications turbodrills can offer their customers significant cost savings ...
A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa ), [ 2 ] [ 3 ] petrol pumps (in Commonwealth countries), or gas pumps (in North America ).
Therefore, an accelerator pump is often used to briefly provide extra fuel as the throttle is opened. [12] When the driver presses the throttle pedal, a small piston or diaphragm pump injects extra fuel directly into the carburetor throat. [13] The accelerator pump can also be used to "prime" an engine with extra fuel prior to attempting a cold ...
Pumps - Pumps are another very popular turbomachine. Although there are very many different types of pumps, they all do the same thing. Pumps are used to move fluids around using some sort of mechanical power, from electric motors to full size diesel engines. Pumps have thousands of uses, and are the true basis to turbomachinery (Škorpík, 2017).
Delco ECU used in General Motors vehicles built in 1996. An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.
With early induction and ignition systems the compression ratios had to be kept low. With advances in fuel technology and combustion management, high-performance engines can run reliably at 12:1 ratio. With low octane fuel, a problem would occur as the compression ratio increased as the fuel was igniting due to the rise in temperature that ...
