What does injection pump stand for?
for more unique definitions from across the web! What does INJECTION PUMP mean? An Injection Pump is the device that pumps diesel (as the fuel) into the cylinders of a diesel engine. Traditionally, the injection pump is driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft.
How noisy should a fuel injection pump be?
Fuel injectors do make a noise, but it would usually be described as a “buzzing” rather than a “ticking”. If you could figure out a way to remove the injectors from the engine but keep them hooked up to the fuel rail and electrical connectors, aim them at a container to catch the gas, and get them to go into inject mode while the fuel pump was running, then you’d know for certain.
What are the two types of mechanical injection pump?
These are basically low-pressure type of fuel pumps, sometimes also used for high pressure, whose main work is to transfer the fuel from tank to the fuel bowl of the spark ignition engine.

What is MFI fuel jet?
MFI fuel bypass jets control the fuel mixture to the engine. These jets divert a certain amount of fuel away from the engine and back to the fuel tank, which is useful for controlling the overall fuel flow to the engine. Additionally, high-speed bypass jets come on when the engine reaches a certain engine speed.
What is a fuel pump?
Hoses or tubing to carry the fuel from one component to the other. A mechanical fuel pump sized for the type of fuel, power level, and engine RPM range. Injector hoses, distribution block, and injector lines to feed the injector nozzles. Injector nozzles to inject the fuel into the air stream going into the engine.
What is a jet in fuel injection?
A jet restricts the flow and controls the amount of fuel delivered to the engine. Changing the size of the main bypass jet is one way to tune a mechanical fuel injection setup, as a bigger jet leans the engine while a smaller jet richens the engine.
How big is a fuel pump?
Fuel pump size is important. Normal installations involve a fuel pump about 25- to 50-percent larger than the engine demand. Tuning is simple by controlling the amount of excess fuel bypass back to the fuel supply. In addition, the fuel pump should be fed with an adequate supply line to avoid inlet cavitation.
What is barrel valve?
A barrel valve or metering valve controls the appropriate amount of fuel for starting, part-throttle, driving, and stopping. A barrel valve is also used to throttle the fuel for part-throttle driving. Most barrel valves have a very simple spool or metering cylinder inside of the valve for controlling the fuel flow.

How does an injection pump work?
Traditionally, the inject ion pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft. It rotates at half crankshaft speed in a conventional four-stroke diesel engine.
Why are mechanical pumps being phased out?
Mechanical pumps are gradually being phased out in order to comply with international emissions directives, and to increase performance and economy. From the 1990s an intermediate stage between full electronic control were pumps that used electronic control units to control some of the functions of the rotary pump but were still mechanically timed and powered by the engine. The first generation four and five cylinder VW/Audi TDI engines pioneered these pumps before switching to Unit Injectors. These pumps were used to provide better injection control and refinement for car diesel engines as they changed from indirect injection to much more efficient but inherently less refined direct injection engines in the 1990s. The ECUs could even vary the damping of hydraulic engine mounts to aid refinement. BOSCH VP30 VP37 VP44 are example pumps. Since then there has been a widespread change to common rail diesel systems and electronic unit direct injection systems. These allow for higher pressures to be developed, and for much finer control of injection volumes, and multiple injection stages compared to mechanical systems.
How do diesel pumps work?
Earlier diesel pumps used an in-line layout with a series of cam-operated injection cylinders in a line , rather like a miniature inline engine. The pistons have a constant stroke volume, and injection volume (i.e., throttling) is controlled by rotating the cylinders against a cut-off port that aligns with a helical slot in the cylinder. When all the cylinders are rotated at once, they simultaneously vary their injection volume to produce more or less power from the engine. Inline pumps still find favour on large multi-cylinder engines such as those on trucks, construction plant, static engines and agricultural vehicles.
Can diesel be injected into skin?
This is a good reason to take great care when working on diesel systems; escaping fuel at this sort of pressure can easily penetrate skin and clothes, and be injected into body tissues with medical consequences serious enough to warrant amputation.
