Explain engine hunting ?

Started on Wednesday 0 Replies

Variations in the engine rpm is known as engine hunting. These variations may happen due to abnormal condition of centrifugal governor which lies in fuel injection pump or may be due to fast idle…Continue

What does CRDI engine means ?

CRDI stands for common rail direct injection. These are diesel engines in which combustion takes place into main chamber directly. This chamber is located on the top of piston crown. These engines are used to overcome deficiencies of conventional engines. It uses common distribution pipe for all cylinders. See More

What is CNC programming and how it is useful ?

Programmers of CNC (Computer numerical control) write code for computing module that run on a CNC machines. These machines are extremely useful for giving shapes to the object and to cut the objects . Programmers are able to plot each and every step that includs how machines can develop these parts. Now a days almost all factories make use of CNC machines for creating various parts of machines. With advances in CAD technology it becomes easy to develop CNC machines.See More

Explain engine hunting ?

Variations in the engine rpm is known as engine hunting. These variations may happen due to abnormal condition of centrifugal governor which lies in fuel injection pump or may be due to fast idle control device. Quantity of fuel injection per cycle is fixed. But if it is varied then fluctuations occurs in engine rpm.…See More

SI engines working

In SI engines the burning of fuel starts by means of spark generated by the spark plug. This spark plug is located in the cylinder head of engine. Because of this these are also called as spark ignition engines. This type of engines are also known as Petrol or Gasoline Engines as they use fuel petrol or gasoline.See More

Why 4 valve engines are better than 3 valve engines?

3 valve engines are incorporated with 2 inlet valves and 1 exhaust valve whereas 4 Valve engines are incorporated with 2 inlet and 2 exhaust valves.Now a days, 4 valave engines are more preferred for car and bikes  because 2 inlet valves increases the area of air intake and thereby allows more air-fuel mixture to enter into the cylinder. Hence there will be efficient combustion.See More
