ACKNOWLEDGEMENT
This is to certify that the following term paper has been made by Anand Prakash of section B4912 on the topic “MULTI POINT FUEL INJECTION SYSTEM vs. CARBURETOR” under the supervision of our thermodynamics teacher Mr. Tukesh Kumar Soni sir.
I am greatly thankful to my teacher Mr. Tukesh Kumar Soni sir and sincerely pay my gratitude for providing me the guidance on the given topic.
ABSTRACT Carburetors have been around almost as long as the car itself. Its functionality can be explained as a device that delivers the correct amount of fuel to the engine according to the air that is forced through the engine by atmospheric pressure. The initial cost of a carburetor engine is almost five times cheaper than an electronic fuel injected one, although maintenance costs could perhaps set one back a bit. The clear advantage of a carburetor engine is that it is not restricted by how much gas is pumped from the fuel tank. This means that any modifications to the cam in an attempt to make the engine "breathe better" will allow the cylinders to pull more fuel through the carburetor resulting in a more dense explosive mixture in the combustion chamber. The end result… unrivaled power!
Multi-point fuel injection injects fuel into the intake port just upstream of the cylinder's intake valve, rather than at a central point within an intake manifold. MPFI (or just MPI) systems can be sequential, in which injection is timed to coincide with each cylinder's intake stroke; batched, in which fuel is injected to the cylinders in groups, without precise synchronization to any particular cylinder's intake stroke; or simultaneous, in which fuel is injected at the same time to all the cylinders. The intake is only slightly wet, and
