UINT NAME: FUNCTION AND OPEREATION OF VEHICLE PETROL INJECTION SYSTEM
UINT NO: 8
ASSIGNMENT: 1

TASK: 1 EXPLAN THE OPERATION OF MULTI POINT AND SINGLE POINT PETROL INJECTION SYSTEM USED ON MODERN FUEL INJECTED ENGINES
THERE ARE TWO TYPE OF FUEL INJECTION:
 Multi point fuel injection
 Single point fuel injection
 Sequential fuel injection
 Direct injection
 Carburetor

WHAT IS FUEL INJECTOR? It is the driver turns the ignition key on the energizes a relay that supplies voltage to the fuel pump The motor inside the pump starts to spin and runs for a few seconds to build pressure in the fuel system a timer in the pump will run until the engine starts Fuel is drawn into the pump through an inlet …show more content…
SINGLE POINT FUEL INJECTED:The point and location of fuel injection is one way to classify a gasoline injection system Single point injection is a known throttle body injection The air fuel mixed the throttle body Single-point injection uses a single injector at the throttle body it was introduced in the large aircraft engines Since the fuel passes through the intake runners it is called a wet manifold system The justification for single-point injection was low cost Many of the carburettors supporting components such as the air cleaner intake manifold and fuel line routing-could be reused OPERATION OF SINGLE POINT FUEL INJECTION:It is the single point injection is an only one injector air and fuel comes to the top Point and location of fuel injection is one way to classify a gasoline injection system A single point injection is a know throttle body injection (TBI) It is the fuel sprayed in to the top center of the intake manifold This system the injector is placed in the air-fuel passage going to the each cylinder and the petrol is sprayed into each intake port and toward each intake valve This type of technology is used in latest vehicles In this technology all modern systems are controlled electronically and it also ensures the quantity as well as quality of fuel are stetted accurately as per the suitable operating conditions of …show more content…

FUEL TANK: Fuel tank remains stable they are scourge remains in stable fuel Is it that phlutala in tactile fuel bag ate A fuel tank is a safe the fuel Though and storage tank for fuel may be so know the term is typically applied to part of a engine system in which the fuel is stored and propelled released in to an engine Fuel tank range

FUEL PUMP: Fuel tank remains stable they are scourge remains in stable fuel Is it that phlutala in tactile fuel bag ate A fuel tank is a safe the fuel Though and storage tank for fuel may be so know the term is typically applied to part of a engine system in which the fuel is stored and propelled released in to an engine Fuel tank range

FUEL FILTER: -A fuel filter is a filter in a fuel the fuel normally made in to cartridges containing a paper filter
FUEL LINE: -a fuel line is an in main part of fuel supply system in a use a maturely of a hard rubber and metal
CHARCOAL CANISTER: It carbon canisters are devices found in designed to decrease the amount of air pollution the vehicle creates while at the same time increasing its fuel efficiency Even when the is turned hydrocarbons are produced this in the form of fuel vapor rising in the fuel tank Carbon Canisters trap that vapor rather than allow it to escape the fuel tank feeding it back into the
