What is a single-point injection system?
The earliest and simplest type of fuel injection, single-point simply replaces the carburetor with one or two fuel-injector nozzles in the throttle body, which is the throat of the engine’s air intake manifold. For some automakers, single-point injection was a stepping stone to the more complex multipoint system.
What is a multi point fuel injection system?
The MPFI is a system or method of injecting fuel into internal combustion engine through multi ports situated on intake valve of each cylinder. It delivers an exact quantity of fuel in each cylinder at the right time.
What is multi point injection and how does it work?
The Multi-Point Fuel Injection system is a way of injecting the fuel in an internal combustion engine through multiple ports located on the intake valve of every cylinder the motor has. These ports work together to deliver the optimum quantity of fuel at the right time to every cylinder.
What are MPFI and TPFC systems?
MPFI stands for Multi Point Fuel Injection. These systems are sequential systems, in which injection is timed to coincide with intake stroke of each cylinder. TPFC stands for transient power fuel control system. In this type of systems constant choke carburetor is used.
What are the types of multi point fuel injection system Mcq?
In all, there are three varieties of MPFI units – Batched, Simultaneous, and Sequential. In the first kind of Multi-Point Fuel Injection system, the fuel is released to the cylinders by the ports in batches without getting their intake stroke together.
What are the three main types of injection system?
The main types of injection systems include pump-line-nozzle, unit injector, and common rail. Modern injection systems reach very high injection pressures, and utilize sophisticated electronic control methods.
