Fuel Injection Trainer - Multi Point EFI System Manufacturer,Supplier and Exporter in India
Product Code : EL-AELE-9383
Jlab Export is a leading Fuel Injection Trainer - Multi Point EFI System Manufacturer,and suppliers in India
A working multi point fuel injection system for a four-cylinder engine is set out on this trainer, using original components on a display board. The board stands on a wheeled floor frame of powder-coated electro-galvanized steel. A signal generator varies the sensor signals, a meter shows each one, and the open, programmable ECU connects to a PC.

How a Multi Point System Works
In a multi point system each cylinder has its own injector, placed in the intake port just ahead of the inlet valve. An electric pump feeds fuel to a common rail, and a regulator holds the rail at a set pressure. The ECU reads the engine sensors and decides how long each injector stays open. That opening time, the pulse width, sets the fuel delivered on each cycle.
Practicals on the EFI Trainer
Students start by tracing the system on the colour-coded chart and finding each part on the board. They then use the signal generator to copy a cold start or a wide-open throttle and watch the meters and the PC data show how the ECU responds. At the input/output panel they probe sensor voltages and injector duty cycle with a Hand Held Tune-Up Analyzer.
For the fuel delivery side, the class can compare the board with the Fuel Supply System Petrol MPFI Type working model. That model has a motorised pump, fuel rail and injectors. Advanced groups can change ECU settings from the PC and log the effect on the meters.
Frequently Asked Questions
What is the difference between MPFI and single point injection?
Single point, or throttle body, injection uses one or two injectors above the throttle for all cylinders. Multi point injection gives every cylinder its own injector at the intake port, so the fuel is shared more evenly. This trainer shows the multi point type on a four-cylinder layout.
Can students create different engine conditions?
Yes. The signal generator alters the sensor signals to copy different engine conditions, and the meter on that signal shows the change at once. Teachers use this to show how a wrong sensor reading changes what the ECU does.
Does the trainer connect to a computer?
Yes. The ECU is open source and programmable and connects to a PC. From the PC, students can program the ECU and view the system data while they change sensor conditions on the board.
How does it differ from the EFI Petrol Engine Test Bed?
The test bed carries a complete running EFI petrol engine and transmission for diagnosis and tune-up work. This trainer lays the MPFI parts and wiring out flat on a board with a signal generator, so every sensor and ECU connection can be reached and studied.
Is a wiring diagram provided?
Yes. A colour-coded schematic of the EFI system and circuit sits under a polycarbonate screen on the trainer. The wiring panel also brings out the input and output connections of the sensors and the ECU.
