Engine management system (MPI)
The Engine management system (MPI) (Product Code: SLE/ATE/28) is a mobile demonstration stand for practical and laboratory training on a gasoline injector engine management system with multipoint petrol injection. Students can watch fuel delivery and ignition in action, take electrical measurements at built-in connectors on the circuit diagram, and practise fault finding and control unit diagnostics through a 16-pin socket. It suits automobile engineering diplomas and degrees, ITI motor mechanic trades and service technician courses. The stand is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, an engineering lab equipment manufacturer.
Specifications
| Parameter | Detail |
|---|---|
| Purpose | Practical and laboratory training/testing of a gasoline MPI engine management system |
| System | Gasoline injector engine management system with multipoint petrol injection, installed in the upper part of the stand |
| Stand | Mobile, on four wheels; closed structure with internal wiring not visible |
| Size | 1860 × 1450 × 700 mm |
| Power | Network power supply (220/12V) and a 12V battery |
| Fuel system monitoring | Amount of injected fuel, fuel supply system and fuel pump pressure; fuel pump and distribution system built so the fuel flow distribution can be seen |
| Engine speed | Adjustable crankshaft rotation speed |
| Air intake | Adjustable air flow in the intake manifold for demonstrating the air mass flow and air temperature sensors |
| Mixture control | Air/fuel mixture can be altered with an O2 sensor signal simulator |
| Ignition | Ignition system and spark plugs mounted for visual monitoring; high voltage circuit measurements possible; flame intensity measured by adjusting the ignition gap |
| Operation check | Injector and spark operation checked in the plug sequence 1, 3, 4, 2, with inspection of each sensor |
| Electrical measurement | Built-in voltmeter; principal electrical circuit diagram of the MPI system with built-in measurement connectors; electrical parameters of any component measurable; waveforms checked against RPM |
| Fault simulation | 15 system errors simulated by disconnecting plugs from connectors |
| Diagnostics | Control unit diagnostics via 16-pin diagnostic socket; reading and deletion of detected errors; system parameter control; control unit coding/configuration |
| Included with the stand | Exam/practical work simulation terminal (able to simulate not less than 10 different system errors), automobile oscilloscope, diagnostics equipment |
Typical Use
A typical lab session starts with the system running normally: students vary crankshaft speed and intake air flow, watch the fuel distribution and spark plugs, and capture injector and ignition waveforms on the automobile oscilloscope to see how they change with RPM. The instructor then uses the O2 sensor signal simulator to push the mixture rich or lean, so learners can see how the engine management system responds to sensor input and why oxygen sensor faults affect fuelling.
Fault-finding practice follows. Plugs are pulled to create any of the 15 built-in errors, and trainees work only from the circuit diagram, measurement connectors and scan tool — since the internal wiring is hidden, they must diagnose by measurement rather than by tracing wires, exactly as on a real vehicle. Codes are read and cleared through the 16-pin socket, and the exam terminal allows assessed practical tests. This makes the stand strong lab equipment for technical institutes preparing technicians for modern petrol injection service work.
Manufacturer

Frequently Asked Questions
How many faults can be simulated?
The stand simulates 15 system errors by disconnecting plugs from connectors. The included exam/practical work simulation terminal can simulate not less than 10 different system errors for assessments.
What diagnostic tools come with it?
An automobile oscilloscope, diagnostics equipment and the exam terminal are included. Makes and models of these tools are not stated in the listing — contact us if your specification names them.
Can students read and clear fault codes?
Yes. Control unit diagnostics run through a 16-pin diagnostic socket, with reading and deletion of detected errors, system parameter control and control unit coding/configuration.
What power does the stand use?
It is equipped with a network power supply (220/12V) and a 12V battery.
Why is the wiring hidden?
The stand has a closed structure so trainees diagnose faults by measuring at the connectors on the circuit diagram, as they would on a vehicle, rather than by following visible wires.
How much floor space is required?
The training stand measures 1860 × 1450 × 700 mm and moves on four wheels, so it can be positioned where a group can gather around it.
Is installation or instructor training offered?
