EFI Petrol Engine Test Bed Manufacturer,Supplier and Exporter in India
Product Code : EL-AELE-9380
Jlab Export is a leading EFI Petrol Engine Test Bed Manufacturer,and suppliers in India
A running engine on a stand is where diagnosis stops being theory. This test bed carries an EFI petrol engine and its transmission on a powder-coated tubular steel frame, with the instrumentation and accessories it needs to run. It is set up for teaching diagnosis, tune-up, fault finding and troubleshooting, and can later be connected to a modular dynamometer system.

Workshop Practice on a Running Engine
Compression testing usually comes first. Students disable the fuel injection and ignition and hold the throttle open. They then crank the engine with a Cylinder Compression Tester for Petrol Engine in each plug hole in turn. They then tee a Gasoline Fuel Injection System Tester into the fuel system and read the fuel pressure.
With the engine running, students check ignition timing and advance with a Digital Advance Timing Light. The exhaust goes to a Gas Exhaust Analyzer, which reads HC, CO, CO2, NO and O2 and works out the excess air coefficient. Fault codes stored by the engine control unit are read with an Auto Diagnostic Analyzer.
Frequently Asked Questions
What is checked first when an EFI engine cranks but will not start?
Check the three basics in turn: spark, fuel and compression. Look for a spark at a plug lead, then read the fuel pressure with the gauge and check that the injectors are being pulsed. Read any stored fault codes too. A faulty crankshaft sensor can stop both spark and injection at once.
What does EFI mean?
Electronic fuel injection. The engine control unit opens the injectors for a time it works out from its sensor signals, instead of a carburettor metering the fuel. That is why EFI diagnosis covers sensors, wiring and fuel pressure as well as the engine itself.
Why would a dynamometer be added later?
A dynamometer loads the engine and measures its torque, from which power is calculated. Without one, the engine runs with no external load, which suits diagnosis and tune-up work. The test bed is built so a modular dynamometer system can be connected as an upgrade.
Can ignition timing be adjusted on an EFI engine?
On most EFI engines the control unit sets the timing from its sensor inputs. The timing light confirms the base timing and shows the advance as the speed rises. Any adjustment possible follows the engine service manual.
Is the test bed ready to run?
Yes. It comes complete with the instrumentation and accessories to run, mounted with the engine and transmission on the tubular steel frame. Run it where the exhaust can be led to open air.
