4 Stroke Petrol Engine
Product Code : LSK-E-10490
4 Stroke Petrol Engine (SKU LSK-E-10490) is a single-cylinder, four-stroke petrol engine adapted for education and built to run on the Small Engine Test Set, so students can load and test a real spark-ignition engine. It suits IC engine labs in mechanical and automobile engineering departments, polytechnics and technical institutes. From Ambala, India, Science Lab Supplies prepares quotations for the engine and dispatches it to colleges, training institutes, tender contractors and distributors.
Specifications
The table gives each specification of the petrol test engine on a separate line. Put simply, it sits on a sturdy precision bed plate whose dowels and slots align it with the dynamometer test set, and it comes with an exhaust thermocouple, a dynamometer half-coupling, essential hoses and fittings, and a removable fuel tank.

Applications and Experiments for the 4 Stroke Petrol Engine
Coupled to the test set dynamometer, the engine is run at different loads so that students can measure torque, work out brake power and compare their results with theory. The exhaust thermocouple adds exhaust temperature, which feeds heat-balance calculations when further ancillaries are used.
- B.Tech/B.E. mechanical: performance test of a four-stroke spark-ignition engine.
- Diploma automobile engineering: petrol engine operation and testing, set against the two-stroke cycle of the Two-Stroke Compression Ignition Engine Model.
- Comparing petrol and diesel engine performance on the same test bed.
- Propulsion lessons: contrasting a piston engine with intake, compression, combustion and turbine stages on the Educational Turbojet Engine Trainer.
Petrol is highly flammable: keep the removable tank in a fuel locker when not in use, and run the engine only with exhaust extraction and trained supervision.
Standard Scope of Supply
The engine is supplied on its precision bed plate with the exhaust thermocouple, the half-coupling for the dynamometer, the colour-coded fuel tank with self-sealing couplings, and all essential hoses and fittings. The Small Engine Test Set can be added to the same quotation as a separate line.
Packing, MOQ and Lead Time
Quotations can be for this engine alone or for a full test bench with its test set and ancillaries, and each one gives the packing, delivery time and price for what you list. The diesel engine can be added for comparison.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Name the engine and whether you already own the test set when you write through the contact page, or place it in the enquiry cart; buyers of engineering lab equipment in India by tender can use the lab tender page.
Frequently Asked Questions
Does the engine work without the Small Engine Test Set?
It is built for use with that test set: the bed plate locates on its bed and the half-coupling links to its dynamometer. The test set is quoted separately as its own line item.
How is the fuel tank connected?
The colour-coded tank uses self-sealing couplings, so it connects and disconnects quickly with minimum loss or spillage of fuel. It can be removed for filling, and removing it also prevents unauthorised use.
Can it be swapped with the diesel engine?
Yes. Dowels and slots on the bed plate align the engine accurately with the dynamometer test set, which keeps the time spent replacing one engine with another to a minimum.
Who supplies the 4 Stroke Petrol Engine?
Enquiries for this spark-ignition engine go to Science Lab Supplies in Ambala, India, whose quotation can cover the engine alone or add the test set, fuel gauge and calorimeter as separate lines.
