Diesel engines from India and Indian gensets for export are two separate supply chains. Engine makers build the engine; genset packagers fit an engine and an alternator to a base frame, canopy and control panel. Know which one you are buying from.
Rajkot is known for single-cylinder and small multi-cylinder engines, mostly for farm and pumping use. Gensets are built in several Gujarat cities by firms that buy in engines, alternators and controllers.
Who makes what?
Diesel engines made in Rajkot covers the engine side, including water-cooled and air-cooled types. Gensets made in Gujarat covers the packagers.
A genset firm may make its own canopy and fabricate its own base frame, yet still buy the engine and alternator. That is normal. What you need to know is which brands of engine and alternator go into your order, and whether the supplier can swap them without telling you.
What should a first order fix?
Write these down before you ask for quotes:
- The rating and whether it is prime or standby, with the frequency and voltage you run on.
- The cooling type, the starting method and any fuel or altitude limits at your site.
- The emission rules in your country, since a small engine that is lawful in one market may not be in another. See diesel engine emission standards.
- The alternator make and insulation class, the controller and the canopy finish.
- The test you expect before shipment, such as the load test explained in what a genset load test is.
Which checks protect you?
Ask for the engine and alternator serial numbers and photographs of the nameplates before loading. A genset sold as one rating may carry a different engine, so match the plate to the order.
A load test should run the set at stated percentages of its rated load and record voltage, frequency, oil pressure and temperatures. If you can, have the test witnessed or videoed. Writing a genset specification turns these points into a document a supplier can sign.
What about spares and warranty?
Engines fail where service is thin, so ask who supports the engine in your country. Agree a spares list for the first year, including filters, belts, injectors and seals, and make sure the engine and alternator warranties are written into the contract.
Packing matters too. Open gensets and loose engines need frames, sealed fluids and corrosion protection for sea freight. Cost depends on the engine brand, alternator, canopy and test, so a quote only makes sense against a written specification.
What can go wrong with the paperwork?
Customs and local rules for engines can be stricter than for general machinery. Some countries restrict used or reconditioned engines, and others require emission or noise approval before sale. The importer is normally the party responsible, so confirm the position with your customs broker or regulator before shipping.
Ask for a commercial invoice that lists the engine and alternator serial numbers, a packing list that matches the crates, and the test certificate for each set. The document pack your broker will ask for lists what clearance normally needs.
If you plan to fit engines locally into your own machines, engine kits for local assembly explains the option and what to document.
One more check applies to both. Ask for photographs of the nameplate at the point of loading, because the plate is the only thing customs and your own regulator will see.
