In this article we describe the platform, the material, the specifications, the applications and the points a buyer should confirm before an order.

Platform and Material of the Dongfeng M9T Cylinder Block

The page states that the engine is based on the fourth-generation M9 platform of the Renault-Nissan Alliance. The cylinder block is cast iron. The stated design goals are high reliability, low fuel consumption and reduced noise. The buyer should confirm the exact engine variant, the bore and stroke, the deck height, the main bearing size and the mounting points, because the M9T name can cover several configurations. The page gives the platform and the material but not a full drawing, so the application list and the engine number should be checked before the order.

Specifications and Vehicle Applications

The page gives product dimensions of 30.56 by 42.7 by 38 cm and a product weight of 54.8 kg. The applications listed are light trucks, pickup trucks, light commercial vehicles and premium SUVs and MPVs. A cast iron block is used where strength and durability are important, and the buyer should confirm the machining state, the cylinder liner type, the surface finish and the cleaning requirement. The buyer should also confirm the accessory holes, the oil gallery plugs and the core plugs, because a missing or a different plug can stop the installation.

Quality and Buyer Checklist

The page presents the company as a manufacturer of automobile engine parts that adopts intelligent manufacturing solutions, with technical strength, quality assurance and investor relations sections. For an order, the buyer should confirm the material, the casting grade, the machining tolerance, the inspection report and the packing. The buyer should also confirm the sample approval and the first article inspection. The page does not list a price, a minimum order quantity or a delivery lead time for this block, so those points should be requested with a quotation. A dimensional report and a pressure test report are the practical way to check the block before the bulk order.

An engine cylinder block carries the cylinders, the crankshaft and the main bearings, so the dimensional accuracy and the material soundness are critical. The buyer should ask for the bore diameter, the cylinder liner protrusion, the main bearing bore and the deck flatness, and should confirm the pressure test for the water and oil galleries. The casting should be free of porosity, cracks and sand inclusion in the critical areas. A first article report with those measurements is more useful than a general catalog page.

Customization and Contact

The page states that Ruifeng offers professional customization of engine cylinder blocks and heads, with a one-stop service from drawings to finished samples. The contact details shown on the page are email jyb@hbsgt.com and telephone +86-318-3312629. The address is No. 69, Mount Taishan East Road, Shenzhou, Hebei, China.

The Dongfeng M9T Cylinder Block described above is therefore a cast iron block based on the fourth-generation M9 platform, with a listed size of 30.56 by 42.7 by 38 cm and a weight of 54.8 kg. The page gives the platform, the material and the applications, while the exact engine variant and the machining detail should be confirmed with the supplier. A drawing review and a dimensional report are the clearest way to approve the block before the order.
