The 2.5-liter diesel engine Nissan YD25DDTi or YD25 has been produced since 1998 and is installed on the most popular minibuses, pickups and SUVs of the company. This motor replaced the CD20 and TD25 on some cars. The cylinder block here is an in-line 4-cylinder, cast iron, with a cylinder diameter of 89 mm. Inside the block there is a crankshaft with a piston stroke of 100 mm, and the length of the connecting rods is 154.5 mm. All this gives 2.5 liters of working volume.
