Engine Nissan ZD30

ZD30DDTi and ZD30DD are fairly well-known diesels manufactured by Nissan. The concern started designing them in the second half of the 90s, but started active production only in 1999 and 2000. At first, these units had a lot of flaws, so they were seriously criticized by the automotive community.

Over the years, Nissan has corrected the existing state of affairs by improving and significantly modifying the ZD30DDTi and ZD30DD. Motors with such names released after 2002 are not something scary and unpleasant for motorists. Redesigned ZD30s are high quality and functional diesels.

They were installed in minivans, SUVs and Nissan crossovers until 2012. After that, the production of the ICE in question was discontinued due to their moral and technical obsolescence.

Engine Nissan ZD30
The ZD30s concept is no different from their counterparts from the 00s of this century. Diesel engines are built on the basis of an aluminum block and a similar head with two shafts, gas distribution system “DOHC” and four cylinders.

The 3.0-liter diesel engine Nissan ZD30DDTi or simply ZD30 has been produced since 1999 and is installed on commercial vehicles, and we know it from Patrol or Terrano SUVs. This power unit exists in the Common Rail modification with its index ZD30CDR.

The cylinder block is cast from cast iron and consists of two parts:

  • block of cylinders;
  • crankcase of the main bearing caps (bottom of the cylinder block).

The crankcase of the main bearing caps increases the rigidity of the engine, which helps to reduce the noise level. Two balance shafts are used to reduce engine vibration. These shafts are located at the bottom of the cylinder block and rotate at twice the speed of the crankshaft. The balance shafts are driven by the intermediate gears of the timing drive mechanism and rotate in opposite directions in relation to each other.
