How tight should the cylinder head of Nissan ZD30 engine be torqued?
1 Answers
Nissan ZD30 engine cylinder head should first be torqued to 5 kg, then tightened an additional 90 degrees, approximately reaching around 7 kg. Working principle of ZD30 engine: The ZD30 utilizes a turbocharged intake system, effectively enhancing engine power. Its dual overhead camshaft design with 16 valves allows for larger and more precise intake and exhaust volumes. It employs Bosch's third-generation high-pressure common rail injection system, with a maximum fuel injection pressure of 1600 bar. The 9-hole injector nozzles have a diameter of only 0.123mm, capable of performing five injections within a single stroke. Advantages of diesel engines: Diesel engines offer the benefits of high torque and excellent fuel economy. The working process of diesel engines shares many similarities with gasoline engines, with each operating cycle also going through four strokes: intake, compression, power, and exhaust.
