What is engine assembly?Origin and Background of the Engine Cylinder Head
Technical Upgrades and Iterations (from MR20DE to MR20DD): Compared to the older MR20DE with multipoint fuel injection (MPI / Port Injection), the “new” MR20 (typically designated as MR20DD)
is a 2.0L inline-four-cylinder engine that Nissan widely promoted in the mid-to-late 2010s.
Key Changes to Cylinder Head Design:Direct Injection (DIG): The new MR20DD cylinder head directly integrates high-pressure direct injection nozzle sockets and the high-pressure fuel pump (HPFP) drive mechanism.
The intake manifold geometry has been redesigned to improve the tumble ratio.
Twin C-VTC (Dual Variable Valve Timing System for Intake and Exhaust): Upgraded to dual variable timing control for both intake and exhaust valves, further optimizing low-rpm torque and fuel economy.
High-Pressure, High-Temperature Design: The cylinder head is constructed from high-strength, high-thermal-conductivity aluminum alloy, and the cooling jacket’s
flow path has been meticulously optimized using fluid dynamics to withstand a higher compression ratio (11.2:1) and combustion chamber pressure.
Our products are exported to various parts of the country, and the customers we have worked with have received unanimous praise. The company has invested over 20 million yuan in high-end remanufacturing equipment imported from abroad and a first-class production team in the country. Our warehouse has a total area of over 8000 square meters, with scientific management and sufficient supply of goods.
