Mitsubishi 4b4 engine is assembled in China by importing some parts, so it is not a pure imported engine.
4b4 is a 1.5t turbocharged engine, which integrates many advanced technologies. This engine is equipped with dual fuel injection system, low inertia turbocharger, high durability piston, ultra-high precision crankshaft and ultra-high precision cylinder head and cylinder block from Ishikawa Island, and is produced by fully traceable intelligent automatic assembly line. This engine is also equipped with Mitsubishi's own electric exhaust pressure reducing valve made in mitsubishi electric, which reduces the amount of exhaust gas entering the turbine with the increase of engine load, thus preventing the danger of excessive turbine pressure. The cylinder head and cylinder block of the engine are made of aluminum alloy.
The turbine of this engine adopts Ishikawa Island turbine, which has a small diameter and can rotate and supercharge quickly in a low speed range, which can obviously inhibit the turbine hysteresis. The pressure of the turbine is about 1.5BAR, the maximum speed is 24, rpm, and the torque can increase rapidly in the low speed range. And the exhaust manifold is integrated in the cylinder head, which can quickly make the engine reach the working temperature, improve the thermal efficiency and reduce the formation of carbon deposits.
this engine retains mivec variable exhaust valve lift technology. Through the continuous and accurate control of the exhaust valve, the engine can always be in an efficient working state, reduce fuel consumption and emissions, and improve the service life of the engine.
