Description
The (TUR) MITSUBISHI 4D56T I4 DOHC is a turbocharged 2.5-litre diesel engine that has powered a wide range of Mitsubishi vehicles, including the Challenger PB series (2011–2015). Known for its balance of durability and performance, this engine features a 16-valve double overhead camshaft (DOHC) design. This improves airflow and efficiency compared to earlier single-cam versions.
One critical component in this setup is the inlet manifold assembly (PG799), designed to fit seamlessly with the Challenger PB’s 4-door SUV configuration. The inlet plays a vital role in directing air into the combustion chambers. Ensuring optimal mixing with fuel for efficient combustion. In turbocharged engines like the (TUR) MITSUBISHI 4D56T I4 DOHC, the inlet must withstand higher pressures and temperatures. Making reliability and precision engineering essential.
