1. Descripción general del producto
The Mitsubishi 4D56U y 4D56HP are upgraded 2.5L turbocharged diesel engines based on the classic 4D56 platform. Both feature aluminum alloy cylinder heads, inyección directa de riel común (CRDi), and are used in various pickup trucks and SUVs globally. The 4D56HP (“High Power”) variant typically uses a DOHC 16-valve diseño con variable geometry turbocharging (VGT).
These engines are known for reliability, fuel efficiency, and wide parts compatibility, making their cylinder heads highly sought after in both repair and performance markets.
