Hyundai

Hyundai diesel vehicles primarily use Common Rail Direct Injection (CRDi) technology, which stores high-pressure fuel in a "common rail" before injecting it into the combustion chamber. This system allows for precise electronic control over fuel timing and quantity, resulting in better fuel efficiency, higher torque, and lower emissions compared to older mechanical systems. Modern Hyundai diesel engines, such as those from the R-series or D-series, can operate at extreme pressures of up to 2,200 bar
