Common rail technology for Kia´s diesel debut
The first Kia passenger car to be available with a diesel engine, the new Cerato range offers customers a choice of not just one diesel, but two, plus two gasoline engines, and five-speed manual or four-speed automatic transmissions - depending on model.
Both the new Kia diesel engines feature a common rail high pressure fuel injection system. Rather than relying on indirect injection of the air and fuel mixture, the common rail engine delivers vaporised fuel directly to the cylinders (direct injection), enhancing fuel efficiency to an optimal level. High-pressure fuel produced by the fuel pump is sent to an accumulator. The state of the engine is constantly analysed and monitored by the ECU, which precisely controls timing, quantity, and pressure before injecting fuel into the cylinders.
