The D9, D11 and D12 diesel engines feature electronically controlled unit injectors. The injectors work at pressures up to 2 000 bar to produce the best possible fuel-to-air ratio at any load conditions. In combination with the 4-valve technology also used in the engines, this ensures an efficient flow of gases.
The electronically controlled unit injectors are perfectly matched to these high displacement engines. The result is reduced fuel consumption, low exhaust emissions, and outstanding overall performance.
