Advancing the injection timing has the following effects:\n\nIncreasing\n\n* Cylinder pressures/temperatures\n* Black smoke at peak torque\n* Emissions of oxides of nitrogen (NOx)\n* Black smoke at peak torque\n\nDecreasing\n\n* White smoke\n* Black smoke at tick over\n* Black smoke at designed rated power\n* Exhaust temperature\n* Brake specific fuel consumption\n* Hydrocarbons (HC)\n\nSetting the injection timing involves balancing power and emission requirements. The engine material tolerances limit the advance due to the increase in peak pressure/temperature.\n\n{{Page data\n| license = CC-BY-SA-3.0\n| keywords = diesel\n}}"}
