(Direct Ignition COmman Rail)
This system is used in most latest cars of tata motors. The cars using this technology includes safari dicor, indica dicor, indigo dicor, grande dicor.
This system uses a special single rail through which the fuel is taken to the combustion chamber of an engine. This helps to supply the engine an equal amount of fuel to each cylinder.
During engine operation, hot exhaust gases blow out through the exhaust valve opening into the exhaust manifold. The exhaust manifold and the connecting turbine route these gases into the turbine housing. As the gases pass through the turbine housing, they strike on the fins or blades on the turbine wheel. When the engine load is high enough , there is enough gas flow and this makes the turbine wheel to spin rapidly. Turbine is connected to the compressor housing. Centrifugal force throws the air outward. This causes the air to flow into the engine cylinder at high pressure. This enhances engine efficiency
