Features of i-CTDi and i-DTEC engines
i-CTDi and i-DTEC engines have 4 cylinders and 16 valves. The engine block is made of aluminum and the cylinder liners are made of cast iron. This reduces the weight of the motor and allows it to heat up more quickly. The cylinder head is made of aluminum. The valve control unit works with the help of a chain. All models are equipped with a variable geometry turbocharger.
