Hyundai D6CCDue to various factors affecting the power of the Hyundai engine, the air consumption is not the same. The turbocharger is a reliable, well-proven tool for precise air flow control. To obtain the required power, it is necessary to supply a strictly metered amount of fuel to a certain amount of air. To reduce the amount of toxic components in the exhaust gas, the developers of the D6CC engine increase the amount of air in the air-fuel mixture. Ideally low exhaust gas emissions are achieved when 20% more air than fuel enters the combustion chamber. It is possible to take into account all these factors, as well as reduce fuel consumption today, using high pressure electronic fuel injection.
