1 Connection – exhaust gas temperature sensor – diesel particulate filter 2 Pipes to diesel particulate filter differential pressure sensor 3 Diesel particulate filter and catalytic converter housing The diesel particulate filter of the 1.6L Duratorq-TDCi (DV) engine is downstream of the catalytic converter in the flow direction of the exhaust gases. Oxidation catalytic converter… Read More »
1 PCM 2 High pressure pump 3 High pressure chambers for high pressure generation 4 Fuel feed 5 Fuel metering valve 6 Fuel pressure sensor 7 Fuel rail 8 Solenoid valve 9 Injector needle The engine management system on the common rail injection system is capable of providing the optimum injection pressure for each operating… Read More »
1 Boost pressure solenoid valve 2 MAP sensor 3 Intercooler 4 Vacuum unit for variable turbine geometry 5 Turbocharger(s) 6 PCM 7 Vacuum pump On a variable turbocharger, the boost pressure is regulated by adjusting the guide vanes. This means that optimum boost pressure can be set for any operating condition. The boost pressure actual… Read More »
1 MAF sensor 2 PCM 3 Oxidation catalytic converter 4 Turbocharger(s) 5 EGR valve servo motor 6 Position sensor (integrated in servo motor) 7 Intercooler 8 EGR cooler 9 Intake manifold flap with servo motor (only in emission standard IV) By using turbochargers, the temperatures in the combustion chamber rise together with the compression and… Read More »
With the use of diesel particulate filters the remaining diesel particulate matter can be reduced by more than 99%. The storage capacity of the diesel particulate filter is limited. This means that the diesel particulates accumulated in the diesel particulate filter have to be removed periodically. This is achieved by burning off the diesel particulates… Read More »
An intake manifold flap is located in the air intake system which has the following functions: • Restricting the intake air for exhaust gas recirculation, • Closing the intake system when the engine is stopped, • Closing the air path via the intercooler while the regeneration of the diesel particulate filter takes place The intake… Read More »
