Advanced direct injection combustion engine technologies and by H Zhao

By H Zhao

Volume 2 of this two-volume set investigates diesel direct injection (DI) combustion engines, that are facing increasingly stringent emission laws world wide. Direct injection diesel engines are in general extra effective and purifier than oblique injection engines and as gas costs proceed to upward push DI engines are anticipated to realize in reputation for automobile purposes. exhaustive sections research light-duty and heavy-duty diesel engines, fuel injection platforms and after remedy platforms for DI diesel engines. the ultimate part addresses exhaust emission regulate options, together with combustion diagnostics and modelling, drawing on respected diesel combustion process study and development.

This is because the EGR is at high temperature, hotter than the intake air it replaces, which results in an increase in the overall intake charge temperature. 5 litre TDI Transit. The use of cooled EGR enabled further reductions in NOx and particulates compared to the previous hot EGR system. Cooling the EGR prior to mixing with the intake air lowers the combustion temperatures and increases the oxygen to fuel ratio. The higher flow of CO2 and H2O into the engine with cooled EGR increases the heatabsorbing capacity of the inlet charge; the lower inlet charge temperature generally reduces the combustion temperatures.

0 mm, which has power ratings of 74, 81 and 92 kW and peak torque of 240, 260 and 280 Nm at 2300 rpm. 4 mm. This engine has power ratings of 74, 88 and 110 kW with peak torques of 260, 280 and 320 Nm. 0 litres. This engine has power ranging from 93 to 110 kW and peak torque of 295 to 320 Nm. 0 mm to give a peak power of 135 kW and 400 Nm of torque at 1900 rpm (Automobil Revue, 2008). 8 Peugeot Peugeot is the second largest producer of diesel passenger cars in Western Europe. PSA produces two families of four-cylinder diesel engines in collaboration with Ford.

Engine performance was increased by more than 25%, giving a peak power of 115 ps combined with 250 Nm of steady-state torque and 280 Nm of transient over-torque. The fuel system also incorporated a novel combustion ‘knock’ sensor, an accelerometer attached to the cylinder block, to control pilot injection and thus combustion noise levels. 8 litre Duratorq TDCi engine. 8 litre Duratorq diesel engine (courtesy of Ford Motor Company). 8 litre engine was equipped with the Siemens (now Continental) 1600 bar ‘piezo’ common rail fuel system in conjunction with an enhanced EGR system and revised turbocharger matching.
