A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines.

CO 2 emissions and fuel consumption have been cut by 13% compared to the predecessor engine, while peak torque and peak power have been increased by up to 33%. Opel’s engineers selected a central direct-injection fuel system for optimum fuel efficiency and minimal emissions. The all-new 1.6-liter, The new engine family comprises a 1.6

They found that at all loads, GDCI was remarkably clean, with the potential for no aftertreatment for NO x and particulate emissions. Very low fuel consumption, NO x , and PM emissions were measured. A practical powertrain system with robust PPCI combustion is needed, including injection, valvetrain, boost, and exhaust subsystems.

This configuration demonstrates how off-highway manufacturers can potentially reduce the engine size for applications that currently require an engine at or slightly above the US EPA’s Tier 4 or Euro 5/6 emissions threshold of 75 hp (56 kW). —Aziz Aghili, president of Dana Off-Highway Driveline Technologies.

Despite its efficiency, the Golf TSI BlueMotion with the 85 kW / 114 hp downsized 999 cc EA211-series engine reaches 100 km/h in 9.7 TSI (81 kW / 110 PS) with four cylinders: lower weight; reduced CO 2 emission; improved driving dynamics. The weight was reduced by 10 kg (to 89 kg / 196 lbs), and CO 2 emissions were reduced by 10%.

liter EcoBlue diesel engine—the first in a new range of diesels that will offer optimized fuel efficiency and reduced CO 2 and NO x emissions. Ford says that the new engine will comfortably meet future European emissions requirements by using Ford’s first standardized selective catalytic reduction system.
