At the US Department of Energy’s (DOE’s) Annual Merit Review meeting in Washington, DC last week, Michael Ruth from Cummins noted that the DOE program target for the project is a fuel economy (CAFE) target of 26 mpg (9.05 Fuels Lubr. Diesel Emissions Engines Fuel Efficiency' Earlier post.). l/100 km) for a vehicle of that size.

The Volvo Car Corporation is introducing a new, downsized engine range consisting solely of four-cylinder gasoline and diesel engines. It covers the range from high-power and -torque variants to fuel-efficient derivatives. The new powertrains are also up to 90 kg lighter than the present ones and fuel economy is improved by up to 35%.

Simulation study finds Miller version of Scuderi engine can deliver twice the BMEP as naturally aspirated version, theoretically enabling 50% downsizing while maintaining performance. Applying the Miller cycle to the Scuderi engine (right) entails downsizing of the compression cylinder. Source: Scuderi. Click to enlarge.

The Advanced Elastoval II piston enters series production later this year in a new European passenger car, where it contributes to gains in fuel economy and reductions in CO 2. Specific power outputs in engines are likely to increase from current levels of around 95 kW/L to 130 kW/L to coming years. generation pistons.

Especially with increased production volume of renewable fuels and optimized powertrain solutions for flexible fuel vehicles, there is a chance for combustion engines to not only remain in the market but also be sustainable for future vehicle. The intake manifold was modified for high pressure EGR feed and port fuel injection (PFI).

bar decreases the BSFC (brake specific fuel consumption) up to 14% compared to the air-hybrid engine, while resulting in a simultaneous increase in the engine’s power BMEP (brake mean effective pressure) by 140%. You can either feed [two expansion cylinders] or the logical, more simple approach is that you downsize the compression cylinder.
