Cummins progressing with lightweight downsized T2B2 diesel for pickup; 40% improvement in fuel economy over gasoline V8

Green Car Congress

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 Earlier post.). l/100 km), and as such would not meet the GHG requirement of 28 mpg (8.4 Exhaust system configuration.

ICCT working paper highlights benefits of current and emerging light-duty diesel technology; “promising pathway for compliance”

Green Car Congress

The ICCT team—John German and Aaron Isenstadt—concluded that diesels have and will retain two significant advantages over gasoline engines: significantly better fuel economy and cargo hauling and towing ability. Meeting the 2025 standard will require an average improvement in fuel economy of about 4.1% Background.

Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

The analysis used the Ohio State University EcoCAR, a student prototype PHEV, as the basis for the preliminary fuel economy evaluation. Internal combustion engines have been significantly improving in the past decade, after the adoption of technologies such as Gasoline Direct Injection, mild electrification, downsizing and turbocharging.

2014 Sprinter van for US standard with new 2.1L diesel; new driver assistance features

Green Car Congress

This downsizing enables lower fuel consumption, accompanied by low emissions and optimum weight. The 4-cylinder Sprinter features a 7-speed automatic transmission with torque converter—the only 7-speed automatic transmission to feature in a van—is refined for maximum fuel economy. Accessory equipment.

Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

converted all vehicle efficiency measurements into vehicle energy efficiency (VEE, km/MJ) based on fuel energy densities reported in each study. This is because the ethanol component may affect the conversion efficiency of the gasoline component in a blend, that is, make an engine more or less efficient in its use of the gasoline component.

Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

Blending 25-50% of this low-temperature ethanol reformate with ethanol or E85 fuels enables dilute engine operation, resulting in substantial improvements in fuel economy and emissions. High-temperature reformers need to burn a portion of the fuel to maintain their reforming temperatures, thereby generating a fuel-economy penalty.

Controlled Power Technologies Packages Its Switched Reluctance Systems in ‘RegEnBoost’ System for Enhanced Support for Downsizing

Green Car Congress

RegEnBoost integrates the three devices into a powertrain electrical power network (PEPN), which also incorporates a DC to DC converter and an enhanced lead acid battery, optimized for fast energy storage and release. Small engines can also be turbocharged to deliver comparable torque and power to a larger naturally aspirated engine.
