FEV testing finds Transient Plasma ignition system increases fuel efficiency and decreases emissions

Green Car Congress

Data was collected with the stock ignition system with a representative ignition strategy, followed by comparison to a drop-in replacement with the TPS nanosecond pulsed power ignition system (coil and plug). The Toyota 2.5L engine was tested at FEV North America and results indicate improvements over the stock ignition system.

What’s Cleaner, An Electric Truck or Plugin Hybrid Truck? It Depends… (Part 2)

CleanTechnica EVs

In Part 1, I discussed the methodology and assumptions that went into my comparison of the F-150 Lightning, the F-150 Hybrid, and a hypothetical plugin hybrid version of the truck. I discuss my methods in Part 1, but to briefly recap, the production emissions are based on vehicle […] Now, let’s see how they stack up.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

The ICCT has conducted a comprehensive global and temporal life-cycle assessment of GHG emissions from a variety of alternative passenger car powertrains and fuels. The life-cycle GHG emissions of cars registered in 2021 are compared with those of cars expected to be registered in 2030. Source: The ICCT.

JATO: new car CO2 emissions rise for the first time in a decade in Europe; diesel down, gasoline up, SUVs up

Green Car Congress

Average CO 2 emissions generated by new cars in Europe increased during 2017—the first rise in 10 years— according to a new analysis by JATO Dynamics. Covering 23 European markets, the study found that average CO 2 emissions increased by 0.3 g/km in 2017, finishing at 118.1 g/km—a difference of 5.5

UCR CE-CERT resting of hybrid construction equipment finds reduction in fuel consumption, but increase in NOx emissions

Green Car Congress

Summary of comparison of NO x emissions and fuel consumption of hybrid (D7E) and conventional (D6) dozers. PM, THC, and CO emission rates were very low for both the D7E and D6T and thus were not able to be quantified as a hybrid benefit or dis-benefit. Negative values mean hybrid benefit and positive values mean dis-benefit.

Ricardo demonstrates processes for evaluating light-duty diesel emissions under coming Real Driving Emissions (RDE) regs

Green Car Congress

Despite the continuing and significant reductions in the legislated limits of light-duty diesel vehicle NO x emissions under the European Euro 1 through 5 regulations of recent years, many studies have demonstrated that real-world NO x emissions appear not to have been reduced as significantly.

ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

The researchers, from Imperial College London’s Transition to Zero Pollution (TZP) initiative, warn that even though electric vehicles remove the problem of fuel emissions, we will continue to have a problem with particulate matter because of tire wear. million vehicles emit around nine thousand tonnes of tire wear particles annually.
