Ricardo’s “deep” Miller cycle concept: Magma

Green Car Congress

A long exhaust stroke then extracts maximum efficiency. The in-cylinder gases are thus expanded and cooled as the piston descends, before being re-compressed as the piston rises again. Early closure of the inlet valves leaves a smaller window for the charge fill the cylinder. Magma boost system layout. 2016) Click to enlarge.

Bain: Germany’s goal of 1M electric cars by 2020 is unattainable; fewer than 50,000 units on road by end of this year

Green Car Congress

By the end of 2015, there will be a total of about 50,000 electric cars and plug-in hybrids on the roads in Germany (about 75% below plan); nevertheless, structural transformation towards electromobility is continuing, according to the firm. Build the charging infrastructure.

Mazdas new SKYACTIV gasoline and diesel engines are steps on the road to its Ideal Engine; focus on compression ratio

Green Car Congress

Since this energy loss is primarily thermal in nature and can be attributed to the exhaust, cooling system, and engine and transmission surfaces, Mazda’s R&D team’s central focus is on improving the engine’s thermal efficiency cost-effectively. This corresponds to a 23% reduction in fuel consumption and, therefore, CO 2 output.).

Common Rail injection reduces the generation of particles, while exhaust-gas recirculation (EGR) reduces NO x. This improves the exhaust gas values across a wide speed range. The low-temperature cooling system with its own dedicated circuit makes charge-air cooling more effective in the Euro 6 version.

MIT/Tsinghua high-rate aluminum yolk-shell nanoparticle anode for Li-ion battery with long cycle life and high capacity

Green Car Congress

In an open access paper in the journal Nature Communications , they reported that the Al yolk-shell anode achieved a 10 C charge/discharge rate with reversible capacity exceeding 650 mAh g −1 after 500 cycles, with a 3 mg cm −2 loading. The charge/discharge rate was set at 1 C. The charge/discharge rate was set at 1 C. (b)

Update on DOE Co-Optima project to co-optimize fuels & engines; goal of 30% per vehicle reduction in petroleum

Green Car Congress

In October 2015, the US Department of Energy’s (DOE) launched a broad, joint effort to co-optimize the development of efficient engines and low greenhouse-gas fuels for on-road vehicles with the goal of reducing petroleum consumption by 30% by 2030 beyond what is already targeted. We’re not going to say “Ethanol.

World Bank/ICCT report provides guidance to reducing black carbon emissions from diesels in developing countries

Green Car Congress

In 2012 the International Agency for Research on Cancer re-categorized diesel engine exhaust as carcinogenic to humans based on evidence that sufficient exposure is associated with an increased risk of lung cancer. Earlier post.). Cost benefit.
