Start-up Eco-Motive developing dual-fuel “H” engine; parallel, independently fueled piston banks

Green Car Congress

Each piston bank operates independently of the other but is housed within the same engine block and has separate lubrication systems. The Eco-Motive H-motor—basically two separate engines housed within the same engine block—can be powered by either gasoline or compressed natural gas (CNG), at the driver’s decision.

Experts view on future transportation fuels

Green Car Congress

Since internal combustion engines will remain the primary mode of choice for mobility in the foreseeable future, both alternative (renewable) fuels and high-performance combustion concepts/ engines using fuels adapted for that purpose will be preferred for reducing the combustion impact on climate change.

ECONAMIQ: Flexible over-expansion with cylinder deactivation can reduce ICE fuel consumption by up to 20%

Green Car Congress

The company presented its first results at the annual ASME ICEF (Internal Combustion Engine Fall) conference in Chicago. An adaption of cylinder de-activation technique called ECONAMIQ over-expansion can be applied to engines to improve fuel efficiency. In addition, engine vibrations are reduced during cylinder deactivation.

Dalian team proposes jet controlled compression ignition to control PCCI phasing in a hybrid pneumatic engine

Green Car Congress

Researchers at the Dalian University of Technology have proposed a novel method to control premixed charge compression ignition (PCCI) phasing in internal combustion engines in all load operations. It compresses the pressurized gas produced by exhaust gas turbocharger, comprising fresh air and exhaust gas introduced from the EGR valve.

Liquid Air Energy Network forms in UK; focus on transportation and energy storage

Green Car Congress

A cryogenic engine such as the Dearman piston engine produces zero emissions at the point of use; has low greenhouse gas emissions provided the liquid air or nitrogen is produced from low carbon electricity; has energy and power density on a level with battery electric technology; and has the potential for rapid refueling.
