Toyota introduces new LPG hybrid taxi in Japan; trial of lane-specific congestion info from taxi data

October 23, 2017

Toyota Motor Corporation has introduced a new taxi vehicle for Japan, the “JPN Taxi.” Equipped with a newly developed liquefied petroleum gas (LPG) hybrid system, the new model offers 19.4 km/L (45.6 mpg US, 5.51 l/100 km) fuel economy and sharply reduced CO2 emissions. Toyota made enhancements to safety equipment, including adding the Toyota Safety Sense C package and six SRS airbags as standard features. The new model is now available at Toyota and Toyopet dealers nationwide.

The new model showcases a people-friendly, universal design that provides usability and comfort to a wide range of people through continual innovations and improvements, from grab handles to the overall vehicle structure. Design features include a low, flat floor, making it easy for customers to ingress and egress from the taxi, a wide-opening, power rear sliding door (left side only) and space to accommodate wheelchair users.

Canadian team proposes new propane phase-change thermal management system for hybrid electric battery packs

Canadian team proposes new propane phase-change thermal management system for hybrid electric battery packs

Researchers at the Clean Energy Research Laboratory, University of Ontario Institute of Technology are proposing a new propane phase-change thermal management system for hybrid electric vehicles that use propane as the fuel for the engine. (Further studies are possible to modify the systems for use on other kinds of electric vehicles.)

The proposed system boils liquid propane to remove the heat generated by the batteries, and the propane vapor is used to cool the part of the battery that is not covered with liquid propane. The results of their study, published in the Journal of Power Sources, show that the propane-based thermal management system provides good cooling control of the temperature of the batteries under high and continuous charge and discharge cycles at 7.5C.

New MAN Diesel & Turbo ME-GIE two-stroke engine can use VOCs as fuel

March 11, 2017

The world’s first ME-GIE ethane-combusting two-stroke engine has been delivered from MAN Diesel & Turbo licensee Mitsui Engineering & Shipbuilding Co., Ltd. (MES) in Japan. The Mitsui-MAN B&W 7G50ME-C9.5-GIE is the first engine in a series of three.

Further research has led to new possibilities for this engine leading to new prospects for multi-fuel combustion including the combustion of waste gas. The benefits of the diesel-type combustion are now fully exploited in the ability of the two-stroke engine to run on almost any gas quality without efficiency reductions, and in the complete combustion maintained by a relatively high gas injection pressure.

DOE awards $18M to 5 projects to accelerate development of plug-in electric vehicles & use of other alternative fuels

December 23, 2016

The US Department of Energy (DOE) is awarding $18 million to five projects for research, development, and demonstration of innovative plug-in electric vehicle (PEV) and direct injection propane engine technologies, as well as community-based projects to accelerate the adoption of light, medium and heavy duty vehicles that operate on fuels such as biodiesel, electricity, E85, hydrogen, natural gas, and propane.

Odyne Systems, LLC will receive $2.9 million to develop and demonstrate plug-in hybrid work trucks (class 7) that reduce fuel consumption by more than 50% and eliminate fuel consumption during stationary operations.

San Diego MTS deploys 77 propane buses; Ford F-550 and E-450 chassis with ROUSH fuel systems

December 08, 2016

The San Diego Metropolitan Transit System (MTS) rolled out its new fleet of 77 buses fueled by propane autogas. The alternatively fueled buses will help the agency reduce its operating costs, and will reduce emissions by 2 million pounds per year.

MTS purchased 31 minibuses and 46 paratransit buses fueled by propane. The minibuses are built on the Ford F-550 chassis and the paratransit buses are built on the Ford E-450 chassis. Each model features a Ford 6.8L V10 engine with a ROUSH CleanTech propane autogas fuel system. The ROUSH CleanTech liquid propane autogas fuel system consists of four major subsystems which include the fuel rail assembly; fuel line assembly; fuel tank assembly; and the powertrain control system.
