Renault has previewed a new electric vehicle motor, designed by its engineers and manufactured at its Cléon plant in France, as well as a new dual-fuel gasoline/LPG combustion engine. Both are slated to enter production in 2015. Rémi Bastien, Renault’s Director of Innovation Engineering, noted that “The future of mobility calls for the same command of electric motor technology as it does of internal combustion engines. We are consequently active on every front, from internal combustion engines to electric motors and alternative energies.

New Renault electric motor. The synchronous electric motor with wound rotor develops 65 kW and peak torque of 220 N·m (162 lb-ft), and features an integrated Chameleon charger (earlier post). Integration, miniaturization and simplification were the three objectives that guided the design of this motor.

Westport Innovations acquires alt fuel systems company Prins Autogassystemen for €12.2M

December 03, 2014

Natural gas engine and vehicle company Westport Innovations Inc. has acquired Netherlands based Prins Autogassystemen Holding B.V. for €12.2 million (US$15.1 million) through a combination of €6.6 million (US$8.2 million) in assumed liabilities and €5.6 million (US$6.9 million) in cash.

Founded in 1986, Prins is a leading developer of high quality alternative fuel systems powered by liquefied petroleum gas (LPG or propane), compressed natural gas (CNG), and liquefied natural gas (LNG) for light-, medium-, and heavy-duty applications. Prins operations in Europe will be combined under the Westport Applied Technologies business unit.

Professors Pål G. Bergan and Daejun Chang and of Ocean Systems Engineering at Korea Advanced Institute of Science and Technology (KAIST) have developed a box-type, large-size pressure vessel for the storage and transportation of liquids such as liquefied petroleum gas (LPG), compressed natural gas (CNG), or liquefied natural gas (LNG). The project was sponsored by POSCO, a multinational steel-making company based in Pohang, Republic of Korea.

Pressure vessels have many applications and are widely used within the petrochemical, energy, and other industrial sectors where the transport and storage of many types of pressurized gases and fluids are essential. Pressure vessels must be designed, manufactured, installed, and operated strictly in accordance with the appropriate codes and standards since they can, in cases of leak or rupture, pose considerable health and safety hazards.

Fiat updates 500L range for 2014 with new 120 hp diesel and gasoline engines, LPG version

February 11, 2014

Fiat is updating its 500L range for 2014 with two new turbocharged 120 hp (88 kW) engine options—the 1.6 MultiJet II turbodiesel and the 1.4 T-Jet gasoline—and a dual fuel LPG/gasoline variant of the 1.4 T-Jet.

120 HP 1.6 MultiJet II. The adoption of a small variable geometry turbocharger developed by Honeywell enables high torque delivery at low rpm— 320 N·m (236 lb-ft) at 1,750 rpm—and maximum running flexibility. A third-generation Common Rail injection system uses new injectors to manage up to eight injections per cycle. This enables actuating increasingly advanced strategies focused on optimizing the combustion— such as the Injection Rate Shaping (IRS) system which involves two consecutive injections so close together in time as to generate a continuous and modulated fuel supply into the cylinders.
