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.

Scuderi Group, Inc., the developer of the Scuderi Split-Cycle Engine for mobile applications (earlier post) has signed a Memorandum of Understanding with the Asociación de Miembros de la Policia de Puerto Rico for the first Scuderi Split-Cycle Engine to be utilized as a stationary liquefied petroleum gas (LPG) generator with compressed air energy storage (CAES) capability.

The signing of the agreement begins the process of building and installing the first LPG-powered Scuderi power generator and energy storage systems. According to the agreement, Scuderi Group will build and install the power generation units at the Association’s San Juan headquarters and adjoining elderly care facility and at other locations around the island include buildings in Trujillo Alto, Ponce, and Maunabo.

Responding to growing customer demand in Europe for small cars with low running costs and low emissions, Kia is introducing a bi-fuel gasoline-LPG model to its Picanto small car range. The new variant, introduced at the Frankfurt show, will record fuel economy in LPG mode of 5.8 l/100 km (40.6 mpgUS) and CO2 emissions of 100 g/km; automatic stop-start (ISG) equipped models will achieve 5.6 l/100 km (42 mpgUS) and 97 g/km.

Picanto LPG is powered by a special version of Kia’s three-cylinder 1.0-liter Kappa engine which produces 67 ps (66 hp, 49 kW) and 90 N·m (66 lb-ft) of torque. To process LPG the engine is fitted with an additional fuel system featuring a solenoid valve, vaporiser (which turns the liquid LPG into a gas by reducing its pressure by 0.7 Bar), a gas filter and an injector module.
