Airplane manufacturer Aviat Aircraft, Inc. and Minneapolis-based Aviation Foundation of America, Inc. unveiled the first dual-fuel, piston-powered aircraft to operate on both compressed natural gas (CNG) and aviation gasoline. The Aviat Husky CNG is on display outside the Innovations Pavilion throughout AirVenture 2013 in Oshkosh, Wis. (29 July through 4 August).

The proof-of-concept Aviat Husky CNG, which flew more than 1,000 miles from Aviat’s headquarters in Afton, Wy., to be at AirVenture, can be powered by CNG or 100LL aviation gasoline with the flip of a switch. It is a mostly standard Aviat Husky A1-C that has been fitted with a 3600 psi (248 bar) CNG fuel tank in addition to its standard aviation gasoline tanks. The only modification made to the engine, a Lycoming IO-360-A1 D6, was the installation of new pistons to increase the compression ratio from 8.50:1 to 10:1.

Chevy Cruze diesel’s variable-swirl mechanism

The basic concept of GM’s variable swirl mechanism. Click to enlarge.

The 2014 Chevrolet Cruze Clean Turbo Diesel’s (earlier post) 2.0L engine uses a variable-swirl intake mechanism to enhance performance while reducing emissions. The variable-swirl intake manifold design optimizes air charge mixture motion in the cylinders for a more efficient combustion.

In Cruze’s variable-swirl intake manifold, each cylinder has two separate intake ports, with one of them controlled by a valve. During variable swirl, each throttle valve varies how much it opens to create mixture-motion of air and fuel within each cylinder. The effectiveness of any such variable mechanism is linked to the quality of its controls; GM’s engineering team spent a great deal of effort calibrating the actuator precisely to open and close the valves for optimal performance.

Ford will offer the 2014 F-150 with the ability to run on compressed natural gas, making Ford the only manufacturer in the US with an available CNG/LPG-capable half-ton pickup. GM offers a CNG bi-fuel option for its HD pickups (e.g., Silverado 2500HD and 3500 HD and Sierra HD). (Earlier post.)

The 2014 Ford F-150 with 3.7-liter V6 engine will be available this fall with a factory-installed, gaseous-fuel prep package that includes hardened valves, valve seats, pistons and rings so it can operate on either natural gas or gasoline through separate fuel systems.

Keyera and Kinder Morgan to construct crude oil rail loading terminal in Edmonton

Keyera Corp., a Canadian mid-stream company, and Kinder Morgan Energy Partners formed a 50-50 joint venture to build a crude oil rail loading facility in Edmonton, Alberta, called the Alberta Crude Terminal. When complete, the Alberta Crude Terminal will be able to accept crude oil streams handled at Kinder Morgan’s Edmonton Terminal for loading and delivery via rail to refineries anywhere in North America.

PSA evaluating PowerGenix NiZn batteries for start-stop systems

PowerGenix, the developer of high-performance, automotive Nickel-Zinc (NiZn) batteries, has entered into an innovation contract with PSA Peugeot Citroën Automobiles under which PSA will conduct a comprehensive evaluation of the use of PowerGenix’s NiZn batteries as a replacement for lead-acid in stop-start vehicles.

Start-stop systems shut off engines while the vehicle is at rest and restart it instantly and automatically upon re-engaging the gas pedal and are one of the most cost-effective and efficient means of optimizing fuel economy. Current estimates put stop-start efficiency improvements at around 5-8%, while next generation systems may achieve savings as high as 12-15%.
