« Kenworth developing hydrogen fuel cell, Near Zero NOx CNG series hybrid Class 8 prototypes for SoCal ports; CNG hybrids | Main US Hybrid has unveiled a zero-emission Class 8 fuel cell port drayage truck featuring its PEM fuel cell system during the Advanced Clean Transportation (ACT) Expo at the Long Beach Convention Center. The truck, which will be operated by Total Transportation Solutions, Inc (TTSI), is one of two fuel cell demonstration tractors scheduled for delivery at the Ports of Los Angeles and Long Beach. (Earlier post.) The fuel cell tractor, a Navistar International ProStar day cab, features US Hybrid’s FCe80, 80 kW PEM fuel cell system and a 500 hp traction motor with 2,900 lb-ft of direct drive torque (3,750 N·m). It has a gross vehicle weight rating of 80,000 pounds, an estimated driving range of 200 miles under normal drayage operation, and can be fully refueled in less than nine minutes. US Hybrid plans to expand its Connecticut production facility via a partnership with China-based Jiangsu Dewei Advanced Materials. The US FuelCell, Inc. (USFC) facility will focus on the production of US Hybrid’s PEM fuel cell systems, including the FCe80, an 80kW fuel cell engine for heavy-duty trucks and transit buses, and the FCe40, an 40kW fuel cell engine for class 6 and 7 trucks and medium-duty transit buses. The compact and high efficiency FCe80 and FCe40 units have been designed to be integrated, controlled, and serviced just like a conventional engine with J1939 diagnostics and easy access to critical components to minimize service time. The FC engines are utilizing US Hybrid’s advanced freeze capable technology, which enables start at temperatures as low as -30 degrees Celsius without a cold climate option package. USFC anticipates production and delivery of more than 1,200 PEM fuel cell engines in the next 36 months. The expansion of production facilities in US and China will enable the company to build and deliver 2,000 fuel cell engines per year in the US and additional 2,000 engines in China. The higher-volume fuel cell engine production capability will enable fleets to realize a comparable return on investment as other clean fuel engines. US Hybrid Corporation has provided electric and hybrid-traction drive systems for medium- and heavy-duty commercial trucks, municipality vehicles, and fuel cell transit buses throughout the world, with more than one million accumulated kilometers of operation. Notable recent integration projects include hybrid street sweepers for the New York Department of Sanitation, hybrid port trucks for the New York Container terminals, fuel cell buses for Sunline Transit, fuel cell powered class-8 drayage trucks for operation at the Port of Los Angeles and Port of Houston, and a range of full cell vehicles (shuttle buses, step vans, military vehicles, port trucks) for Hickam Air Force Base in Hawaii. US Hybrid is also providing Caltrans with a fuel cell street sweeper. Dewei, established in 1995, is the largest high molecular material producer and distributor in China. The rapidly growing company, which is a supplier for General Motors, Volkswagen and Toyota, and a key shareholder of Guizhou Aerospace Special Vehicle Co., has recently experienced nearly 30% year-over-year revenue increases.

A detachable blast structure for use as an underbelly device of a personnel cabin for a vehicle, is disclosed. The blast structure comprises at least one modular section attachable to the underbody, and means for attaching and detaching the modular sections to the underbody. The modular sections are separately attachable and detachable from portions of the vehicle as needed, depending on the situations and environment the vehicle will be exposed to and the level of protection required.

A blast absorption structure and system for use in absorbing blast forces exerted upon an armored vehicle is disclosed. The blast absorption structure includes a first absorption component and a second absorption component, wherein the first and second absorption components deform to absorb and slow the forces prior to reaching an occupant of the cabin. Deformation of the first and second components reduces the blast force load transmitted through the vehicle structure to the occupants lower extremities, thereby avoiding catastrophic injury to the lower extremities.

A system and method for improving the engine braking capacity for a vehicle is disclosed. The system and method include providing a compression release braking system, providing an energy drawing component for increasing power draw on the vehicle engine, and, increasing the engine braking capability by synchronizing operation of the energy drawing component with operation of the compression release braking system. The energy drawing component includes a hydraulic fan, which is part of the cooling system of the vehicle. Increasing the speed of the fan draws energy from the engine, which in turn, increases the braking capability of the engine.

A load transfer system and device for use in connection with structures forming a personnel cabin for a vehicle, is disclosed. The load transfer system includes a first surface, a second surface joined in an overlapping configuration with the first surface at a plurality of connection points, and, a load transfer device, wherein a force impacted on the first surface transfers via the load transfer device away from the connection points to prevent shearing of the connection points from the surfaces. The system and device are particularly useful on military vehicles, which are frequently subjected to high impact activities, including shock waves from a mine blast or impact between two objects, such as a vehicle crash. These events can subject the structures forming the vehicles and cabins to large shear stresses, particularly on the connection points holding the structures together, which could cause the connections to fail.
