At the North American Commercial Vehicle Show (NACV) in Atlanta this week, Bosch is showcasing its portfolio of automated, connected and electrified technologies for commercial vehicles. The Bosch Central Gateway (CGW) enables secure connectivity in commercial vehicles. Powertrain concepts. Thermal management.
A Fixed Pitch Continuously Variable Transmission (FPCVT) assembly with two FPCVT units connected in series. Multiple chains provide multiple contact points to keep the power and load sides connected during a complete rotation. Tags: ConceptEngines Transmissions. Source: Ken Hawthorn. Click to enlarge.

The bearings are mounted on the underside of the two inter-connected pistons, which maintain the desired bearing-to-trilobe clearance throughout the stroke. The counter rotation is performed by a reverse gear set at a 1:3 ratio shaft providing two strokes of a piston to 360 degrees of output shaft rotation—the same as a conventional engine.
The Scuderi Engine is a split-cycle design that divides the four strokes of a conventional combustion cycle over two paired cylinders. The engine has two crossover passages that connect the two cylinders, which separate the four strokes of the pistons. a more efficient internal combustion engine.
The injection of the additional air during transients can overcome the poor driveability usually associated with heavily downsized and supercharged engines, the team notes. In the pneumatic hybridization scheme, each cylinder is connected via a fully variable charge valve to a shared pressure tank. Dönitz et al. Source: ETH Zürich.
Induction air enters at the center of the engine and compression/expansion occurs at the periphery producing uniform heat flow characteristics as air circulates around the two sides of the engine. The two rotors are connected together by a connection rod that has a quasi-circular orbit. Overview of the Libralato Engine.
This new unit will condition the raw power and produce useable power for commercial connectivity and use. In addition to the exciting engineering progress made on the OX2 engine/generator, the company has initiated efforts to raise additional capital to fund the OX2’s 30 Kw Generator final development stage. OX2 animation files.
The engine-pack contains a combustion engine which produces 82 hp and is connected to a continuously variable transmission (CVT). Full hybrid system output (front motor and rear engine) is 150 hp. Fuel consumption is less than 6 l/100 km (39 mpg US) and the range surpasses 600 km (373 miles).
For the study, Honda installed a small pump separate from that of engine lubricating oil pump. Oil passage was constructed from the external pump through the crankshaft and connecting rod to the piston. Kawajiri (2009) Advanced Control System of Variable Compression Ratio (VCR) Engine with Dual Piston Mechanism (SAE 2009-01-1063).
The Garric engine divides the four elements of intake, compression, combustion and exhaust among multiple double-faced pistons moving in a constant direction. The central hub (or power shaft) is connected to a disc with one or more pistons attached. A detailed animation of the cycle is available on the Garric Engine website.
Linear free piston engines can capture a much greater proportion of the energy contained in the fuel burnt, not only because the linear gas expander extracts electrical power directly from the expansion stroke, but also by optimizing the motion of the piston to improve combustion efficiency.
