Hydraulic Drivetrain Design

CurtisEllzey — Thu, 09 Jul 2009 14:00:00 GMT
Jude Hueber, Lightning Hybrids Senior Engineer - Powertrain, Controls and Chassis - describes why they chose a parallel hydraulic system in their design. Depending on how the electrical controls are arranged, a parallel system can serve to lessen the load on a conventional internal combustion engine at all times. This flexibility allows tuning to increase performance and drivability of the vehicle and eliminate many failure modes that would render the vehicle unable to drive.

Lightning Hybrids Hydraulic Drivetrain - Part 1

CurtisEllzey — Tue, 07 Jul 2009 14:00:00 GMT
Dan Johnson, Lightning Hybrids CEO and Co-Founder, walks us through the hydraulic drivetrain used in their LH4 and LH3 models. Their parallel hydraulic hybrid system is similar to many of the electric hybrid vehicles on the market today wherein a conventional internal combustion engine can drive the vehicle by itself, or be assisted by another power system which can be mechanically coupled or decoupled from the main conventional driveline.

Milner Continuously Variable Transmission

CurtisEllzey — Wed, 20 May 2009 14:00:00 GMT
The Milner Continuously Variable Transmission has a compact, in-line form factor and flexible configuration which makes it ideal for applications where space is at a premium and/or unnecessary weight results in additional cost (battery power, fuel efficiency, etc.). At the heart of the Milner CVT lies a rolling traction variator that is capable of efficiently handling both high torque and high speeds. It is essentially a variable geometry, four-point contact ball bearing with power transfer to or from the planet balls by roller followers located between the balls and mounted on a rotating carrier. The MCVT allows for unprecedented power density (as a function of both size and mass) among traction CVT’s, and provides significant benefits over existing belt driven CVT’s.

Designing the Lincoln C Concept

CurtisEllzey — Wed, 06 May 2009 13:00:00 GMT
Machine Design's Lee Teschler talks to Chief Designer Gary Braddock from Ford about designing the Lincoln C concept car. The Lincoln C concept brings Lincoln luxury and HMI (Human Machine Interface) to a smaller, C-sized footprint. Because the Lincoln C concept is two inches wider than conventional C-class vehicles, it offers the roominess of a 1961 Continental at almost half the length (and with style to spare). A life-like avatar is used to connect the driver to the vehicle and all the functionality offered through key systems such as Ford's signature HMI and SYNC. The Lincoln C concept also showcases Ford Motor Company's newest combination of fuel-efficient powertrain innovations: a four-cylinder EcoBoost engine mated to a dual-clutch PowerShift transmission.

Audi 3.0 TDI Clean Diesel

CurtisEllzey — Wed, 08 Apr 2009 14:00:00 GMT
Audi's Günter Schiele elaborates on the 3.0 TDI's downstream exhaust emission control system, which reduces emissions by up to 90 percent. The system uses AdBlue, a biologically degradable, waterborne additive that is injected in small amounts upstream of the DeNOx catalytic converter. In addition to the catalytic converter, the exhaust emission control system comprises the metering module, the AdBlue tank and heated lines, as well as an extensive system of sensors. The additional oxidizing catalytic converter and the highly efficient, regulated diesel particulate filter round off the comprehensive emission control system. Also watch this episode: Cleanest Diesel in the World.For more information, go to: Audi.

Cleanest Diesel in the World

CurtisEllzey — Tue, 07 Apr 2009 14:00:00 GMT
Audi's Manager of Diesel Engineering, Günter Schiele, discusses what it takes to produce the "cleanest diesel in the world", Audi's six-cylinder 3.0 TDI used in their Q7 SUV and the Sportback concept car revealed at the 2009 NAIAS. The diesel engine development engineers at Audi have combined an entire package of innovative measures for this latest TDI generation: the piezo common rail system with an injection pressure of 2,000 bar, highly efficient exhaust gas recirculation and optimized turbocharging result in significantly reduced raw engine emissions.

Myers Motors NmG Electric Vehicle

CurtisEllzey — Thu, 05 Mar 2009 15:00:00 GMT
Engineering TV visited Myers Motors and Brad Hirsch at the NAIAS in Detroit to take a look at their affordable lithium-powered personal electric vehicle. The vision of Myers Motors is for every garage to have a sub-$20,000 highway speed electric vehicle. Their current line-up features the Myers Motors NmG (No more Gas) single-passenger electric vehicle (a two-seater is in the works). They claim the NmG's rechargeable 156 volt DC motor enables about 1000 miles of driving for only $20 of electricity (at $0.10 / kWh). Perfect for commutes and small enough to park just about anywhere, it can even reach a 75 mph top speed and is highway legal. For more information, go to: Myers Motors.
