Because emergency services require high levels of availability and have an unpredictable demand, retail electric motorcycles are unlikely to present a cost-effective solution. Existing electric motorcycles have been designed with the retail market in mind, and can be both expensive and slow to charge.
Christopher Thomas, BorgWarner VP, Advanced Engineering, Engine Group and VP, Advanced Engineering, Drivetrain Group presented the basic concepts of VEMB and current BorgWarner test results at the recent SAE 2012 High Efficiency IC Engine Symposium. —Christopher Thomas. Virtual Cylinder Deactivation (VCD).
MAHLE Powertrain is presenting a new, prototype 48-volt battery with optimized battery cooling and cell chemistry to enable increased charge and discharge rates. Thus a compact and cost-effective battery that is capable of high charge and discharge power levels relative to its storage capacity (high C rates) is desirable.
The Automobile Division of the Institution of Mechanical Engineers has awarded its Prize for the Environment to Ricardo, Ford Motor Company, Controlled Power Technologies and Valeo engineers for their paper HyBoost—An Intelligently Electrified Optimized Downsized Gasoline Engine Concept. Earlier post.). Earlier post.)
It is the first time that Hyundai has presented a dual-clutch transmission with seven gears, combining the benefits of both automatic and manual transmissions. Another premiere at the Paris Motor Show 2014 is the seven-speed dual-clutch transmission (7DCT), also showcased in the i30 CNG concept car.
This common core also provides greater confidence in the robustness of prototypes, while minimizing the cost of variants further supports the development of 48V systems. SR machines are ideally suited to this concept of lowcost development, while reducing the cost of production components.
During his presentation at the recent California Air Resources Board (ARB) ZEV Technology Symposium, Tatsuaki Yokoyama, from Toyota Motor Engineering & Manufacturing North America, said that Toyota aimed to reduce the cost of fuel cell vehicles to 1/10 of the current level by design and materials improvement by commercialization in 2015.
Furthermore, they found that the limited working time at the high temperature presents an opportunity to use graphite of low surface areas, thereby prospectively prolonging the EV lifespan to greater than two million miles. The very fast charge allows us to downsize the battery without incurring range anxiety.
At the 2016 International VDI Congress “Drivetrain for Vehicles” in Friedrichshafen, Germany, John Fuller, Director of Concepts & IP for Torotrak Group, presented and discussed the company’s latest advances to optimize its full-toroidal variator technology for the light vehicle market as applied in continuously variable transmissions (CVTs).
The company presented these latest test results in a paper at the SAE 2012 World Congress in Detroit. With the extended lean operation of the sleeve-valve engine, NO x emissions remain low for light to medium loads and rise back to typical levels during the brief enrichment periods required to maintain competitive BMEP levels at higher loads.
Current mild-hybrid vehicle projects, in partnership with Ford and Hyundai/Kia, that utilize advanced 48V lead-carbon batteries, can reduce CO 2 emissions by 15-20%, according to the latest data from the Advanced Lead Acid Battery Consortium (ALABC), presented at the Advanced Automotive Battery Conference (25-28 January, Mainz).
Delphi presented the work in a technical paper “Development of High-Pressure Common Rail Systems Incorporating Advanced Electronic Control Strategies for Future Heavy-Duty Vehicles,” at the 33 rd Vienna Motor Symposium last week. This concept system is expected to be ideal for heavily downsized applications and developing markets.
A range of aftertreatment technology options are available to automakers seeking to achieve compliance with the impending EU Real Driving Emissions (RDE) regulations, according to the results of a Ricardo research project presented recently at the SIA Powertrain international conference and exhibition in Rouen, France. liter diesel engine.
Among their general findings are: Increasing battery power in plug-in hybrids (10-, 20- and 40-mile AER, from low to high power) had little effect on fuel consumption results because the battery power can provide most of the driving on the test cycles, so the fuel economy only differs slightly. Brooker, A.; Thornton, M.; NREL Report No.
Both Multec types of injectors feature best-in-class NVH (Noise, Vibration, Harshness), which is important because it saves the vehicle manufacturer the cost and weight of additional noise reduction materials. However, these engines can present significant challenges for the ignition system.
These trucks haul 80% of goods in the United States and use about 28 billion gallons of fuel per year, accounting for around 22% of total transportation energy usage—presenting a significant opportunity for carbon emissions reduction and energy savings for a key segment of the US transportation sector. Description. Federal funding.
High-research octane number (RON) fuels are known to enable more efficient, higher-performance SI operation via engine downsizing and boosting. Fuel research will focus on low-GHG advanced biofuel/petroleum blends.
Steven Kaye: ONE’s anode-free cell advantages include high energy density (thin lithium metal anode), lowcost (no anode present during cell assembly, low-cost liquid electrolyte), and abundant raw materials (mostly manganese, zero cobalt). The challenge is that anode-free cells still have low cycle life.
At present, PHEV technology alone is equipped to improve the current electric grid. The car can refuel during periods of low demand on the grid, and if equipped with a bi-directional charger, can actually replenish the grid with excess energy gleaned from a renewable resource. Engineering Advantages of the PHEV.
The new engine will achieve high efficiency using the Atkinson Cycle with an 18:1 compression ratio, combined with aggressive engine downsizing. Engine downsizing is a key tool in improving fuel economy. When loads on the engine are low the compression ratio can be raised to as much as 18:1, Envera said.
This is from "Commercializing Plug-In Hybrids" (pdf), the current CalCars 24-slide presentation about PHEVs available along with other documents at CalCars Downloads. Agrees on environmental and economic benefits, though some presentations backtrack on that; says batteries need further development before commitment to mass-production.
