Those help to increase performance for several characteristics, such as safety, comfort, fuel economy and many more. Designing such products using a classic approach, is usually ineffective. A modern development process should be able to predict the behavior of the complete system for all functional requirements and including physical aspects ...
These may improve fuel economy because the engine runs slightly lean as a consequence. However, running leaner than the manufacturer intended can cause overheating, piston damage, loss of maximum power and poor emissions (e.g., higher NOx due to higher combustion temperatures, or, if misfiring occurs, greater hydrocarbon emissions).
The two-mode hybrid drive system manufactured by Allison Transmission was first used in New Flyer transit buses which entered revenue service in 2004; [31] in testing at the National Renewable Energy Laboratory, measured fuel economy improved from 1.46–3.03 mpg ‑US (161–78 l/100 km) for conventional diesel bus to 2.56–3.98 mpg ‑US (91 ...
The ecoDemonstrator Program is a Boeing flight test research program, which has used a series of specially modified aircraft to develop and test aviation technologies designed to improve fuel economy and reduce the noise and ecological footprint of airliners.
Arvin Meritor, a Tier 1 supplier of automotive technology, at one time, was experimenting with a plasma reformer technology which would use hydrogen produced from the fuel to enhance engine combustion efficiency and reduce emissions of NO x. [26] This reference states that a 20% to 30% increase in engine thermal efficiency is possible. However ...
It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy. Estimated performance on EPA tests shows a 5.5–7.5% improvement in fuel economy. [1] GM's Active Fuel Management [2] technology used a solenoid to deactivate the lifters on selected cylinders of a pushrod V-layout engine.
Investors are always looking for growth in small-cap stocks like Metro Performance Glass Limited (NZSE:MPG), with a market cap of NZ$98m. However, an important fact which most ignore is: how Read ...
Since then, development has been iterative and today designs exist from several stages of electronic automatic transmission control development. Transmission solenoids are a key component to these control units. The evolution of modern automatic transmission and the integration of electronic controls have allowed great progress in recent years.
