liter Isuzu diesel engine, demonstrates a 35% fuel efficiency improvement over traditional vehicles in the FedEx Express fleet. The Reach van, with its four-cylinder, 3.0-liter
They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology. Information pertaining to these emissions in diesel engine exhaust is much less complete than that for the regulated pollutants. —Chin et al.
Susumu Hosoi, President of Isuzu Motors Ltd., At the meeting, the chief executives of the assembled companies agreed to continue their joint efforts to work with government bodies to promote harmonized global standards. extended an invitation to the chief executives to hold their 2014 meeting in Tokyo.
It is generally agreed that very high injection pressures are needed to improve engine thermal efficiency fuel economy, lower heat rejection, and to minimize exhaust aftertreatment complexity and costs. Millions of this type of injector have been used since the mid 1990s by Navistar, Ford, Caterpillar, and Isuzu.).
Isuzu D201 35 hp diesel engine (left) and the LiquidPiston 40 hp X2 Prototype (right). Other features of the X2 include: Quiet operation: engine lacks poppet valves and over-expansion minimizes exhaust noise. Click to enlarge. LiquidPiston, Inc. Power modulation by cycle skipping increases efficiency and recaptures heat.
liter, naturally-aspirated, in-line four-cylinder direct-injection Isuzu diesel engine. However, there is an increase in NO 2 in the exhaust gas. Combustion characteristics are also analyzed to relate to the changes in particulate and NO x. —Tsang et al. The team conducted experiments on a 4.3-liter,
will address natural gas engine emissions and efficiency improvements by developing a natural gas specific combustion design utilizing optimized in-cylinder charge motion and cooled exhaust gas recirculation (EGR). Cummins Inc. g/bhp-hr NO x capability with reduced aftertreatment cost; and demonstrating a diesel-like torque curve.
Furthermore, and in relation to exhaust emission requirements, the manufacturers agreed to recommend the introduction of legislative requirements regarding market fuels, in order to ensure that the appropriate, high-quality fossil and renewable fuels are globally available for today’s vehicle technologies.
With intake or exhaust (or both) valve deactivation in place, inactive cylinders are prevented from pumping air through the engine, which enables effective use of three-way catalyst technology. With combustion occurring preferentially in this regime, the engine combustion system can potentially be optimized to match this operating area.
These include the Toyota LandCruiser, Ford Everest, Isuzu MUX, Nissan Patrol and Mitsubishi Pajero Sport – all mid- or full-size SUVs. The post Australia introduces its first exhaust rule but makes all the mistakes the US did appeared first on Bauaelectric Auto News.
Its basic operating mechanism is to apply combinations of very early or late injection timing, high injection pressure, low compression ratio, and high exhaust gas recirculation (EGR) levels to achieve a separation between the end of injection and the start of combustion, so that a premixed charge can be achieved before ignition occurs.
Without being exhaustive, let’s take a look at some examples. Geo renamed the Nova as the Geo Prizm and added other models jointly produced with Isuzu and Suzuki in North America and Japan, but separated them from its “American” cars. I’m looking primarily at the U.S. market; many other options await in Europe and Asia.
