Researchers at Environment Canada have found that vehicle exhaust is a significant source of isocyanic acid (HNCO), a toxic gaseous acid that is a product of various forms of combustion and a potential health concern. mg kg fuel –1 and were significantly higher than previous biomass burning emission estimates.
An electrically driven compressor for precise exhaust gas recirculation is also used. Then we modify the timing and pressure of the injection, among other things, and look at exhaustemission values and fuel consumption. This is done via exhaust gas recirculation (EGR). —Patrik Soltic.
In the spring 2014, the GasOMeP project (Gasoline Vehicle Emission Control for Organic, Metallic and Particulate Non-Legislative Pollutants) got underway. The carcinogenic potential in one cubic meter of exhaust gas from gasoline direct injectors is up to 1,700 times higher than the EU limit for clean air. Click to enlarge.
A review of 43 studies of the effects of E15 (15% ethanol blends) on Model Year 2001 and newer cars by the National Renewable Energy Laboratory (NREL) found that the studies reviewed showed no meaningful differences between E15 and E10 in any performance category. Regulated emissions. Fuel system and engine durability.
Emissions under the dual-fuel concept, at 11 bar IMEP. Low temperature combustion (LTC) strategies (MK, PCCI, HCCI) are one way researchers are looking to reduce engine-out emissions while maintaining high engine efficiency. SAE 2001-01-0655), and optimizing fuel reactivity (Bessonette et al., Rolf Reitz. SAE 2007-01-0191).
Within the scope of an agreement signed in November 2017 ( earlier post ), Eni and FCA have developed “A20”, a new fuel with a low level of emissions due to its 15% methanol and 5% bio-ethanol alcohol content. An initial test run of five Fiat 500s from the Eni Enjoy fleet in Milan ended successfully a few weeks ago.
The new options would reduce some economic and procedural impediments to clean alternative fuel conversions while maintaining environmental safeguards to ensure that acceptable emission levels from converted vehicles are sustained. Exhaust, Evap, and OBD testing 2. Exhaust and Evap testing + OBD attestation. Intermediate age.
Emissions are also reduced, particularly cold-start hydrocarbon emissions, which are cut by about 25%. Continuously variable valve timing, which GM pioneered for overhead-valve engines, is refined to support the LT1 AFM and direct injection systems to further optimize performance, efficiency and emissions.

The ISX12N and the Cummins L9N are the lowest certified NO x emission engines available in North America. NO x exhaustemissions are 90% lower than the current EPA NO x limit of 0.2 g/bhp-hr, and the engines also meet or exceed the 2017 EPA greenhouse gas (GHG) emission requirements. g/bhp-hr) since 2001.
In addition, this design allows a Variable Nozzle Turbine (VNT) DualBoost turbo to drive ultra-high levels of EGR (exhaust gas recirculation) in line with 2010 US emissions standards that call for 80% reduction in NO x while maintaining the ability to achieve higher horsepower.
Tailpipe emissions of CO 2 from the combustion of ethanol and gasoline are similar on an energy basis—i.e., using ethanol does not affect a vehicle’s tailpipe CO 2 emissions per mile driven. Effects on emissions. Earlier post.). the optimal air/fuel ratio for ethanol blends is lower than for pure gasoline.
In 2001, Railpower launched the first hybrid electric switching locomotive in North America, using battery energy storage, called the Green Goat. First, in the middle of the decade, new rules regarding diesel locomotive emissions will come into effect in North America and the European Union.
Our 2018 product line demonstrates an important milestone in product development for Cummins Westport, creating a move to zero emissions strategy for our customers and industry. The new ISX12N and L9N will be the lowest certified NO x emission engines available in North America. g/bhp-hr) since 2001. g/bhp-hr) since 2001.
CO 2 emissions were reduced to 129 g/km (predecessor: 139 g/km). This reduces harmful emissions, leading in turn to cleaner exhaust gases. Since launching its first CNG vehicle in 2001, Opel has sold more than 70,000 CNG-powered vehicles throughout Europe, including the Zafira, the Astra Caravan and the Combo.
The worst sites in California have demonstrated a 52% improvement in ozone from 1976 to 2010, a 29% improvement in fine particulate matter (PM 2.5 ) from 2001 to 2010, an 84% improvement in carbon monoxide from 1970 to 2009, and a 92% improvement in sulfur dioxide from 1970 to 2009.
Testing was in three steps: Pre-test on highway to determine the maximum temperature of the vehicles T max , measured at the exhaust manifold or turbocharger by driving at the vehicles’ maximum speed (about 180 to 190 km/h). Climate Change Emissions Policy Vehicle Systems' —JRC report.
liter ISL G NZ is the first MidRange engine in North America to receive emission certification from both US Environmental Protection Agency (EPA) and Air Resources Board (ARB) in California to meet the optional 0.02 Exhaustemissions of the ISL G NZ are 90% lower than the current EPA and ARB NO x limit of 0.2 Earlier post.).
The PowerShift transmission helps deliver reductions in fuel consumption and CO 2 emissions, while also providing a more responsive and refined driving experience. with PowerShift has cut CO 2 emissions by 19% to 149g/km, and now achieves an average fuel consumption of 6.4 Compared to the 100PS (99 hp, 74 kW) 1.6-liter
(CWI) announced that its new ISL G Near Zero (NZ) natural gas engine is the first mid-range engine in North America to receive emission certifications from both US Environmental Protection Agency (EPA) and Air Resources Board (ARB) in California that meet the 0.02 g/bhp-hr and also meet the 2017 EPA greenhouse gas emission requirements.
Just as the first RAV4 launched the compact crossover SUV segment 22 years ago, the original Highlander redefined the midsize family SUV when it arrived in 2001. The gas engine employs Variable Valve Timing-intelligent system by Electric motor (VVT-iE) on the intake camshaft, and VVT-i on the exhaust camshaft. The 295-horsepower 3.5-liter
In this scenario, the analysis found that 4,520,000 tonnes of additional CO 2 emissions would be incurred in 2015. The single year of carbon emissions is the equivalent to the annual greenhouse gas emissions of 951,600 passenger vehicles, according to the EPA’s equivalency calculator. billion gallons in 2015). Source: ERC.
Standards under development in these areas include: J1711: Emissions and Fuel Economy Testing. Such procedures will be used during exhaustemissions tests and fuel economy certification tests, and may be used for future “charge economy” certification tests.
BMW TwinPower Turbo technology, which today is already fitted to many gasoline and diesel engines and which will eventually be available for all new engines, is a core technology in the on-going endeavor to reduce both consumption and emissions. Finally, all of the power units have the same “cold” intake and “hot” exhaust sides.
Due to the unit’s high efficiency, CO 2 emissions are substantially lower than in conventional combustion engines, and no other demonstrable exhaust is discharged—i.e., 2001) Solid acids as fuel cell electrolytes. The reformer converts hydrocarbons into hydrogen, CO 2 and heat. The Electrochemical Society Interface.
The Partnership aims to “ accelerate the introduction of advanced truck and bus technologies that use less fuel, have greater fuel diversity, operate more safely, are more reliable, meet future emissions standards, and are cost effective.” The 21CTP was formed in 2001 to reduce fuel usage and emissions in trucks of Classes 3 through 8.
The Isenbüttel site was chosen for this center and construction of a special research center for electric drivetrains began in 2001. The drive configuration gives the zero-emission Audi A7 Sportback h-tron quattro 170 kW of available power—a new level of performance in fuel cell cars.
billion USD in 2001 to 7.11 Jackson Ka, Chairman, Supreme Electronics and GTE commented: “The Indian government’s initiative towards electrification is very encouraging and an important step to help India achieve its goal of reducing harmful emissions. Bilateral trade between India and Taiwan has grown nearly seven-fold from 1.13
