Cost of the new engine relative to gasoline baseline. So far, Ruth noted, the new engine has achieved target engine-out emissions (EOE), performance and fuel economy; aftertreatment catalyst performance has met or exceeded the targeted conversion rates, enabling an increased allowance on engine out HC. Earlier post.). Source: Cummins.
The researchers assessed the gaseous, particulate, and genotoxic pollutants from two current technology gasoline direct injection vehicles when tested in their original configuration and with a catalyzed gasoline particulate filter (GPF). liter downsized turbocharged centrally-mounted direct injection engine. Johnson, David R.
CPT says that the RegEnBoost system enables a typical family-sized car to achieve less than 100 g/km CO 2 with a 1-liter gasoline engine, but when required can offer the same lively performance and in-gear acceleration of a 2-liter naturally aspirated powertrain.
Operating range of 2-stroke CAI fueled with gasoline, E10 and E85. Accordingly, the processes have been extensively researched over the last decade and adopted on prototype gasoline engines (e.g., Zhang et al. 2013a) Click to enlarge. Controlled autoignition (e.g., Controlled autoignition (e.g., GM’s ongoing work, earlier post ).
The report, Assessment of Technologies for Improving Light Duty Vehicle Fuel Economy estimates the potential fuel savings and costs to consumers of available technology combinations for three types of engines: spark-ignition gasoline, compression-ignition diesel, and hybrid.
Internal combustion engines have been significantly improving in the past decade, after the adoption of technologies such as Gasoline Direct Injection, mild electrification, downsizing and turbocharging. The OSU EcoCAR prototype vehicle features an extended-range electric architecture with a downsized 1.8L
mpg US) (99 g/km CO 2 )—more efficient than any previous Golf with a gasoline engine. The new TSI engine also offers the highest specific torque of any large-scale production series gasoline engines: 200 N·m per liter displacement. The turbocharged gasoline engine with its 10.5:1 l/100 km (54.7
Continental will present an innovative close-coupled annular catalytic converter that supports near-complete NO x conversion in downsized turbocharged gasoline engines at the 37 th Vienna Motor Symposium next week. For downsized turbocharged gasoline engines, this presents two challenges. Click to enlarge.
Relative changes in vehicle energy efficiency (VEE) (km/MJ) on ethanol/gasoline blends over those on gasoline for different blending levels. Several recent highly cited LCAs that have incorporated vehicle efficiency differences between gasoline and ethanol/gasoline blends could potentially be misleading. Click to enlarge.
The resulting higher BMEP levels allow downsizing of the engine at equivalent vehicle performance. The vehicle owner will realize high fuel economy because gasoline, with its greater eating value per volume, is the fuel that is primarily used for most driving modes. E85 DI + gasoline PFI engine in a pickup truck.
technology and there is progress on the economic conversion of biomass to. There is no strong advocacy for methanol (unlike ethanol) as a transportation fuel; therefore, they said, it has been displaced by ethanol as oxygenate of choice in gasoline blends. The toxicity (mortality) is comparable to or better than gasoline.
The ICCT team—John German and Aaron Isenstadt—concluded that diesels have and will retain two significant advantages over gasoline engines: significantly better fuel economy and cargo hauling and towing ability. Diesels offer a promising pathway for compliance and another option in manufacturers’ toolboxes. ”. E-boost and 48V.
liter hybrid system; and new 4WD systems—one for gasoline-engined cars, one for hybrids—based on the Toyota New Global Architecture (TNGA). Conversion to wider gear ranges. Shift responsiveness has improved through downsizing of the pulley and reduction of inertia by 40%. liter class.
The adaptability and capability of the MPC5676R make it suited for a variety of powertrain control applications, including diesel, gasoline and natural gas engines and hybrid electric and plug-in electric vehicles. DI requires significant MCU performance (36,000 conversions/sec/cylinder to overcome the mechanical limitation.
Comparison of fuel consumption of Omnivore, homogeneous Gasoline Direct Injection (GDI) and Spray-Guided GDI engines. The first testing phase of Lotus Engineering’s Omnivore variable compression ratio, flex-fuel direct injection two-stroke engine ( earlier post ) has been successfully completed on gasoline. Click to enlarge.
This downsizing enables lower fuel consumption, accompanied by low emissions and optimum weight. Conversely, intervention will be stopped if the driver carries out an evasive maneuver, takes his or her foot off the brake pedal or presses the accelerator pedal. The engines attain both a high specific power output and high torque.
Conversion to dual overhead cam with dual cam phasing: as applied to overhead valves designed to increase the air flow with more than two valves per cylinder and reduce pumping losses. Combustion restart (CBRST): can be used in conjunction with gasoline direct-injection systems to enable idle-off or start-stop functionality.
Ford’s turbocharged, gasoline direct injection EcoBoost engines are targeted to play a significant near-term role in Ford’s efforts to reduce fuel consumption by enabling downsizing. The cold-start period constitutes the majority of engine emissions due to zero or low conversion efficiency of the aftertreatment system.
Thrust 1 builds on the significant amount of work carried out over the past several decades, focused on building advanced boosted, downsized, and downspeeded spark ignition engines. Co-Optima is definitely not seeking to develop new conversion pathways, but is relying on what has already been done. Gasoline Compression Ignition (GCI).
The two gasoline (TSI) and three diesel (TDI) engines are four-cylinder, 16-valve engines feature turbocharging and direct fuel injection. In the large Sharan the downsized engine consumes on average 6.4 The first generation Sharan made its debut in Geneva in 1995; between 1995 and 2015 more than 800,000 Sharans were sold worldwide.
Several after-market companies have done PHEV conversions of the Ford Escape hybrid and one has done a retrofit of the F-150 pickup -- see Where PHEVs Are and ICE-Conversions.) Company says its focusing on gasoline and hydrogen. Has shown some concept fuel-cell PHEVs. First Escape PHEV delivered to SCE Nov 2007; 20 in 2008-2009.
two split pairs) operating in a 2004 Chevrolet Cavalier would consume 25% less fuel under the FTP (Federal Test Procedure) than the comparable standard gasoline engine, while matching power and torque. With turbocharging, we can have some huge gains, we can downsize the engine and produce very big power. —Sal Scuderi.
TFSI gasoline turbocharged direct injection engine for the first time at the Vienna Motor Symposium this week. This also addresses particulates from gasoline direct injection. Audi introduced its new series-production 2.0 The four-cylinder engine delivers 140 kW (190 hp) and 320 N·m (236.0 Stansfield, P., and Freeland, P.
Though the PHEV combines the two types of energy and power, it is not merely a temporary “transition” between gasoline and diesel cars to pure electric cars. Since it can refuel from a standard household outlet and from a gasoline station, it needs no new infrastructure. It is much more than that. Engineering Advantages of the PHEV.
Achates Power says that its 2-stroke OP engine offers higher best point brake thermal efficiency than diesel or gasoline engines. The A48 engine in Achates’ test cell was developed on an 80mm bore, Johnson said; the TARDEC application will be a bit downsized. Source: Achates Power. Click to enlarge. Earlier post.).
