Study finds high exhaust temperatures within NTE operation for heavy-duty diesels with aftertreatment systems contribute to high nanoparticle concentrations

Green Car Congress

The transient results illustrate the gradual formation of the nucleation mode particles with continuous increase in exhaust temperatures. Diesel particulate filters (DPF) and urea-based selective catalytic reduction (SCR) exhaust after-treatment systems thus have emerged as feasible strategies to meet the 2010 USEPA regulations.

Toyota introduces new XSE Hybrid Grade Camry

Green Car Congress

for XSE grade, which uses a dual-outlet exhaust). Most AWD grades have 202 hp, while the Camry XSE AWD grade has 205 hp with dual exhaust. A variable cooling system, variable oil pump and a cooled exhaust gas recirculation (EGR) system all contribute to the engine’s high thermal efficiency and outstanding fuel economy.

Japan automakers going slow with biodiesel; JAMA maintains stance on B5 as maximum for now

Green Car Congress

PME= palm oil methyl ester, RME = rapeseed methyl ester, SME = soy methyl ester, WME = waste cooking oil methyl ester, FTD = Fischer-Tropsch diesel, HBD = hydrogenated biodiesel. JAMA bases its postion on the results of study from the Japan Auto-Oil Program subsidized by Japan’s Ministry of Economy, Trade and Industry (METI).

Santa Monica signs 5-year deal with Clean Energy for renewable LNG for bus fleet; deploying CWI Near-Zero NOx engine

Green Car Congress

Crankcase emissions are captured and redirected through the CCV filter, where oil is removed, before sending the gases back to the intake manifold to be reintroduced to the combustion chamber. This technology was developed to meet the stringent 2010 EPA emission requirements and was introduced with the ISL G in June 2007.

Volkswagen’s 3rd-gen Golf TDI BlueMotion rated at 73.5 mpg US; 15% better than predecessor

Green Car Congress

Volkswagen launched the first generation of the Golf BlueMotion in 2007.At Among other modifications, they integrated a 6 th gear with a longer ratio for lowering the torque; moreover, the gearbox works with a new fuel-efficient oil featuring a low viscosity, which heightens its effectiveness. l/100 km (73.5 l/100 km (52.3

Toyota, Hino and Showa Shell to Test FT Diesel and Renewable Diesel Blend in Hybrid Transit Bus

Green Car Congress

(SSSKK) plan to begin trials on 1 July of a diesel-electric hybrid transit bus fueled by a mixture of Fischer-Tropsch diesel (FTD)—specifically, Shell’s gas-to-liquids (GTL) fuel—and hydrogenated vegetable oil (HVO), a type of renewable diesel offering similar characteristics to FTD.

Faurecia takes 21.2% stake in Amminex A/S; focus on ASDS gaseous SCR system for NOx reduction

Green Car Congress

The Amminex ASDS is a gaseous Selective Catalytic Reduction (SCR) system—an alternative to liquid SCR systems—which delivers very precise amounts of ammonia from solid state storage (ammine complexes) to a catalyst in the exhaust line. Ammonia storage and delivery systems for NO x aftertreatment (DEER 2007 poster).
