Cummins progressing with lightweight downsized T2B2 diesel for pickup; 40% improvement in fuel economy over gasoline V8

Green Car Congress

Cost of the new engine relative to gasoline baseline. The technical focus over the last year has been on new engine installation and performance assessments. In 2013, the Cummins-led team demonstrated a Tier 2 Bin 5 version of the engine on the dyno, and then on a vehicle, while development of the Tier 2 Bin 2 engine started.

CPT launching water-cooled electric supercharger for commercial diesel engines

Green Car Congress

At the 17 th Supercharging conference this week in Dresden, Controlled Power Technologies (CPT) will launch what it says is the first water-cooled electric supercharger developed for “quasi-continuous” boosting of commercial diesel engines, including those developed for off highway applications. tonnes gross vehicle weight.

New Efficient Supercharger with Variable Drive for Downsized Gasoline Engines

Green Car Congress

Turbo lag can become increasingly intrusive as engines get smaller. Superchargers are mechanically geared to enhance performance at either low or high engine speeds. The need to reduce CO 2 emissions is leading to downsized engines, heavily boosted by turbo- or supercharging. million today to 12 million by 2016.

ICCT: decline in diesel sales will have negligible impact on attainment of European CO2 emission standards

Green Car Congress

The current decline is ales of diesel light duty vehicle in Europe does not put EU CO 2 targets out of reach of automakers, according to a new analysis by the International Council on Clean Transportation (ICCT). In addition, vehicle manufacturers increasingly use electric motors to complement conventional combustion engines in cars.

Study finds highly-turbocharged alcohol-fueled DISI engines could be more efficient than diesels

Green Car Congress

Highly turbocharged alcohol-fueled direct-injection spark-ignition (DISI) engines operated at a high compression ratio could be as or more efficient than diesel engines while also providing advantages of lower vehicle cost, lower emissions and higher power, according to a recent modeling study by Leslie Bromberg and Daniel Cohn at MIT.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. Source: ETH Zürich. Click to enlarge.
