What this domain used to publish
With an established partnership, you and AED can take our optimized prototype engine(s) from the lab to the production line.
Eco-Diesel 22T and 24TS 4-cylinder, 4-valve all aluminum direct injected turbo/supercharged diesel engine.
This engine was built from converting the GM high performance (260 hp) Ecotec gasoline engine to an advanced diesel variant using commercial-off-the-shelf (COTS) Bosch common rail fuel injection, high efficiency VNT turbocharger, and custom electronic engine management.
It features variable compression ratio (variable valve timing) with brake thermal fuel efficiency over 42%; high power density (approx.
How the documents describe the case
(c) Except as specified in this section, engines certified under this section must meet all the requirements that apply under 40 CFR part 1039 or 1048 instead of the comparable provisions in this part.
Before shipping engines under this section, you must have written assurance from vehicle manufacturers that they need a certain number of exempted engines under this section.
In your annual production report under 40 CFR 1039.250 or 1048.250, count these engines separately and identify the vehicle manufacturers that will be installing them.
Treat these engines as part of the corresponding engine family under 40 CFR part 1039 or part 1048 for compliance purposes such as testing production engines, in-use testing, defect reporting, and recall.

fic In 1986, initial test with a high speed electronic fuel control produced BSFC values to 0.51.
In fiscal year 1987, BSFC was reduced to 0.46, this through application of validated combustor cones and optimization of the electronic fuel control system.
The overall BSFC goal is 0.35 at 160 horsepower and 8000 rprn.
To achieve this goal turbocompounding, adiabatic components, and a lightweight rotor, with reduced friction, will be required.
