	GM Powertrain Debuts New Engines at SEMA
		GM Powertrain is also showcasing a new Ecotec 2.4 liter engine, which brings both larger displacement and variable valve timing to the Ecotec modular family.
		The new engine's bore is 88 mm and stroke is 98 mm, versus the 2.2 liter's 86 mm bore and 94.6 mm stroke, yielding a total displacement of 2,384 cc versus the original 2.2 liter's 2,189 cc.
		The largest of GM's expanding family of 60° V-6 engines, the 3900 achieves larger displacement via an increase in bore size to 99 mm from the 3500 V-6’s 94 mm — requiring the bore centers to be ofset by 1.5 mm.

	LQ1
		The General Motors 60В° V6 family of engines engines began with the 1978 Buick 3.2 L V6 and continues to be produced today.
		Like the rest of the generation I engines, they were updated in 1985 with larger main journals for durability and MPFI and OBD I. Generation I of the transverse engines ended in 1987.
		GM produced two 3.4 L variants of the 60° block: A normal large-bore OHV descendant of the 3.1 L (the LA1) and an odd DOHC version, the LQ1.

	GM Announces 3900 OHV Engine - XtremeGM.com: GM Owners Community (Site not responding. Last check: 2007-10-13)
		The largest of GM’s expanding family of 60-degree V-6 engines, the 3900 achieves its 3900 cc of displacement via an increase in bore size to 99 mm from the 3500 V-6’s 94 mm — and also incorporates several important new innovations and upgrades.
		Michalski said that to attain the 3.9 liters of displacement Powertrain engineers deemed ideal, the 3900’s larger cylinder bores had to be offset 1.5 mm from the crankshaft center line so that the cylinders did not interfere with the camshaft.
		Although the new 3900 V-6 was designed as a high-output, performance-oriented engine, it hardly foregoes the traits of reliability, durability and refinement that are characteristics of GM Powertrain’s “high-value” engine families.

	The Oakland Press: Business
		Tom Stephens, group vice president in charge of GM's Pontiac-based Powertrain Group, said Thursday the new diesel engine will fill a gap in the company's product portfolio between the smaller diesel engine GM now sells in Europe and large diesel engines that are popular on oversized pickup trucks.
		In addition, it will be GM's first engine to use a NOx after-treatment system with a diesel particulate fi lter to help achieve the Tier 2 Bin 5 and LEV 2 emissions standards, he said.
		GM sells more than 1 million diesel engines annually, with products that offer a range of choices from the small 1.3 four-cylinder diesel engine sold in the Opel Agila and Corsa, up to the 6.6L V-8 Duramax diesel sold in fullsize vans, heavy-duty pickups and medium-duty trucks in the United States.

	Green Car Congress: GM Unveils Opel Antara Twin-Turbo Diesel Concept
		GM simulations calculate that the engine, combined with the six-speed automatic transmission, will give the Antara GTC concept a top speed of more than 210 km/h and an acceleration from zero to 100 km/h in around 8 seconds.
		GM has been working on the twin-turbo technology for several years, first applying it publicly in an earlier engineering study in an Opel Vectra presented at the Essen show in November 2003.
		The mean effective pressure of an engine is average working pressure acting on the pistons during the combustion process—the higher the value, the higher the power output.

		GM's DoD technology works because it means that a consumer can get the power of a 3.9-liter V6 or a 5.3-liter V8 (more applications are undoubtedly coming) but the fuel economy ratings of smaller engines.
		GM's DoD system allows an engine to use maximum power whenever it's needed without any discernable hesitation or pause (test-drives showed that to be true) and then puts half of its cylinders on standby when they're not required.
		The third engine that GM put on display was the 2.4-liter version of its Ecotec family of inline fours.

	Wired 10.08: GM's Billion-Dollar Bet
		GM is the only US automaker developing its own fuel cell in-house: at the company's Warren, Michigan, research facility; at a 300-engineer skunk works near Rochester, New York, that recently expanded by 80,000 square feet; and at a third center in Mainz-Kastel, Germany.
		The engineers knew gasoline fuel cells would be an interim technology on the path to a pure-hydrogen cell, but it would be cleaner and more efficient than a conventional engine and take advantage of the existing gas station infrastructure.
		GM's plug-in electric car, first offered to the public in 1997, could do neither of these things, and so, though it was quick, fun, silent, and nonpolluting, GM pulled it from the market in 1999.

	Fuel Injection Basics - Tech Article - Chevy High Performance Magazine
		GM computers learn as they go, adjusting fuel trim in closed-loop mode based on the oxygen content of exhaust gases, searching continuously for the chemically perfect 14.7:1 air/fuel mixture and storing the required trim for future use.
		GM computers very rapidly and repeatedly trim injection pulse width and observe the result via the O2 sensor, adding or subtracting fuel as necessary to hone in on the chemically perfect air/fuel ratio.
		Engines need the most fuel per power stroke at peak torque under wide-open throttle, since this is the point at which the engine breathes the most air and at which you definitely want a maximum-power air/fuel ratio.

	GM's Reuse Strategy - News by InformationWeek
		Engineers at GM, Ford, and DaimlerChrysler prefer to design new parts, Mixer says, so there needs to be a change in corporate cultures if those companies are to get maximum value out of databases that make it possible to reuse parts.
		GM already has a platform in place to take advantage of the parts models that are or will be stored in the database.
		GM believes that parts reuse will lead to increased quality and fewer recalls when engineers grab parts for which there's good data on reliability.

		At high rev, the pressure would have been too high, causing too much stressed and heat to the combustion chamber, thus may damage the engine.
		Especially at high rev, it generates a lot of friction thus energy loss and prevent the engine from revving high.
		That means the engine becomes lazy to rev (and to thrill you), but at any time you have a lot of torque to access, without needing to change gears frequently.

	GM Displacement Engine Technology - Popular Hot Rodding Magazine
		Had GM elected to apply DOD technology to performance vehicles such as the Corvette, GTO or a future Camaro, there would be far less pressure from corporate average fuel economy (CAFE) to import sub-compacts from outside GM as is the case now.
		All corporate politics aside, the engineers at GM Powertrain have designed yet another mechanical marvel, and it's all due to some remarkably modest changes to the very robust Gen III architecture on which the Gen IV is based.
		The "high value" 60-degree OHV V-6 will become the staple engine in vehicles which typically had the old 3100-, 3400- and more recent 3500-series engines (on which the LZ8 is based).

	GM's 'hands-on' engine whiz: Tom Stephens grew up with grease under his fingernails.
		GM Powertrain comes under the aegis of North American Operations (NAO) and is responsible for all powertrains in North America except for Saturn Corp., with which it has a close relationship.
		Reminding that 4-valve overhead cam (OHC) engines with aluminum blocks and heads - technology to which automakers have stampeded in recent years - have been around since 1919, he argues strongly that there's ample room for longstanding, but technically enhanced, overhead-valve (OHV) pushrod technology, based on where and how the engines are used.
		If GM were to develop a new inline engine, "I'd be in the camp of doing it with OHC technology," he says.

	Maintaining GM Northstar V8 Engine, Larry Carley, Underhood Service, October 2002
		GM recently unveiled its Northstar XV12 concept engine that is physically about the same size as the existing V8 but is capable of producing up to 750 horsepower!
		In model year 2000, GM began using a new high pressure "squeeze" casting process for the lower crankcase to reduce porosity in the aluminum, which may allow oil to seep through and leak (this has been a problem on some engines).
		The engines are factory-equipped with 100,000-mile platinum-tipped spark plugs and five-year/150,000-mile Dex-Cool antifreeze, and use chain-driven cams to eliminate the need to replace timing belts.
