 GM - GMability Education 9-12:Technology - Calculating displacement, or volume of an engine   (Site not responding. Last check: ) Ads for vehicles will often state something like, “It has a 6.0-liter engine.” That measurement is generally called the engine size, and it is calculated based on displacement, the volume of air displaced by the action of the pistons. Calculating the displacement of an engine is exactly the same as finding the volume of a cylinder. The volume of all the cylinders is equal, so to get total displacement, we multiply the volume of one cylinder by the number of cylinders. www.gm.com /company/gmability/edu_k-12/9-12/technology/ice_volume.html   (324 words)

 FE Engine The smallest big-block Ford was the 332 (of 331.8 in³ (5.44 L) true engine displacement) with a 4.0 in (101.6 mm) bore and 3.3 in (83.8 mm) stroke. The 390 in³ (of 389.6 in³ or 6.4 L true displacement) engine, with a bore of 4.05 in (103 mm) and stroke of 3.78 in (96 mm), was the most common FE engine in later application. The medium range of displacement needs was to be met by the 400M engine which was a Cleveland-style block with a raised deck allowing it to use a longer stroke crankshaft and displacing 400 cubic inches (6.55 L). home.comcast.net /~gtscode/femustang/fe_engine.htm   (2430 words)

 2007 Engine Masters Challenge Rules Engines designed and produced by a domestic OEM with distributor-less ignition systems or engines that have been modified to accept a distributor are not allowed. Engines must be equipped with a distributor, ignition box, ignition coil, spark plug wires (with suppression shielding) and related ignition wiring designed for easy connection to the dyno. An engine protested for an external protest and found to be out of compliance with the requirements of the rules will be given to opportunity to make necessary changes to in compliance with the requirements of the rules if the protested motor has made no dyno pulls. www.popularhotrodding.com /enginemasters/0701em_rules   (3788 words)

 Engine Displacement Comparison 306 & 347 - 5.0 Mustang & Super Fords Magazine Though the edict "there is no replacement for displacement" is probably as old as the internal-combustion engine itself (no doubt coined by a racer), the basic philosophy goes back even further. Though bigger is better still applies to engine displacement and power potential, a number of other variables must now be considered. To see what more displacement was worth, we assembled both a 302 short-block and a 347 short-block and took them to the Westech dyno facility. www.mustang50magazine.com /techarticles/18601_engine_displacement_comparison_306_347   (2323 words)

 Ford FE engine at AllExperts In the ongoing development of Ford V8's, the Y-block was soon supplanted by the new Windsor engines (221, 260, 302, 351 cubic inches) in the early 1960's and the MEL was replaced by the 385-series engines in the late 1960's (429, 460 cubic inch versions). The 335-series engines, commonly referred to as Cleveland engines, were designed to replace the largest of the small-block Windsor engines, with the 335 beginning at 351 cubic inches (5.75 L). The medium range of displacement needs was to be met by the 400M engine which was a Cleveland-style block with a raised deck allowing it to use a longer stroke crankshaft and displacing 400 cubic inches (6.55 L). en.allexperts.com /e/f/fo/ford_fe_engine.htm   (2540 words)

 Quasiturbine> Theory> Piston Differences In order to compare different types of engine, one has to get back to basics where the power of a theoretically good engine (which piston and Quasiturbine are, but not the Wankel because of the PV diagram), is proportional to its fuel-mixture intake capability per revolution, and not its displacement. In addition, the average torque of a 4-stroke piston engine does not exceed 15% of the maximum instantaneous torque (which dictates the required engine strength), while for the Quasiturbine the average torque is equal at 90% of the maximum torque, thus illustrating the substantial internal stress reduction and the unique homo-kinetic quality of the Quasiturbine. The Quasiturbine is thus an ideal engine for use in hostile environment (for example, in boat propulsion, the blades of the propeller could be directly welded to the rotor, and the whole engine immersed, which also has the advantage of lowering the center of gravity). quasiturbine.promci.qc.ca /ETheoryQTVersusPiston.htm   (2875 words)

 Quasiturbine> Theory> Engine Problematic Engines fail to be "all in one" compact, low weight, low noise, zero vibration, high torque at low rpm, efficient on a wide power range... Due to this effect, the engine in Beau de Rocha (Otto) cycle opposes to all RPM revolution increase (well known as the engine compression braking) and this intrinsic resistance to speed augmentation is compensated by a constant and important fuel consumption at all time, except at full power. Generally, the engine combustion chamber is a non-desirable parasite volume from the stand point of energy efficiency, since it must be pressurized in pure lost before being able to produce strong forces on the piston and so to make useful mechanical work. quasiturbine.promci.qc.ca /ETheoryEngineProblematic.htm   (2946 words)

 Engine Report Displacement should be taken into consideration when comparing engines because the displacement of an engine directly relates to the amount of power it has. Because the ABA engine was designed to fit into a Golf or Jetta,[53] there isn’t enough clearance between the top of the engine and the hood of the car. The PL is a 16-valve engine and the AWP is a 20-valve engine. www.funksoulkitty.org /Final.htm   (4808 words)

 Saabnet.com Press: Saab Variable Compression Engine The SVC engine is comprised of a cylinder head with integrated cylinders, which is known as the monohead, and a lower portion consisting of the engine block, crankshaft and pistons. However, engine development has now reached the stage at which a new parameter of the combustion process must be optimized to meet future demands for reducing the carbon dioxide emissions and enabling alternative fuels to be used. The compression ratio of an engine is the piston displacement volume plus the volume of the combustion chamber divided by the volume of the combustion chamberÑin other words, the amount by which the fuel/air mixture is compressed in the cylinder before it is ignited. www.saabnet.com /tsn/press/000318.html   (2321 words)

 Howstuffworks "Basic Engine Parts" The core of the engine is the cylinder, with the piston moving up and down inside the cylinder. In a multi-cylinder engine, the cylinders usually are arranged in one of three ways: inline, V or flat (also known as horizontally opposed or boxer), as shown in the following figures. A car engine is one of the most amazing machines we use on a daily basis. auto.howstuffworks.com /engine2.htm   (1050 words)

 Rotary Performance Technical Articles We all know that these engines are measured by measuring the area of the bore, multiply by the stroke and then multiply by the number of cylinders. The key for comparing the displacement between the 4-cycle engine and the rotary engine is in studying the degrees of rotation for a thermodynamic cycle to occur. For a 4-cycle engine to complete every thermodynamic cycle, the engine must rotate 720° or two complete revolutions of the crankshaft. www.rx7.com /techarticles_displacement.html   (415 words)

 Bikez.com - Motorcycle dictionary The diameter of the cylinder in an engine. The compression ratio of an engine is the ratio of the volume above the piston at the bottom of its compression stroke to the volume above the piston at the top of its stroke. In an engine, the torque is expressed as the force applied multiplied by the distance from the center of rotation. www.bikez.com /jargon   (3021 words)

 RE: A curious question about engine displacement so if 2 engines, one gas and one desil of the same size displacement, were tested then the desil would have more low end torque and gas would have better top end because gas engines can easily rev to 6-8 thousand rpms while a typical desil can rev to about 4000 or so. They have made incredible gains in dsl engines as of late with turbos, intercooling and computer controls, ect., but still not up to the power output of a gas engine. In order to be fair to compare the two fuels, you must also boost the gas engine with the same amount of boost that the dsl has. www.rcuniverse.com /forum/m_1593099/anchors_1604332/mpage_2/key_/anchor/tm.htm   (1733 words)

 Import Rival - General Automotive - How to Calculate Engine Displacement? Engine displacement is the amount of the air and fuel mixture that all of your cylinders can take in during a complete engine cycle: intake stroke, compression stroke, combustion stroke, and exhaust stroke. Calculating your engine displacement is the SAME as finding the volume of a cylinder. To break it down even further, a 6.0L engine pulls in 6.0 liters of the air and fuel mixture while its 8 cylinders are making one full cycle though the engine. www.importrival.com /modules/AMS/print.php?storyid=34   (637 words)

 A curious question about engine displacement Technically, since the stroke is the same, and the engine is now over-bored (bore is greater than stroke), the engine should become more higher revving, have more hp, but less torque. but if you think about it a short stroke engine would crank out more rpms because the stroke of the piston is shorter, so that the piston on a shorter stroke engine wouldnt have to move as far for each stroke(gaining rpms but loosing torque). That being said, one would assume that when increasing displacement, you are only increasing bore and leaving the stroke the same (as in the.26) - then the engine would in essence create the same torque as before, as you technically decreased the stroke of the engine in relation to its size. www.rcuniverse.com /forum/m_1593099/printable.htm   (2147 words)

 More about engine displacement   (Site not responding. Last check: ) The displacement of most normal car engines is between 1.5 and 4.0 liters. So a 2.0 liter engine is roughly half as powerful as a 4.0 liter engine. You can get more displacement in an engine either by increasing the number of cylinders or by making the combustion chambers of all the cylinders bigger (or both). www.wam.umd.edu /~clehman/cs3/displacement.html   (78 words)

 Howstuffworks "What does "2.4 liter" mean in the context of an engine?" If you were to turn the crankshaft of this engine through two complete revolutions, the four pistons would inhale a total of 3.3 liters of air. And it is also possible to create a 1-liter engine that is highly tweaked to give absolutely the best performance possible from the gasoline it receives. And these two engines could have the same horsepower rating even though one has 10 times more displacement than the other. auto.howstuffworks.com /question685.htm   (535 words)

 Stroker Engine Build - Tech Articles - Mustang Monthly Magazine Greater displacement is likely the cheapest way to pull power from a given block–and–cylinder head combination. As its name implies, a stroker is where we increase engine displacement by increasing piston stroke. Stroker kits make obtaining displacement a no-brainer, because all you provide is the block--and in many cases, the manufacturer provides the already machined block, making short work of displacement. www.mustangmonthly.com /techarticles/17460_stroker_engine_build   (699 words)

 MSGCVWC VW Tech - Engine Displacement The power of a Volkswagen engine can be increased relatively easily by replacing the pistons and cylinders (increasing the bore) with a set having a larger displacement or CCs (Cubic Centimeters). The vast majority of VW engines these days are the stock 1600cc with a bore of 85.5mm. For those of you who want big horsepower, replacing the crankshaft with one having a longer stroke (referred to as a "Stroker" engine) is the way to go and results in an engine displacement up to 2.4 liters. www.msgulfcoastvwclub.org /TechPages/Tech6.html   (404 words)

 Green Car Congress: The G6 Giveaway, Fuel Economy and the Competition   (Site not responding. Last check: ) The first is just the quick ratio of horsepower to engine displacement (the number (3.5L) used to indicate the combined volume of the portion of the cylinders into which the air/fuel mixture flows during the engine cycle). But GM has slated this engine model (named the 3900 or LZ8) to be the first V6 with Displacement on Demand (DoD)—the feature that deactivates three of the six cylinders under certain driving conditions to reduce fuel consumption. Enlarging the 3900’s displacement by 400 cc actually improves its overall fuel economy because the larger displacement translates to a greater amount of time the engine can operate in its ultra-efficient three-cylinder mode. www.greencarcongress.com /2004/09/the_g6_giveaway.html   (1297 words)

 Clevite Engine Parts This engine building competition is actually a demonstration project to show the viability of ethanol-based fuels in automotive engine applications. “And while much of our engineering work is at the OE level, we have long worked with AERA and the engine remanufacturing industry to assure that vehicular engines work well during their “second life” after overhaul. In addition to being an exhibitor at the RPM Show and Official Engine Parts Supplier for the E85 Power Shootout, Clevite will also sponsor famed drag racer Shirley Muldowney who will be a keynote speaker and will also be available for interviews and brief individual discussions on the show floor. www.engineparts.com /newsroom_detail.asp?id=134   (569 words)

 1980 Avanti II - Engine Displacement - AOAI Forums   (Site not responding. Last check: ) GM made 400ci engines from about 1970 to as late as 1980. One way to tell a 400ci block is that nearly all of them have casting provisions for 3 freeze plugs on each side rather than the 2 that are normal on smaller displacement engines, although only 2 freeze plugs were machined on some of the 400ci blocks (but, see below). It's always possible, of course, that the engine currently in the car is not original to the car, in which case the casting and stamped numbers might help identify it. www.aoai.org /forums/index.php?showtopic=309   (586 words)
