Gravely K Wiring Diagram.The Modular engine received the name from its design and sharing of certain parts among the engine family, starting with the 4.

The name was also derived from a manufacturing plant protocol, "Modular", where the plant and its tooling could be changed in a few hours to manufacture different versions of the engine family. Modular engines used in Ford trucks were marketed under the Triton name from — while the InTech name was used for a time at Lincoln for vehicles equipped with DOHC versions of the engines.

The engines were first produced in Romeo, Michigan then additional capacity was added in Windsor, Ontario. In the early s, then-Ford Motor Company chief operating officer Donald Petersen challenged Ford's vice-president of design, Jack Telnackand his staff to come up with new vehicle designs that they could take pride in. The result was an abandonment of the boxy styling that had dominated Ford products for years and the adoption of sleeker, more aerodynamic designs like that used for the highly successful Ford Taurus.

In the second half of the s, Petersen, now chief executive officer, sought to update Ford's decades-old V8 architectures, challenging Ford senior engineer Jim Clarke to do for Ford's V8s what Jack Telnack did for Ford's vehicle design.

The objective was to develop a new V8 engine that would surpass Ford's earlier V8s in every meaningful way, from power and efficiency to emissions performance and smoothness of operation.

Clarke and his engineers studied engine designs from major European and Japanese automakers and sought to develop a V8 that was technologically advanced and power-dense, yet also dependable with no major service required beforemiles of use. This square configuration was chosen primarily for its positive noise, vibration and harshness characteristics. The engine would utilize features such as a chain-driven, single-overhead camshaft valvetrain with roller finger followersa deep-skirt cast-iron block construction and cross-bolted main bearingsall benefitting long-term durability.

In the interest of reducing overall engine weight, aluminum-alloy heads and pistons would be standard and all major engine accessories would be mounted directly to the block, resulting in a more complex block casting but eliminating the need for heavy mounting brackets. Tight construction tolerances were used in shaping the engine's cylinder bores with narrow piston rings fitted to the engine's pistons.

This would serve to improve engine efficiency through reduced friction and reduce the engine's oil consumption, while also promoting cleaner emissions.

Perhaps the most significant aspect of the new engine's design was the number of variations of the engine that could be made to suit different needs. This resulted in the creation of an entire family of engines consisting not only of designs utilizing single- or dual-overhead camshaft configurations, different displacements and different block materials, but also different cylinder counts.

In addition to the various eight-cylinder engines produced, ten-cylinder engines eventually entered production. Six-cylinder derivatives were also explored, though never built. With the wide array of engine configurations possible within this architecture, Ford developed a new, modular tooling system for producing different engines quickly and efficiently in the same factory.

Referring to this method of production, the name Modular was given to the new engine family. Three years later, in the third quarter ofthe first Modular engine, a 4. To the credit of Jim Clarke's engineering team, the new V8 engine in the Town Car compared favorably to its pushrod -based predecessor.

In spite of having a smaller displacement, the 4. Following the Modular V8's debut in the Town Car, engines using the Modular architecture would go on to replace older V8 designs in Ford products, eventually becoming Ford's chief gasoline V8 and V10 architecture. The engines were also offered with both aluminum and cast iron blocks, depending on application. The 4. Deck height for the 4. Cylinder bore spacing measures 3. All Modular V8s, except for the new 5.

At the risk of losing credibility with our readers assuming I had any to begin with! I've done general maintenance, bodywork, welding, complete paintjobs, and even rebuilt a couple of automatic transmissions, but I've never taken an engine apart and put it back together—until now.

People I've revealed this to usually have the same reaction: Couldn't you have chosen an easier engine to build than the 4. My response is always the same and I hope I don't sound smug when I say it : Building this engine wasn't that hard. I mention this potentially embarrassing truth not as a means of publicly patting myself on the back but rather to inspire our readers. If I can put together an overhead cam 4. To my relief, it started and ran once I got it back in the car.

It runs even better now with at least 4, miles of daily driving and almost 30 full power pulls on Westech's chassis dyno. No oil loss, no scary sounds, and best of all, it makes nearly 70 more horsepower and 50 more lb-ft of torque than before, thanks to Trick Flow Specialties Top End Kit for 2V Modular Ford engines. Don't be fooled by this car's two extra doors; this same build will work for any SOHC 4.

I've come across a lot of rumors floating around online about mod motor cams being installed as many as 4 degrees advanced or retarded from the factory. Wanting to verify this, I checked my engine's cam timing before removing the cylinder heads.

We won't document the entire cam timing test process here, as we've done about half a million cam timing articles in the past 58 years. The mod motor's overhead cam arrangement only adds a slight twist to the process in this boilerplate article. I brought the stock heads and the new Trick Flow heads to Westech for flow bench testing. The difference is dramatic. There is a lot of potential in these Trick Flow castings.

Stock 4. The engine fired on the second crank and ran surprisingly well. After fixing the previously mentioned oil leaks from the gallery plugs in the cylinder heads and fixing an unrelated wiring nightmare under the dashmy car felt really strong running on Blue Oval Chips' programming for the Mercury Marauder MAF installed in our June '11 issue.

As a result, my car is now making 70 more horsepower and nearly 50 more lb-ft of torque. The torque band is much flatter than stock, as well, making about lb-ft from 3, rpm all the way to 5, rpm. The car feels much more powerful and a lot more fun to drive.

We'll have some dragstrip numbers to back up these horsepower figures soon. The secret to our 4. Changing the angle of the intake valve provides a better path into the cylinders. It also eliminates piston-to-valve clearance problems very common to SOHC 4.

With its valve arrangement, Trick Flow says lift of up to 0. Every engine builder we've checked with says Trick Flow's heads—with CNC-shaped chambers and as-cast intake and exhaust runners—will outflow any ported factory cylinder head, and our gains of 70 hp to the rear wheels is right inline with what other Trick Flow customers are seeing.

While we're still breathing through the car's stock intake and tailpipes, we know there is more potential in these heads, especially at higher engine speeds. We're looking at intake combinations and possibly a power-adder to see how much more we can wring out of these things.

Note in the chart above that the best naturally aspirated combination may be an early non-power- improved block and Trick Flow's 38cc chamber heads.Diagram Base Website Full Edition. What is phase diagram? This is a structure which aids the chemist to know the properties of the different components of the compound.

The phase diagram is also known as single phase diagram, double stage structure, or fluid phase diagram.

The diagrams used in phases include molecular disturbance, solid state phases, molecular bonding, and ionic liquids. The molecular splitting phase indicates the separation of molecules into individual ions. Solid-state phases reveal the bonds of electrons and molecular weights. In the molecular level, the liquid phase diagram is used to show the formation of molecules like amino acids. At the atomic level, it depicts the formation of large atoms and atoms.

There are three distinct kinds of stages; these will be the solids, liquids, and aqueous. When studying stage diagrams, one can find out about chemical bonding, that is the process through which molecules of two different substances bond together. When studying this, it is necessary to be aware that the bond between the metal and the other component has little to do with the solubility of these metals. It is easier to study stage diagrams if the two components are at room temperature.

This is due to how the bonds between the components form obviously, while the components are cold. A phase diagram can also be used in the component classification. When this is done, the three components which are common to a lot of people are broken down in to two classes, and these are the alkali metals and alkaline earth metals. Theelements which are important to modern life, such as hydrogen and oxygen, are split into two groups, for example alkaline earth metals and alkaline earth materials.

When analyzing the phases, it's crucial to remember that every element has a exceptional melting point, and it is necessary to understand every element's chemical composition prior to determining its place in the phase diagram. The phase diagram aids a chemist in figuring the process that the molecules undergo during a response. For example, the diagram tells the chemist how a way of sodium metal disagrees with an acid solution. The element participates in the acid to produce an acid, which then reacts with the component, making a dissociated metal.

The phase diagram may be used to help understand the behaviour of organic molecules, such as polymers, polysaccharides, and starch, which are all important to many plants and animals. For example, the phases of glucose supply information concerning the behavior of crystals that form at the molecular level. User Blog.
