    Terms You Might Want To Know

    Rebuilt
    Unit is reconditioned by cleaning, inspection and replacement of severely worn or broken parts. Serviceable parts are reused within manufacturer's acceptable wear limits. Parts are not automatically replaced without regard to condition.

    Remanufactured / New
    The component is restored to the manufacturer's original performance and dimensional specifications, with updates as applicable. Most wearable parts are replaced without regard to condition. A remanufactured product has replacement parts that are new and made in the same production processes as original equipment. Testing a remanufactured product is performed to manufacturer specifications and original production standards.

    Cylinder
    A cylinder is a round hole through the block, bored to receive a piston. All automobile engines, whether water-cooled or air-cooled, four-cycle or two-cycle, have more than one cylinder. (Four, six, or eight cylinders are the most common. The three-cylinder cars are also becoming more common.) These multiple cylinders are arranged in-line, opposed (flat), or in a V.
    The V-type of engine has two rows of cylinders at (usually) a ninety-degree angle to each other. In-line engines have the cylinders arranged, one after the other, in a straight line. Different configurations have different smoothness and manufacturing cost characteristics that make them more suitable in some vehicles.

    Spark Plug
    The spark plug supplies the spark that ignites the air/fuel mixture so that combustion can occur. The spark must happen at just the right moment for things to work properly.
    Combustion Chamber
    The combustion chamber is where the air-fuel mixture is burned. The location of the combustion chamber is the area between the top of the piston at what is known as TDC (top dead center) and the cylinder head. TDC is the piston's position when it has reached the top of the cylinder and the center line of the connecting rod are parallel to the cylinder walls.

    Piston
    The piston converts the potential energy of the fuel into the kinetic energy that turns the crankshaft. The piston is a cylindrical shaped hollow part that moves up and down inside the engine's cylinder. It has grooves around its perimeter near the top, where rings are placed. The piston fits snugly in the cylinder.
     
    Pistons perform several functions.
    Pistons transmit the driving force of combustion to the crankshaft. This causes the crankshaft to rotate. The piston also acts as a moveable gastight plug that keeps the combustion in the cylinder. The piston acts as a bearing for the small end of the connecting rod. Its toughest job is to get rid of some of the heat from combustion and send it elsewhere.
    The piston head, or "crown", is the top surface against which the explosive force is exerted. It may be flat, concave, convex, or any one of a great variety of shapes, to promote turbulence or help control combustion. In some, a narrow groove is cut into the piston above the top ring to serve as a "heat dam" to reduce the amount of heat reaching the top ring.

    Wrist Pin
    The wrist pin connects the piston to the connecting rod. The connecting rod comes up through the bottom of the piston. The wrist pin is inserted into a hole (about half way up) that goes through the side of the piston, where it is attached to the connecting rod.

    Piston Rings
    Piston rings provide a sliding seal between the outer edge of the piston and the inner edge of the cylinder. They are used to provide an "air tight ft. The rings serve two purposes:

    • They prevent fuel/air mixture and exhaust in the combustion chamber from leaking into the sump during compression and combustion.                                                                                     
    • They keep oil in the sump from leaking into the combustion chamber, where it would be burned and lost.

    Most cars that "burn oil" and have to have a quart added every 1,000 miles are burning it because the engine is old and the rings no longer seal things properly.

    Timing Belt / Chain
    The automobile engine uses a metal timing chain, or a flexible toothed timing belt to rotate the camshaft. The crankshaft drives the timing chain/belt. The timing chain or timing belt is used to "time" the opening and closing of the valves. The camshaft rotates once for every two rotations of the crankshaft.

    The Cylinder Head
    The cylinder head is the metal part of the engine that encloses and covers the cylinders. Bolted on to the top of the block, the cylinder head contains combustion chambers, water jackets and valves (in overhead-valve engines). The head gasket seals the passages within the head-block connection, and seals the cylinders as well.

    Push Rods
    Push Rods attach the valve lifer to the rocker arm. Through their centers, oil is pumped to lubricate the valves and rocker arms.

    Flywheel
    The flywheel is a fairly large wheel that is connected to the crankshaft. It provides the momentum to keep the crankshaft turning, without the application of power. It does this by storing some of the energy generated during the power stroke. Then it uses some of this energy to drive the crankshaft, connecting rods and pistons during the three idle strokes of the 4-stroke cycle. This makes for a smooth engine speed. The flywheel forms one surface of the clutch and is the base for the ring gear.

    Harmonic Balancer (Vibration Damper)
    The harmonic balancer, or vibration damper is a device connected to the crankshaft to lessen the torsional vibration. When the cylinders fire, power gets transmitted through the crankshaft.  The front of the crankshaft takes the brunt of this power, so it often moves before the rear of the crankshaft. This causes a twisting motion. Then, when the power is removed from the front, the halfway twisted shaft unwinds and snaps back in the opposite direction. Although this unwinding process is quite small, it causes "torsional vibration." To prevent this vibration, a harmonic balancer is attached to the front part of the crankshaft that's causing all the trouble. The balancer is made of two pieces connected by rubber plugs, spring-loaded friction discs, or both.

    When the power from the cylinder hits the front of the crankshaft, it tries to twist the heavy part of the damper, but ends up twisting the rubber or discs connecting the two parts of the damper. The front of the crank can't speed up as much with the damper attached; the force is used to twist the rubber and speed up the damper wheel. This keeps the crankshaft operation calm.

    Crankshaft
    The crankshaft converts the up and down (reciprocating) motion of the pistons into a turning (rotary) motion. It provides the turning motion for the wheels. It works much like the pedals of a bicycle, converting up-down motion into rotational motion. The crankshaft is usually either alloy steel or cast iron. The crankshaft is connected to the pistons by the connecting rods. Some parts of the shaft do not move up and down; they rotate in the stationary main bearings. These parts are known as main journals. 

    Main Bearings
    The crankshaft is held in place by a series of main hearings. The largest number of main bearings a crankshaft can have is one more than the number of cylinders, but it can have one less bearing than the number of cylinders. Not only do the bearings support the crankshaft, but one bearing must control the forward-backward movement of the crankshaft. This bearing rubs against a ground surface of the main journal and is called the "thrust bearing."

    Connecting Rod
    The connecting rod connects the piston to the crankshaft. It can rotate at both ends so that its angle can change as the piston moves and the crankshaft rotates. The upper end has a hole in it for the piston wrist pin and the lower end (big end) attaches to the crankshaft. Connecting rods are usually made of steel, although some are made of aluminum.

    Connecting Rod Bearings
    Connecting rod bearings are inserts that ft into the connecting rod's lower end and ride on the journals of the crankshaft.

    Valve Lifter (Tappet)
    The valve lifter is the unit that makes contact with the valve stem and the camshaft.  It rides on the camshaft.  When the cam lobes push it upwards, it opens the valve.

    Valve Ports
    Valve ports are openings in the cylinder head. Intake ports let the fuel mixture into the cylinder head, and exhaust ports let the exhaust out.

    Valves
    The valve's job is to open and close the valve ports. If the ports were always open, the fuel exploded in the combustion chamber would leave through the ports. The explosion has to be kept in the combustion chamber to push the piston down. The valves are set up to open and close at exactly the right moment. One lets the fuel mixture in and closes. After the fuel explodes and pushes the piston down, the other valve lets the exhaust out.

    Valve Stems / Guides
    The valves are usually held in an upright position by the valve stem. The valve stem is the long straight side of the valve, like the stem of a flower. Valve guides are holes that are bored in the cylinder head for the valve stems. Worn valve guides allow oil to enter the combustion chamber and cause blue smoke in the exhaust.

    Valve Springs
    The valve springs keep the valves closed tightly against their seats until the valve is opened by the cam.  After the cam turns (releasing pressure), the valve spring close the valves.

    Valve Seals
    The valve seal is a unit that goes over the end of the valve stem. It keeps excess oil from getting between the valve guide and the valve stem.

    Rocker Arms
    Rocker arms are used to transmit force from cam to valve. Riding on a cam on the camshaft, rocker arms direct the upward motion of the lobe of the cam into an opening motion of the valve stem.

    Push Rods
    Push Rods attach the valve lifer to the rocker arm. Oil is pumped through their centers to lubricate the valves and rocker arms.

    Camshaft
    The camshaft is a round shaft with "lobes" (specially formed bumps) which is driven by the timing belt or timing chain. It, directly or through "lifers" and "pushrods", opens and closes the fuel and exhaust valves. The camshaft turns at one-half of the crankshaft speed. It is supported by bearings located in the front and rear of the crankcase.

    Overhead Camshaft - OHC
    Some engines have the camshaft mounted above, or over, the cylinder head instead of inside the block (OHC - overhead camshaft engines). This arrangement has the advantage of eliminating the weight of the rocker arms and push rods.

    Dual Overhead Camshaft - DOHC
    The double overhead camshaft (DOHC) is the same as the overhead camshaft, except that there are two camshafts instead of one.

    Overhead Valve - OHV
    In an overhead valve (OHV) engine, the valves are mounted in the cylinder head, above the combustion chamber. Usually this type of engine has the camshaft mounted in the cylinder block, and the valves are opened and closed by push rods.

    Multi-valve Engines
    All engines have more than one valve. Multi-valve refers to the fact that this type of engine has more than one exhaust or intake valve per cylinder.

    Valve Cover
    The valve cover covers the valve train. The valve train consists of rocker arms, valve springs, push rods, lifters and cam (in an overhead cam engine). The valve cover can be removed to adjust the valves. Oil is pumped up through the push-rods and dispersed underneath the valve cover, which keeps the rocker arms lubricated. Holes are located in various places in the engine head so that the oil re-circulates back down to the oil pan. For this reason, the valve cover must be oil-tight; it is often the source of oil leaks.

    Oil Pump
    The oil pump is used to force pressurized oil to various parts of the engine.

    Oil Seals
    Oil seals are rubber and metal composite. They are generally mounted at the end of the shafts.  They are used to keep fluids, such as oil, inside. These seals flex to hold a tight fit around the shaft that comes out of the housing, and don't allow any fluid to pass.

    Oil Filter
    Oil filters are placed in the engine's oil system to strain dirt and abrasive materials out of oil.

    Oil Passages
    Within the engine is a variety of pathways for oil to be sent to moving parts. These pathways are designed to deliver the same pressure of fresh lubricating oil to all parts. If the pathways become clogged, the affected parts will lock together. This usually destroys parts that are not lubricated, and often ruins the entire engine.
    The oil passages are cleverly drilled into the connecting parts of the engine, which allows the highly mobile ones (like the pistons) to have ample lubrication. Originating at the oil pump, they flow through all of the major components of the engine. In the case of pistons and rods, the passages are designed to open each time the holes in the crankshaft and rods align.

    Oil Pan
    At the bottom of the crankcase is the container containing the lifeblood of the engine.  Usually constructed of thin steel, it collects the oil as it flows down from the sides of the crankcase. The pan is shaped into a deeper section, where the oil pump is located. At the bottom of the pan is the drain plug, which is used to drain the oil. The plug is often made with a magnet in it, which collects metal fragments from the oil.

    Gaskets
    Gaskets and seals are needed in your engine to make the machined joints snug, and to prevent fluids and gasses (oil, gasoline, coolant, fuel vapor, exhaust, etc.) from leaking. Gaskets made of steel, copper and asbestos are used between the cylinder head and engine block.  Because the engine expands and contracts with heating and cooling, it is easy for joints to leak, so the gaskets have to be soft and "springy" enough to adapt to expansion and contraction.  They also have to make up for any irregularities in the connecting parts.

    Horsepower
    Horsepower is a unit of power for measuring the rate at which a device can perform mechanical work. Its abbreviation is hp. One horsepower was defined as the amount of power needed to lift 33,000 pounds one foot in one minute.

    The Block
    The engine cylinder block or "block" is cast in one piece. Usually, this is the largest and most intricate single piece of metal in the automobile.  Even when the cylinders, cylinder heads, or cylinder sleeves are separate pieces, the crankcase is still the largest single part in the engine. Almost all of the engine parts are attached to the crankcase, directly or indirectly. The crankcase houses the crankshaft and often the camshaft, as well. With the oil pan, which goes on the lower surface of the crankcase, it forms an oil-tight housing in which the rotating and reciprocating parts operate. The cylinder block is laced with coolant passages, called the "water jacket". The cylinder block is usually made of high grade cast iron, with alloys to improve wear of the cylinders, but many are aluminum. Plastic blocks have been developed, but are not yet used in production cars. This major unit must be extremely strong and rigid to avoid bending and stretching. It also varies in thickness and does not always cool uniformly to prevent warping by internal stresses of the cylinder bores
