Purpose: Engine converts energy into torque.
Major Role: The engine requires energy which it gets from fuel. It converts the fuel into mechanical work or torque. This torque is applied to the wheels to make the car move. The engine has cylinders with pistons that move up and down. These pistons are powered by controlled explosions, igniting the fuel. This is called combustion.
Part description: Engines of vehicles are designed around sealed metal cylinders. Modern vehicles have four, six or eight cylinders. Some also have up to sixteen. Family cars a decade ago had a 2.0-litre petrol engine. Now turbo-charged engines are 1.0 liters. Engine size is expressed in liters. One liter measure 1,000cc (cubic centimeters). While bigger engines produce more power, smaller ones are equally powerful. Majority of the BMW cars on sale are powered by four-cylinders while Chrysler engine are V6. The power of the engine is measured in horsepower. This is an important specification and shows the engine performance. An engine with more horsepower and torque will accelerate quickly, while an engine with lesser horsepower will offer fuel economy instead of high-speed luxury drive. The mechanism of a cylinder is simple. It has pistons designed to move up and down and ignite the fuel with a spark for internal combustion and release the exhaust gases. Engine components are many and here is a list of some of the major components.
Engine block: A core engine part is made of aluminum or iron with several holes and contains cylinders, provides a path for water and oil flow to lubricate and cool the engine. The blocks, both big block and small block, has pistons, crankshaft, camshaft and depending on the vehicle.
Piston: Cylindrical apparatus with a flat top surface. It transfers energy that is created from burning to the crankshaft to move the vehicle. Pistons move up and down within the cylinder for each rotation of the crankshaft. Cast or forged from aluminum alloys, crosshead pistons are for large slow-speed diesel engines and slipper pistons which are smaller in size, for petrol engines. Pistons will move up and down 2500 times per minute on an engine that rotates at 1250RPM. Rings lie inside the piston that help compression and reduce fiction by rubbing on the cylinder.
The crankshaft: Placed on the lower section of the engine block, within the crankshaft journals (shaft area that rests on bearings), the up and down motion of the crankshaft support the motion of the piston corresponding with the engine speed. There are two different measurements you will need to know regarding the crankshaft. (see Used Crankshaft for more information)
Camshaft: In many modern vehicles, they are located on the cylinder heads called dual overhead Camshaft (DOHC)or Single Overhead Camshaft (SOCH). They are supported by lubrication immersed high longevity series of bearings. The camshaft regulates the opening and closing of the valve, takes rotatory motion from the crankshaft, shifts to up and down movement, and controls the progress of the lifter, pushrods, rockers and valves. (see Used Camshaft for more information)
Cylinder heads: These are attached to the engines through cylinder bolts and sealed with gasket heads. This component contains valve springs, valves, lifters, pushrods, rockers, and camshafts. They are key to controlling air flow in and out of the cylinders and fuel deployment. Cylinder heads are available in aluminum and iron casting. Port heads can be rectangular or cathedral. Lightweight titanium valves are the standard equipment and are used in high-speed engines. A broad range of cylinder heads is available with us. (see Used Cylinder heads for more information)
Timing Belt /Chain: They synchronize the movement of the camshaft and crankshafts ensuring that the engine runs efficiently. The timing belt is a toothed belt while the chain is a roller chain. There are several tooth profiles 3mm, 5mm, 8mm and 14mm. To determine the exact pitch and tooth profile measure the width and overall length of the timing belt. You can count the teeth and the cogs and multiply with the pitch to get the length you desire. Common materials used are neoprene and polyurethane.Fast Shipping

That depends on the condition of your engine. Complex engine repairs can be challenging and often lead to more complications. The cost can exceed your estimation. However, if the problem is basic, then repairing is a better idea. Engine troubleshooting begins on a lighter note and then turn massive. So, consult with your technician and fix your engine. If you do not have the budget for a company manufactured engine, then buying a used engine is a sensible idea. Used engines, if bought from a reliable source, will last for years without complaints. You can enjoy a smooth drive at less than half the price of the original engine.What is a used engine?
Used engines are taken from another vehicle that may have been out of use for various reasons. Vehicles with relatively low mileage that might have suffered wreckage, are not roadworthy. Their engines are directly taken from the vehicle and tested thoroughly to check their increased usability.What is a fully assembled used engine?
A fully built used engine includes forged pistons and connecting rods, the ductile iron cylinders that can sustain high pressure, the valvetrains that can easily bear surmounting engine speed, the hardware that has the right buildup to hold everything together with well-lubricated machinery.What are OEM Engines?
OEM or Original Equipment Manufacturer engines are made by engine manufacturers and not third-party manufacturers. These are the exact replacement for the original engine. They have a one process engine software selection which makes the replacement of the engine hassle-free. They are supported with a warranty. However, they are much more expensive than used engines. Big Mouth Direct has access to the proper used OEM engine that the car manufacturer installed in the vehicle when it was manufactured. We can provide certified (original equipment manufacturer) OEM used engines at a much lesser price.Are you searching for Transmission?
