Caterpillar engine parts

Caterpillar crankshaft is one of the most responsible and costly design elements of an internal combustion engine. It converts the reciprocating motion of the pistons into a torque. The crankshaft senses periodic load variables from the pressure forces of the gases, as well as the inertia forces of the moving and rotating masses.  The crankshaft of the engine, as a rule, is a one-piece structural element.  The shaft is made of steel by forging or cast iron. On diesel and turbocharged engines, more robust steel crankshafts are installed. The connecting rod, located between the two cheeks, is called the knee. The knees are located depending on the number, location and order of operation of the cylinders, engine speed. The position of the knees should ensure the stability of the engine, uniformity of ignition, minimum torsional vibrations and bending moments.  The rotation of the crankshaft in the supports, and the connecting rods i →

Caterpillar camshaft in the gas distribution system provides the main function - the timely opening and closing of the valves, thereby bringing in fresh air and exhaust gases. In general, the camshaft controls the gas exchange process in the engine. To reduce inertia loads, increase the stiffness of the elements of the gas distributing mechanism, the camshaft must be located as close to the valves as possible. Therefore, the standard position of the camshaft on a modern engine in the cylinder head. The basis of the design of the camshaft are cams. For each valve, as a rule, one cam is used. The cam has a complex shape that allows the valve to open and close at the set time, and raise it to a certain height. Depending on the design of the gas distribution mechanism, the cam interacts with either the pusher or the rocker. From the longitudinal movement of the camshaft, the thrust bearings, located near the drive gear (sprocket), are held.The camshaft is  →

Caterpillar piston rings form a tight connection of the piston with the walls of the cylinder. They are made of modified cast iron. Piston rings are the main source of friction in the internal combustion engine. The frictional losses in the rings reach up to 25% of all mechanical losses in the engine. The number and location of the rings depends on the type and purpose of the engine. The most common scheme - two compression and one oil ring. Caterpillar compression rings prevent the breakdown of gases from the combustion chamber into the crankcase of the engine. The first compression ring works in the most difficult conditions. Therefore, on the pistons of diesel in the ring groove a steel insert is installed, which increases the strength and allows to realize the maximum compression ratio. Caterpillar compression rings can have a trapezoidal, barrel-shaped, conical shape, some performed with a cutout.   →

Caterpillar piston is the most characteristic part of the internal combustion engine, since it is with its help that the thermodynamic process of the engine is realized. The conditions in which the piston works are extreme and characterized by high pressure, temperature and inertial loads. Therefore, the pistons on modern engines are made of light, durable and heat-resistant material - aluminum alloy, less often of steel. Caterpillar pistons are manufactured in two ways - injection molding or stamping, there are also forged pistons, but this method of production is used very rarely these days. The Caterpillar piston is a one-piece unit that is conditionally divided into a head (in some sources it is called the bottom) and a skirt. The shape and design of the piston is largely determined by the type of engine, the shape of the combustion chamber and the combustion process flowing in it. In the head of the piston of a diesel engine, a combust →

The Caterpillar engine flywheels directly to several systems and performs the following functions: Reducing the unevenness of the crankshaft rotation; Transmission of torque from the engine to the gearbox; Transmission of torque from the starter to the Caterpillar engine crankshaft. Smoothing of torque pulsations due to periodic accumulation and feedback by the flywheel kinetic energy. Energy is stored during the working stroke of the piston and is consumed at other strokes, including the removal of Caterpillar pistons from dead points. The more cylinders in the engine, the more time the working stroke of the piston takes, then, the torque of such an engine is more even, and the mass of the flywheel can be reduced. The flywheel is attached to the end of the crankshaft near the rear main bearing. This is usually the most powerful bearing in the engine, since it must withstand the weight of the flywheel and the loads associated with its operation. All necessary Caterpilla →

The Caterpillar engine repair kit is a set of seals necessary to repair the engine. The repair kit includes the following elements: 1. Cylinder head gasket. 2. Valve cover gasket. 3. Rings of wells of glow plugs. 4. Valve nuts for securing the valve cover. 5. Intake and exhaust manifold gaskets. 6. Throttle valve installation gasket. 7. A lining of the valve of idling. 8. Nozzle gaskets. 9. Oil-removing rings. 10. Seals: a camshaft, a cranked shaft (forward and back), the oil pump. 11. Oil pump Gaskets. 12. Turbocharger gasket. 13. Oil sump gasket. It should also be understood that for Caterpillar equipment it is justified to use both original Caterpillar engine repair kits and aftermarket (replacement or duplicate) Caterpillar engine repair kits.
