Caterpillar inlet and exhaust systems

Caterpillar inlet and exhaust systems

The inlet system Caterpillar is designed to allow the engine the required amount of air and the formation of a fuel-air mixture. The term "intake system" has appeared with the development of the design of internal combustion engines, especially with the advent of a direct fuel injection system. The equipment for supplying the engine with air ceased to be just an air duct, but turned into a separate system.

Caterpillar inlet and exhaust system partsTo improve the filling of the cylinders with air, the Caterpillar turbocharger is used to increase the power in the design of the modern diesel injection system.

The design of the intake system includes an air intake, a Caterpillar air filter, a throttle, an intake manifold. For individual engine designs, intake valves are used. Tubes connect all elements of the intake system.

Air intake provides air intake from the atmosphere and is a branch pipe of a certain shape.

The Caterpillar air filter serves to purify air from mechanical particles. The filter element is made of special paper and placed in a separate housing. The filter element of the air filter Caterpillar is an expendable material, that is has a limited service life. Depending on the operating conditions of the Caterpillar equipment, the life of the filter element may vary.

The intake manifold distributes the airflow through the cylinders of the engine and gives the air the necessary discharge. The discharge that occurs in the intake manifold is used in the fuel injection system.

How the Caterpillar Intake System Works

The operation of the intake system is based on the difference in pressure in the engine cylinder and the atmosphere occurring at the intake stroke. The volume of incoming air is proportional to the volume of the cylinder. The amount of incoming air is regulated by the position of the throttle Caterpillar valve, depending on the mode of operation of the engine.

The Caterpillar exhaust system is designed to remove exhaust gases from the Caterpillar engine cylinders, to cool them, and to reduce noise and toxicity.

The exhaust system includes a number of structural components, including the exhaust Caterpillar manifold, particulate filter, silencer and connecting pipes.

All the components of the exhaust system are located underneath the Caterpillar Construction equipment.

Caterpillar turbochargers
Caterpillar turbocharger is a technically sophisticated mechanism that uses the kinetic energy of the exhaust gases to increase the pressure inside the Caterpillar intake system. Compressing, a mixture of fuel and air increases the mass of the fuel charge inside the Caterpillar cylinders, which increases the caloric content and, consequently, the engine power. The essence of the Caterpillar turbocharger is the strongest compression of air that enters the engine and enriches the fuel mixture, creating a high explosion power in the cylinder - this greatly improves the mass ratio of the Caterpillar engine to its power. Based on this, it can be argued that an engine with a Caterpillar turbocharger produces much more useful energy than the same unit without it. The operating speed of the Caterpillar turbine can be about 250,000 - 280,000 rpm. For comparison, the speed of the internal combustion engine itself is 30 times less. And since the Caterpillar turbocharger works by exhaust gases, 
Caterpillar intake manifolds
Air or fuel / air mixture enters the cylinders through the Caterpillar intake manifold. The main purpose of the intake manifold is to ensure an even distribution of air or working mixture between the cylinders. This directly affects the efficiency of the Caterpillar engine. In addition, other nodes can be attached to the manifold. The principle of operation of the intake manifold of the Caterpillar engine is quite simple: air or its mixture with fuel, getting inside through the inlet, is divided into several streams, according to the number of cylinders of the engine. Pistons, moving downwards, create a vacuum in the collector, which can reach large values. This partial vacuum is also used to neutralize crankcase gases. They pass through the engine crankcase ventilation system into the Caterpillar intake manifold, mix with the fuel-air mixture or air and are burned in the cylinders. Until recently, the main material for the manufacture of the Caterpillar intake manifold of was al 
Caterpillar air filters
Caterpillar air filter for the engine - a paper, felt or other air cleaner that prevents dust and dirt particles from entering the fuel / air mixture system. Just like the Caterpillar oil and fuel filter, the air contributes to a stable and trouble-free operation of the internal combustion engine. The purpose of the air filter For the smooth operation of the Caterpillar engine, as you know, you need air. If it contains mechanical impurities or dust particles, the functionality of the motor is impaired. The air filter serves as a reliable barrier to various kinds of contaminants. Replacing the Caterpillar air filter - a responsible process, to ignore which is unacceptable. Moreover, it needs to be done in a timely and regular manner. For Caterpillar heavy equipment, the filter change becomes especially urgent. The reason for this is the work of the Caterpillar heavy equipment in difficult conditions, such as quarries, mines, construction sites and so on, far from service organizat
