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.original and aftermarket (replacement) Caterpillar intake manifolds

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 aluminum, iron and cast iron. This created certain difficulties. The fact that the collector itself during the engine is very hot and heats the air, which is currently inside it. Air, in turn, expands and enters the cylinders in a smaller volume, resulting in increased fuel consumption and deteriorating the performance of the engine.

As an alternative to metal, since the late 90's, now the last century, many engines use composite materials based on plastic. Due to the low thermal conductivity, such a Caterpillar intake manifold does not heat up so much, as a result, the cylinders are better filled with air, and the engine power is increased per unit of fuel.
