An Airgas compression ignition (AGC) cylinder is a type of spark-ignition engine cylinder that uses a high-pressure air supply to ignite the fuel in the cylinder. The high-pressure air supply, which comes from AGC hydraulic cylinders, is known as compressed air or supercharger air. In other words, it’s additional air used for compression rather than combustion.
A standard spark-ignition engine has two main combustion chambers: the intake and exhaust. The individual spark plugs position themselves in these combustion chambers to ignite the fuel at specific times, producing fire that drives the piston up through a mechanical pump to create power on demand.
AGC cylinders have more than one combustion chamber — each with its own set of spark plugs. The second chamber is called an expansion chamber and its purpose is to increase volume by using more efficient venturi technology to pressure out low-entropy gas before ignition and burn it more completely. Its expanded volume can be achieved by adding extra pistons or cylinders — a process known as supercharging/AGCing (sometimes called volumizing).
What are the benefits of using AGC?
There are a few advantages to using AGC hydraulic cylinders: No more expensive spark plugs. The cost of spark plugs has gone up over the years and they are the single most expensive component on an engine. Besides, they wear out quickly, pollute the air, and make engines hard to start. AGC hydraulic cylinders use high-pressure air to ignite the fuel and keep it burning for longer periods of time. This means engines using this technology last longer without needing to be overhauled as often. Increased power and torque.
The ability of an engine to produce power is directly related to the amount of air available to burn the fuel. In a conventional engine, this is determined by the number of spark plugs per cylinder. In an engine using AGC cylinders, this is determined by the amount of air entering the cylinder. Using more air means there is more power and torque. Increased fuel economy. The ability of an engine to get the most out of fuel is directly related to its efficiency.
An efficiency of 70% or higher is considered very good. An engine that gets only 50% of the possible power out of the fuel is not only inefficient but also underpowered. Improved engine life. Engines have a limited life after they have been manufactured. Overhauling an engine to replace spark plugs or install a new engine because it dies after a certain age is expensive and time-consuming.
Build of an AGC cylinder?
AGC hydraulic cylinders are spark-ignition engine cylinder that uses supercharger air to power the combustion engine. The supercharger, which is usually a turbocharger, is positioned behind the engine to increase airflow and improve torque and engine economy. An AGC cylinder is a two- or three-barrel engine that uses two, three, or four high-pressure gas generators/compressors to provide additional air volume. AGC hydraulic cylinders or engines are sometimes referred to as boost-equipped engines.
How does an AGC cylinder work?
AGC hydraulic cylinders work like this: A standard spark-ignition engine has two main combustion chambers: the intake and exhaust.
