What does an aftercooler do on a diesel engine?
What Is an Aftercooler on a Diesel Engine? An aftercooler is a device positioned on a marine engine that controls the temperature of the air after it has traveled through the engine’s turbocharger. The turbocharger increases a boat’s power and energy efficiency by pushing pressurized air into the cylinders.
What is after cooler in engine?
– An aftercooler is a heat exchanger used in turbocharged engines (after the compressor) to cool the compressed air off back to near ambient temperature as soon as it is discharged from the compressor. An intercooler is a mechanical device used commonly on turbocharged and supercharged engines for intake air cooling.
What is after cooling?
An aftercooler is a mechanical cooling unit that operates on the principles of heat exchange between two mediums usually water and air. Aftercooler units can be used to attain temperatures between 5-20°F immediately after compressed air is released from the compression unit.
What is a aftercooler used for?
What is an aftercooler? An aftercooler is a heat exchanger that cools the hot compressed air to precipitate the water that otherwise would condensate in the pipe system. It is water-cooled or air-cooled, is generally equipped with a water separator with automatic drainage and should be placed close to the compressor.
What is turbo charged after cooled?
The term aftercooler refers to the charge air being cooled after being compressed in the compressor. Increasing demand for improvements in fuel economy and exhaust emissions has made the charge air cooler an important component of most modern turbocharged engines.
What are the three types of aftercooler?
Types Of Aftercoolers. The two most common types of aftercoolers are air-cooled and water-cooled. Air-cooled aftercoolers use ambient air to cool the hot compressed air.
Are all intercoolers the same?
Your truck’s charge air cooler (or intercooler) is responsible for keeping the air going into your engine nice and cool, promoting engine efficiency and fuel economy. When searching for a charge air cooler, it’s important to know that not all intercoolers are built the same.
What is delay period in CI engines?
Abstract The ignition delay in a diesel engine is defined as the time interval between the start of injection and the start of combustion. This delay period consists of (a) physical delay, wherein atomisation, vaporization and mixing of air fuel occur and (b) of chemical delay attributed to pre-combustion reactions.
Where is the aftercooler located?
The aftercooler should be located as close as possible to the discharge of the compressor. There are two basic types of air aftercoolers: air-cooled. water-cooled.
What is a compressor aftercooler?
An aftercooler is a mechanical heat exhanger that is designed to remove the heat-of-compression from the compressed air flow and to prep the air so it can then enter a dryer and/or be used in air-operated equipment.
Why do you need an aftercooler on a diesel engine?
This device can manage air temperature on diesel engines for boats. What many operators fail to realize about aftercoolers is that they can fill up with condensation under humid conditions. Believe it or not, this is fairly normal and more harmless than you may think. What Is an Aftercooler on a Diesel Engine?
What is the cooling process of a diesel engine called?
The process of cooling the turbocharger delivery of an engine is called charge cooling and the cooler is known as aftercooler. To study and analyze the effect of after cooling in a turbocharged diesel engine an aftercooler was designed, fabricated and installed with a turbocharged marine diesel engine.
What causes condensation in a diesel engine aftercooler?
Marine diesel engine aftercooler condensation is common, especially in warm weather. When hot, humid air blows through the aftercooler, it can cause water droplets to form and settle at the bottom of the device. While some operators might see this as an issue, it’s usually pretty minor.
Which is the last cooling stage before the engine?
However, with further developments in forced air intake systems, the formal meaning of “intercooler” has changed to mean a cooling stage interposed between successive “heating” stages, such as in an engine with series connected turbochargers. An “Aftercooler” is therefore the last cooling stage before the engine.
