The primary function of a diesel exhaust system is to remove the spent fuel-air combination from a diesel engine’s combustion chamber through the tailpipe. In recent decades, the government has implemented new rules to reduce emissions from specific components of diesel exhaust gas. Consequently, modern diesel exhaust systems treat emissions and actively help reduce the carbon footprints of diesel-powered cars. Additionally, a diesel exhaust fluid (DEF) may be pumped into the exhaust system to reduce pollutants and improve fuel economy.
A typical diesel exhaust system consists of the following components, each of which serves a distinct function:
Catalytic Converter
Catalytic converters decrease vehicle emissions by converting carbon monoxide to carbon dioxide and hydrocarbons to water and carbon dioxide via chemical processes. Catalytic converters now function at up to 90% efficiency, effectively eliminating diesel odor and soot.
Particulate Filter
A particulate filter, like a catalytic converter, lowers emissions. Particulate filters are intended to capture any residual soot or visible particles that may have passed through the catalytic converter.
Muffler
As is the case with most engines, the muffler’s function is to reduce noise and soundproof the engine. Mufflers decrease noise by reducing vibrations caused by the sound pressure produced by machines.
Moreover, the fuel injection system’s primary function is to supply gasoline to the engine’s cylinders while accurately regulating injection time, fuel atomization, and other characteristics. In addition, Duramax Injectors may help you save money while increasing the performance of your engine. Injection systems are classified into three broad categories: pump-line-nozzle, unit injector, and common rail. These high-performance injectors are designed to assist in the efficient distribution of gasoline, resulting in increased power and efficiency.
You may enhance both atomization and gasoline delivery by upgrading your fuel injector. The simplest injector in a diesel engine is a purely mechanical mechanism. This is the whole inside of a Bosch unit equipped with 12-valve Cummins Injectors. Without the aid of a computer, this injector fires in reaction to the injection pump’s pressure. When the body’s internal pressure reaches a specific point, the check valve opens, allowing gasoline to spray through the nozzle, out the tip, and into the cylinder. Through the injector body, excess fuel is returned to the injection pump.
