Information:
There are two inlet valves and one exhaust valve for each cylinder. Inlet valves open when the piston moves down on the inlet stroke. When the inlet valves open, cooled compressed air from the inlet port is pulled into the cylinder. The inlet valves close and the piston begins to move up on the compression stroke. The air in the cylinder is compressed. When the piston is near the top of the compression stroke, fuel is injected into the cylinder. The fuel mixes with the air and combustion starts. During the power stroke, the combustion force pushes the piston downward. After the power stroke is complete, the piston moves upward. This upward movement is the exhaust stroke. During the exhaust stroke, the exhaust valve opens, and the exhaust gases are pushed through the exhaust port into the exhaust manifold. After the piston completes the exhaust stroke, the exhaust valve closes and the cycle starts again. The complete cycle consists of four stages:
Inlet stroke
Compression stroke
Power stroke
Exhaust strokeExhaust gases from the exhaust manifold enter the turbine side of turbocharger in order to turn the turbine wheel. The turbine wheel is connected to a shaft which drives the compressor wheel. Exhaust gases from the turbocharger pass through the exhaust outlet pipe, the muffler and the exhaust stack.The CGI system sends hot exhaust gas from the DPF to the CGI cooler. The hot exhaust gas is cooled in the CGI cooler. The now cooled exhaust gas passes through an electronic controlled flapper valve. The electronically controlled flapper valve is hydraulically actuated. The engine is using air from the truck's air filter system when the flapper valve is in the full OFF position. As the flapper valve starts to open the flow of cooled exhaust gas from the CGI cooler mixes with the air flow from the air filter. As the demand for more cooled exhaust gas increases the flapper valve opens wider. This increases the flow of cooled exhaust gas from the CGI cooler. As the demand for more cooled exhaust gas increases, the demand for air flow from the engine's air filter decreases.Turbocharger
