ECI’s own EPA Cowl design was utilised to mitigate water ingress into the exhaust flue giving the exhaust system longer life. Seal rings are arranged at both ends of the rotor part of the supercharger. When the air filter resistance exceeds the following values, the air filter element shall be replaced. For a well burned diesel generator set, the smoke from the exhaust pipe is colorless or light gray. Please install heat insulation measures on the surface of the external exhaust pipe. If the return tube of the supercharger is blocked or damaged, the oil pressure in the middle shell will rise and the oil will flow along the seal to the compressor or turbine inlet vortex shell. design of an engine room ventilation system. One fan pushing the air into the room and being mounted in the wall opposite the generator end of the set. The exhaust manifold and turbo charger must not be lagged, only the exhaust pipe silencer. B. Expansion joints are not allowed to eliminate misalignment between tubes. Exhaust gas, however, contains components that are harmful to human health and/or the environment. A. Injector nozzle spray poor atomization or dripping oil. Engine Exhaust Considerations The exhaust system of a generator has several inherent design problems that must be considered. The inner diameter of the intake pipe should not be less than 200mm, and the inner wall of the pipe should be smooth without soldering slag particles. These characteristics impose severe limitations on what can be done to silence the engine exhaust noise: nVery High Noise (100 to 120 dBA @ 1 m) nHigh Temperatures (950 to 1050 ο F) nHigh Velocities (5,000 to 15,000 fpm) The exhaust system may require a Department of Natural Resources (DNR) study for the effects of exhaust dispersion using computational fluid dynamics, and engineers should be aware of where exhaust fumes may go (see Wisconsin DNR example). Due to the high surface temperature of the exhaust pipe when the diesel generator set works, the installation of the exhaust pipe should avoid approaching the flammable object. Noise. The reason is that the piston ring is stuck in the ring groove, the piston ring has insufficient elastic force or the openings overlap, the clearance between the piston and the cylinder is too large, or the chamfer ring is incorrectly installed. Diesel generator oil supplies the supercharger with bearings and provides some cooling with its working oil pressure through the tubing. The oil will pass through the compressor seal ring and blow into the cylinder of the diesel engine with the pressurized air. As a consequence, emission levels of these exhaust gas components became regulated.
