The development of marine diesel engines in models look relatively stable overall, a few years ago, focused on improving the reliability of models, it is because the development of the supercharger technology, strengthening of diesel marine engine manufacturers to improve quickly, especially oil crisis After reflected in reduced fuel consumption and low-quality fuel oil burning to pursue the goal of a strong economy, national environmental policy limits on diesel emissions increasingly harsh marine engine vendors, and NOx, SO2 and other harmful emissions Increase Positive It is a high-strength and low-quality fuel oil byproducts burning marine engines, marine engines and content price of these types of harmful exhaust gas components, marine diesel engine diesel worse than cars. Each diesel engine manufacturers are committed to following the common pursuit of the new diesel engine. When marine diesel engine when the pressure within the cylinder to near the scavenging pressure (generally scavenging scavenging pressure tank 012, the piston down the scavenging port 3 open (in this case point 4 of the crank position, the scavenging air into the cylinder, at the same time The exhaust gas through the exhaust port in the cylinder expelled cylinder marine engine Weifang |.
