Study on the Design of Motorcycle Muffler with Catalyst for Exhaust Gas Purifying
As the increase of motorcycle quantity and production, the pollution of motorcycle emission and noise has attracted more and more attention from the society. Meanwhile the Emission and Noise Control Standard get much stricter, especially in order to meet the requirement of the newest Emission III , catalyst has been the standard choice for the [...]
Improvement of Combustion and Emission of Natural Gas Engine Based on Double Dilution
The energy deficient and global environmental problem has become the focus which the world pays attention. Along with the technological advance and development of society, quantity of automobile which has taken the massive limited oil resources increases year by year. It has enlarged to the atmospheric pollution level simultaneously. Natural gas engines commended considerable respect, [...]
Analysis of Performance and Regeneration Process on the Diesel Particulate Filter
From proposeing the principle of diesel engine to the current one hundred years,thediesel engine technology is developed comprehensively,as its good performance in power,economy and reliability,diesel engine is widely used in a variety of mechanical devices,especially as a vehicle power.Compared with the gasoline engine, HC and CO of dieselengine emissions is very low, NOx emissions in [...]
Effect of Ignition Timing and Injection Timing on Performance of Natural Gas Engine
As the energy shortage and environment pollution become more and more stringent, the clean alternative fuel vehicles play an important role in the automobile industry. Among them, the natural gas becomes the preferred choice due to its abundant resources, clean combustion and low CO2 emission level. However, it features higher ignition temperature, lower flame propagation [...]
Elementary Study of Gasoline Engine Start-Stop Technology in Motor Drive Mode
Because of the energy crisis and environmental pollution are becoming more serious, more and more governments are beginning to carry out many more strict emissions regulations, and also to promote the engine R&D of new technologies and applications, in order to mitigate the stress of motor vehicles for energy and the environment. So in the [...]
Research on the Fuel Supply System and the DME∕Diesel Blending Performance of Diesel Engine
Environment and energy problems have become global crisis. As a pollution source, vehicle has been badly influencing environment, threatening people’s health condition and destroying ecological balance. Meanwhile, it is one of petroleum consuming sources. How to control the emission from the root is still a hard task, although the existing inboard purifying measures and after [...]
Experimental Research on the Knocking Phenomenon in HCCI Combustion and Its Control Strategy
Homogeneous charge compression ignition (HCCI) is a combustion process with high efficiency and low emission. But compared to traditional gasoline engine, limited by knocking, HCCI engines have much reduced operation range. The maximum IMEP achievable under naturally aspirated HCCI operation was about 0.5MPa. In this paper, HCCI knock phenomenon and its control strategy were investigated [...]
Research on Speciation and Emissons of Mercury、 Chlorine、Fluorine During Coal Utilization
Mercury、fluorin、chlorine emissions from coal utilization have already caused serious damage to environment and human health.Therefore, carring out the research of Hg、F、Cl and find effectively control methods are both important to minimize their emissions.The research is based on mercury、chlorine and fluorine during coal pyrolysis, gasification and combustion. A-bench-scale experiment was designed to investigate the migration and [...]
Numerical Simulation of Biodiesel Spray and Applied Research
The high demands for energy together with the non-renewable of the fossil fuel reserves have result in exploration of alternate energy sources. Now more and more people focus on biodiesel because it is renewable, non-toxic, biodegradable etc. So biodiesel is a perfect alternative fuel for diesel engine in the future.The combustion process in diesel engine [...]
