The rising complexity of modern automotive engines with an increasing number of actuators and sensors to minimise emissions and fuel consumption and to maximise engine driveability require a detailed supervision for fault detection and on-board diagnosis. The European Community Directive 98/69/EC requires on-board diagnosis for spark ignition engines and will require it for diesel engines as of...

The Acid Deposition Control Title (IV) of the 1990 Clean Air Act Amendments calls for reductions in annual sulfur dioxide and nitrogen oxide emissions in order to “reduce the adverse effects of acid deposition,” without addressing emissions of ammonia. Ammonia is present in precipitation and aerosols as the ammonium cation, NH4. Ammonium is rich in nitrogen and together with nitrate comprises v...

Today, planning and control of logistic processes on automobile terminals are generally executed by centralised logistics systems, which in many cases cannot cope with the high requirements for flexible order processing due to increasing dynamics and complexity. The main business processes on automobile terminals – notification of vehicles by automobile manufacturer, transport to automobile ter...

China’s automobile industry has made great progress and contributed a lot to national economic development, but the problems such as dispersion, small, disorderly, worse" in the industry is still very serious. Starting from the SCP paradigm theory in China’s automobile industry, the article analyses the problems including the market structure, market conduct and market performance in China’s au...

walking being the oldest form of urban transport, and until the advent of major transformationsin transport technology in the nineteenth century, most cities were structured in ways that supported walkability.today, there is a change in transportation which emphasizes, the traditional pedestrian paths which are increasinglybecoming non-regulated spaces when compared to the urban spaces for auto...

In an effort to address climate change, many cities have joined the International Council for Local Environmental Initiatives (ICLEI) whose members commit to work toward five specific program objectives designed to reduce greenhouse gas emissions. This study examines the extent to which 257 member cities in the US have been successful in achieving these program milestones and identifies factors...

This article examines firms’ innovation activities in response to U.S. technology-forcing auto emissions standards enacted between 1970 and 1998. Patent applications in automobile emission control technologies were used as a measure of firms’ innovative responses to regulatory pressures. In addition, we extensively studied secondary literature and industry specific records and conducted targete...

The PressureSense Glow Plug combines a miniature fiber optic-based cylinder pressure sensor with the automotive glow plug. The 1.7mm diameter sensor is sealed inside a glow plug heater and the sensor signal conditioner is encapsulated into a “smart connector”. The sensor operates on the proven principle of light intensity changes, transmitted by two optical fibers, upon reflection from a deflec...

According to the complexity of automobile logistics, we take one company’s automobile logistics as sample to analyze dynamics characteristics of logistic system and to set up system model by applying nonlinear dynamics theory and measure. Also, we can prove that it is applicable to study automobile logistics by this model according to the analysis of the model’s chaotic dynamics characteristics...

two continuously regenerating traps crt-a and crt-b were evaluated under the controlled carbonyl emissions from a turbocharged diesel engine run on an ac electrical dynamometer. the gas-phase carbonyls were taken in silica gel cartridges coated with 2,4-dinitrophenylhydrazine both upstream (baseline) and downstream of the traps, and a total of fourteen carbonyls were identified and then quantif...
