What will I learn?
Diesel particulates and NOx emissions are major current problem areas in diesel engine development with ever more stringent emissions legislation to meet in the automotive, industrial, marine and power generation markets. On this course you’ll concentrate on the engine technology for low emissions, their fuel requirements and after-treatment techniques. The course does not cover the details of the particulate measurement and analysis techniques, which are fully covered in the companion short course on Engine Emissions Measurement. It does, however, cover particle size analysis and particle number measurement, plus measurement emission for PM for Euro 6 and beyond.
How will I benefit?
The course consists of review lectures by Professor Andrews of the latest published information on engine design for low emissions, on the influence of fuel and additive composition on emissions and on the influence of lubricating oil on emissions. These review lectures are updated each year and incorporate the latest published results from engine manufacturers, consultants and oil companies as well as universities. A range of presentations is also given by industrial companies on their recent low emission engine research into diesel particulates and NOx reduction techniques as well as on their views on engine technology requirements for future emissions legislation.

Who should attend?
Who should attend?
The course is relevant to vehicle manufacturers, engine consultancies and emissions control R&D with an interest in RDE and engine and emissions control technology for Euro 6 and beyond as well as for technology for future CO2 emissions reduction. The course is also relevant to those who need to understand real world traffic emissions from an air quality viewpoint and to those involved in emissions regulation formulation and enforcement.
