Book Description
Diesel engine performance during cold starting is very crucial for smooth engine start at undesirable emission level. The development of cold start strategies that improve combustion stability relies mainly on the understanding of the combustion process during the cold starting. Even for modern diesel engines, the conditions during the cold start is far from normal operation characterized by large amount of unburned hydrocarbon emissions and long start to idling time. Thus, the use of an in-cylinder combustion sensor to measure the combustion quality during engine starting can significantly improve engine cold start control strategies. The ion current sensor has the potential to be used as onboard sensor to measure the combustion process during engine operation and can be used as feedback to the engine control unit. The aim of this research is to study and determine the combustion instability and its impact on various combustion and ionization characteristics by performing cycle analysis for a comparison between engine performance using ultra low sulfur diesel (ULSD) and aviation jet propulsion (JP8) fuels during cold start at 25 degrees Celsius. It also shows a comparison between two ion current sensors during low load idling using the same fuels. For this purpose, the glow plug and fuel injector of VW 2.0L turbocharged diesel engine were modified and electrically insulated to be used as ion current sensors. The experimental test was conducted to study the combustion process and emission product produced during low load idling.

Book Description
The start-up process constitutes one of the most important states of vehicle internal combustion engine operation. It enables the internal combustion engine to run autonomously in neutral gear. Increased emission of toxic components of exhaust gases, significant wear intensity of friction pairs of the engine, and occurrence of sudden overloads in the vehicle electrical start-up system can be observed during the start-up process. The Vehicle Diesel Engine Start-up Process: Operational and Environmental Aspects offers insight into the start-up process of a vehicle's diesel engine and is the result of the author’s academic research carried out for more than 25 years. The book discusses the impact of road transport on the natural environment of humans, with special attention to toxic emissions from diesel engines in particular. The multi-stage start-up process of an internal combustion engine is analyzed in terms of actual operation of vehicles in a selected transport system. Attention is also paid to the main factors that influence the start-up parameters of a diesel engine. The book is aimed at professionals and academics in mechanical engineering with an interest in environmental and operational aspects of internal combustion engines.

Book Description
Homogeneous charge compression ignition (HCCI)/controlled auto-ignition (CAI) has emerged as one of the most promising engine technologies with the potential to combine fuel efficiency and improved emissions performance, offering reduced nitrous oxides and particulate matter alongside efficiency comparable with modern diesel engines. Despite the considerable advantages, its operational range is rather limited and controlling the combustion (timing of ignition and rate of energy release) is still an area of on-going research. Commercial applications are, however, close to reality. HCCI a.
