Abstract:
This report is a theoretical study of the potential an ICE (internal combustion engine) has when combined with the load case of a high-performance series hybrid drivetrain. It breaks down the different theoretical variables that affect engine efficiency and possible limitations that arise. The report then moves on to specifying the current emerging technologies associated with increasing engine efficiency such as active, and passive prechamber ignition. The different technologies strengths and weaknesses were then compared with each other to decide the best strategies and technologies to move

Abstract:
The need to minimize carbon dioxide (CO2) emissions is becoming increasingly important with the total number of vehicles throughout the world exceeding one billion. Carbon dioxide emissions can be reduced by improving vehicle fuel efficiency. While electric transportation is gaining popularity, most passenger vehicles are still powered by gasoline or diesel engines. The main objective of this work was to provide opportunities for studying and improving the fuel efficiency of internal combustion engines (ICE). This was achieved by 1) Designing, building and testing auxiliary systems necessary t

Waste Heat Recovery (WHR) could be a good solution to lower the CO2 emission of the Internal Combustion Engine (ICE) without increasing the pollutant emission.

Abstract:
The internal combustion engine has been under considerable pressure during the last few years. The publics growing sensitivity for emissions and resource wastage have led to increasingly stringent legislation. Engine manufacturers need to invest significant monetary funds and engineering resources in order to meet the designated regulations. In recent years, reductions in emissions and fuel consumption could be achieved with advanced engine technologies such as exhaust gas recirculation (EGR), variable geometry turbines (VGT), variable valve trains (VVT), variable compression ratios (VCR) or e

Abstract:
This study has been performed at Powertrain Engineering Sweden AB (PES), a fully owned subsidiary of Volvo Cars Group, which is constantly working to develop and improve internal combustion engines. As part of this work, durability tests are performed to analyse the impact of wear on the engines. At present, there is a strong focus on visual inspections after the engines have undergone durability tests. PES wants to develop a method where collected data from these tests can be used to explain how the phenomenon of knocking and the control of lambda changes over time. The study analyses one spe
