Improvement Trends for Internal Combustion Engines

Internal combustion engines have remained a challenge due to depending heavily on fossil fuels, which are already limited reserves, and a requirement for improvement in emission levels continuously. The number of advanced technologies such as hybrid systems and low-temperature combustion engines has been introduced, and a number of reports about the use of alternative fuels […]
