The twin - scroll technology provides for a more spontaneous build - up of charge pressure, making effective use of exhaust gas back pressure, exhaust gas temperature and exhaust gas impulse. (ausmotive.com)
The study also runs simulations for just natural temperature influences (Figure 3), and just greenhouse gas temperature influences (Figure 4). (skepticalscience.com)
A single combustion cycle is sufficient for the exhaust gas temperature to rise. (mazda.com)
