Anti-combustion deposit fuel development for 2009 Toyota Formula One racing engine

There are many advantages of the development for the motorsports engines. One example, thanks to high performance, even very small phenomenon such as deterioration of engine performance can be caught. This is a little bit old story, however very interesting how the combustion chamber deposit affects the engine performance deterioration. Toyota participated in Formula One Racing (F1) from 2002 to 2009. As a result of the downturn in the world economy, various engine developments within F1 were restricted in order to reduce the cost of competing in F1. The limit on the maximum number of engines allowed has decreased year by year. Toyota focused on the engine performance deterioration due to the combustion chamber deposits. In 2009, Toyota was successful in reducing around 40% of the deterioration by making combustion chamber cleaner in cooperation with ExxonMobil.
