Driven by pollutant emissions stringent regulations, engines manufacturers tend to reduce the number of injectors and rely on lean combustion which impacts the light-around phase of ignition.
The Mercedes motorsport chief, Toto Wolff, has warned of the serious financial consequences if regulations on engine power units are opened up.
The agreement (which also imposed some regulations on engine noise) does not expire until 2015, but a number of public officials, among them Mr. Rosendahl, Assemblyman Ted W.

In May 2005, an IMO regulation on engine emission standards for NOx came into force for engines above 130 kilowatts, in the form of Annex VI of the International Convention for the Prevention of Pollution from Ships.
"We think there is a very strong argument that, in the new regulation, search engines should not be classed as data controllers, and therefore not liable as 'owners' of the information they are linking to.
He had built the Falcon IndyCar in 2002 in Charlotte, North Carolina (the car never raced because of a sudden change in the I.R.L./IndyCar engine regulations) and he was now working as an engineer at Haas/C.N.C. Racing, a Nascar team financed by Gene Haas.
The promulgation of these increasingly stringent regulations has required engine manufacturers to make dramatic changes in the combustion characteristics of new engines and introduce new pollution control measures, such as fuel reformulation, diesel particulate filters (DPFs), and oxidation catalysts (Tschoeke et al., 2010).
It could see new engine regulations by 2011 which could see the introduction of bio-fuels.
