Mercedes-Benz achieved the low emissions solely by means of internal engine measures and without an additional particulate filter in the case of the Mercedes-Benz BlueTec engines or a fuel economy penalty. Additional exhaust gas aftertreatment via SCR is not necessary.
Do they receive HOV access for their improved fuel economy and ultra low emissions? They then combined these estimates with three- and five-year estimates for repairs, maintenance, insurance, fees and taxes from an outside data source. Changes in the exhaust manifolds and turbo from Gen 1 to Gen 2. Are these sales incentivized?
Piston cooling jets, located at the bottom of each cylinder, contribute to fuel economy by squirting oil on the bottom of the pistons to help maintain cylinder temperatures and reduce the possibility of hot spots along the cylinder walls or at the top of the piston that could lead to detonation. liter MultiAir Turbo engine is 9.8:1.
No other diesel sedan offers a better EPA fuel economy highway estimate, Mercedes-Benz notes. Fuel pressure for the BlueTEC direct fuel injection system is 2,000 bar, which makes possible even more power and lower exhaust emissions. When equipped with optional 4MATIC all-wheel drive, its fuel mileage numbers are 42 mpg (5.6
