Additional exhaustgas aftertreatment via SCR is not necessary. In terms of maintenance, service life, fuel consumption and weight, the EEV solution for Mercedes-Benz buses is on a par with established BlueTec 5 technology, according to the company. Fuel consumption may also be lower due to reduced exhaustgas backpressure.
This is due to raw, externally premixed fresh charge comprising air, fuel and lube oil being short-circuited into the exhaust during the scavenging process. Even with the move to four-stroke engines, additional complexity will be necessary—possibly exhaust after-treatment—in order to fully meet regulations.
The valve train is operated by low-friction hydraulic roller finger followers and driven by a timing chain with a maintenance-free hydraulic tensioner. Achieving these goals enabled vehicle integration that can tune primary engine orders in the induction and exhaust systems to meet specific vehicle objectives.
If you’re driving down the road and you notice a quiet car in front of you, you should know that the car’s exhaust system is doing its job.
