Mercedes diesel

The coupled spectrophone-dilution tube was first used to determine the absorption coefficient of airborne exhaust soot from a 2.4 liter Mercedes Diesel vs. NO2 as a standard (8). The value was found to be (5.5 1.0)m2g 1 at 514.5nm. (The automobile was run on a vehicle dynamometer at a cruise speed of 55 mph, with an average particulate concentration of 0.050 g m 3.)...

The first methanol bus in the world was placed in revenue service in Auckland, New Zealand in June 1981. It was a Mercedes O 305 city bus using the M 407 hGO methanol engine. This vehicle operated in revenue service for several years with mixed results. Fuel economy on an equivalent energy basis ranged from 6 to 17% mote than diesel fuel economy. Power and torque matched the diesel engine and drivers could not detect a difference. ReHabiUty and durabihty of components was a problem. Additional demonstrations took place in Berlin, Germany and in Pretoria, South Africa, both in 1982. 

Some of these tmcks were said to have been manufactured by the firm of Saurer. The ironic part of this tale is that even before the war, Saurer was arguably the manufacturer of the world s best and most efficient producer gas trucks. During the war, this Swiss-Austrian firm continued its technical leadership over Mercedes, Opel, and Ford who were actually manufacturing far more producer gas vehicles.58 More than 6,000 Saurer trucks were built in Vienna during the war and most, if not all, had producer gas generators and Diesel engines. How absurd to believe anyone with even a minimum of technical understanding would even try to use the exhaust from these trucks for murder, when the fuel itself was a thousand times more lethal ...
