Mercedes Gas Turbine
Mercedes would like to continue making big cars. Engineers there think that maybe they can by using a gas-turbine engine to acceptable mileage. They calculate that the prototype car in it will go, and on which they are already working, will weigh 3,350 pounds when finished. By comparison a Toyota Starlet weighs 1,730 pounds.
Recently I was admitted inside the Mercedes-Benz experimental design offices and research laboratories to look at work in process. I was accompanied by Dr. Michael Wessels, one of the engineers who works full time on the gas turbine project. Dr. Wessels spread a blueprint on a big table and explained the advantages of the gas-turbine engine:
Multi-fuel capability.
Low emission levels due to continuous combustion with a high proportion of excess air.
Simplified maintenance no oil changes are needed.
Minimal internal friction low wear rates result in long engine-life expectancy.
No vibration because there is no reciprocating motion as there is in a conventional piston engine.
Low noise level which makes silencing easy.
Mercedes is looking at the year 2000 as a possible production date. However, before turbine-powered Mercedes start rolling off the production lines, many problems must be overcome.

A turbines aerodynamic efficiency is dependent on the peripheral speed of the turbine rotors. To maintain the necessary speed, a small automotive-type turbine has to spin faster. This can cause temperatures and increased revolutions per minute (rpm).
Clearances are a problem. When scaling down a turbine to automotive size, tolerances which are already minimal cant be scaled down proportionally. So the smaller unit tends to operate with disproportional large clearances and loses aerodynamic efficiency.
But the biggest problem of all is temperature, says Dr. Hans Joachim Forster, director of research for Mercedes-Benz. At 2,400 degrees F the gas turbine reaches the same overall efficiency as a good diesel engine under full load, and exceeds the part-load efficiency of a modern Otto-cycle piston engine, he says.
Only ceramics can withstand these temperatures. Most promising are silicon nitride and silicon carbide.
