Why are GE locomotives better than EMD?

Well Silvio, you just gave your self away. Oil Fuel Mixture??????What????? When I take power to the pit, I have never seen them dump in a can of "weed eater 2 cycle blend," in the fuel tank. The EMD 2 cycle diesel operates on the same principle as a detroit diesel. Air is forced into the air box, as the piston reaches BDC, ports in the cylinder are exposed and the air enters the cylinder through them, as the piston heads toward TDC the ports are closed by the piston skirt, fuel is injected and compressed until it ignites, the piston is forced down by this action, as the piston reaches BDC again the ports are exposed and the exhaust valves open. The exhaust gasses are forced out of the cylinder through the ex. valves by the fresh air charge. This whole cycle happens once every revolution of the crankshaft. The air is pressurized in one of two ways. Roots type gear driven blower, or a gear driven/gas driven turbo. The turbo is gear driven until enough exhaust gas volume is produced to drive the turbo, then clutches that drive the turbo are overrun and the exhaust gasses take over. The lube oil is still contained in the cranckcase of the EMD. And GE should have stuck to making toasters! Period. <br />Ken
