QUOTE: Originally posted by selector Actually, you can compress cold air, and I know this because that is the only way to get diesel-equipped tractors running up in the arctic. The slow crank is more likely a function of crankcase oil viscosity and/or battery condition. Of course, spray ether helps, but if you have enough juice, you just crank the diesel over until the compression warms up the piston top and cylinder head. The fuel is especially formulated for arctic ops, so atomization is not an issue. Once the cylinders get hot enough, they fire. No one said it was pretty, but it works.
