ok.. found it..
". Diesel engines are quality controlled while gasoline engines are quantity controlled. This means a diesel engine runs with an unrestricted airflow and only the injected fuel volume controls the power setting. Diesel engines run lean their whole life without any negative influence.

So yes.
"A diesel has no spark plugs. It has a very high compression ratio--about twice that of a gasoline engine. So the compression stroke builds up tremendous heat and pressure. A readily combustible fuel is injected and the heat of compression instantly ignites it. Unlike a gasoline engine with a throttle plate to regulate airflow, the diesel is unthrottled. It draws in all the air it can, all the time, without wasting energy pulling air past a partly closed throttle. Performance is determined (within combustion limits) by the amount of fuel injected, so the diesel can produce a great deal of torque at low rpm. Step on the accelerator and a variable turbocharger adds still more air, the injectors spray more fuel, and the diesel develops tree-stump-pulling torque before the tach hits two grand. A gasoline engine needs an air-fuel mixture of about 15:1. The diesel can run on mixtures as lean as 100:1."

Thats as close is im gonna get for links. As I said, diesels are not my fortay. Beyond my economic studies and random automotive tech I don't see them often in the US.
