Now its been little freeze, -1 to -4 celcius.
If i start without preheater, it starts just "showing" key but runs about second little bit rough.
This is my first DI diesel so how it should be starting at cold?
I have piezo plug with diesel injection at intake manifold and i tested earlier that it works.
Im not so worry about that second roughness but when there is -10 or -20 will it be super rough? I usually use preheater at winter but you will never no if you had to cold start it.
