A modern TDI using a piezoelectric injector may have up to as much as five injections per power stroke as far as I've read.
Given a four stroke, four cylinder TDI engine using injectors of that type, is it reasonable to assume that the engine may in total perform 100 diesel injections per second at 1,200 rpm?
1,200 rpm = 20 revolutions per second.
As the engine has 4 cylinders, it has a power stroke occurring on every crankshaft rotation, implying 20 power strokes per second.
With up to 5 injections (including pilot injection, main, post, etc), is it reasonable to assume a modern TDI can in total perform up to 100 diesel injections per second of operation at 1,200 rpm?
The engine in question has a total of four cylinders. So while we know that a typical four stroke engine (1 cyl) will fire every other rotation of crankshaft, the engine discussed will fire every half rotation as a whole. Please correct me if I'm wrong
