What is diesel injection timing?
Start of injection (SOI) or injection timing is the time at which injection of fuel into the combustion chamber begins. It is usually expressed in crank angle degrees (CAD) relative to TDC of the compression stroke.
What is the advantage of indirect injection ( IDI )?
The indirect injection (IDI) system in older engines injected fuel into a pre-combustion chamber which then fed the main combustion chamber. What is the advantage of CRDi? CRDi ensures the fuel injection timing, quantity of fuel and atomisation or fuel spray are controlled electronically using a programmable control module.
How does the electronic fuel injection system work?
The current from the ignition coil jumps the small air gap between the rotor and the posts, sending high voltage through spark plug wires, to each cylinder’s spark plug at a specific time. Note that these systems needed a way to alter timing. At high engine speeds, advancing spark is necessary.
How does CRDi work in a fuel injection system?
CRDi ensures the fuel injection timing, quantity of fuel and atomisation or fuel spray are controlled electronically using a programmable control module. This allows multiple injections at any pressure at any time (within pre-defined limits), providing a level of flexibility which can be exploited for better power,…
How is the length of the fuel injection system determined?
The duration of the injection system depends on the length of time and the position of the valve. The amount of the fuel injected in the cylinder is depends on the duration, size and number of holes in the nozzle tip and the fuel pressure and air pressure in the cylinders.

Do you need different ignition timings for different engines?
Engines require different ignition timing depending on the load and engine speed. By “require”, of course, I mean “it would be nice to have if you want maximum torque output”. As you said, it’s a good hack in the sense that he got it to work. It does add complexity however, and without variable timing it doesn’t really give much benefit.
