(mechanical engineering)

The highest pressure in an engine cylinder during combustion.

Eventually, even the peak firing pressure (pfp) was constrained to a relatively 'common' value of 200bar on recent engines, in order to avoid compromising too much the engine design for keeping the mechanical efficiency at part load on a high level [6].

Other significant improvements included lowering of the turbo speed by 400 rpm (resulting in longer turbo life cycles) and a drop in peak cylinder firing pressure by as much as 90 psi (for longer power pack life).

Fuel injectors still progressing in solving emissions problems

Experimental investigation of In-cylinder pressure was done and the engine's ignition timing and injection duration was calibrated to operate the engine below peak firing pressure limits, without knocking.

Initial development of a E85 fueled, multi cylinder, turbocharged, spark ignited, heavy duty engine

This variation of pressure from valve-to-valve, even though the average pressure in the manifold is relatively steady, causes high cycle-to-cycle variations in the firing pressure.

Fuel control system updates older natural gas engines

It used to be that the peak firing pressure on a diesel was 150 bar, and it's now 175 bar," he says.

Conventional engines: not dead yet; Fuel cells and hydrogen may get all of the headlines, but gas and diesel internal combustion engines have a lot left to offer

This, along with the redesign of the precombustion chamber and the cylinder head, creates a more controlled and gradual firing pressure within the cylinder -- all of which leads to reduced engine noise at low engine rpm.
