Surbo System's Energy Analysis For Diesel Engines

Here is a study of what happens when the Surbo acts on a diesel-engined vehicle. It explains why the Surbo can bring the engine to its rpm red line with just 1/2 accelerator pressure, when most diesel vehicles need full accelerator pressure for the same. The reasons are air pressure accumulation, the Surbo's internal vortex air suction and output jet pressure, and better air scavenging through the Surbo Sytem's components (in {}).

Diagram below shows the air pressure accumulation within the Surbo system as the Surbo is activated through Stages 1 to 3.

This diagram shows the air flow through a Surbo-assisted diesel engine

where P1 is the initial inlet absolute air pressure, P2 is the Surbo's pressure setting, and P3 is the back pressure formed by the temporarily decreased acceleration.

Stages/ {Surbo System Component} {Surbo (red), presses air into grey pipe} {Oil chamber, in orange} {Governer, controlled by accelerator, in white box} {Intake manifold, in light grey} {Engine, bottom block in pink} {Exhaust, not shown}
initial acceleration (Stage 1) air flows straight through is pressed to inject diesel for acceleration normal absolute pressure is sole energy source
pressure accumulation (Stage 2) begins to cross-jet and form vortex internally fills up with engine back pressure is held still for 1 second to reduce engine acceleration, to generate a back pressure towards the Surbo fills up with engine back pressure cylinder pressure increases due to lessened acceleration but air still rushing in exhaust back pressure increases, ready to blast air out
vortex (Stage 3) Surbo spins air within itself, drawing more air in acts as air pressure accumulator is pressed slightly more and varied slightly around half way point half accelerator pressure means half as much diesel injected higher cylinder compression because of moderately increased air pressure blasts air out instantly because exhaust already under full back pressure
scavenging: pulling gases through (Stage 3 and afterwards) Surbos's internal vortex suction pulls air in harder than before half accelerator pressure prevents over-fueling and smoke higher air density imparts more force to air to overcome flow friction losses abundance of air to completely burn the diesel injected higher mass flow to push through exhaust or turbocharger along it
