The PROMPT is a
state-of-the-art cylinder kit analysis model. PROMPT
6.x is a fourth- generation cylinder kit model, that was developed to
provide an effective analysis and methodology that allows you to
understand the effect of more than forty dimensional variables on
cylinder kit performance. This PROMPT, an input tree to access
data entry screens.
Cylinder kit
dimensional data is entered through use of an input tree to access
data entry screens.
By using
combustion pressure data from an engine, the PROMPT model can be
used to optimize mean value, tolerance, and relationships among the
variables at specific speed, and load conditions.

This
model has been successfully applied to improve the performance of Small
industrial/lawn mower engines, Automotive engines, Diesel engines ranging
in size from a few horsepower to several thousand horsepower, and
High-performance (race) engines.
In order to
achieve this improved performance, the model utilizes entered
cylinder kit geometry data and the combustion pressure diagram
developed in the engine at the speed and load conditions of
interest.
The PROMPT treats
the cylinder kit as a series of orifices/accumulator volumes to
calculate, Blowby (quantitatively), Oil consumption (qualitatively),
Friction (quantitatively), Hydrocarbon emissions (contribution of
piston/rings).
